The rwcnt (read word count) field in ctucanfd_frame_fmt_s was previously limited to 4 bits, allowing a maximum value of 15. This is insufficient to correctly represent the frame size (excluding the FRAME_FORMAT word) for larger CAN FD frames as required by the CTU CAN FD hardware. Increase the rwcnt bitfield width to support a larger range and adjust the structure layout so that ctucanfd_frame_fmt_s has a size that is a multiple of 4 bytes, as required by the hardware interface. This change improves correctness and robustness when handling larger CAN FD frames without affecting existing users. Signed-off-by: xucheng5 <xucheng5@xiaomi.com> |

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.
