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,

Is your board being detected by the PC?

What about when you try the Programmer app?

Also, since the board shows up in the connected devices section, were you able to flash some basic sample onto it? Do you get errors?

Regards,

Priyanka

Hi Priyanka,

Yes the board is being by the PC:


Configurator tool shows:

If I try to flash something to it i get these errors:
 

If I try to recover the device I get:

Error recovering device. See the Output tab for more details.

Hi Chris,

Is it possible to attach a screenshot of what you see in the Programmer app when you select your device?

Also, do you have any logs from the Programmer app?

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

[chris.c]

Neither of those commands return anything.

are you going to send me a replacement? 

[Priyanka]

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.
