nrfjprog failures

[allard.p]

I'm working on custom test software for use in production programming/testing of my product containing a nRF9160. I'm using the nrfjprog executable, but with problems, every second call to nrfjprog --program is failing:

I checked my application, I do not set APPROTECT anywhere. The --recover works, but triggers a full flash erase (?), i do not want this, because it erases all my settings etc.

I also have the problem with programming from VSCode. Program + erase always works. Program with --sectorerase does not work, the same 'unknown error (-102)'.  The error occurs after 'erasing sector 2':

[ #############        ]   0.259s | Erasing non-volatile memory - block 2 of 2   

The erase of block1 succeeded,  so i do not think the problem is with APPROTECT. I'm also able to connect with J-LINK commander, so the debug port is working.

I did not have these errors in the past, but I do not known what caused the errors to happen.

Hello again,

Could you try upgrading your JLink driver? It may have gotten fixed around 7.82.

Best regards,

HI Michal 

 Is there any new from this issue?

I've got the same kind of issue with the last nrf command line tools release (nrf-command-line-tools_10.24.2_amd64.deb) on Linux. This package is bundled with JLink_Linux_V794e_x86_64.

best 

[Michal]

No update I'm afraid.

Are you able to use the 10.18.1 version instead?

[joel-sc]

Yes 10.18.1 works.

Would it be possible to know what is the issue ?

[Michal]

I am trying to find out internally about it.

[Michal]

Could you make a new ticket with the information about your setup for a proper follow-up?

Best regards,

Michal

[joel-sc]

I'll do it as soon I rework on this issue.
