hello chrischang0921,

we would like to have more details about your use-case.
did you want to put Tegra device enter suspend mode, and try to access the board via UART?
may I know what’s the functions/ commands you would like to send,
also, what’s your expectation results?
thanks

Hi Jerry:
Sorry for my late reply.
my original purpose is to observe the irq status to check my settings in PM mode by UART print logs.

After some modification, the wake-up is work so far. So this question is not in urgent.

By the way,
Refer to log messages, it seems put all CPUs into suspend mode, any chance to do this?
