Which kernel are you using?
uname -a
Try mainline kernel
sudo pacman -S linux
Or
sudo pacman -S linux-rc
I think we are facing the green screen issue again. Conflict with uboot and inverted rgb.
linux-vim have color issue since I moved to tobetters kernel source.
boot-vim3 is not script to boot over Android in emmc.
uboot-vim3 is uboot pkg, that is what will be present in your installation.
Plymouth is boot splash pkg which was recently added.
New images coming soon this week.
