Hello,
I have a BBB with a 4D Sytems display. Used to work well with older Debian versions. Now I have the 2020-04-06 version and I can not make the display work. I tried to modify uEnv.txt from what I know and saw on internet.

Above is the version.sh result.
Please advise.
In the meantime I found Debian version 2019-08-03 with LXQT. Now the display does not work at all. Not even in text mode. I can resend the version.sh if desired. Please advise. Many thanks in advance,
Hi @yrrah53 grab a newer snapshot:
I’m pretty sure in 2020-04-06 the pwm udev rule stole the pwm backlight from the 4D’s display…
Regards,
I’d love to do that but somehow it does not work… New in this community.
Hi @yrrah53 what does not work with the latest testing images?
Regards,
here it is…

HI @yrrah53 ,
Do you have a hard requirement to use 2020-04-06 or 2019-08-03 ???

Thanks for your fast response Robert. Not at all. I will try Debian 11.
Robert,I have installed Debian Image 2022-07-01. It works but not for the 4D Systems display. Also: the directory structure has changed so I do not know how to get acces to version.sh.
It’s:
debian@BeagleBone:~$ sudo beagle-version
Since you probally used the microSD and not the flasher also run:
sudo /opt/u-boot/bb-u-boot-am335x-evm/install.sh
sudo reboot
Regards,
Ok, so I did. the display works now in char mode. sudo beagle-version gives very little info… via Lan connection…
Sorry Robert, I selected the wrong version. Now I have the LXQT version fully running. I will continue tomorrow. So far: thanks a lot for your help.
Hello Robert, My findings so far. Display worked, only once. After reboot no display at all. Working remote with Putty. Guess you will have some magic command to make it work… It seems the directory structure has changed? Sudo beagle-version does not work here. I have not touched uEnv.txt yet. It seems the directory structure has changed? What really worries me is the message: Errno 28: No space left on device…
Are you running the 2GB or 4GB eMMC? The desktop’s really don’t fit in the eMMC now days… It would be best to just run it from the microSD card…
Regards,
Running 4 G version. I need LXQT and two serial ports and some IO bits. Can I delete something I do not need or do I need a bigger uSD card? I also need some (large?) Python libraries. How do I run from a card? What size do you recommend?
