Hi all, when i execute the command dfbg I obtain this result and my
display don't show anything
(please note there are some kernel messages into the result because
I'm using a serial console)
Directfb are cross compiled for a arm9 board with LCD-TFT driver.

Oh, that doesn't look good :-/
It seems that the framebuffer driver provides BGR instead of RGB.
I had one case where a driver pretends BGR, but actually it was RGB.
You can hack systems/fbdev/fbdev.c:1497 (comment out that line) and
see if colors are correct.
If not, you can either change the framebuffer driver or add BGR16
support to DirectFB, but I would prefer the former if possible :)
Here the modified code snippet, in case you have a slight line offset:
case 16:
if (dfb_fbdev_compatible_format( var, 0, 5, 5, 5, 0, 10,
5, 0 ) |
dfb_fbdev_compatible_format( var, 1, 5, 5, 5,15, 10,
5, 0 ) )
return DSPF_ARGB1555;
if (dfb_fbdev_compatible_format( var, 0, 4, 4, 4, 0, 8,
4, 0 ) |
dfb_fbdev_compatible_format( var, 4, 4, 4, 4, 12, 8,
4, 0 ) )
return DSPF_ARGB4444;
// HACK if (dfb_fbdev_compatible_format( var, 0, 5, 6, 5,
0, 11, 5, 0 ))
return DSPF_RGB16;
break;
