Hello,
I've tried to understand the priority between different interrupts,
but did not find any information on this matter. Are there priorities
for interrupts ? Is timer priority highest ?
Regards,
Ran

`ps' has an option to show the priority of the interrupt thread and 50
is the default value. The timer interrupts does not run as a thread.

That is SoC specific and documented in the reference manual.
