Flash OpenThread on Feather nRF52840 Express

Post by remydemy »

Hei everyone,

I'm currently trying to flash OpenThread onto the Adafruit Feather nRF52840 Express, with the help of this Guide .

Hardware & Software I use:
  • Adafruit Feather nRF52840 Express, connected via USB.
  • I tried it on macOS and Ubuntu.
  • JLink version: 17.0.2
  • nrfjprog version: 10.17.3 external
  • Bootloader: UF2 Bootloader 0.6.2
When I try to flash my device I get the following Error Message:

Code: Select all

ERROR: No debuggers were discovered.
NOTE: For additional output, try running again with logging enabled (--log).
NOTE: Any generated log error messages will be displayed.
And if I run it with the --log flag enabled I get this in a log file:

Code: Select all

So basically flashing doesn't work but I don't know why and I can't really see any problem in the log file. Has anybody any idea or can help me in any way?
Is it possible that I need the SEGGER J-Link Debugger?

Thank you for any help.

Best regards,
Emily
