K10 Micro controller stuck with config JTAG Disabled now NOT able to debug or update new program or erase all

Hi,

For testing the Hardware behavior I just disabled the JTAG pins in CPU config and downloaded the same program to the K10 MCU after power cycle the debugger was NOT able to get connected to it, then I realized I made a mistake by Disabling those pins how to I recover it back, I just have one prototype with me to do rest of my development please suggest some workaround.

Thanks,

Bhuvanesh S

Hello:

Try to connect to your board following next procedure:

1) Disconnect power from board.

2) Press and hold the reset button.

3) Power on the board

4) Run the debugger and while session is starting release the reset button.

You need to try this more than once.

If this does not work, P&E Micro has a recovery tool. You may download it from the next link after registering in the page:

Kinetis Recovery Tool

Hope this helps!

Regards!,
Jorge Gonzalez
