Is there an xPortIsInsideInterrupt() function for the CortexA53? I do not see it be declared in freertos_bsp\psu_cortexa53_0\include\portmacro.h. Thanks.
I don’t think there is - but it should be easy enough to add by looking at one of the interrupt controller registers. If you implement one please let us know or create a pull request in the github repo https://github.com/FreeRTOS/FreeRTOS-Kernel
