Hello, 

 

                I am used to ltib to please forgive me for my newbie
questions. I have created the fsl-image-gui from the tutorial on the
freescale website and are the steps to create your own sd card image
(manually copy uboot, uImage, and filesystem) the same as ltib? 

 

Also I am using an HDMI display, how do you can the uboot setting in the
fsl-image-gui to output the display on HDMI?

No, it's not.

You will find your image under:

<yocto_folder>/build/tmp/deploy/image/fsl-image-gui-yourboard.sdcard

you need to:

sudo dd 
if=<yocto_folder>/build/tmp/deploy/image/fsl-image-gui-yourboard.sdcard 
of=/dev/sdb

In order to change your display, the process is the same.

Boot the board.
press any key.
you can see u-boot prompt.

printenv

and add your code to mmcargs

Alexander,

Here's the setting from my u-boot.

bootargs=console=ttymxc0,115200 root=/dev/mmcblk1p1 rootwait rw
video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb0:dev=hdmi,1920x1080M@60
,if=RGB24

You can set by typing following command which you can get from Sabre SD
User Guide.
setenv bootargs 'console=ttymxc0,115200 root=/dev/mmcblk1p1 rootwait rw
video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 video=mxcfb0:dev=hdmi,1920x1080M@60
,if=RGB24'

Thanks,
He
