Hello guys,
I need your help.I am using Blaze tablet 2 with ICS (dailybuild 398 i.e. http://omappedia.org/wiki/L27.IS.2.M1_OMAP4_Icecream_Sandwich_Release_Notes) :
Presently I am following this wiki : http://omappedia.org/wiki/Bootargs_for_enabling_display
I want to check the framebuffer rotate option. So far here is what I have done.
My bootargs :
OMAP44XX TAB # printenv
bootargs=console=ttyO2,115200n8 mem=456M@0x80000000 mem=512M@0xA0000000 init=/init vram=10M omapfb.vram=0:4M androidboot.console=ttyO2
bootcmd=booti mmc1
bootdelay=3
baudrate=115200
ipaddr=128.247.77.90
serverip=128.247.77.158
netmask=255.255.254.0
bootfile="uImage"
stdin=serial
stdout=serial
stderr=serial
ethact=KS8851SNL
Environment size: 325/131068 bytes
As per the wiki it says pass omapfs.tiler=y and I have even set it. Now I want to fb rotate is not working.
I gave these commands :
cat /sys/class/graphics/fb0/rotate_type and the value is set to 0. Even if I issue echo "1" > sys/class/graphics/fb0/rotate_type its still says value as 0(zero).
echo "1" > sys/class/graphics/fb0/rotate (doesnt work).
Let me know what may be the issue. Sometimes when I give cat /sys/class/graphics/fb0/rotate_type its says " detected fb_set_par error, error code: -22 ".
Please help me.Thanks you.
