uEnv.txt options

Hi all

I've been working with beagleboard xM revB boards for a while at work but my company recently bought revC boards and I just can't figure out how to modify uEnv.txt to my needs. I want to change rootfstype to ext2, the mem argument for the DSP to work and some other things that worked with boot.scr. I also tried to load boot.scr from uEnv.txt with

loaduimage=fatload mmc ${mmcdev} ${loadaddr} ${bootenv}
mmcboot=echo Running boot.scr script from mmc ...; source ${loadaddr}

but it didn't worked. I'm also using the MLO from the demo image that came with the board, but another uImage from Angstrom.next repo (2.6.39)

Is there any other way to make this uEnv.txt work like boot.scr or any documentation about the change and the new syntax?

Thanks, Adam

Strange, that's exactly what i've been doing with my ubuntu demo
images, and it's working fine for me..

Can you share your serial boot log from power up along with what you
have saved in boot.scr and i'll take a look at it..


Thanks for the reply

[...] This appears at least a 50 times so I cannot catch what was before it and in the end:
