Programming issue dll ERROR NRFConnect Programmer

[Olfox]

Hi,

I still have issue with programming.

I don't understand why i always have trouble with DLL.

I'm able to program with SES, the bootloader and my application. But i also need to flash the softdevice and settings page. Usually i do it by using NrfConnect / Programmer.

But here it doesn't work any more.

It looks somthing related to the jlink i'm using, it is already up to date ( v6.82c). and driver are : 

>nrfjprog --version
nrfjprog version: 10.8.0
JLinkARM.dll version: 6.82c

I'm supplying the DUT with 3.3V, 800mA output current regulator.

Jlink and my production board have gnd in common. I have disconnected the vdd of the jlink because i didn't trust it as it was 3.1V ( it seems to not be an official Jlink programmer).

What is strange is that with SES i have no issue to program.

Thank you

I succed also in programming my 4 .hex with nrfjprog command line, so i have doubt with nrfConnect/Programmer software.

I also need to regenerate each time setting page after modifying and build my app. I guess it is linked to a crc checked or another checked in bootloader ?

should i enable NRF_BL_APP_CRC_CHECK_SKIPPED_ON_GPREGRET2, NRF_BL_APP_CRC_CHECK_SKIPPED_ON_SYSTEMOFF_RESET or NRF_BL_APP_SIGNATURE_CHECK_REQUIRED ?

Thank you

Hi Florian

In the latest nRFConnect updatest there have been a few compatibility issues with the nrfjprog version used alongside nRFConnect for Desktop, so there's likely an issue with the nrfjprog version you're using alongside nRFConnect. Try updating to a more recent version. The latest version should support nRFConnect v3.6.1,  but I see you're using v3.6.0, so you can try downloading nrfjprog v10.11.1 if you don't want to update your nRFConnect version.

Best regads,

Simon

Hi

Can you provide some more details about this J-Link device you're using? If it's not an "official" programmer as you say, that might be the reason it doesn't work with nRFConnect. Do you have a Development Kit available to test if nRFConnect works when using a DK? That should confirm whether the issue is with nRFConnect or the J-Link programmer/ the custom board.

Can you also try doing an nrfjprog --eraseall on your custom board to check if "emptying" it makes any difference?

Best regards,

Simon
