Hi,

SEGGER J-link is what we officially support,

Yes, but I would like to find a way to flash my boards without usign the nRF5DKs.

Hi,

I will continue to help here.

[quote user="Thibaud"]Is there any JTAG probe so I can replace the nrf52dk with ?[/quote]

I do not understand the question. Can you elaborate a bit?

You can use an external debugger to program the nRF52DK.
You can use another of your nRF52DKs and connect their Debug Out to the other ones Debug In.

This is a good way to figure out if the nRF chip still works or if the issue is related to the debugger chip.

Yes I get the same arrors when I reset it and no I haven't shorted or used any of the other switches.

Is there any JTAG probe so I can replace the nrf52dk with ?

You haven't shorted anything or used any of the other switches on it? Are you getting similar errors when just resetting it? (ie. nrfjprog -r)

Although, could you advise my any jlink solution to flash a NRF52833 because for now I am using a nRF52833dk but I would like to develop my own flashing solution.

You could look into getting something like a JLink Commander, though that can be a bit more expensive.

Hello,

I already tried all of this.

As I said, I can flash an other nRF52 with my board so I don't think the problem is coming from the interface MCU.

Although, could you advise my any jlink solution to flash a NRF52833 because for now I am using a nRF52833dk but I would like to develop my own flashing solution.

Yes, it did work, SW9 is set to VDD and SW6 to default.

Hello,

Please have a look at the steps mentioned here.

Regards,

Elfving

EDIT: Are you saying that it did work earlier? Is SW9 set to VDD and SW6 set to Default?
