nRF52832 DK Programmer / USB?

[Andreas Schurz]

Hi,

I got a brand new nRF52832 DK today and wanted to program it but the USB is not recognized at all therefore the nRF Programmer shows no programming option.

I connected the board, switched it on while pressing the reset button. Programming LED is blinking and if I press Buttons 1 - 4 the relating LED shows up.

"nrfjprog --ids" is not showing anything at all.

Other devices such as "nRF52840 Dongle" and "Thingy:53" are working fine on the same PC.

Could you tell me what to do in order to fix this behaviour?

Many thanks in advance.

Regards, Andreas

Hi Andreas,

Please check if you have the Jlink legacy USB drivers installed as discussed in this post:  J-Link legacy USB driver required on Windows for some DK boards 

Neither the nRF52840 Dongle nor the Thingy:53 comes with an on-board Jlink debugger, so they are not affected by this.

Best regards,

Vidar

Hi Vidar,

I installed a later J-Link driver and checked the option as described. However: the nRF programmer 4.3.0 now is telling me:

Installed JLink version does not match the expected version (JLink_V7.94e)

Hi Andreas,

This is the version the nRF Programmer has been tested and verified against, but it should normally work fine with other versions as well. Is 'nrfjprog --ids' still not returning anything?

[Andreas Schurz]

Yes. Not returning anything. Also no USB detection going on. Just nothing.

Did also a reboot after driver installation.

Please try different USB cables and USB ports on your PC. The fact that the board powers on suggests that power delivery is fine, but there seems to be a problem with data communication.
