Segger J-Link with Adafruit Feather nRF52832

The Adafruit Feather nRF52832 provisions pads for a surface-mounted 2x5 0.05" SWD connector.
​
Adafruit provides a full tutorial for debugging at Can I use GDB to debug my nRF52832? with Segger J-Link and JLinkGDBServer.

Picture
Soldering the SWD connector was neither easy nor difficult, it just required a sharp solder iron tip and patience. Let's hope next iteration of the board would come with the SWD connector soldered.

Because the Adafruit Feather nRF52 boards run on FreeRTOS, J-Link requires specific plug-ins. 


​Ozone manages FreeRTOS better than the command-line J-Link utility and is thus strongly recommended. 
Picture
However, Ozone requires a specific procedure.
  • First, executable must be uploaded.
  • Then, start debugging with Ozone with the Attach to running program option.

F
or other boards, both steps are combined with the Download and Reset Program option.
