How to Factory Reset a MSP432 from IAR

Maurizio von Flotow

Running the msp432p401r using IAR with the XDS200 debugger.

I believe I somehow corrupted the flash on my MSP432. The flash downloader gives an error "the flash loader program reported an error," and when I download without the flash loader no variables are able to hold a value other than '0.'

I'd like to perform a factory reset, but the only thread I've seen for this is for the pre-written script in CCS (e2e.ti.com/.../481391).

From the Family Guide I see its possible to send a factory reset over JTAG.

What are the steps for doing this with my XDS200?

Cheers,

Maurizio

Hi Maurizio!

The link in your post does not work, so I don't know where it leads to, so sorry if it is one of the things I link in.

Did you try this?

I was enjoy my new MSP-EXP432P401R launchpad. I was studing the Clock System (CS) so i tried to source the MCLK with the very low power oscillator VLO. My code

This document shows how to perform a factory reset (page 28). Hopefully one of those things works for you.

Edit: Stupid me - just saw you are using IAR. Maybe section 5.4.1 in this document?

DE:

The MSP is on a custom board, not a launchpad. So there is no option to use the XDS 110 debugger (which I believe is required for the CMSIS DAP driver).

In that same document (the final one you sent) was a discussion on how to do a reset using a Seggers J-Link, but again all I currently have access to is the XDS 200.

Cheers,

Maurizio

Any other thoughts on how to do this, Dennis?

Hi,

in IAR there is an automatic check if the device is locked for some debuggers. If this doesn't work you could try to unlock/do a factory reset with your XDS200 and CCS as described in www.ti.com/.../slau575 chapter 8.
For that the free version of CCS should be sufficient.

Regards,
Thorsten
