Is there a boot.scr file in the same directory as the boot.txt file? If
there is, then the boot.txt file is only showing the text contents of
boot.scr file. To make a change to the boot script you need to; first
make the changes in the boot.txt file, second run this command:

mkimage -A arm -T script -C none -d boot.txt boot.scr

Incidentally, if mkimage isn't installed on your system then
"apt-get install u-boot-tools" will install it.

Best regards,
Matt
