[meta-ti] booting 2.6.32 kernel and rootfs

Sounds like it is booting OK but the console is wrong.

Check into why you are getting this message also
** Unable to read "uEnv.txt" from mmc 0:1 **
as the kernel args ought to get read from there:

If they are not loaded then the defaults in the kernel will get used. You might want to check these also.
Not sure about your board/setup however try using /dev/ttyO0. You can test this from U-Boot also by altering the env vars

On my way to integrate Leopard imaging camera drivers into the beagle board image, I successfully built a minimal image with necessary camera drivers in the image, this is all after I integrated meta-ti layer with yocto.
I finally put the files in the card and powered up the beagle board.

This is what i'm getting..

AND NOTHING AFTER THIS... Any clue how to proceed..?

I posted in this mailing list, just because i'm using the meta-ti layer. Please do let me know if there is another one..!
