This will + avoid requests of exactly MAXPACKET size and, hence, avoid so many + NULL packets. Also, fix the OUT request buffers size to exactly the + max packet size. It really cannot be any other size. +

        • +
      • + Fixed an error in NULL packet handling in the STM32 F1 USB device + controller driver: If the NULL-packet needed flag ever got set, + then it was not being cleared and infinite NULL packets resulted. + This only affects the CDC/ACM class and was the cause of the + failures using the USB CDC/ACM device as a NuttX console. With this + change the USB works well as an alternative NuttX console device for + the STM32 F1 family. +

-    * tools/mkconfig.c:  Logic that attempts to suppress buffered I/O
-      within the kernel is wrong.  sizeof(struct file_struct) must be
-      the same in both kernel- and user-spaces (2013-03-16).

-    * arch/arm/include/armv[6|7]-m/irq.h, and arch/arm/src/armv[6|7]-m/up_svcall.c:
-      Add support for nested system calls.  In the current design, this can
-      happen only under one condition:  When the kernel system call logic calls
-      back into user space in order to allocate user space memory.  So it is
-      expected that the maximum nesting level will be only 2 (2013-03-17).
-    * libc/stdio/lib_sccanf.c:  Correct an error in sscanf.  If %n occurs in
-      the format statement after the input data stream has been fully
-      parsed, the %n format specifier will not be handled.  Reported by
-      Lorenz Meier (and also earlier by Kate) (2013-03-17).
-    * drivers/serial/serial.c:  Support for O_NONBLOCK was not supported
-      in the "upper half" serial driver.  This is normally not an issue
-      because UART TX is almost always available, but it does become an
-      if the UART uses hardware flow control or if the a "lower half" is

-    * arch/arm/src/armv7-m/up_hardfault.c:  If the PRIMASK is used to disable

-      (2013-3-19).
-    * libc/ and mm/: Directories where the same sources files are used to

-      to keep those objects in separate directories so that they are not

-    * fs/fat:  Create an error in FAT file creation.  The FAT logic was
-      not making a distinction between directory non-existence and file
-      non-existence so when it you try to create a file in a non-existent
-      directory, it would create a file with the name of the missing
-      directory.  Reported by Andrew Tridgell (2013-03-30).
-    * Numerous files:  Changed the protoypes of up_create_stack() and
-      up_release_stack() so that is includes a task type.  Normally you
-      can get this type from the TCB parameter, but there are certain
-      conditions when the task type is not valid in the TCB when these
-      functions are called.  Only the prototypes were changed on this
-      big, initial checkin.  The next step will be to add logic to

-    * sched/sig_deliver.c:  When dispatching signals to user threads,
-      copy the siginfo_t from the sigq to the stack.  The signal queue
-      is allocated from kernel memory; however, the current stack is
-      the user's stack and the user code will be able to access the
-      signinfo_t data from the stack copy (2013-03-21).

-      re-archtecting of how signals are dispatched to user-space code
-      in the kernel build.  The original implementation was C-based
-      and simpler.  However, the C code intermixed with SVC calls was
-      not properly preserving registers.  The more complex, assembly
-      language version does not suffer from these issues.  I believe
-      the the kernel build can now be called "feature complete"
-      (2013-03-23).
-    * binfmt/binfmt_execmodule.c:  Here is a place where I forget
-      to update the call to sched_releasetcb() to pass the thread
-      type as the second parameter (2013-03-23).
-    * arch/arm/src/lm, kinetis, lpc32, and nuc1xx:  Add kernel build

-    * arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c:  SD card DMA
-      is now functional.  Thre may be some issues with DMA from CPU SRAM
-      which is apparently disabled in sleep mode; up_idle() always enters

-      configs/olimex-lpc1766stk, nucleus2g, zkit-arm-1769, and
-      lpcxpresso-lpc1768:  The initialization function for both the LPC17xx
-      SPI and SSP blocks was called up_spinitialize() which is the common API
-      definition of include/nuttx/spi.h.  But this raises a problem when the
-      MCU has multiple blocks for differ SPI implementations as does the
-      LPC17xx (and also as does other architectures like STM32 that have
-      USARTs that can serve as SPI interfaces as well).  These were renamed
-      to lpc17_spiinitialize() and lpc17_sspinitialize() in this case.
-      Problem reported by M. Kannan (2013-4-01).
-    * arch/arm/src/lpc17xx/lpc17_gpdma.c and lpc17_idle.c:  In sleep mode,
-      DMA can only be performed from peripheral SRAM.  CPU SRAM is shutdown
-      in sleep mode.  In order to simplify DMA memory allocation, the LPC17xx
-      IDLE will now hold off going to sleep mode if there is a DMA in progress
-     (2013-4-01).
-    * configs/open1788/src/lpc17_autoleds.c:  Reversed sense of the IDLE LCD.
-      It is now off when the LPC17 is sleeping and on when awake.  That is
-      much more useful because it provides a good visual indication of the
-      dynamic CPU load (2013-4-01).
-    * configs/open1788/src/lpc17_touchscreen.c and lpc17_ssp.c:  Add
-      support for the touschscreen on the WaveShare LCD (2013-4-01).

-      a major screw-up:  The Cortex-M0 has no BASEPRI register but
-      the current logic was using it to manage interrupts.  Switch
-      to using the PRIMASK.  This means that hardfaults will (again)
-      occur when SVC instructions are executed (2013-4-16).

-      tools (2013-4-17).
-    * sched/task_exithook.c:  Don't flush the streams until the
-      final thread of the group exits.  Flushing may cause the
-      thread to get suspended at a bad time and other threads in the
-      group may run while the exiting thread is in an unhealthy state.
-      This can cause crashes under certain circumstance.  This is a

-      Contributed by Lorenz Meier (2013-4-18).
-    * sched/task_deletecurrent.c and task_exit.c, arch/*/up_exit.c:
-      Renamed task_deletecurrent() and task_exit() since it really
-      handles the architecture independent part of _exit().  _exit()
-      is used internally, but if it is called from the user, it should
-      unregister any atexit() or on_exit() functions (2013-4-18).
-    * tools/kconfig2html.c: This is the beginning of a tool to
-      replace the hand-generated documentation of the NuttX configruation
-      variables with auto-generated documentation.  The initial checkin
-      is an incomplete, poorly structured prototype that I hope to
-      evolve into a useful tool (2014-4-20).
-    * libc/string/lib_strchr.c:  strchr(str, '\0') should return a
-      pointer to the end of the string, not NULL.  From Petteri
-      Aimonen (2014-4-22).
-    * fs/fat/fs_writefat.c: mkfatfs was writing the boot code to the
-      wrong location.  From Petteri Aimonen (2014-4-22).
-    * Documentation:  The NuttX documentation now expects to find an
-      auto-generated version of the configuration variable documentation
-      at Documentation/NuttXConfigVariables.html (2014-4-22).
-    * arch/arm/src/lpc17xx/lpc17_adc.c:  Only one ADC pin was configured.
-      Need to configure all that are in the ADC0 set.  From MKannan
-      (2014-4-23).
-    * configs/zkit-arm-1769/src:  ADC and SPI/USB MSC updates from
-      MKannan (2014-4-23).
-    * arm/src/armv7-m/ram_vectors.h and arm/src/armv7-m/up_ramvec_initialize.c:
-      Fixes to RAM vector logic from Paul Y. Zhang (2014-4-23)
-    * tools/kconfig2html.c:  Improve behavior of Expand/Collapse
-      Table of Contents; Handle errors in parsing of strings and in
-      some uninitialized variables.  Add an option to use jQuery.
-    * tools/mkconfigvar.sh: Fix make target (2014-4-23).
-    * sched/exit.c, pthread_exit.c, task_exit.c, task_delete,c and
-      task_exithook.c:  For pthread_exit(), move some logic to an early
-      point in the exit sequence where the task may need to block.  Add
-      conditional logic in the lower end of the eixt logic kicked off by
-      _exit() to prohibit blocking after the task has been torn down and is
-      no longer cabable of blocking (2014-4-23).
-    * arch/arm/src/common/up_initialize.c: Add missing registration
-      of /dev/zero.  Registration of /dev/null should depend upon
-      conditional compilation.  From Ken Pettit (2014-4-24).
-    * arch/*/src/common/up_initialize.c:  Same change required to other
-      architectures (2014-4-24).
-    * arch/arm/src/kl/kl_clockconfig.c and configs/freedom-kl25z/include/board.h:
-      Modify out PLL configuration so that it uses the values in
-      board.h;  Fix PLL settings in board.h so that the correct core
-      and bus clock frequencies are generated. (2014-4-24).
-    * arm/src/kl/chip/kl_memorymap.h, kl_sim.h, andkl_uart.h:  Correct some
-      register definitions (2014-4-25).
-    * arch/arm/src/kl/Kconfig, kl_lowputc.c, kl_serial.c, and kl_config.h:
-      No UART3-5 (2014-4-25).
-    * arch/arm/src/kl/kl_serial.c:  Various fixes to various files in the
-      KL architecture directory as need to get the interrupt-driven
-      serial driver to work.  The Freedom KL25Z NSH configuration now
-      works (2014-4-25).
-    * include/nuttx/assert.h, arch/*/src/*/up_assert.c, and other file:
-      Remove up_assert_code().  While asserting with an encoded value
-      could be a good feature, the codes have not be well utilized nor
-      documented.  Give that situation it is better to remove the API
-      and reduce the footprint a little (2014-4-25).
-    * drivers/serial/Kconfig and arch/*/src/*/*_serial.c:  Add
-      compilation so that the useless TIOCSERGSTRUCT ioctl logic
-      is not build unless CONFIG_DEBUG and CONFIG_SERIAL_TIOCSERGSTRUCT
-      are defined.
-    * sched/task_delete.c and task_terminate.c:  Most task_terminate()
-      out of task_delete.c into its own C file.  This should prevent
-      dragging task_delete() into the link when it is never called.
+    * arch/arm/src/lpc17xx/lpc17_i2c.c:  Interrupts were not being
+      re-enabled in the I2C intialization function (2013-4-30).
+    * net/sendto.c:  Added skeleton of implementation of send timeouts
+      for UDP.  However, this functionality really does not make
+      sense, so it is disabled in the code (2013-4-30).
+    * drivers/mtd/mtd_partition.c:  Support capability to clone one
+      MTD driver into several, MTD partition drivers, each of which
+      can manage a sub-region of the FLASH (2013-4-30).
+    * configs/sim/nxffs:  Converted to use the kconfig-frontends
+      tools (20130-4-30).
+    * configs/sim/mtdpart:  A new configuration to test MTD
+      partitions (2013-4-30).
+    * configs/sim/mkroe-stm32f4:  Support for the MikroElektronika
+      Mikromedia for STM32F4 development board (from Ken Pettit, 2013-4-30).
+    * fs/smartfs:  Add Ken Pettit SMART FS (2013-4-30).
+    * include/nuttx/mtd.h and most MTD drivers:  Add support for
+      (optional) method to perform byte oriented writes if so configured
+      (2013-5-1).
+    * arch/arm/src/kl/chip/kl25z128_pinmux.h:  Corrections fo the
+      pin multiplexing definitions from Alan Carvalho de Assis
+      (2013-5-2).
+    * drivers/mtd/mtd_partition.c:  Fix a few bugs and add support for the
+      (option) byte write method (2013-5-3).
+    * arch/arm/src/kl:  Repartitioning of definitions in header files
+      from Alan Carvalho de Assis (2013-5-3).
+    * drivers/mtd/smart.c, fs/smart, and other files:  SMART file system
+      now makes use of the MTD byte write capabilities when present (from
+      Ken Pettit, 2013-5-3).
+    * drivers/mtd/m25px.c:  Some rearchitecting to use the byte write
+      capability (when possible) and to use 4KB sectors for the erase block
+      size when the part supports it (Ken Pettit, 2013-5-3).
+    * configs/pirelli_dpl10: Adds a configuration for the pirelli phone
+      (from Craig Comstock via Alan Alan Carvalho de Assis, 2013-5-3).

+    * configs/pirelli_dpl10/nsh_highram:  Converted to use the
+      kconfig-frontends tools (2013-5-5).
+    * drivers/lcd/mio283qt2.c:  LCD was not being selected in setpower
+      method (also not being deselected in hwinitialize function)
+      (2013-5-6).
+    * arch/arm/src/kl/kl_gpio.c and .h, configs/freedom-kl25z/src/freedom-kl25z.h,
+      and configs/freedom-kl25z/src/kl_led.c:  Fixes LEDs on the Freedom KL25Z
+      board (2013-5-6).
+    * arch/arm/src/kinetis/kinetis_pin.c and arch/arm/src/kinetis/kinetis_internal.h:
+      The Kinetis GPIO logic had some of the same issues as did the
+      Kinetis L (2013-5-6).
+    * arch/arm/src/stm32/stm32_idle.c: Add an option to conditionally disable
+      the "wfi" sleep mode.  This is needed with certain JTAG debuggers to
+      to prevent the debug session from begin disconnected.  From Ken Pettit
+      (2013-5-7).
+    * configs/mikroe-stm32f4/fulldemo/, nx/, nxlines/, nxtext/:  Add more
+      configurations for the Mikroelektronika Multimedia STM32-M4 board.
+      From Ken Pettit (2013-5-7).

+      STM32 F4 touchsceen working.  From Ken Pettit (2013-5-11).
+    * configs/*/nxwm:  Default priorities for NxWidget and NxWM threads
+      should be 100, not 50, to be consistent with other default priorities.
+    * configs/hymini-stm32v/buttons, nsh, and nsh2:  Configurations converted
+      to use the kconfig-frontends tools (Laurent Latil, 2013-5-14)

+      Reported by Ken Pettit (2013-5-17).
+    * nuttx/syscall/syscall.csv:  Type of first parameter of on_exit() is
+      wrong. Reported by Ken Pettit (2013-5-17).
+    * configs/mikroe-stm32f4/kernel/, kostest/ and scripts/:  Add kernel build
+      support and kernel mode OS test example for the the MikroElektronkia
+      MultiMedia STM32 M4 board.  From Ken Pettit (2013-5-17).
+    * arch/arm/include/stm32/chip.h and arch/arm/src/stme32/chip/stm32l15xxx_pinmap.h:
+      Beginning of support for the STM32L15X family (2013-5-18).
+    * arch/arm/include/stm32/stm32l15xxx_irq.h and arch/arm/src/stm32/chip/stm32l15xxx_vectors.h:
+      Support for STM32L15X interrupt vectors (2013-5-18).
+    * arch/arm/src/stm32/chip/stm32l15xxx_gpio.h and related STM32 GPIO files:
+      Add GPIO support for the STM32L215X (2013-5-18).
+    * arch/arm/src/stm32/chip/stm32l15xxx_memorymap.h: STM32L215X memory map
+     (2013-5-18).
+    * arch/arm/src/stm32/chip/stm32_pwr.h, stm32fl15xxx_rcc.h, and stm32l15xxx_syscfg.h:
+      More updates for the STM32L152 (2013-5-19).
+    * configs/stm32ldiscovey: Configuration for the STM32L-Discovery board.
+      Still does not build on initial check-in (2013-5-19)
+    * STM32L15X:  Add DMA and UART start.  Correctly initialize the heap
+      (2013-5-19).
+    * arch/arm/src/stm32/stm32l15xxx_rcc.c chip/stm32_flash.h:  Add RCC PLL
+      and FLASH configuration logic for the STM32L152X (2013-5-19).
+    * include/nuttx/usb/audio.h:  Typo- and bug-fixes from Ken Pettit
+      (2013-5-19)
+    * audio/, drivers/audio, include/nuttx/audio.h:  Add a new audio subsystem

+      Holtzberg (2013-5-20).
+    * arm/src/stm32/chip/stm32l15xxx_vectors.h:  After correcting errors in the
+      vector definition file, the STM32L-Discovery NSH port now seems to be
+      fully functional.  Also fixed an error that was causing the LEDs to be
+      controlled incorrectly (2013-5-21).
+    * arch/arm/src/stm32/chip/stm32_lcd.h: Add definitions for STM32L15X
+      segment LCD (2013-5-21).
+    * configs/lm3s6965-ek/discover: Add an example configuration for UDP
+      discovery tool on the lm3s6965-ek board.  From Max Holtzberg
+      (2013-5-21).
+    * audio/, drivers/audio, include/nuttx/audio:  Added a callback interface
+      to the Audio upperhalf driver for dequeueing, reporting async events,
+      etc. Also included is some initial work for the VS1053 driver.  From
+      Ken Pettit (2013-5-21).
+    * include/nuttx/audio/audio.h:  Moved from include/nuttx/ to include/nuttx/audio.
+      (2013-5-21).
+    * configs/lm3s6965-ek/tcpecho: This configuration builds the simple TCP

+    * configs/stm32ldiscovery/src/stm32_lcd.c:  Framework for support of the
+      STM32L-Discovery's segment LCD (2013-5-22).
+    * fs/fs_poll.c:  Poll setup/teardown logic should ignore invalid (i.e.,
+      negative) file descriptors.  Max Holtzberg (2013-5-23).
+    * net/net_poll.c: When readahead data is available, the network poll
+      logic should set POLLIN (or POLLRDNORM), not POLLOUT.  Max Holtzberg
+      (2013-5-23)
+    * fs/fs_poll.c:  Actually, it should also set revents == 0. (2013-5-23).
+    * libc/misc/lib_slcdencode.c and lib_slcddecode.c:  Add logic to marshal
+      and serialize special SLCD intermixed with normal ASCII data (2013-5-23)
+    * configs/stm32ldiscovery/src/stm32_lcd.c:  STM32L-Discovery's segment LCD
+      is code complete but completely untested (2013-5-23).
+    * include/nuttx/fs/ioctl.h, include/nuttx/lcd/slcd_codec.h, and
+      configs/stm32ldiscovery/src/stm32_lcd.c:  Add SLCD ioctl commands to get
+      SLCD geometry, set bars, and manage contrast (2013-5-23).
+    * configs/stm32ldiscovery/src/stm32_usb.c:  This file and all references
+      to USB removed for the STM32L-Discovery.  While the chip supports a
+      USB device, the board does not (2013-5-24).
+    * arch/arm/src/stm32/stm32_lse.c:  Add support for the STM32L CSR register
+      and for the LSE LCD clock source (2013-5-24).
+    * The STM32L-Discovery segment LCD is now functional and the README file
+      includes instructions for adding the apps/examples/slcd segment LCD
+      test as an NSH "built-in" command (2013-5-24).
+    * configs/pcblogic-pic32mx:  Converted all configurations to use the
+      kconfig-frontends tool (2013-5-25).
+    * configs/pcblogic-pic32mx/src:  Renamed files using pic32mx_ vs up_
+      prefix.  Enable building of LCD1602 LCD (2013-5-25).

+      (2013-5-25)
+    * configs/stm32ldiscovery/src/stm32_lcd.c: Now supports ioctl to get
+      cursor position (2013-5-25).
+    * include/nuttx/lcd/slcd_ioctl.h:  Moved ioctls commands and structures
+      from slcd_codec.h (2013-5-25)
+    * libc/misc/lib_slcdencode.c and lib_slcddecode.c:  Several encoding
+      and decoding bug fixes (2013-5-26)
+    * configs/sure-pic32mx:  Converted all configurations to use the
+      kconfig-frontends tools, cleaned up the directory structure and
+      naming to match some of the more recent configurations, and added
+      a segment LCD driver for the board.  The initial checkin of the
+      LCD driver is just a clone of configs/pcblogic-pic32mx/src/pic32mx_lcd1602
+      and it not yet expected to be functional (2013-5-26).
+    * include/nuttx/lcd/slcd_ioctl.h and all SLCD drivers:  Rename geometry
+      structure to attributes;  Move MAX contrast to attributes.  Add
+      attribute and ioctl commands to get and set LCD brightness (2013-5-27).
+    * configs/sure-pic32mx/pic32mx_lcd1602.c:  This driver appears to
+      fully functional (at least to the extent that it has been tested)
+      (2013-5-27).
+    * arch/mips/src/pic32mx/pic32mx-usbdev.c:  Fix NULL packet handling in
+      the PIC32 USB device driver.  Without this fix the CDC/ACM driver
+      cannot be used reliably with the PIC32 USB.  With this change the
+      configs/sure-pic32mx/usbnsh configuration works great (2013-5-28).
+    * configs/sure-pic32mx/src/pic32mx_nsh.c:  The NSH configurations will
+      support the USB monitor applications (2013-5-28).
+     nuttx/arch/arm/include/stm32/chip.h, src/stm32/Kconfig, src/stm32/chip.h,
+      and src/stm32/chip/stm32f103c_pinmap.h: STM32F103C4 and F103C8 chip
+      support from Laurent Latil (2013-5-28)
+    * configs/stm32_tiny: Add support for the STM32 Tiny development board
+      based on the STM32 F103C8T6 MCU (2013-5-28).
+    * arch/arm/src/stm32/stm32_usbdev.c:  Fix an error in NULL packet
+      handling:  If the NULL-packet needed flag ever gets set, then
+      it is not cleared and inifinite NULL packets result.  This only
+      effects the CDC/ACM class and was the cause of the failure of
+      configs/stm32f3discovery/usbnsh configureation which works great
+      after this change (2013-5-29).
+    * drivers/usbdev/cdcacm.c and pl2303.c and include/nuttx/usb/cdcacm.h:
+      Change the default IN request buffer size from 64 to 96.  This will
+      avoid requests of exactly MAXPACKET size and, hence, avoid so many
+      NULL packets.  Also, fix the OUT request buffers size to exactly
+      the max packet size.  It cannot be any other size (2013-5-29).
+    * .gitignore:  Clean-up of most all .gitignore files:  Make scope of
+      ignore to be only the current directory; Ignore .dSYM files in
+      directories where .exe's may be build.  Also, in Makefiles,
+      clean .dSYM files in directories where .exe may be built (2013-5-30).
+    * drivers/wireless/nrf24101.c/.h and include/nuttx/wireless/nrf24101.h:
+      Add new driver for the wireless nRF24L01+ transceiver.  From Laurent
+      Latil (2013-6-1).
+    * drivers/wireless/cc1101:  Move files in the cc1101 up one directory.
+      From Laurent Latil (2013-6-1).
+    * configs/stm32_tiny: Fix nRF24L01+ driver integration for the STM32
+      Tiny.  From Laurent Latil (2013-6-01).
+    * configs/sam3u-ek:  All remaining configurations changed to use
+      the kconfig-frontends tools (2013-6-2).
+    * arch/arm/src/sam3u/chip:  All SAM3U register definition files moved
+      to this subdirectory.  Naming of registers changed from SAM3U_ to
+      just SAM_.  This is in preparation for a SAM4L port (2013-6-2).
+    * arch/arm/src/sam3u:  Renamed files to sam_* vs. sam3u_*.
+      Eliminated sam3u_internal.h; instead uses individual header
+      files for each SAM interface block (2013-6-2).
+    * arch/arm/src/stm32/stm32f20xxx_rcc.c and stm32f40xxx_rcc.c, and
+      configs/mikroe-stm32f4/src/up_clockconfig.c.  Correct some bad
+      conditional compilation (CONFIG_ missing from setting name).  This
+      affects some STM32 FLASH pre-fetch settings.  From Lorenz Meier
+      (2013-6-2).
+    * arch/arm/include/sam34 and arch/arm/src/sam34:  The old sam3u/
+      directories were renamed sam34/ to make room in the namespace for
+      the SAM4L (2013-6-2).
+    * libc/stdio/lib_dprintd.c and lib_vdprintf.c:  Add dprintf() and
+      vdprintf() (the latter from Andrew Tridgell, 2013-6-2).
+    * sched/sem_holder.c:  Modify assertion that is reported to cause

+NuttX-6.28
+----------
+
+The 95th release of NuttX, Version 6.28, was made on June 14, 2013,
+and is available for download from the SourceForge website.  Note
+that release consists of two tarballs:  nuttx-6.28.tar.gz and
+apps-6.28.tar.gz.  Both may be needed (see the top-level nuttx/README.txt
+file for build information).
+
+Additional new features and extended functionality:
+
+    * File Systems:
+
+      - SMART FLASH file system (contributed by Add Ken Pettit).
+
+    * MTD (FLASH) Drivers:
+
+      - Add support of MTD partitions via a new MTD driver that manages a
+        set of MTD devices, each managing a subset of the FLASH region
+        managed by the parent MTD driver.
+      - Extended the MTD interface to provide an (optional) method to
+        perform byte oriented writes if supported by the FLASH part.
+      - M25Px driver re-architected to use the byte write capability (when
+        possible) and to use 4KB sectors for the erase block size when the
+        part supports it (from Ken Pettit).
+
+    * LCD Drivers:
+
+      - New interface definitions to support audio devices (from Ken Pettit)
+        and alphanumeric, segment LCDs.
+
+    * Wireless Drivers:
+
+      - Added new driver for the wireless nRF24L01+ transceiver (from
+        Laurent Latil).
+
+    * Calypso:
+
+      - Added support for the Pirelli DP-L10 phone (from Craig Comstock via
+        Alan Alan Carvalho de Assis)
+
+    * STM32:
+
+      - Added an option to conditionally disable the "wfi" sleep mode.  This
+        is needed with certain JTAG debuggers to to prevent the debug
+        session from begin disconnected (from Ken Pettit).
+      - Added support for the STM32L (STM32L15X/STM32L16x) family.
+      - Added STM32F103C4 and F103C8 chip support (from Laurent Latil).
+      - Added a new interface function, stm32_dmacapable() that can be used
+        to determine if DMA is possible from the specified memory address
+        (from Petteri Aimonen)
+
+    * STM32 Drivers:
+
+      - If CONFIG_STM32_DMACAPABLE is defined, the STM32 SPI driver now uses
+        stm32_dmacapable() to determine if it is possible to perform DMA
+        from the specified address.  This change is important for the STM32
+        F4 which may have SPI data buffers allocated on the stack in CCM
+        memory which cannot support the DMA (from Petteri Aimonen).
+
+    * STM32 Boards:
+
+      - Support added for the MikroElektronika Mikromedia for STM32F4
+        development board (from Ken Pettit) with the MIO283QT2 LCD and
+        touchscreen.  Several graphics configurations are included.
+      - The HY-mini STM32v board now uses the common SSD1289 driver
+        and supported the card detect interrupt.  Several new
+        configurations also added and some removed (from Laurent Latil).
+      - Support added for the R65105-based LCD that comes with some
+        HY-Mini STM32v boards (from Christian Faure).
+      - Added basic support for the STM32L-Discovery board.  Drivers
+        for the on-board segment LCD are included.
+      - Added support for the STM32 Tiny development board based on the
+        STM32 F103C8T6 MCU.  This includes support for the nRF24L01+
+        wireless on the board (from Laurent Latil).
+
+    * Stellaris LM3S/LM4F:
+
+      - Support added for a TI/Stellaris internal FLASH MTD driver (from Max
+        Holtzberg).
+
+    * Stellaris LM4F Boards:
+
+      - The LM3S6965-EK now has configurations for the UDP discovery tool and
+        for the TCP echo server (both from Max Holtzberg)
+
+    * Atmel ATSAM3/4:
+
+      - Reorganized, renamed, and updated directory structure to better
+        support additional members of the SAM3/4 family.
+      - Added support for both the ATSAM4S and ATSAM4L families.  The
+        ATSAM4S is similar to the ATSAM3U, but the ATSAM4L is quite a
+        different beast, really much more akin to the AVR32s SoCs but
+        with a Cortex-M4.
+
+    * Atmel ATSAM3/4 Boards:
+
+      - Added support for the Atmel SAM4L Xplained Pro development board.
+        This board features the ATSAM4LC4C MCU (Cortex-M4 with 256KB FLASH +
+        32KB SRAM).
+      - Added support for the Atmel SAM4S Xplained developement board.  This
+        board features the ATSAM4S16C MCU (Cortex-M4 with 1MB FLASH + 128KB
+        SRAM).
+
+    * PIC32MX Boards:
+
+      - Added support for the 1602 segment LCD on-board the Sure PIC32MX
+        board.  This board will now also support a USB NuttX console and
+        the USB monitor test program.
+
+    * Build System:
+
+      - Clean-up of almost all .gitignore files:  Made scope of ignore to be
+        only the current directory; Ignore .dSYM files in directories where
+        .exe's may be built.  Also, in Makefiles, clean .dSYM files in
+        directories where an .exe may be built.
+      - Standardize and consolidated all build-as-an-NSH-application
+        configuration settings.  Now only CONFIG_NSH_BUILTIN_APPS is
+        sufficient to build an application, test, or or example as an NSH
+        builtin application.
+      - Added support for a generic ARM, ARMv6-M and ARMv7-M Windows EABI
+        toolchains.
+
+    * Libraries:
+
+      - Added encoder/decoder logic to marshal and serialize special segment
+        LCD (SLCD) commands intermixed with normal ASCII data.  This is the
+        similar to the encoding/decoding logic that is used to marshal
+        special commands from a keyboard.
+      - Add dprintf() and vdprintf() (the latter from Andrew Tridgell).
+      - Add an application that may be built as an NSH builtin command that
+        will erase FLASH using a flash_eraseall NSH command (from Ken Pettit).
+
+    * Applications:
+
+      - Added an MTD partition test/examples.  Currently used with (1) the a
+        simulation configuration to test MTD partitions on a RAM emulation
+        of FLASH and (2) with the Mikroe STM32F4 configuration.
+      - Added a test/example to verify alphanumeric, segment LCDs.
+      - Added a simple single threaded, poll based  TCP echo server based
+        on W. Richard Stevens UNIX Network Programming Book (from Max
+        Holtzberg).
+      - Added several tests of the SMART block driver and file system (from
+        Ken Pettit).
+      - Added a runtime configuration for the UDP discover utility (from
+        Max Holtzberg).
+      - Added an example application to demo the nRF24L01 driver (from
+        Laurent Latil).
+      - New and modified NSH commands:
+        Added a -h option to the df command to show the volume information
+        in human readable form (from Ken Petit).
+        Add a new mksmartfs command (from Ken Petit).
+
+Efforts In Progress.  The following are features that are partially
+implemented but present in this release.  Most are expected to be fully
+available in NuttX 6.28.
+
+    * Audio System:
+
+      - A complete audio subsystem include CODECs, higher level management,
+        interface definitions, and audio drivers was contributed by Ken
+        Pettit.  This work has not been completely verified as of this
+        release and so is categorized as a work-in-progress.  At present,
+        progress is blocked due to issues interfacing with the VS1053
+        audio DAC on the Mikroe STM32F4 board.
+
+    * kconfig-fronted Configuration:
+
+    -  Conversion of old configurations to use the kconfig-frontends
+       tool is an ongoing effort that will continue for some time.
+       At this time, only 43% of the configurations have been converted
+       to use the kconfig-frontends tools.
+
+Bugfixes (see the ChangeLog for details).  Some of these are very important:
+
+    * Tasking:
+
+      - Modify assertion in the priority inheritance logic that is reported
+        to cause false alarm assertions.
+
+    * Kernel Build:
+
+      - Typo in syscall proxying logic corrected by Ken Pettit.
+
+    * Networking:
+
+      - Poll setup/teardown logic should ignore invalid (i.e., negative)
+        file descriptors (from Max Holtzberg).
+      - When readahead data is available, the network poll() logic should
+        set POLLIN (or POLLRDNORM), not POLLOUT (from Max Holtzberg).
+
+    * LCD Drivers:
+
+      - Correct power controls in the MIO283QT2 LCD driver.
+
+    * USB Device Controller Drivers:
+
+      - Change the default IN request buffer size from 64 to 96.  This will
+        avoid requests of exactly MAXPACKET size and, hence, avoid so many
+        NULL packets.  Also, fix the OUT request buffers size to exactly the
+        max packet size.  It really cannot be any other size.
+
+    * STM32 Drivers:
+
+      - Correct some bad STM32 F1 DMA definitions that crept into the system
+        a few months ago a broke STM32 F1 DMA (from Laurent Latil)
+      - Fixed an error in NULL packet handling in the STM32 F1 USB device
+        controller driver:  If the NULL-packet needed flag ever got set,
+        then it was not being cleared and infinite NULL packets resulted.
+        This only affects the CDC/ACM class and was the cause of the
+        failures using the USB CDC/ACM device as a NuttX console.  With this
+        change the USB works well as an alternative NuttX console device for
+        the STM32 F1 family.
+      - Correct some bad condition compilation in the RCC logic (CONFIG_
+        missing from setting names).  This affects some STM32 FLASH pre-
+        fetch settings (from Lorenz Meier).
+      - Change for hardware flow control support for STM32. The change also
+        fixes incorrect operation of USART2 and UART5 in current master
+        (from Lorenz Meier and Mike Smith).
+      - Fixed a backward conditional in USB OTG FS host controller driver
+        that prevented detection of disconnection events (from Scott).
+
+    * LPC17xx Drivers:
+
+      - I2C interrupt control.  Also correction for a single byte read
+        timeout error (from M. Kannan).
+
+    * Freescale Kinetis:
+
+      - Freedom KL25Z pin multiplexing and LED control corrections (from
+        Alan Carvalho de Assis)
+
+    * PIC32MX:
+
+     - Fix NULL packet handling in the PIC32 USB device driver.  Without
+       this fix the CDC/ACM driver cannot be used reliably with the PIC32
+       USB.  With this change the USB works well as an alternative NuttX
+       console device.
+
+    * Graphics:
+
+      - Default priorities for NxWidget and NxWM threads should be 100,
+        not 50, to be consistent with other default priorities.
+
+    * Applications:
+
+      - Remove the CONFIG_EXAMPLES_NXTEXT_NOGETRUN option from the NXTEXT
+        example.  The test logic was bad for the case where this options is
+        not selected.  Also, completed the empty Kconfig file.
+      - C++ name mangling was occurring when this example is built as an NSH
+        built-in application causing the entry to be undefined when called
+        from C code.
+      - Add some missing NSH library configuration values (from Lorenz
+        Meier).
