Is it possible to program the nRF52840 dongle using the nRF52832-DK using SWD?

Hi Tommy,

Please take a look at this tutorial if you haven't already: https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/nrf52840-dongle-programming-tutorial. It's fine to re-program the dongle via the SWD interface, but as mentioned in the tutorial, be careful to not erase Non-volatile regulator setting.

I guess the orange cable was used to short the current measurement header because that particular board had the SB40 solderbridge cut (Cutting solder bridge for current measurements)

Hi:
I try to do the similar things.
May I know what is the orange line used for?
In above setting, will the DK also be programmed while program the dongle?

Thanks,
Tommy

Hi.

There shouldn't be any difference, it should also work, did you try what I proposed?

I tried using the SWD pins instead of the P1 connector and connecting both GND

But it hasn't worked so far.

Hi.

Yes, but it is really important that the voltage on the nRF52840 Dongle matches the nRF52832 DK.

The safest way would be for you to solder a ARM Cortex JTAG SWD 10pin Connector onto footprint P1.

Like this:

And then use a 10-pin 2x5 1.27 mm pitch cable, like this one, to connect the nRF52840 Dongle to the nRF52832 DK

Like this:

Then you simply put the USB into a USB-port, like this:

You should then be able to program the Dongle from the nRF52832 DK. More information can be found here.

I am not using that DK, instead, I am using the nRF52832 DK. Is it possible to program the nRF52840-dongle with the nRF52832-DK?

Hi.

Have you tried to recover the nRF52840 DK and Dongle?

Try: nrfjprog.exe --recover --log

This will create a log file located in the folder you run the cmd from.
