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

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
