mu irq priority

[panezion]

my dev board is imx8mq Evk
is there any document about the mu irq priority.

I’m using rpmsg lite on m4 side and found that the mu irq has almost the highest priority of my running context can I set the mu irq priority like the nvic_xxx way?

Hi xiang

one can look at #define APP_MU_IRQ_PRIORITY in

rpmsg-lite/rpmsg_platform.c at master · NXPmicro/rpmsg-lite · GitHub 

Best regards
