TMS570LC4357: Debug probe is not working

Hi Amarchand,

I want to know the following things:

1. Is it a custom board or TI-specific board? If it is a TI-specific board then it is a Launchpad or HDK board?

2. Which debugger you are using? Are you trying with any external debugger or onboard emulator IC?

3. Did you able to program it before or after trying on new board itself you are getting this error?

If you get this error after program the board with some code, then un-working code in the flash may prevents the CPU from entering a debug state.

Can you please 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 on your PCB board and hold it
4. Click “Connect Target” immediately after you release the nRST button
5. The board should be connected after couple tries

Thanks & regards,
