MSP432E411Y: Does a tool exist to recover locked MSP432 ?

Part Number: MSP432E411Y
Other Parts Discussed in Thread: UNIFLASH

The MSP432E TRM SLAU723 describes the sequence §3.3.4.3 Recovering a "Locked" Microcontroller, which will do a mass erase of the flash.

Is there a tool or script to do the required switching of the debug lines? I use a J-Link as a debugger with CCS through a JTAG interface.

Hello Jaako

Support for Unlock of the MSP432E4x devices should be handled by the CCS/UniFlash. The following application note has the details on the command line parameter that needs to be used

(command is ../dbgjtag -f @xds110 -Y unlock,mode=msp432e4)
These require one of the XDS debuggers and utility package version >= 7.0.98.0, which is not installed in either the stand-alone UniFlash 4.2.1 or CCS 7.3.0. I am currently upgrading my CCS to 7.4.0 and MSP432 SDK to 1.60.00.10. to see if these are updated.

Hello Jaakko,

It should have been available in CCS 7.3.0.00019 release. Please let us know if you do not see the version of the utility package after the update.

It is now at 7.0.100.1 (ccs 7.4.0. installation crashed half-way after trying to unsuccesfully download tirex iirc).
