I looked over the git page and did not see what I needed to see. So, it appears they are not open sourcing the entire build process. They have an image for the Pi so they are close. All you can do is try. Pretty sure the PI4 build will not boot on the VIM3.
This would be the first time for me to do this. So how would I ‘rip the rootfs’ from a new build that I make? Is there a manual for this? It would be my first time. I’m not an expert.
@haste you can mount the rpi disk image and copy the contents of files and other components of the image into your own new image and with the required uboot, dtb, kernel, and flash the image to the vim3.
I will look into this over next week to provide some solution regarding this for you.
Hello @haste, I have taken a look at the start-os project but it does not provide any way to create generic arm64 image, they only provide installer iso and rpi image which may not be suitable for VIM3.
Do you know if they provide generic arm64 img file ?
