CCS 10.4.0.00006 , can I use this to recover a "Locked" Microcontroller per section 4.3.4.3 of the CPU manual?

Hi Doug,

Sorry for the late replay as I was out office and just got back.

Please follow this app note and go to section 5.3.2 to use the dbgjtag.exe command to unlock the device to its factory setting. The dbgjtag.exe implements the section 4.3.4.3 of the CPU manual.

Hi Charles,

I don't have the XDS probes (but can purchase one), I have the Segger J-Link and Flasher probes. Can they be made to work?

Thanks, Doug

Hi Doug,

You will need to check Segger if their toolchain has the capability to unlock the device the implementation described in the datasheet.
