AM335x nRESETIN_OUT and GPIO behavior

Guru 15520 points

Hi,

I have a question about AM335x warm reset.

At our customer, their customer board is having strange behavior
at external warmreset(nRESETIN_OUT) and GPIO.
nRESETIN_OUT are connected to reset switch.
If this reset switch is pushed, GPIO of C15/C16 (ZCZ package) will carry out
the same behavior as nRESETIN_OUT.

Is there any information for this behavior?

And sometimes when they push this reset switch, MPU will freeze until POR.
They are figuring out what will cause this freeze problem.

best regards,
g.f.
