Cannot program my NRF5340 DK after some time. "Failed to write DebugPort register 2: Unknown Error in J-Link DLL"

[lukas.kirner]

After some time I picked up my NRF5340 DK again to continue my Matter samples. But I noticed I cannot program any sample to it. The Segger seems to work fine, as I'm able to use the Debug Out to program other Boards. After the searching the internet, I could not find any solution which is working for me. It seems like my board is bricked? The following logs are shown:

Nrf Desktop Programmer Log:

I tried it on several SDK and Toolchain versions like 2.6.2, 2.7.0 and the most recent 2.8.0.

I appreciate any help to get it up and running again before my NRF54L15 DK arrives :)

Hello,

Did you do any modifications to your board? Does Did you cut the solder bridge close to the USB port on the short side of the DK in order to measure current, perhaps? If so, you need to add a in header, shorting the two pins next to the solder bridge (or a jumper cable shorting them). On the DK it is marked SB40, and P22 is the one you should short if SB40 is cut). 

Can you please show me a close up picture of the board? Can you also write down what all the physical switches states are in on your DK? The ones that I am looking for are:

SW8 (I assume it is in ON)
SW10 (VEXT->nRF)
SW6 (nRF ONLY|DEFAULT)
SW9 (Li-Po VDD USB)

Also, please confirm that you are using the USB port marked J2, and not J3.

Best regards,

Edvin

Hello,

here is the top view of my board. I confirm that I did no soldering on the board, also I can confirm that I'm using J2 for Debugging/Programming. I use this board to program my Thingy53 and other external Boards using the Debug-Out port and pins. But programming the nrf5340 on the DK is not possible (of course all Debug-Out is disconnected at this time).

[Edvin]

I can see that the SolderBridges are intact and that most of the switches are in the right place. However, can you try to set the sw6 (nRF POWER SOURCE) to VDD? Does that change anything?

Best regards,

Edvin

[lukas.kirner]

Nope still the same problem.

I also tried to use the Debug-In to flash the nrf5340 from another board. But the same error also occurs.

Anything else I could do?
