IMXRT1050 - Error while debuging

dynamix — Wed, 30 Dec 2020 00:32:05 GMT

Hey folks,

Today, in the middle of debugging my program, I got some errors. After that, when I am trying to enter the debug mode and upload my program, I got the below errors:

I even tried to erase the flash, based on https://ask.embedded-wizard.de/3773/flashing-demos-on-imx-rt1050 , but I am getting the same error.

Could you please help me to fix this issue?

I really appreciate any help you can provide.

Edit: When I set the DIP Switch SW7 to OFF, OFF, OFF, ON, the error has changed to the below:

Put the board in ISP mode and see whether you can then program it.

Hi Mark,

Can you elaborate more on ISP mode? I am new to NXP boards and do not know how to do that exactly.

See section 4 of https://www.utasker.com/docs/iMX/uTaskerV1.4_iMX.pdf

For your board the switches are on the top and SW7 needs to be set to 0101 for ISP mode and returned to 0110 for RUN mode.

In ISP mode the debugger should be able to grab hold of the processor even if you have code that is otherwise causing it to fail connection.

Try also binaries from https://www.utasker.com/iMX/RT1050.html in ISP mode too if you still have difficulties (or if you want to make general development and learning more efficient)

Regards

Mark
