JlinkARM.dll returns '-1' repeatedly, using nRF52840 on a custom development board

[mrc2022]

Hi,

We've been in the process of debugging our development board but are having issues. When we try to connect to our board we get:

ERROR: [SeggerBackend] - JLinkARM.dll reported "-1", "An unknown error.".

We are using the VS Code extensions for flashing, this is the terminal:

So I ran the same command it errors on through a CMD on Windows

Here is the provided log when attempting to run "nrfjprog --program 'zephyr.hex' --sectoranduicrerase -f NRF52 --snr 801029963"

Hi MRC,

It could look like the nRF52840 on your custom board can not be reached by the programmer.

I suggest first checking that the nRF52840 is powered.

Then double-check if the nRF52840 has contact with your programmer.

Could you explain how you have connected your custom board to the programmer?

Regards,
Sigurd Hellesvik
