Hi,

Quick question. Can you write to a rt device (say "rtser0") from the
main thread, ie not in a rt_task?

Thanks in advance.

Regards,

Short answer: Nope.

Longer version: You must call this service over a Linux task that was
shadowed for use with Xenomai. That can also be the main thread of some
application, though (check rt_task_shadow if use the native skin).
