Occasionally I have this problem where I can not upload sketches to the Nicla. I double tap the reset button to trigger bootloader (causing it to flash green 3 times and then flashe red forever) then try to upload the sketch again but receive the same error message:
Open On-Chip Debugger 0.11.0+dev-gab95bac57-dirty (2021-05-11-10:45) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html debug_level: 2 adapter speed: 1000 kHz Error: unable to open CMSIS-DAP device 0x2341:0x60 Error: unable to find a matching CMSIS-DAP device the selected serial port does not exist or your board is not connected
Any ideas how to correct this issue?
It seemed you software environment didn't work. CMSIS-DAP device was not recognized. You could check your software installation.
I think I have seen this too, but solved using different ways.
One quick question: how about removing all the power (including the ESLOV cable) and re-plugging in the USB, will it solve the issue?
