recovering NRF52DK with bootloader

[danmcb]

I have a DK board with nRF52832 that I've been using several months with no problems.

Today I wanted to try an experiment and did some modifications to the startup ASM file, and since then I am unable to reprogram. Initially, the jLink wa sno longer visible from my host system.

I tried the following sequence:

- put the DK in bootloader mode

- drag-drop the latest jLink file into the bootloader

- cycle the power (now the jLink is visible)

- try this command (see screenshot below)

I can also try programming with a jLink programmer I guess. Other than that, is there anything I can do? logfile attached

seemed to be some kind of hardware/wiring issue. The problem went away of its own accord. You may close this ticket, sorry for wasting your time with it.
