nRF52840 Dongle

[JamesBellville]

I have a new nRF52840 Dongle which seems to have either had a hardware failure while updating its bootloader or the updating was unsuccessful and now the device does not flash the red led, what can I do to update the bootloader or test the hardware?

[JamesBellville]

would I be able to program the nRF52840 Thingy using Segger and DK, I have not checked yet but did find the problem encountered above trying to program via the USB

[JamesBellville]

apparently it has the same issue, now to get a programmer for the two Nordic units I have

Thanks for that awneil, I will mention this internally.

Are you referring to the Thingy:52 or the 52840 dongle when you write 52840 Thingy? If you want to program the 52832 Thingy:52, you can either use DFU via the Thingy app (iOS or Android) or via the debug out port on the DK & a SWD cable. The documentation here could also be helpful.
