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,

Michal

[allard.p]

I removed my version of NRFJPROG and installed v10.23.0. This version comes with jlink driver 7.88j, same problems. I assume NRF connect for VScode takes the NRFJPROG version installed under "C:\Program Files\Nordic Semiconductor\nrf-command-line-tools" ?

[Michal]

Did you try upgrating the OB JLink firmware using Segger tools?

Best regards,

Michal

[allard.p]

Firmware is up to date:

SEGGER J-Link Configuration V7.88j
Logging started @ 2023-08-21 15:47
Updating firmware of probe/ programmer 1 of 1 via USB (SN: 6001xxxx)...Not updated, probe/ programmer firmware is already up to date.

[Michal]

Thank you for checking.

How are you connecting the DK by the way? Are you connecting the USB directly to your PC, or via a hub?

There is no COM port connected to the DK when trying to flash for the first time, right?

Best regards,

Michal

[allard.p]

Not sure what you mean with 'DK', but if it is the debug probe, this is connected directly to the PC, no hubs.

I've two situations with programming troubles:

- The testboard situation, where the DUT is tested and programmed, here is also a USB<->UART connected. In this case NRFJPROG is called from my test software. In this case every second try succeeds.

- Programming in development from VSCode. In this case programming always fails, only full erase works, not '--sectorerase'.

I also tested without USB<->UART connected, no change. When i change the debug probe from a JLink plus to a Jlink base the error message in VSCode changes slightly.

This is with the plus version:

-- west flash: using runner nrfjprog
-- runners.nrfjprog: Flashing file: D:\[PATH]\merged.hex

FATAL ERROR: command exited with status 33: nrfjprog --program 'D:\[path]\merged.hex' --sectorerase --verify -f NRF91 --snr [serial]

And with the base version:

-- west flash: using runner nrfjprog
-- runners.nrfjprog: Flashing file: D:\[path]\merged.hex
[error] [ Client] - Encountered error -102: Command erase_file executed for 217 milliseconds with result -102

FATAL ERROR: command exited with status 33: nrfjprog --program 'D:\[PATH]\merged.hex' --sectorerase --verify -f NRF91 --snr [serial]

With the plus version I am able to execute a sector erase in J-Flash without problems.
