Hi,

I am using a omap3530 
<http://focus-webapps.ti.com/general/docs/sitesearch/searchdevice.tsp?partNumber=omap3530> 
based board. I am trying to rotate the LCD 
using*/sys/class/graphics/fb0/rotate*. The rotation works only for 0 
degree and 270 degrees.

When trying to rotate for 90 or 180 degree it give error message 
*detected fb_set_par error, error code: -22 *and does not rotate.

The log output is below.*
*

/ # cat /proc/cmdline
omapdss.def_disp=lcd30 console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw 
rootfstype=ext3
  rootwait lpj=1949696 omapfb.rotate=1 omapfb.rotate_type=1 
omap_vout.vid1_static_vrf
b_alloc=y omapfb.vrfb=y
/ # echo "0" > /sys/class/graphics/fb0/rotate
detected fb_set_par error, error code: -22
/ # echo "1" > /sys/class/graphics/fb0/rotate
/ # echo "2" > /sys/class/graphics/fb0/rotate
detected fb_set_par error, error code: -22
/ # echo "3" > /sys/class/graphics/fb0/rotate
/ # echo "1" > /sys/class/graphics/fb0/rotate

Can some one help me in solving this issue.

Regards,
