• What is the priority between synchronous data abort and FIQ in Cortex-R5F?
    Hi, With Cortex-R5F, we have a case where a read to the L2 memory generates both a synchronous data abort and an FIQ with near-zero delay. We are reading from RAM while the RAM is in test mode and...
  • Cortex-M4 interrupt priority dynamically change while in ISR
    Hello, I am using STM32F407ZGT6 Cortex-M4 microcontroller. I am interested in changing the priority of a certain interrupt while servicing the same interrupt. Is that possible? More elaborately, lets...
