Rpmsg Router is new rpmsg transport layer, it can router the rpmsg messages to a cpu that not directly connected with local cpu by Rpmsg, For the rpmsg services, it is as if there is a real Rpmsg Channel between the local cpu and the remote cpu. For examples, there are three cpus: ap, cp and audio. ap and cp, ap and audio has share memory and be connected by Rpmsg VirtIO, so ap and cp, ap and audio can communicate with each other by Rpmsg, but cp can not communicate with audio direclty. [cp] <-- rpmsg virtio --> [ap] <-- rpmsg virtio --> [audio] With rpmsg router, the cp can communicate with audip by Rpmsg dereclty because the router in ap will forward the rpmsg message from cp/audio to audio/cp, like this: +<----- rpmsg router --> hub <-- rpmsg router ------>+ | | | [cp] <-- rpmsg virtio --> [ap] <-- rpmsg virtio --> [audio] Signed-off-by: yintao <yintao@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.
