Error: unable to find a matching CMSIS-DAP device #16
Description
I compiled simple_daplink.ino according to the Wiki and uploaded it to the XIAO_SAMD21.
I am trying to run DAPLink (XIAO SAMD21) using \Arduino15\packages\Seeeduino\toool\openocd, but the following message appears and DAPLink cannot be found.
Please advise on how to resolve this issue.
