AM2432: Warm reset(Warm boot) can be controlled by only SW without HW logic?

Hi Expert,

Can I ask a basic question and get your advice about a warm reset (warm boot)?

For warm reset, HW logic is required or it can be controlled by only SW? 

I would appreciate it if you explain the purpose of the warm reset and how it operates as well.

Regards,

Moonil

    Hi Moonil,

    The AM243x devices have support for both HW (pin-triggered) and SW (register-triggered) warm resets.

    The warm reset is a non-PORz/cold reset type. This means the reset can be issued with out powering down the board and repeating the power-on boot sequence. All devices implement these resets in an SoC-specific fashion.

    Please refer to chapter 5.3 Device Configuration - Reset of the AM243x Technical Reference Manual for additional details (link and Reset Sources screenshot below).

    Please follow up with any additional questions after reviewing the TRM.
