I’ve just recently faced a weird issue after updating old vendor uboot to new mainline (khadas-patched, I presume) version via Kresque. I’ve tried both
Khadas.UBOOT.mainline.emmc.kresq and VIMx.UBOOT.mainline.emmc.kresq, effect is the same.
In two words: the HDMI output seems to be glitching. I see a double green line on the left border of the screen and some colors are fuzzy (doubling?). Also, in graphics mode X11, the screen randomly blinks once in a while, may be every 2-3 minutes or so. That was not the case with the old uboot but it was working with the 4.9.x android kernel, and everything was perfect. I also tried 5.7 and 5.9 versions of the kernel and all is the same. I’m attaching a photo from the screen showing the color issue, it’s from the plain linux console, but in X11 it’s the same. I was hoping may be somebody has already found out what is the root cause of the issue and could help me solve it.
Thanks in advance.
