I had a similar problem, and tracked it down to nrfjprog options.

Based on the details you've provided, it seems that the issue might be related to how memory is being managed and accessed in your firmware, especially if the problem arises after the first flash when using the nrfjprog tool. The fact that erasing and flashing works, as well as unplugging and re-plugging the USB cable, suggests that something in the state of the flash memory or the nRF5340's firmware state is causing the problem.

When APPROTECT is enabled then device would need to be recovered before you are able to write to it again.

It seems like the situation is a little different based on what I gathered from its support case. It's not that I can't work; it's just that I keep making the same mistakes. The write fails and the -nrfjprog error message appears if I do not erase it.

Sorry Jonathan, i totally missed your message!

No, i have no APPROTECT enabled. As a confirm of it, if i try to add:

CONFIG_NRF_APPROTECT_LOCK=y

in my proj.conf file i get the comment "in build: n"

frax84 , does the firmware you flash have APPROTECT enabled or disabled?

Not sure if we have any public issue reports that you can follow, but I have asked if this is something we can provide.

Hi Jonathan,

any news on this issue? Is there an issue report on github we can follow?

So, in summary:

If nrfjprog --program includes --sectorerase it may work if you time the operation to start after a reset just right. It seems like there could be something fixable in the nrfjprog DLL, or it might be in the underlying JLink software. The problem is reproducible with the JLink OB and JLink Base debuggers and on mac/PC and with NCS 1.7 thru 2.3.0.
One could just always do a "flash then erase" operation, but this clears UICR.OTP, which we use for immutable device lifetime information that has to survive a firmware upgrade, so it's a nuisance to have to re-program that data with a user-flash-erase either in the Terminal, outside of VS Code, or binding a shell script to one of the two flash buttons.

I think we''re experiencing the same problem. It may be related to how CTRL-AP is implemented in the nRF53 & nRF91 series. --sectorerase can usually be made to work after a reset and occasionally only after recycling power. JLink produces various errors and that's a clue that the cause of this longstanding issue may be at the intersection of secure flash protection / nrfjprog / JlinkExe.

Jonathan, could the folks who did the nrfjprog DLL reproduce this problem?

No, actually from what i understood following its support case the situation is a bit different. It's not that i am not able to work, it's just that i have to write and erase everytime. If i don't erase, write failes and i get -nrfjprog error

Where you able to solve wit the details provided in paul.landers reply?

I had a similar problem, and tracked it down to nrfjprog options, as detailed in this support case.
