Same problem here. After selecting a programmed BLE device the screen turns white.

Thanks, but I already tried that. I should of course have mentioned that.

I'm also using Ubuntu 22.04 and have the same white screen problem. When I downgraded libstdc++ to 6.0.28 I couldn't boot my laptop anymore. I managed to fix that by reinstalling the original version in recovery mode. In case you don't want to spend some hours on recovery I don't recommend downgrading libstdc++. My white screen problem remains so if anyone has another advice it would be appreciated.

RE: nrf connect desktop app blank screen

fanoush — Sat, 18 Nov 2023 21:32:18 GMT

what worked for me without downgrading libstdc++ was to run it from terminal with preloading system libstdc++ version via LD_PRELOAD like this

LD_PRELOAD=/lib/x86_64-linux-gnu/libstdc++.so.6 ~/opt/nrfconnect-bluetooth-low-energy/nrfconnect-bluetooth-low-energy-4.0.4-x86_64.AppImage

my guess is that the AppImage contains older version of libstdc++ and having both in memory may cause this so by preloading system version there is only one loaded

Hi,

I don't have access to a Linux desktop today I can't verify this fix on my end. however I heard from a coworker that downgrading it by a tag worked from him, so https://ubuntu.pkgs.org/22.04/ubuntu-main-arm64/libstdc++6_12-20220319-1ubuntu1_arm64.deb.html this version can be worth trying

Thanks for the quick response, would be great if you could specify which libstdc++ version to downgrade to. This was also asked for in the solution post you provided here, but no further info there.

BR,

Aleks

The best suggest I can provide is to downgrade libstdc++ to an older tag. The developers has identified the cause of the issue however it does not look like there will be any way to fix it in the near future which does not require downgrading libstc++

I would recommend trying the solution posted here,

I have the same problem ,with the white-screen suddenly popping up after at least one year of usage on Ubuntu 22.04.3 LTS and this is the output I get from the nRF Connect BLE application:

10:33:01.092 Using JLink version: JLink_V7.80c

10:33:01.121 Installed JLink version does not match the provided version (V7.66a)

So the application starts and it is possible to select the nRF connect device in the device drop-down list, but get a white-screen as soon as this is chosen. In my dmesg I can see this:

[ 1811.420595] nrfconnect-blue[5370]: segfault at 0 ip 00007fdebf28842b sp 00007fdeb99faba8 error 4 in libstdc++.so.6.0.30[7fdebf250000+111000]

So it still feels kind of related to the libstdc++ version. Any new suggestions?

Aleks

Hi,

The supported version with the app should be

JLink_V7.66a. The developer has also tested with JLink_V7.80c. Can you try if this works for you?

Thanks

Could you try to open the app an then disconnect and reconnect the device and then select it and post the logs?

just after selecting the device

Thanks, do the blank screen happen just after selecting device, or does it happen before?

That's what im able to collect with a copy paste. After 2 seconds the blank screen appears:

At some point i was able to get also the following log, but in that case no blank screen appeared, but application still did not go through.

Thanks for the update.

Are you able to run BLE app with verbose logging on and share the log? You will find the option in the about tab in the BLE app

hi,

number 2 i found the solution on forum (port flag should be explicitly given, snr is not enough):

nrfutil dfu ble -pkg dfu_edh_0.11.4_for_testing_purpose.zip -ic NRF52 -n DfuMTK -p /dev/ttyACM0 -f

Problem 1 still persists.

RE: nrf connect desktop app blank screen

runsiv — Mon, 21 Aug 2023 10:57:05 GMT

Hi,

I have asked the developers regarding question 1

Regarding question 2. Do you have https://github.com/NordicSemiconductor/nrf-udev installed?

According to one solution libstdc++.so.6.0.30 has to be used. I already have this version on my system. And it doesnt work.
