Hdmi settings?

[Erica]

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?

I've not used a pi, so I'm not familiar with

How that os configures it's uboot.

I've tried all the documented parameters with no luck.  I didn't know that hdmi was an interface that might not work.

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.

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.
