Ah I see. Then I am sure you'll get the help you need there.

Good luck with VSC, and I hope you'll have a great day!

Thanks! I opened up a new ticket here for the debugging issue: (3) nRF5340 network cpu debugging - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

In general it's working, just not for the network CPU. I also get to see said window, but immediately halted somewhere in the disassembly.

However, debugging is not working :/ The joy of unknown IDEs.

Hehe I hear you. It is quite easy to learn though, and great to use when you do. Is nothing happening when you press the Debug option? Are you seeing these icons on top of the VSC window?

I see. I could probably help you with this json problem as well if you would provide me with a bit more info, though I agree that transitioning to VS is a good choice as well.

Hi Elfving,

thank you! I went for a SES reinstall, and am running into a JSON whatever problem right at start now. Seeing SES is being outphased, I'm trying to transition to VS now; flashing the board is no issue with VS, so that is good.

However, debugging is not working :/ The joy of unknown IDEs.

Uli

Hello Ulrich,

I will have to get back to you next week.

Though I believe you are running into the readback protection, that is enabling itself again by default after something is flashed to the DK.

So having to recover the chip, or erasing all is what is expected. You can continue doing this if you want to, or if you find it cumbersome you can disable it.

Regards,

Elfving

nrfjprog --version is sometimes requested, that is:
