I have an hardware-in-the-loop (HWITL) application that requires the in-the-loop bit run at a priority higher than MAX_SYSCALL_INTERRUPT_PRIORITY, otherwise FreeRTOS normal scheduling operations cause sporadic missed cycles. The HWITL bit is accumulating a buffer of measurements, and when that fills it needs to notify the (lower-priority) FreeRTOS-supported code that a buffer is ready. FreeRTOS task notification from-ISR API does not allow invocation from an ISR at higher priority than MAX_SYSCALL_INTERRUPT_PRIORITY.
So the question: Is there a sanctioned method of unblocking a FreeRTOS task from an ISR with priority higher than MAX_SYSCALL_INTERRUPT_PRIORITY? I know a few unsanctioned ways to do it
Thanks in advance for any pointers to a sanctioned method,
Best Regards, Dave
