Great to hear you solved it!

Ok, now it works. I run "sudo JLinkExe -device nrf52 -if swd -speed 4000" to update the firmware and after that the flashing works OK.

That recover did get stuck just like regular flashing with the 9.0.0 tools. I tried flashing also, but it also stuck like before.

Markings in the chip: N52832 QFAAB0 1606AA With working sample the last part is 1612AP

You may need a nrfjprog --recover -f nrf52 as the board may have entered a weird state after the failed flash attempts. I will try to get hold of a board here to try to reproduce. What are the markings on the nRF52 IC on your board? (The nRF52 is located inside the painted rectangle above the four buttons. Should be nRF52832 something something.)

Also, it may be worth downloading and installing the latest J-Link Software and Documentation Pack from Segger.

Can you try with the latest version of nrfjprog (part of nRF5x-Command-Line-Tools-Linux32 or 64 found on the nRF52 DK downloads page.) There has been some relevant bugfixes lately.

Uh, and please ignore the old SDK0.9.2 folder in the path. I originally started with that SDK and workarea just stuck to that folder. We are using nRF5_SDK_11.0.0_89a8197.

And as I said, I can flash both samples of my older 2016.9 -version just fine. I've now tried 3 boards from the 2016.21 and none of them seem to work with nrfjprog.

Same thing with softdevice and application flash.

Unfortunately I have linux only system here and we do not have Keil setup either.

What version of nrfjprog are you using?
What OS and version are you using?
How far do the programming go, i.e. what output do you get from nrfjprog?
Can you try programming the board from nRFgo Studio and/or Keil as well?
