In addition to the moral/ethical arguments about open-source vs closed source, there’s the practical concern about the possibility of community support when/if Khadas decides it’s not financially worthwile to continue VIM4 support in OOWOW after VIM5 comes out.
Hi, where can I find the sources for the latest oowow. We’ve had some issues with a machine vision camera we are using when upgrading to the latest oowow, and rolling back to a much older version seemed to have fixed it. It would be great to know where I can see the sources for the various builds of dl.khadas.com - Index of /products/edge2/firmware/oowow/versions/edge2/ - it would be great so I can bisect it myself and see what might be the cause of our issue.
We use the Khadas Edge 2 on Ubuntu 24.04. Updating the spi image changes something such that the usb camera cannot acquire frames at full rate, and drops out. I have toggled back and forth between the latest edge2-oowow-250801.000-spi.img.gz and the working version that was on the board edge2-oowow-230308.000-spi.img.gz
Nothing else changes on the board apart from flashing this image, and it goes from being unable to aquire to working fine. The camera is a machine vision USB camera from Ximea.
Their software performs a bandwidth measurement on start of acquisition. With the new spi image, usb bandwidth is measured at various low numbers around 700mb/s to 1100mb/s, and there are lots of usb errors.
With the old image, it works.
I realise this is quite a large gap between versions, so may be hard to isolate what could be the cause. I was planning to bisect it down to the image where the problem first occurred, but without any source code, or information, I wont be able to find anything out.
Thanks for the information. I would be good to resolve it with oowow, instead of wiping the spi - as for us oowow is one of the reasons to use an edge2 for this soc vs an orange pi 5.
