TMS570LS1227: AJSM/TMS570LS1227/CCS

Part Number: TMS570LS1227

Hello,

TMS570LS1227ZWT was locked in an application by our team. When I try to unlock to MCU, this error appears in the images below. 

I put to dap_util and ajsm_util files right place. What is the reason for this error. How can I fix it?

    Hi 

    I followed the spna232a application note, I am using dap_util and ajsm_util files in this file. But I am getting the following error.

    To unlock the AJSM using gel file, please follow the procedure below:

    1. Modify the device xml file located in C:\ti\ccsxxxx\ccs\ccs_base\common\targetdb\devices\

        Please refer to spna232a for how to update the xml file

    2. The new xml file should be used for target configuration

    3. Generate testBoard.dat which is used by dbgauth tool. Open Target Configuration window, and click “test connection”, the testBoard.data will be generated and saved to your drive

    4. Place the AJSM folder in the standard gel file folder: C:\ti\ccsxxxx\ccs\ccs_base\emulation\gel\

        This folder include tap_util.gel, and ajsm_util.gel

    5. Modify the device gel file, and save it to gel folder

        please refer to spna232a about updating the gel file.
