Hi,
I'm trying to connect J-Link (J-Link Plus) to our FPGA board (with ARM Cortex-M0 in it) via SWD ports.
However, I got an error message "Could not power-up debug power domain" while trying to connect to the board.
What shall I check for it? Did I miss anything or steps (on our FPGA board or ...) ?
Here's some detail information
