This time it’s a different matter. I want to make sure that it runs on Linux on the three cores of the A53 in zynqMP, and that it works by booting together in FreeRTOS. However, at Linux boot time
“Assert failed in file port.c, line 658”
“Assert failed in file port.c, line 609” has an error and is stopping operation. I think it’s an Interrupt related error, but I don’t know how to solve it.
