Wired distorted boot image

[edu2004eu]

Okay, I've tried the TV64 image aaaaaand.... Same issue :/ distorted greyscale screen, I can make out a menu bar an the word favourites but that's about it. Any other thoughts?

Its a problem with an unsupported resolution, so I am afraid there is very little that you can do at the moment (especially using android). Could you try linux and report back ?  - I just want to know if the same thing happens if you boot into debian or ubuntu (how the internal scaler reacts).

Okay, I've given the Ubuntu image a try and its still Out Of Range although slightly different. its still greyscale but the image is now smaller and has a doubled up ghost image floating partially to the right of the original. :/

I'll try some of the others when I get a minute.

Hey,

I had a similar issue, where my TV wouldn't get any signal from the board. With Luke's help, we managed to get mine working (under Ubuntu) by forcing the resolution, so maybe it will solve your issue too.

I had to update my kernel and u-boot (there are scripts which do this in /usr/local/sbin -- just run them with sudo), then reboot, and then I had to add the following line to /boot/uEnv.txt:

Code:

extraargs=console=ttyS0,115200 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1280x720p50 rootwait rootfstype=ext4

This will force 720p (you can change the resolution to get 1080p, but I didn't spot any difference, so not sure). After saving the changes you do need to reboot.

I also had to unplug my HDMI cable and re-plug it in after rebooting.

Hope this helps!
