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,

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?

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

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

Hi,

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

okay, I tried it, but an error occurred. I attached this error by screenshot.

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?
