chenwen@espressif.com 0810fc45b7 xtensa/esp32s3: Fixed bbpll not calibrated from bootloader issue
1. Solve wifi may not work bug for bbpll not lock or not stable when enable RF.
  2. Improved timing tuning stability on ESP32-S3.
  The root cause of the issue:
	The application won't re-calibrate the BBPLL clock if it's already enabled.
	We add a force-recalib function in the app startup code to make sure even if
	the patch is applied by OTA, the clock is still re-calibrated.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
