Tool/software: Code Composer Studio

Dear Sir,

When we are working and loading code on RM48L952 board, suddenly it went to secure mode.

So, please help us to unlock the secure mode as early as possible.

Best Regards,

    Hello Praveena,

    The device will not be locked if the AJSM is not programmed intentionally. To program AJSM, you need to generate the unlock code, and add memory section in linker cmd file. The JTAG is locked, you are asked to provide JTAG Unlock Passcode for unlocking. So I don't I don't think your device is locked.

    The problem might be caused by the code you have programmed. The code in the flash makes the CPU enter an exception state repeatedly, and the CPU is not able to enter a debug state. Can you please try those steps to restore your JTAG connection:

    1. Open the target configuration window, and launch the selected the configuration

    2. Switch to debug window

    3. Press the reset (nRST) button and hold it

    4. Click “Connect Target” immediately after you release the nRST button

    5. The board should be connected after couple tries
