CCS/TMS570LS3137: Not able to connect to target

Part Number: TMS570LS3137

Tool/software: Code Composer Studio

Hi Team,

After flashing the image on to TMS570LS3137 controller (using CCS8.0), we are getting below error:

(Error -2062 @ 0x0)
Unable to halt device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).

Can you please help in resolving this issue sooner?

Regards,
M.Sreenivasan.

    Hello Srenivasan,

    It looks like the code you programmed is making the part enter an exception state repeatedly. This prevents the CPU from entering a debug state, resulting in the behavior you observe. You need to try to erase the part, assert and release nRST to see if the erase command is able to halt the CPU and erase the flash.

    Please try this procedure to let CPU enter a debug state:

    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
