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?

Hi,

I got the same issue, but it gets to blinking mode arfter pressing reset button.
Check the manual here.

Indeed - there seems to be at least one per day on this public forum!

remember that the dongle is not the same as a DK! If you want to do a lot of development, buy a DK instead.

In light of the above, I think you should really make that clearer on the Dongle Product Page!

eg, see:

https://devzone.nordicsemi.com/f/nordic-q-a/39893/downloaded-the-sdk-for-the-nrf52840-and-found-out-that-all-refer-to-other-hardware-pca10040-and-pca10056/155417#155417

You could save yourselves a lot of work - and a lot of disappointed/frustrated customers!

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
