Hi @bobbychauhan ,

   Please help to check, whether your board is powered on or not, I mean, the power LED is lighting or not? Make sure your board is powered successfully.

  Then, if still have issues, it normally caused by the invalid demo is downloaded to the flash, cause the boot issues, then it will also report the debugger issues. When meeting this issues, you can enter the serial download mode, do the mass erase, and change back to the internal boot mode again.

  You can refer to my post:

https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/RT-board-recovery-for-debugger-connect-issues/ta...

  Please try it at first.

  If you still have issues, just kindly let me know.

Best Regards,

Kerry

Hi @kerryzhou,

Thank you for your response.  I followed the steps you mentioned in your post, and it resolved the issue I was facing with the RT1160 EVK board. Here's a recap of the steps I followed:

1) To enter serial download mode:

    i) Set the SW1 switches as follows: 1-OFF, 2-OFF, 3-OFF, 4-ON

    ii) Power off the board and then power it on again, or press the Reset button.

2) Performed a mass erase in the IDE.
