AM335x display rotation

bikash bag

Hi,

I am trying to rotate the display by 180 degree using the below command, but it's not rotating and the screen is becoming blank for some time.

echo "2" > /sys/class/graphics/fb0/rotate

the kernel version I am using is 3.2.0

Thanks

issue solved, we are using gpio3_10 for lcd scan direction, when I made the gpio low by gpio_direction_output(), I am able to see the display 180 degree rotated.

Thanks

Hi Bikash,

Did you connected the GPIO3_10 to LCD ?
If yes, May i know where & how you connected GPIO3_10 to LCD ?

(Or)

It is solved by just changing in the software ?
If only changes i software, can i get the patch file ?

Please help me in this.

Thanks in advance.

Best Regards,
Bhaskar
