Bricked RT 1020 board?

[bp1979]

Hi,

I am using an RT 1020 EVK board. While trying to resolve an issue related to SRAM_DTC size, I uploaded the suggested configuration. Afterwards I was no longer able to upload anything new. 

I had a similar issue before, then I was able to recover following the "troubleshooting" steps in this guide. But even these steps no longer revive my board.

When I normally upload to my board using the debug icon in Xpresso, I get this error:

0 SWD devices detected.

How do I recover from this problem?

Problem solved. Took me long enough, but in the end this was the solution:

- power off board

- Set boot dip switches to 1-1-1-0

- Go to MCU Xpresso

- Generate a new project with the wizard (next next finish)

- Compile it (to generate a .axf executable)

- Press the flash icon

In the first dialog, I deselected all probes except CMSIS DAP.

In the second dialog, I changed nothing. The .axf was default selected.

- Press the "Run.." button, and let it upload.

- Power off board again

- Change back the dipswitches to 1-0-1-0

- Upload your program with debug button, and I was back online.

Hope this will help anybody who's struggling with this too.
