Took long time to reboot MCU

[harry_choi]

Hello Community,

I tried to reboot M7_0 core using Mcu_PerformReset() function or requested reboot to PMIC but it took very long time (over 3 seconds) to reboot.

VR5540 QM grade embedded on my board.

It looks VR5540 felt into deep fail safe mode and auto retry to wakeup after 4 seconds in fail safe mode.

When I use the watchdog in M7 core, I got the same result.

How can I reboot without this timeout ?

Thanks,

Harry

Hello harry,

That too much verify is the PMIC is working as should, since reboot takes 0.95 Secs
