JLinkARM.dll reported "-1", an unknown error

[Nicolas Goualard]

Hi,

I am trying to erase and flash a nRF52840 chip on a custom board. I use a J-Link EDUwith the Cortex M adapter to plug onto the board. I checked the hardware conf several times, it looks fine to me.

I am running Linux Mint 20.3 on Windows VirtualBox.

Running nrfjprog -v delivers the following:
nrfjprog version: 10.15.2 external
JLinkARM.dll version: 7.60e

I attached the corresponding log.log file. Do you have an idea where the problem might be ?

Thanks in advance for your help.
Best regards,
Nicolas G.

Hi Nicolas,

Have some questions regarding the setup. 

Have you been able to program\erase other nRF products with this setup before? 

Is the custom board powered?

Have you made sure you are not mixing up the CLK and IO line?

Does the nRF52840 have readback protection enabled, have you tested the recover command?

Regards,
Jonathan

[Nicolas Goualard]

Hi,

First of all, thanks for your fast reply.

It's the first time I try erasing/programming nRF products. I am taking over someone who has worked on this product before and was able to do it using this setup (however they were working on a MacOS machine). This person has left the company before I arrived though, so I can't ask too much help that way. But because of this I am pretty confident in the hardware I am using.

The board is powered.

I don't know about readback protection. When I send nrfjprog --recover --log the same problem arises. I attach the logs for this command.
