Exclamation How to rotate the LCD screen/framebuffer to 180 degree ?


I have one query regarding to frambuffer.

I have custom board with i.MX6Q SoC.

I am using Linux kernel 3.03.35 and LCD is 3.5 inch RGB type display.

I want to rotate my LCD screen to 180 degree. I tried a lot to pass parameters to > /sys/..../fbcon/rotate but nothing happen.

So Is there any way to rotating the screen without compiling the kernel. ?

Bcoz kernel compilation is my last option so I trying to rotate my screen via console Help me regarding oto this issue and give me solution for this.

I also founded some bit "IPU_ROTATE_180" in > /arch/arm/plat-mxc/include/mach/ipu.h and using by > /drivers/video/mxc/mxc_ipuv3_fb.c file.

I did some changes as below.

I passed "IPU_ROTATE_180" instead of "IPU_ROTATE_NONE" in "ipu_device.c" in > /drivers/mxc/ipu3/ but nothing change.

I also passed hard coded value (3 for 180 degree rotation as per enum) in "fbcon.c" file > / driver/video/console but nothing changes.

At where place/files/code should I changes in kernel tree ?

Please help me, its imp for me.

Thanks and Regards
