MSP432E411Y: Trouble unlocking MSP432P4111 after locking it.

Mohamed Aboushenif

Part Number: MSP432E411Y

Tool/software:

Our product in the company i am working in uses the MSP432P4111 as part of a device. On of the things we want to do is to lock the microcontroller JTAG/SWD before shipping to customers, The problem now is that the MSP432P4111 microcontroller seems to be not supported anymore, there is few documentations about it, but I managed to use the MSP432P4XXSecurityAndUpdateTool from Texas Instruments. I used that tool to generate a hex file that locks the microcontroller. but I have trouble now unlocking it

I am using the XDS110 and XDS200 Debug probes. Also note that I am not using a BSL (bootloader). The aim at the end in my company is to automate the unlocking process.

Please note that we are still using MSP432P4111 , and will keep using it for some time as it is already installed at customers.

Hi,

Yes, MSP432P is EOL. I find this post that will help on unlocking the JTAG.

I want to note that i did both locking JTAG with password and also configuring factory reset with password and I do not want to use BSL. I want to perform the factory reset that I configured.
