Beagleboard Xm with mirrored display

Hello everyone,

I have a problem with my beagleboard xm that I just got.
I’m usuing the pre-built image that came with the board (SD card),
and the screen is displayed mirrored…
Does anyone knows how to fix that?
I tried:

echo "1" > /sys/class/graphics/fb0/mirror

but I get an error:
omapdss DISPC error: GFX_FIFO_UNDERFLOW, disabling GFX 

I also tried to create my own SD with TI instructions ([http://processors.wiki.ti.com/index.php/Sitara_Linux_Software_Developer%E2%80%99s_Guide](http://processors.wiki.ti.com/index.php/Sitara_Linux_Software_Developer%E2%80%99s_Guide)) but I have the same problem...

any ideas anyone? please... :)

Thanks! Aline.

Did you look here? It might be possible to change the mirror setting during boot (before the framebuffer is opened).

And I have seen the corresponding kernel config option (to mirror the framebuffer).

Hope it helps,
