RE: nRF52833 Can't connect after erase all

Update:

I figured out that debug out connector P19 on the new PCA10056 (V3.0.0) was changed so that PIN3 is now the interface select pin and PIN5 is GND. I revised my cable and got some improvement. One board i was able connect and program. Two other boards are still not working.

Using "nrfjprog --recover" i get an error saying nrfjprog could not identify the target device. if I use --log I get: "[ nRFXX] - Device does not have an ARM debug port".

================================

Update of update:

Using a lower debugger clock (125KHz) I succeeded programing another board. So it appears to be a hardware problem on my boards after all.
