Add an API for OTP (one-time programmable) memory on stm32h5. There are OTP APIs for non-STM32 platforms. There is no other API for STM32 so far with these names. Implement it in stm32h563xx_flash.c since the progmem abstraction also lives there. int stm32_otp_write(const uint16_t *data, uint16_t len, uint32_t offset); int stm32_otp_read(uint16_t *data, uint16_t len, uint32_t offset); The API allows cross-block reads/writes that don't necessarily start/end at block boundaries. The type of `data` is uint16_t * to express to the caller that the pointer should be 2-aligned. The natural size of OTP words is 16 bits. `len` is uint16_t for no strong reason. Preserve author's work. uint32_t stm32_otp_getlockstatus(void); Get a mask of blocks that are locked. A block being locked is considered as being one-time programmed.

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.
