Hello, I made a custom distro for a project, but i couldn't figure out how to make the HDMI output work on the kernel configurations
I started with sunxi_defconfig (linux 5.8.13), and then disabled module support, making it with built-in drivers On testing, i had no HDMI output and the following error on dmesg: sun4i-drm display-engine: [drm] *ERROR* fbdev: Failed to setup generic emulation (ret=-12) After that, i tried another distro (armbian) to see if that was a hardware issue, but it wasn't. I tried to imitate their configuration and even making it modular, but the error persisted Sometimes i also had an error "couldn't find any crtc's or sizes", which i "fixed" by hardcoding a screen size, but after a reboot, the generic emulation error went back again with no explanation. This crtc error was consistent one time i tried with modules and a manual module order I tried to ask on stackexchange as well, but it received no replies (https://unix.stackexchange.com/questions/616407/why-the-hdmi-output-doesnt-work-on-orange-pi-one) Is this a driver issue, or i'm doing something really wrong? -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
