MSPM0L1304: re-gain debug access via NRST

TISL

Part Number: MSPM0L1304

Dear E2E Support,

In Chapter 20.1.2 of our TRM, we mention that it's possible to re-gain debug access to a device which contains software that disables the SWD pins.

Could you clarify the exact sequence, duration, etc... we should apply on NRST?

Regards,

Hi there,

There may be some issues about this description. We are checking it.

If you want to regain debug access, you can consider other ways

Use bootloader to load the code
Before configuring these two pins, add a conditional judgment, or add a delay, so that you can access SWD at the beginning
Use an interrupt to re-config two pins

Thanks,

Yuhao
