Can´t flash softdevice with nrf connect for desktop

[simon1516]

Hi,

im trying to flash a 3rd party demo board (MDBT50Q-512K Module Demo Board) with nrf connect for desktop. As programmer I use original Segger j-link edu mini.

As you can see on the following image, I can´t "Erase" and/or "write" the softdevice 140 to the board.

I´ve installed the actual software of:

nRF5 Connect For Desktop

nrRF5 Command Line Tools

nRF5 SDK

Do you have any idea what I can do?

Thanks in advance

Simon

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,

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.
