Support USART waking from low power modes, allow keeping HSI running in STOP mode, allow specifying clock source for USARTs, add some missing register and field definitions. stm32 common Kconfigs: Add common STM32 UART config options USARTx_WAKE_FROM_LOW_POWER and USARTx_WUS for USART to cause wake up from low power modes. stm32h5 board configs: Allow board.h to choose the clock source of each USART. Allow board.h to express that HSI should continue running in low power modes. stm32h5 RCC: Set the clock source for each USART if specified in the board configs (STM32_RCC_CCIPR1_USARTxSEL). Keep HSI on in STOP mode if specified in the board configs (STM32_BOARD_HSIKERON_ENABLE). stm32h5 serial driver: Use the new USARTx_WAKE_FROM_LOW_POWER and USARTx_WUS in stm32h5 serial driver to wake from low power modes. Use the USART clock source specified by board configs. Enable FIFOs. Clear UE bit before initialization.

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.
Contributing
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.
