In Linux BSP, by default, the LCD framebuffer is not enabled. SEIKO and CLAA driver are also disabled.
The kernel need be re-configure to enable LCD framebuffer.
In kernel configuration menu, go to device drivers -> Graphics Support
Select "SEIKO WVGA Panel"
Select "CLAA WVGA Panel"
Deselect "E-ink Panel Framebuffer"
Select "Support MXC ELCDIF framebuffer"
Then in command line:
1. with SEIKO LCD (connected on J13)
setenv bootargs_mmc 'setenv bootargs ${bootargs} console=ttymxc0 root=/dev/mmcblk0p2 rootwait rw lcd=1'
2. with SEIKO LCD (connected on J12)
setenv bootargs_mmc 'setenv bootargs ${bootargs} console=ttymxc0 root=/dev/mmcblk0p2 rootwait rw lcd=1,j12'
2. with CLAA LCD
setenv bootargs_mmc 'setenv bootargs ${bootargs} console=ttymxc0 root=/dev/mmcblk0p2 rootwait rw lcd=2'
