Black A13-LCD4.3

[adomenech]

I conected the A13-LCD4.3 with a Debian release 2, the procedure to calibrate the touch screen worked fine, but I can not see anything on the screen

Any clue what this can be about?
Thank's
Albert

What do you mean you can't see anything?
You are posting a screen output.
Do you mean you cannot see the buttons that allow you to quit the test program?
They become invisible once the screen output covers them with numbers.
The quit button is still in the same spot, in the top right corner, just move around in that area until you get your command prompt back.
Post back for more details if this isn't what you meant.

Sorry I seen that a bit late. What I mean is that I just see black screen on the LCD4.3, what I posted is the outpout of a ssh terminal session. I thougth to see the LCD turned on as well, perhaps i'm wrong but what I read is that with this binaries the LCD is activated  by default. I didn't deal with resolution configuration allready but thougt I could see some kind of response from the display

Regards

I believe HDMI is the default output.x
To change it, got to the 17 MB partition on the SD card,
go to the 480x272_LCD folder (the name is longer and weirder than this)
copy the script.bin file
go back to the root folder of the 17 MB partition (there is already a script.bin file there)
paste your file there and overwrite
reboot
