Hi
I am trying to upgrade the firmware in a BL652 using a Segger Jlink Edu. The BL652 is powered with 3.3v using a regulator off the JLink 5v output.
I had poor/unreliable firmware upgrade success by FTDI/USB/uart. I have had one module upgrade successfully after many attempts and one failure.
So I now need to use the JLink to recover module with the failed firmware upgrade
However I am not getting far with the Jlink and the Laird firmware upgrade process. Attached is a copy of my notes with some snap shots and log file
