Green screen. Manjaro

how can I boot completely from sd and get rid of the green screen. I want to use mandjaro. When the green screen problem is completely resolved. Please detailed instructions, I just do not know English well and it’s hard for me to understand the firmware

You either need to use mainline u-boot or chainload mainline u-boot from the vendor u-boot; this is done via the boot autoscript files and a new (mainline) u-boot file.

PS: but chainload vendor uboot from mainline still works !

IMHO chainloading is not required on any Khadas board because mainline u-boot supports all of your boards. Just write an image with mainline u-boot direct to the eMMC, boot using a simple extlinux.conf and avoid all the autoscript and multi-boot complexity. If people want to run another distro … go write that image (with appopriate u-boot) to eMMC instead. I’m not entirely surprised things don’t work from vendor u-boot.

mainline uboot supported all boards but with many limits :wink:
for example spifc - like many other things not work

So what’s your plan to add spifc support to mainline u-boot?

yes ! i will try to do it soon

what other items are not working?

am getting Green screen on Manjaro, KDE Plasma
using latest Android PIE on the emmc

any workaround or just have to live with it

use the earliest version of Android on emmc and download from a cd card, take the image of Android 190809 from here:
