Thank you for your interest in NXP RT produt, I would like to provide serivce for you.

Please check your on board debugger, CMSIS DAP or others?

The on board IMXRT1050-EVKB debugger can support CMSIS DAP and JLINK.

You can find it from:Control Panel\Hardware and Sound\Devices and Printers\unspecified

If it is the DAPLINK CMSIS DAP, it means your on board debugger is CMSIS DAP, you need to chose the CMSIS DAP In the keil.

From your picture, your MDK didn't select the correct debugger interface.

Please refer to my picture choose the correct debugger.

Wish it helps you!

If you still have question about it, please kindly let me know.

Have a great day,

Kerry

Hi Rita,

My debuger is on board CMSIS DAP, please refer attached capture.

The error is either "RDDI-DAP Error" or "SWD/JTAG Communication Failure" when changing Max Clock.

Have a great day!
