Beagleboard xm 7inch LCD display issue

Anyone knows where to modify the out display? I need connect a 7inch LCD to my beagleboard, everything is fine, except the LCD display is offset, shifted to right and down.

I need move the display to fit the 7inch LCD, not don’t know where to change.

Many thanks.

run this little macro in u-boot before booting the kernel..

i2c dev 1 ; i2c mw 40 00 00; i2c mw 40 04 80; i2c mw 40 0d 05 ; i2c dev 0

supposedly there is a kernel driver for this lcd to do it to, just
haven't got it to work yet, so i've been using that hack..

On the beagleboard, in u-boot before you load the kernel..

BTW: the 12.10/13.04 demo images on elinux already implement this by default...

Hi Robert,

I have installed the ubuntu 12.10 and the LCD7 screen works well, the GUI desktop is shown correctly. But the touch screen still does not work. Trying more tomorrow.

Good to hear..

yeap, that's a known issue with the v3.7.x branch, you'd have to go
all the way back to my v3.2.x branch where the touch did work.. Now
i'm just waiting for some user who's interested in fixing to actually
fix it.. I don't have any free time this week to work on it..
