MSP432P401R: MCU device initialization failed - MSP-GANG

Bart

Part Number: MSP432P401R

We have an MSP432P401R-based PCB and have problems with reprogramming the MSP432.

We started writing firmware and used MSP-GANG Programmer to write the firwmare versions into the flash of the MSP432. So far it was successful, the GANG-Programmer always succeeded in erasing and writing the firmware. Today, after another firmware update (while trying out new features) it all stopped working. The Gang-Programmer is unable to find the MCU (it says: ERROR 23: MCU device initialization failed.)

On another PCB (same design), it works fine, so the last software update probably caused an error in the MCU and that is why it cannot communicate.
In this case, should a factory reset be performed on the MSP432? How to do it?

I have attached a screenshot of the gang programmer. The settings have not been changed and with these settings I can communicate and overwrite the flash memory of hte other PCB's MSP432.

Bart,

Try following the steps as described under Section 8.1 of the Code Composer Studio™ 7.1+ for SimpleLink MSP432 User's Guide.

What does the "Clear Locked Device" button do?

This person seems to have a very similar problem:

I believe that nothing changes when trying this button.

Sorry, I thought it was worth a try.

CCS is the only (other) way I know to do a Factory Reset.

Bart,

Have you tried following the steps described under Section 8.1 Factory Reset Without Password of the Code Composer Studio™ 7.1+ for SimpleLink MSP432 User's Guide.

Also, try using the SWD interface if you haven't already.

It is also possible to perform a factory reset without the JTAG/SWD interface by using the Flash Mailbox. Please take a look at Section 3 of this document: Configuring Security and Bootloader (BSL) on MSP432P4xx MCUs.

BR,

Seong
