PPK JLink error: Errorcode: CouldNotOpenDevice (0x4) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)

[Thomas55]

I am currently trying to use a nordic semi ppk and nrf52840 to read current in the nordic semi power profiler software.

I am able to flash the DK successfully (while P22 is jumped), I have cut SB40 under a microscope, and my data cable works, and is a data cable. I am not connected to the DK through any usb hubs, the usb cable directly connects to my pc. ( one end of cable in DK, one end in pc usb port) 

I have a log produced by nrfjprog -e --log for assistance troubleshooting.

The issue occurs when I attempt to connect to the DK in the NRF Connect Power Profiler App. The error output in the NRF Connect Power Profiler App console is as follows: 

14:41:37.131

Validating firmware for device with s/n 000683056321

14:41:38.180

Error while setting up device 000683056321: Error occured when close opened device. Errorcode: CouldNotOpenDevice (0x4) Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)

14:41:38.181

Deselecting device

The current code flashed to the DK is the ble_app_uart example from the 17.0.2 SDK

We have tried two different PPKs, with the switches on the PPK in the configuration described by the documentation, specifically:

SW2 is on DK, SW4 is on DK, and the COM switch is on DK.

When the PPK is on, LED2 is illuminated.

Any assistance would be appreciated. 

Thank you for your time.

Hi

From your description everything sounds correct. A few more things you can try. Please make sure that the DK is turned OFF before you mount the PPK onto the DK, then turn it ON afterwards and try connecting to the Power Profiler app. When you select the device you should get a pop up window asking "Device must be programmed, do you want to proceed?" Here you should select Yes to flash the Power Profiler firmware onto the PPK. If you don't get this pop-up message, try doing an nrfjprog --eraseall while the PPK is mounted onto the DK

Also, please confirm that you've removed the jumper cable from P22 when you mount the PPK. I assume you have seen the PPK User Guide, but in case you haven't please give it a look as well, as it provides a detailed description of how you use the PPK.

What version of nRFConnect and the Power Profiler app do you have installed? You can also try updating the J-Link firmware on your computer.

Best regards,

Simon

Thank you very much for your help.

The issue turned out to be a faulty NRF52840 DK.
DK Looked good, correct LEDs and could be flashed, however it would error whenever connected the PPK.

Thanks again.
