AM335x starter kit

Amey Ghanekar

Hi,

I am trying to display image (header stripped 480 X 272 ) on AM335x starter kit using cat image > /dev/fb0 command. I have observed offset in display. Image will clarify things in detail.

am335x-evmsk.dts

panel {
compatible = "ti,tilcdc,panel";
pinctrl-names = "default", "sleep";
pinctrl-0 = <&lcd_pins_default>;
pinctrl-1 = <&lcd_pins_sleep>;
status = "okay";
panel-info {
ac-bias = <255>;
ac-bias-intrpt = <0>;
dma-burst-sz = <16>;
bpp = <24>;
fdd = <0x80>;
sync-edge = <0>;
sync-ctrl = <1>;
raster-order = <0>;
fifo-th = <0>;
};
display-timings {
480x272 {
hactive = <480>;
vactive = <272>;
hback-porch = <43>;
hfront-porch = <8>;
hsync-len = <4>;
vback-porch = <12>;
vfront-porch = <4>;
vsync-len = <10>;
clock-frequency = <9000000>;
hsync-active = <0>;
vsync-active = <0>;
};
};
};
