June 20, 20242 yr Hello, I have a 5.5" waveshare hdmi screen. For some reason it is blank on all my SBCs. Vim3, vim4 with armbian so far. It works perfectly for my Mac mini running Arch. I've tested cables and power. It has instructions for special settings to add to pi os' /boot/config.txt. Hdmi_force_hotplug=1 Among other things. Is it possible I need the same for armbian? Where would that go?
June 20, 20242 yr Author I've not used a pi, so I'm not familiar with How that os configures it's uboot.
June 21, 20242 yr Author I've tried all the documented parameters with no luck. I didn't know that hdmi was an interface that might not work.
June 21, 20242 yr Can't really help with meson, but if this will make you feel not alone - rockchip also has issues with HDMI IMHO worth trying search in aml section of this forum. If patches are required, you might want to look into libreelec and minimyth2 GitHub repos. Since both are TV oriented, they might have necessary patches.
June 21, 20242 yr Author Thanks for the response, I will dig around some more. Screens in general seem to have a lot of Dificulties. I'd rather have mipi, but that rarely works.
