nRF5340 debug interface not showing

[chris.c]

Hi,

I have a brand new nrf5340dk and the debug interface is not showing up when connected:


I have other nrf5340s that work so I'm sure its the board specific.

Board label says:

PCA1095

2.0.2
2024.21
1050008437

please can I have some help

Hi Chris,

It does look like there is an issue with the Debug chip on this DK. I will consult with the team on what we can do regarding the same. In the meantime, could you attach what you see when you try:

nrfjprog --ids

and also when you try:

nrfjprog --deviceversion

Neither of those commands return anything.

are you going to send me a replacement?

Hi Chris,

Yes, you can ask for a replacement for this from your supplier, from whom you obtained the DK from.

Please let me know how it goes.
