[meta-freescale] iMX6, SabreSD. Yocto HDMI monitor problem

[Qiong Wang]

Hey, Sir, I follow the
http://wiki.wandboard.org/index.php/Getting_started_with_Yocto_on_Wandboard
and
http://wiki.wandboard.org/index.php/Building_Qt5_using_yocto_on_Wandboard .

I build the image but there is no input signal on my HDMI monitor.
I checked this post  https://community.freescale.com/docs/DOC-94989

If using HDMI please, modify u-boot environment arguments:
>
> *setenv mmcargs "setenv bootargs console=${console},${baudrate}
> root=${mmcroot} rootwait rw video=mxcfb0:dev=hdmi,1920x1080M at 60,if=RGB24"Bu*
>
>
>

But I donno how to do this, I have been stuck here for days, could you
please help me?

Regards

Qiong
