“unable to find CMSIS-DAP device” is displayed when there is no DAPLink_XIAO.
Is the “simple_daplink_xiao.uf2” correctly installed on the XIAO_samd21 to be used as DAPLink?
Is the connection between Brick XIAO and DAPLink_XIAO correct?
What happens if use “0.11.0-arduino2” instead of “0.10.0-arduino7”?
