DM355 EVM does not display video demo

It looks like it successfully ran loadmodules.sh because of the cmem output, so with no other errors I would have expected something to show up on your display. My first thought would be that this is some issue with the configuration in U-Boot, so I would verify your bootargs U-Boot environment variable, in particular if you have a PAL TV and are outputting NTSC or vice versa.

Hi Bernie,

Thanks for replying!

I checked both PAL and NTSC setup. My TV is NTSC. I only saw a flash of white screen on the TV and that was it. No other graphic.

Please let me know if you have other suggestion or something I can try. I looked into the help from UART, does not seem to have a hw diagnostic or anything to try.

Regards,

Pho

Can you post a log of your u-boot varaibles as well as the full boot log (perhaps as an attachment)?  This will better enable us to pin-point the problem.  Thank you in advance.

Aside from posting up your U-Boot arguments as Juan suggests, it may also be worth trying another TV or disconnecting and reconnecting the video cable. I have seen a few cases where one of the monitors I use gets in a bad state sometimes where you end up with a flash on the screen and than it stays blank until the video cable is disconnected and reconnected, its a long shot  but may be worth a try.

Thanks, again!

U-Boot log is attached (or below)

I did try different TV and cable, etc. [:)]
