HDMI console display cropped on Cubieboard
« on: February 01, 2013, 04:54:04 AM »
Microcore on a Cubieboard (A10 processor) 1GB.

Using HDMI display - the console output is cropped by about 4 chars on lefth and top and bottom lines.  Change display mode in script.bin changes how much is cropped but somethign is always cropped.  HDMI overscan does not help. Linaro works OK on same setup.

I haven't found any script.fex setting that works. Is this "normal" or is it a cubieboard issue ?

Console, i.e., currently bterm works fine on a Cubie 512 machine using stock image. Have you tried the stock (Mele) image from download area? I know it would only see 512 but at least it might help determine next step to try. I do intend to rebuild to newer kernel to drop bterm and also plan to support sata. Cubie board looks promising.

I used the a10Core-20130123.img which I presumed was stock.

When booting the 1Gb Cubie with this not only was the image cropped (on 1080p60 about 4 chars on left and 1 line on bottom) but video did not always appear but restor of system was running.  Changing script.bin (e.g. 720p50) usually resulted in more screen being cropped.
When I upgraded the uboot etc for 1Gb - boot was reliable, system saw 1Gb ram and video appeared every time although stiull cropped.

Are you using a TV or monitor for HDMI output ?

Using TV HDMI
No problem.
Sorry, don't have DVI monitor to try.

Thanks for the reply.

I have the problem with a Panasonic TV HDMI.

I'm having the same problem with Cubieboard and a Samsung HDMI TV.
It works fine with the stock android 4.0 graphical interface image but it's cropping all around with debian console.

Typically the television has different setting to try.This is the easiest way.
Other than that you can try editing uEnv.txt and / or comparing script.bin with that which Andoid is using.
You will need bin2fex and fex2bin for such comparison or simply try your Android script bin..

Did you try the settings on TV?
Example, my Vizio has settings for Normal, Wide, Stretch, and Zoom.
I set my Vizio to Normal and all is OK using a cubieboard.

Yes I did try those, went thought all the menus, and read the manual twice, no option do disable overscan (if there is any).
I've had another hdmi device connected which also works fine with no cropping problems.
