Using SWD/JTAG on MIMXRT1011-EVK

I can't seem to get SWD/JTAG via J-link Ultra to work on the MIMXRT1011-EVK. I've already removed jumpers J61 AND J62, when I initiate debug in MCUExpresso it throws this error message:

2023-04-09 07_44_38-workspace - evkmimxrt1010_igpio_led_output_source_gpio_led_output.c - MCUXpresso.png

Debugging with CMSIS-DAP works fine.

Can you advise? Thanks

Forgot to mention, I connected the J-link to connector J55 on the EVK.

Hi @gfisys ,

Have you connect power to EVK?

Yes, I kept the CMSIS DAP usb connector (J41) plugged in to my PC and the board gets its power from that.

Am I supposed to use an external power supply instead? I didn't see anywhere that being a requirement for using external debugger/programmer.

Hi @gfisys ,

I tested on my board, it works fine. You can compare the jumper. If nothing different, you can switch the board to serial download mode can check if the MCUBootUtlity can find RT1011. If yes, you can use MCUBootUtlity to erase the flash, then try to connect with jlink again.
