LVDS resolution problem

BSP: fsl-community-bsp (fido branch)

Kernel Version: 3.14.28

Board: SabreSD (mx6q)

LCD: Innolux 1024x600 LVDS

no X11 (frame buffer use)

Kernel command line: console=ttymxc0,115200 root=/dev/mmcblk2p2 rootwait rw video=mxcfb0:dev=ldb,1024x600M@60

u-boot lcd resolution is OK

but linux lcd resolution is always 1024x768

for examples

1. gstreamer

gst-launch v4l2src device=/dev/video0 ! 'video/x-raw-yuv, format=(fourcc)UYVY' ! mfw_isink

than ==>

MAX resolution 1024x768
