Hi,

Anyone had success using a Landzo display on Tinker Board S with Android?

https://www.amazon.com/Longruner-Capacit...dzo+7+inch

This display is pretty common and is sold under different brand names (Landzo, Longrunner, etc).

I had to put that in the Raspbian to make it work correctly on Raspberry (/boot/config.txt):

hdmi_drive=1
max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

When connecting it to Tinker Board, the Tinker Board doesn't turn on (the power indicator turns on but the "busy" led doesn't flash at all).

Everything is fine using a Raspberry Display on this Tinker Board so definitely some issue with that display.

I'm trying the support from the TinkerBoard team on GitHub: https://github.com/TinkerBoard/android-7...l/issues/9

What we got so far is that this display doesn't provide any EDID information (dmesg outputs are in the GitHub issue).

I tried several different ways to provide the resolution information to the Android but none of them worked.

Any ideas?

Keeping the information here as well.

Watching the UART of Tinker Board we found that the u-boot is looping for whatever reason, preventing the Tinker Board to boot with the display connected.

So, we are dealing with two problems: 1) boot 2) display resolution.

James Huang, from the tinkerboard team on GitHub, is going to buy a similar display to try to figure out what's going on there.
