Hello, since this morning I have been able to program my device sucessfully. This morning I get prompted to upgrade to nRF Connect to 4.0.
Since then, I am no longer able to program my device. To be complete, this is a new board (and I do not have an old one for a backward checking).
The error I get using the programmer (v3.0.7) invoked from nRF connect is:
11:57:16.657 Device version NRF9160_xxAA_REV2

Then, after looking at the following thread: nRF9160's getting bricked?
I tried the command line
in\nrfjprog.exe" --program .\nordic_1.3.1.hex --chiperase --verify --reset --log

Looking at the log file, it *seems* that the programmer does access the device successfully though
I the tried Segger J-Flash Lite which ends with an, error too "could not download file"
I went through multiple remove/install of tools (segger and nordic ones) with no succes.
Anny suggestions on what could go wrong ? Can it be a device issue (I mean the nrf9160) itself though the device seems responding.
Thanks
Pascal
