DM355 + RGB LCD

Hello All,
finally I have been able to get full size image on display.
Actually the problem was I was trying to display image with different pixel depth than specified using fbset.
BTW now I am struck here...
As you can see here I want to display this image ..




And I am getting this on LCD...fairly good ..i dont know why it has been shifted...:(

But when I convert the same image into Gray scale , like this



And when I tried to display it.This is what i am getting on disply... you can see the problem.

I think his may be because my LCD is RGB666 type and I am displaying RGB565 as per FB_info given below.

root@192.168.2.207:/home# fbset -i -fb /dev/fb/0

mode "800x480-55"
    # D: 27.027 MHz, H: 29.124 kHz, V: 55.474 Hz

    timings 37000 40 40 29 13 48 3
    bcast true
    rgba 5/11,6/5,5/0,0/0
endmode

I demuxed GPIO from pinmux reg #1 like this. But it didn't help...

REG_PINMUX1 &= ~(1<<20);// for R2
REG_PINMUX1 |= (1<<21);
REG_PINMUX1 &= ~(1<<18);//for B2
REG_PINMUX1 |= (1<<19);

I have checkd on scope R2 and B2 pins are not working like R7-R3 / B7-B3.And G7 to G2 are working good

I have also checked VMOD register of VPBE but there isn't any specific bit to do this...

Can you please tell me how can I convert RGB565 mode to RGB666 or RGB888 ??

Thank you.

I tried bpp=32 also..

here are my boot logs...

Console: switching to colour frame buffer device 100x30

and also set fb using this...

fbset -fb /dev/fb/0 -xres 800 -yres 480 -vxres 800 -vyres 480 -depth 32 -nonstd 0 -laced 0

and the output of info command i could see..

but my image is 16 bit grey scale and I can not manage to convert it to rgba8888.

Any clue ??

thank you.

Folks ,

It was just a connection problem with my conector now its fine.

Its displaying nice colors.

But now I have one another problem.

As you can see I want to this image,

and I am getting this...

have you noticed the blue vertical strip on left hand side ?

I have tried setting left/right margins and HSYNC_length but the shifting and rolling over is always present...

can anybody suggest me what to do ?

Oops silly mistake agian..

I  was not removing BMP header ;)

after removing first 54 bytes its absolutely perfect now !!

thank you all for reading this ;)
