My prototype DM6467+THS8200 system takes 2 minutes to get running after power on. I have other irons in the fire to shorten boot time, and in the past I showed proof of life on a system with ADV7171 instead of THS8200 by modifying the driver to turn on the DaVinci clock and configure the ADV7171 to generate color bars.
I could do the same color bar thing with the THS8200 driver, but that still takes on the order of a minute delay after power on.
Instead, I'm wondering about modifying the U-Boot code to configure DaVinci clock and THS8200 color bars. This might give me a second or less to get video output after power on, and thus pretty quick "proof-of-life".
Do you think this is doable? Where's the best place to get good, appropriate U-Boot source code? Do I compile it on my Ubuntu linux VM (Win7pro host)?
Thanks very much,
