You can also just upload the original file to some place where it can downloaded. That way there wouldnt be additional compression.

Looks like a new Linux driver for the Datapath Vision cards is out today: https://www.datapathsoftware.com/downloads/li … nstall-v7-28-0/.

Supports up to Ubuntu 24.04 with kernel 6.8. Somebody wanna give it a go? Lots of people were having trouble with the previous version that only supported up to kernel 5.

404 error.

They have a bad link. Try this: https://www.datapathsoftware.com/supportdownl … 8.0.7402.tar.gz

I'll see about making a 24.04 bootable Monday and test. Sadly, in Windows my card only receives a signal now for sync. I get just a black image instead of an actual image.

sweet, I'll see how it compiles, I've been off kernel 5 for so long I gave up on datapath updating the driver.

Kernel compiled fine on Ubuntu 24.04 and loaded so long as I had secure boot off (was testing on a live distro). Compiled the Vision program (VCS fails to compile, despite having all deps installed). Got an image, before the system hard-locked yet again. I wonder if just going back yet again to Windows 10 from a clean install would get this card working in Windows again?

VCS should build out of the box on Ubuntu 20.04. Needs GCC 9, newer ones have a problem or two.

Doesn't sound good for the card, but maybe it has a problem with DMA. VCS doesn't use it but Datapath's apps do. Could also be a problem with the video card in that case I guess, it's some kind of a Direct3D DMA thing that they use.

the datapath vision driver wont build for me. Im on 22.04, 6.5-lowlatency and I guess it has enough of a change from 6.8 to not be build-able out of the box. I'm going to see if I can build 6.8 mainline from source and see if it makes a difference.

I was trying to compile on 24.04

20.04 live image in a vm might be the way to go for compiling it, should only need the datapath header files and whatever qt/opencv dev stuff that isn't installed by default. If the binary compiled on 20.04 doesn't run on 24.04 then you could make an appimage of it. Otherwise if you're building on 24.04 make sure you have qt 5 and gcc 9, if no go then do it in 20.04.

I didn't use 20.04 at all. Only downloaded 24.04 to test the new driver.

As far as I know the stock 24.04 comes with qt 6, which is already not recommended for building it. Stick with qt 5 era stuff and you'll have a better time.

Huh, I did set up QT5. It was more the OpenCV4 stuff that caused the errors.

A few years ago I tested it against whatever version of OpenCV 4 comes with Ubuntu 22.04, worked. Without knowing what the errors are it's not possible to say anything more, but I recommend reporting the issue to the vcs repo.

New Ubuntu 24.04.01 install (6.8.0.41 Kernel), latest VisionInstall 7.28.0.7204 and its doesn't compile for me.

make[3]: *** No rule to make target '/home/deano/VisionInstall-7.28.0.7402/bin/rgb133.64.o', needed by '/home/deano/VisionInstall-7.28.0.7402/rgb133.o'. Stop.
make[2]: *** [/usr/src/linux-headers-6.8.0-41-generic/Makefile:1926: /home/deano/VisionInstall-7.28.0.7402] Error 2

Trying to figure it out. Suspect some dependency is missing

Just noticed that the compat matrix says 22.04 (6.8.0.36 Kernel). Maybe I'll try and find that exact version as technically my Ubuntu is slightly too new 😳

Curious, how did you try to build the driver?

Tried with both scripts/install.sh and make
All stop in the same place.
Tried with a self compiled 6.8.0 kernel and its the same.
Maybe I messed up the kernel header/source and/or the build environment.

Maybe a nuke from orbit and re-install just in case...

SUCCESS!!

Latest driver and vcs compiled and running on a modern linux distro!

I'll do a proper write up (and maybe a videos...) next weekend as it wasn't a straight route, so i want to do it again knowing what I know now.
