Interesting the comment above the function suggest it wouldn't block and didn't specify it's not allowed to be executed while in an interrupt. https://github.com/apache/incubator-nuttx/blob/9a53601ba993d43684328dcae8750acb00a34cc7/sched/semaphore/sem_trywait.c#L45-L48 The reason why it's called under...
IOB is shared mechanism used for different stacks. So on a multi-stack system where `CONFIG_IOB_HEADSIZE>0` all stacks are affected, maybe this is even a design limitation of the current IOB...
A Zero-copy ethernet solution would be indeed a great addition, when implementing a enet driver myself I noticed as well that packets are double stored and have a unnecessary copy...

You might want to backport this patch as well. https://github.com/apache/incubator-nuttx/commit/51a845ce54e38ca6ecc13c2fd7029802cb07076f It allows you to listen with multiple applications to the same CAN peripheral We could also consider upgrading the NuttX...

Not sure what you mean by a prototype using pyuavcan, you can easily make a register response in yakut right? Regarding that piece of code you can easily generate a...
