nRF connect for desktop BLE & DTM apps opens with a blank window

[eyalasko]

Hi,

Like many posts before I'm facing blank white screen when trying to run nRFCOnnect for desktop (3.4.1) BLE app (2.4.0)

Tried to:

• Restart PC
• Uninstall-reinstall 3.4.1
• Uninstall-reinstall 3.4.0
• Uninstall-install latest nrf command line tools-reinstall (link)
• Use nRF52840 (PCA10056) dongle
• Use nRF52832 (PCA10031) dongle
• Use another fresh nRF52840 dongle

all to no avail....

Same blank screen occurs on all other NRFConnect's apps: DTM, RSSI viewer, Programmer but NOT with the toolchain manager... implying it stems from (probably) the same root cause (jlink driver? graphic library?)

Any advise ?

I was not able to do it that way, since the earlier version libstdc++6=12.1.0-1ubuntu1~22.04 seems not to be available any more on the update server (but only 12.3.0, with which the conflict seems to occur). I still got an earlier version for my distro and architecture. I placed the file in  /usr/lib  and re-linked  libstdc++.so.6  to that file.

That was my quick workaround - mainly to prove that my problem has to do with libstdc++6 12.3.0. It is certainly not recommended, also for security reasons!

Hi Jakob, can you elaborate on how you got the older libstdc++6 from http://archive.ubuntu.com/.

Allso how you re-linked it ?

Thanks for the hint, Runar

I can confirm to have nrf-command-line-tools_10.23.0_amd64.deb installed

Hi scottesimon,

[assuming you are on Ubuntu 22.04 64bit] download libstdc++6_12-20220319-1ubuntu1_amd64.deb and extract libstdc++.so.6.0.30

rename the file and (sudo-)copy it to the location of your cuerent libstdc++.so.6.0.30, probably /usr/lib/x86_64-linux-gnu

rewrite the link from libstdc++.so.6 to your renamed file, e.g. sudo ln -fs <your_renamed_file> ./libstdc++.so.6

check if your nRF Connect for Desktop App is working (and revert the link change afterwards).

Regards,

Thank you so much Jakob. With your help, I was able to get it working again !!
