RE: Upload on nrf52_dk Cannot connect to target

ClementKZ — Tue, 04 May 2021 13:44:00 GMT

It seems like I solved the issue by putting a cable like the picture below to short circuit nrf measurement.
Someone used the board before me and didn't told me that the cable was needed.

Thanks for your help Einar

As you said we can see on the picture that SB9 has been cut. It didn't check it.
Any idea why SB9 would be cut ?

I found answer to my own question, the SB9 has been cut to do power measurement.

Hi,

It seems like the onboard debugger is not able to communicate with the nRF. Is this a new DK, a DK you use it successfully before or did you "inherit" a DK from someone else? If the latter, could it be that the SB9 solder bridge has been cut so that the nRF is not powered? If so, you need to put a jumper on the nRF current measurement port.

I try to use nRFprogrammer instead of platformio and I got a new error.
My error being :

ERROR Could not fetch memory size of target devkit: Error: Error occured when get library info. Errorcode: CouldNotOpenDevice (0x4)
Lowlevel error: JLINKARM_DLL_ERROR (ffffff9a)
