Can´t flash softdevice with nrf connect for desktop

Hi,

That may mean that the target board runs on a lower voltage than what the J-Link programmer can program. For instance, the programmer on our development kits only program boards running on 3V. I see that the J-Link EDU Mini specification states 3.3V for target interface voltage.

What VDD is the module using, and is it powered?

Terje

Hi,

nrfjprog is a command line tool, which means it is run from a terminal. That means you should open a cmd window, and from the terminal prompt you issue the commands. E.g. write "nrfjprog --eraseall" (without the quotation marks) then press enter. The command "nrfjprog" (with no options afterwards) will list the available options.

You will get messages back on the command line, and if anything goes wrong then the error messages are of great help for figuring out what might be the issue.

Hi,

unfortunaly I can´t work with "nrfjprog". It seems, that this tool doesn´t work for me. When I start the program per doubleclick I can see a short time a cmd window, but it closed after a few milliseconds automatically...Do you have any idea, fixing this?

Hi,

Can you try with nrfjprog instead? E.g. "nrfjprog --eraseall" for erasing.

when I switch to the demo board, the LED in nRFConnect lights green. When I switch to J-Link, the LED is grey..

Hi,

I´ve updated the J-Link. Now, the Firmwarte is actual, as seen below.

Unfortunaly, in nRF connect, the error still exists. Does the LED on the top, next to the programmer name has to light green? This is not the case.

Thanks in advance,

Simon

Hi,

Can you check the firmware version for the firmware of the J-Link Edu, through use of "J-Link Configurator" (distributed with J-Link Software and Documentation Pack) and if old upgrade to the newest version?
