What's the Zephyr's timers priority?

[Andrea Verdecchia]

A simple question: what's the priority of the expiry function of a timer in the Zephyr OS respect the other threads?

[Vidar Berg]

Hello,

The expiry function is run in the timers interrupt context (RTC) and will preempt any running threads.

Best regards,

Vidar

Thanks for you response. Is there documentation about it or about system's context priorities?

[Vidar Berg]

That the expiry function is run in the system clock's interrupt handler is documented in Zephyr here:
