J-Link OB not recognized on USB anymore (nrf5340_audio_dk)

[hegdi]

the on-board J-Link is not showing up on USB anymore besides the FTDI chip still being detected.

So it's not detected anymore by neither JLinkConfig nrfprog or any other tool (obviously).

Is there a way to re-flash the J-Link or force it to boot-loader for recovery?

Kind regards

On older DK versions you just have to hold down reset when connecting to USB/power.

Warning: You will have to install the interface MCU firmware binary to un-brick the DK.

Well yes, indeed, for older DK's that was the case. Unfortunately not this one. I tried already the reset buttons and all other buttons, while plugging in USB, to no avail.

Hi Dirk,

The newer boards that we have uses the nRF5340 as the debugger and it is not possible to re-flash the J-Link.. I will check internally wat can be done in this case..
