About AM335x Reset

Guru 15520 points

Hi,

I have a few question about AM335x Reset.

1.
In AM335x, there is nRESETIN_OUT which is warm reset.
I want to know the diffence between nRESETIN_OUT and
System Reset which we can reset the device from CCSv5.

I have checked the behavior of nRESETIN_OUT and System Reset by using AM3358EVM,
but it looks that there are no diffence so far.
Is there any diffence between these two resets?

2.
In CCSv5 Tool bar "Run"->"Reset", there are following resets:
===================
* CPU Reset (SW)
* CPU Reset (HW)
* System Reset
===================
I understand that "CPU Reset" will reset only CPU and System Reset will reset CPU + other peripherals.
But I can't uderstand the difference between CPU Reset (SW) and CPU Reset (HW).
What is the difference?

best regards,
g.f.
