    Hi Frank,

    See below selection table for your reference:

    I suggest you can choose the TIDA-010250 as the example.

    See below migration guide for your reference: (the official release is scheduled by April).

    Sal,

    thanks for sharing.

    I run reference project TIDA-010250 but I don't connect DRV evm. It always run into below and disable the PWM.

    if(HAL_getRawHVdieFaultStatus())
    {
    HAL_DisablePWM();

    register is as below.

    any idea? Anything wrong do I set?

    I follow migration guide to change the code. I connect LP-MSPM0G3507 + DRV8311 EVM. 

    it also stop PWM at the same place.

    BR,

    Hi Frank,

    This is due to the Timer detect the Fault signal.

    (Due to E2E system issues, I can not upload anything here, please refer to Chapter 7.2.2 DIfferent Pin for PWM Fault Pin)

    Please check if the fault pin has low pulse which will trigger this HV_DIE fault.

    Users can unselect the enable fault handler in SysConfig to diable this function.

    B.R.
