NRF9151 Failing Quick Start

[john_enganalysis]

Hello All, 

I am having an issue where attempting to follow the quick start for an nRF9151 development board leads to this error:

I have looked at this post, and unfortunately the logs do not apply to my situation. I have reinstalled Segger J-Link with the legacy drivers, and the onboard programmer is appearing within the J-link configurator app, as shown in the image below:

I have ensured that my firmware is up to date, and for the configuration I have ensured that the "USB Driver" is "Segger" and not "WIN-USB".

For my log files, this is what I see:

The full error was: Device error: Setting the debug port SELECT register failed while powering up sys and debug regions (Unknown error in the J-Link DLL (error code =-1)).

This might indicate that the debug port is unavailable. Double-check device power supply and SWD lines, and ensure that SWD is not disabled

Any help / guidance with this would be greatly appreciated - thanks!

EDIT: Please note that I have also tried the *tested* version extensively, but saw the same issue in the logs:

Hi John,

I believe the error you are seeing is most likely a USB driver or a faulty USB port issue.

Let's start with the basics, have you tried restarting your computer, plugging the device into another USB port ? If you are using a dock, can you try to connect it directly to your computer. Are you sure all your driver are up-to-date (USB, dock, maybe even BIOS).

Have you ever tried programming the DK in any other way than with the Quick start? If you didn't can you try building and programming the "Blinky" sample ? If you are not sure on how to do it, you can follow the first lesson of our DevAcademy (link).

Finally, If that still doesn't work, can you try to run the command "nrfutil device recover" in the nRF Connect Terminal.

Tell me if any of this worked.

Best regards,

Simon D-M

Hello - Thank you for the reply. 

I have tried restarting my computer and using a different USB port. I am using a dock, and so tried also to plug directly into the MoBo. The error log was different but the behaviour was the same. Here is the log:

I HAVE tried running the blinky sample, to which I am greeted by this error message:

Lastly, the recovery command also did not work:

I feel like the fact that it says "Unknown Device" in connected devices could be a hint? But at the same time, in the nRF connect app my board IS correctly identified:

Hi,

By any chance, have you removed the jumper that was on the "nRF current measurement" 4 pins connector (P22) right above the USB-C "debugger" connector ?

This connector is used to measure the current that the nRF9151 uses. So when not used, the jumper has to get back on to allow the current to reach the nRF9151. Otherwise, the debugger is powered but the nRF9151 is not, which can explain the fact that the board is recognized but cannot do anything.

The jumper has to be on the 2 upper pins "VDD_nRF" and "VDD_5V". It is also possible to "permanently" connect these by soldering the solder bridge (SB34) but I wouldn't recommend it because you don't really gain anything by soldering it instead of putting back the jumper.

Here is the documentation about this connector (link).

Best regards,

Simon D-M

Wow! I cannot believe I somehow missed this. There was even a jumper bouncing around loose in the box and I didnt see anywhere obvious for it. Thankyou very much for this!
