Hi Lars,

It is indeed concerning. I am discussing this internally with the team and will get back to you.

Hi Priyanka,

Yes, I experience the same thing with 2.9.0. Now I paste the contents from board.cmake in nRF52dk. It works fine with that version, but the original board.cmake in the feather-folder doesn't.

Hi Lars,

Apologies for the delay. Yes, I understand that the issue seems to be with the adafruit_feather file and thank you for pointing this out.

Could you please check if you have this issue in a later SDK version? say, the v2.9.0?

This could help us narrow down the issue.

Hi Priyanka,

Yes, it is that dts-file. Though, I run SDK 2.5.0.

I have now made my own board instead of using the Adafruit dts-file. I made a simple LED-blinking program, and it works fine. I followed your lesson on DevAcademy, and came across the file board.cmake. The one that was generated for my board is different from the one in the Adafruit folder. My board.cmake looks like this:

The one in the Adafruit folder looks like this:

So I just replaced this content with the content in my file. And now this also works. I know one shouldn’t adjust things in the SDK, I just did this for test purpose. But it feels strange that it is not possible to use the original file. Should one flash the board in another way than I do? Or why is it like this?

Best regards,

Lars

Hi Lars,

The error shows a J-Link issue. Could you check that your SEGGER J-Link is up-to-date?

Also, what version of the nRF52840DK are you working on?

Is this the dts file that you are not able to flash?

Regards,

Priyanka
