<Armbian-Discord> <l​anefu> I wonder if board family is mandatory these days. Too much stuff in the common includes
<Armbian-Discord> <c​0rnelius> i would just call it rk356x. there is an openwrt github that appears to have working mainline uboot with a mix of rkbins. unfortunately I don't have nay of these boards and my current testing of it has only been with the nanopir5s. testing is from across the pond, so I don't have the board in front of me, which makes it very limiting. there is uboot and kernel patches for some rk356x stuff here:
<Armbian-Discord> <J​ohnny_Mucambo> Hello everyone. Does anybody can help me with HDMI on rockchip? i have orangepi 4 and i'm trying to get image in a LCD 7'' monitor over hdmi but the image is with offset.
<Armbian-Discord> <J​ohnny_Mucambo> running Armbian 22.05.3 with bleeding edge Linux 5.18.0-rockchip64
<Armbian-Discord> <J​ohnny_Mucambo> i tryedto implement new args in armbianEnv but it doesnt work
<Armbian-Discord> <J​ohnny_Mucambo> i tryed to edit boot.cmd and compile and it didn't work as well so... do you know other way? Kernel mode setting is it possible?
<Armbian-Discord> <J​ohnny_Mucambo> The LCD is https://www.farnell.com/datasheets/3435591.pdf
<Armbian-Discord> <J​ohnny_Mucambo> cannot read edid and if i connect LCD to my computer it works very well... With a raspberry pi too but with oranges pi with armbian H5 or rockchip SOC won't work ... whene i tryed with Jammy i had no image at all but with Sid version show some image but with offset and bad quality.
<Armbian-Discord> <J​ohnny_Mucambo> could you give me some tips... I'm lost
<Armbian-Discord> <J​ohnny_Mucambo> sorry, wrong image
<Armbian-Discord> <K​ropotkin> I happen to be facing a simillar problem
<Armbian-Discord> <K​ropotkin> is it possible to generate a modeline using CVT and force that mode when booting the system ?
<Armbian-Discord> <K​ropotkin> or do i need to patch u-boot to force a resolution
<Armbian-Discord> <K​ropotkin> ?
<Armbian-Discord> <l​anefu> You can use the Linux kernel video= argument to brute force settings for your device
<Armbian-Discord> <l​anefu> It's fiddly to find. Also yeah the DRM driver doesn't have some resolutions defined you may end up with a kernel patch
<Armbian-Discord> <l​anefu> And it's frustrating to make it work
