Hello, when I searched the user manuals for 'hdmi', I came up with no results. The demo image would likely have this on it's UBoot, but the download link is being fixed right now. In the meantime, I am trying to display booting/linux output through HDMI using a few things that are supposed to work with other I.MX boards, and right now have tried the video parameters in all of my bootargs variables. Still nothing is shown through HDMI.
bootdelay=3
baudrate=115200
loadaddr=0x70800000
netdev=eth0
ethprime=FEC0
uboot=u-boot.bin
kernel=uImage
nfsroot=/opt/eldk/arm
bootcmd_net=run bootargs_base bootargs_nfs; tftpboot ${loadaddr} ${kernel}; bootm
ethact=FEC0
serverip=10.192.225.216
fec_addr=00:04:9f:00:ea:d3
ethaddr=00:04:9f:00:ea:d3
bootfile=uImage
bootcmd_mmc=run bootargs_base bootargs_mmc;mmc read 0 ${loadaddr} 0x800 0x1800;bootm
bootcmd=run bootcmd_mmc
bootargs=console=ttymxc0,115200 root=/dev/nfs ip=dhcp nfsroot=:/opt/eldk/arm,v3,tcp video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24
