Unable to program MIMXRT1060-EVKB using JTAG

Hi,

I am trying to program MIMXRT1060-EVKB rev B1 using JTAG. I followed the instructions and removed jumpers J9 and J10. But on J-Link Commander, I get the following message when trying to connect to it. The eventual task is to program my custom board with JTAG but if I can not program the evaluation board, then I have little chance.

Connecting to target via JTAG
InitTarget() start
Failed to power up DAP.
Executing Connect Under Reset
Failed to power up DAP.
Executing Connect Under Reset
_TargetHalt: CPU did not halt.
_TargetHalt: CPU did not halt.
_TargetHalt: CPU did not halt.
InitTarget() end - Took 811ms
Connect failed. Resetting via Reset pin and trying again.
InitTarget() start
Failed to power up DAP.

Hi @jahmed9 ,

Thanks for your interest in NXP MIMXRT series!

By default, the RT1060 only enables SWD. If customers need to use JTAG, you must program the relevant eFuses. Please refer to the RM:

Best regards,
Gavin
