likun17 bdac8c116a sensor_rpmsg.c: Fix that "stub" will be created when local core only has subscribers.
After the ap core subscribes to the 25hz batch 120ms data of the sensor core, it switches
to the cp core and subscribes to the 50hz batch 120ms sensor core data. At this time,
the data subscribed by the AP will be abnormally lost (12.5hz). Mainly because ap
subscribes to sensor core data earlier than cp. The subscription of cp will be broadcast
to the ap core at the same time, and the corresponding "path" already exists
under "/dev/uorb" of ap. Thus the ap will create a "stub".

There are some restrictions on the creation of "stub" to avoid this situation.

POSIX Badge License Issues Tracking Badge Contributors GitHub Build Badge Documentation Badge

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.
