IPS50 display not working on 0.3.5-24.2.0-trunk - can someone else please verify?

[alexvnesta]

What happened?

I haven't had the time to check older trunk releases - can someone please confirm this is a real regression on 0.3.5?

On both the Debian bookworm edge (Armbian-unofficial_24.2.0-trunk_Mkspi_bookworm_edge_6.7.5.img.xz) and the ubuntu jammy current (Armbian-unofficial_24.2.0-trunk_Mkspi_jammy_current_6.6.17.img.xz) my genuine Makerbase ips50 display is not working.

Specifically - The backlight illuminates, but there is no display output. I have all three cables connected - Usb, 24v power, and HDMI. Just the backlight illuminates, nothing more. I just got this display, so I can't confirm if it worked on a previous build.

My display does work when plugged into a normal windows pc.

Here is some info - when I only specify extraargs=video=HDMI-A-1:e or no extra args at all.

Boot takes forever and keeps trying to resolve the below errors.

When I add the resolution and hotplug to my /boot/armbianEnv.txt, the startup does not throw any errors and is fast, but I still get no display out, just backlight.
