chBSemWaitTimeout

can one use chBSemWaitTimeout in interrupt context ?

ive got a shared data structure

A thread fills it with data.

RTC callback uses the data to update clk .


so need to protect the shared data structure, chBSemWaitTimeout fails in RTC callback

Re: Cortex-M33 and Arm TrustZone ?

So between the two OS's running you have some kind of API ?
