Frame buffer resolution in i.Mx6 Yocto

[MuhammadhSalih]

Hi,

I am using i.Mx6Q processor with the Yocto BSP release of fsl-yocto-L3.14.38_6qp-ga (imx-3.14.38-6QP_ga). I have tried to Launch the Yocto filesystem in my customized platform with GUI in my LCD-display (800x480). While dumping any image into it, the image is not properly visible.

I have found that there is a change in the virtual X/Y resolution of display. Below is the command executed to check the same:

root@board:~#

root@board:~# fbset

mode "800x480-60"

    # D: 33.260 MHz, H: 31.496 kHz, V: 59.993 Hz

    geometry 800 480 832 512 16

    timings 30066 88 40 33 10 128 2

    rgba 5/11,6/5,5/0,0/0

endmode

root@board:~#

Here the virtual X/Y resolution is increased by 32 (832 512) instead of (800 480).

Is it even number aligned resolution?. Please suggest me to solve this issue.

Regards,

Salih

You can change virtual resolution with the command like this:

# fbset -vxres 800 -vyres 480

Have a great day,

Victor
