OS: Windows 10
NCS: 2.0.0
I am working on the Nordic DFU NCS Guide on a nRF52833 DK devzone.nordicsemi.com/.../ncs-dfu
After flashing/debugging several times, I started seeing the message below. I responded with "yes". Now I am not able to "debug". I can only "flash" it.
I thought something was wrong with the board, so I used a brand new nRF52833DK. The same thing started happening.
Any idea of what is going on?
Hi Garvit,
Thank you for providing required information.
I am not able to reproduce your issue.
Have you tried to recover your boards before flashing?
Best regards,
Dejan
I have a similar issue.
I am working with an nRF5340 DK (PCA10095 - 2.0.0 - 2022.4).
I have to use "nrfjprog --recover" every 2nd time. In other words, it fails the first flash, then after the recover, it usually flashes successfully, once. Then next time it will fail.
And trying to use Debug is almost impossible.
Hi garrettb ,
Could you provide all required steps for reproducing the issue?
Best regards,
Dejan
Hi Dejan,
Here is what I did just now:
My setup:
VS Code: 1.85.2 (user setup).
nRF Connect for VS Code: v2023.11.301.
NCS: 2.4.1.
Set up steps
Create new applicaiton.
Copy sample: nrf/samples/bluetooth/peripheral uart.
Add to workspace.
Build configuration: nrf5340dk_nrf5340_cpuapp_ns:
Connect nRF5340 DK board.

I repeated these steps - and it failed every second time, etc.
At one stage, I was prompted to recover the device and reflash.
If I select Yes - the flash succeeds but fails next time.
However, if I select "Always in this session", then it succeeds for the next three flashes (I didn't try any more).
However, when I then select Debug, instead of Flash, it fails again:
