nRF9161-DK - VDD Setting in Board Configurator does not work

I noticed there's a new board controller firmware (1.1.0), I updated the DK and now it's working.

I also updated the Board Configurator application (0.3.0 --> 0.3.1) , but based on the short changelog it's unrelated to this.

HI, DanielDelgado and JyriLehtinen , we have been able to reproduce the issue and are working on a solation. Dont have a fix right now but you will be updated.

Regards,
Jonathan

No, still the same issue. I haven't looked into it after my previous reply.

Hi, any luck? I have the same problem. Changed to 3.3v in Board Configurator but VDD still ouputs 1.7V.

No difference, it is written to the board (I assume as it loads the previously written value after connecting the board) but no change in VOUT1 voltage.

2024.14

I'll test on another computer if the issue still persists, currently I've only tried one (and it's running Windows, I'll check with Linux next)

I have done some testing and am not able to reproduce the same behavior that you are seeing. TP21 or TP23 should be the correct place to probe. You should also be able to measure on one of the IO pins as well and see the VOUT1 voltage there since SB30 and 31 is shorted.

What is the number on the back of the kit? the sticker, should be year and week number.

Jonathan

Great, thanks for the updated documentation. Helps me find to which test points are connected to the VOUT1 and VOUT2.
However, the core problem still persists, the voltage settings are written to the board, but the VOUT1 and VOUT2 remain at the default values.

The schematic you show to is not the same as the image.

You have the version with the nPM1300, this should support setting the voltage in the board configurator app.

If you have a version with the two nPM1100 regulators then in the app it will look like this:

This is the schematic for version 1.0.0, can get it here now (recently updated): nRF9161 DK - Downloads - nordicsemi.com
