Effect of CPU reset (HW) command on AM335x chip

Vasili Galka

Hi,

What exactly does this command perform?

How does it differ from the "System reset" command that pulls the chip nRESET pin? And from SW reset command that just clears the chip registers?

Best,

The CPU reset (HW) toggles ICECrusher reset request to PRCM. This is a local HW reset for the MPU Subsystem.

The "system reset" will reset the entire device except the debug related logic, it has the same effect of toggling the chip nRESET pin but does not physically toggle the pin.
