[U-Boot-Users] uboot script parameters.

Hi:

Couple questions regarding u-boot scripts:

1) Is it possible to create proprietary u-boot script which takes parameters (like bash for instance):

setenv getkernel tftp 2000000 $1/uImage

where I used $1 for 1st parameter like in bash (u-boot may have different notation).

Then later I can run my script with arbitrary parameter:

run getkernel /images

2) Looks like u-boot doesn't support nested substitution of script parameters. For instance:

=> setenv sw_ver 1.0.10

=> setenv image_path rel/$(sw_ver)

=> printenv image_path

image_path=rel/$(sw_ver)

=>

Am I doing something wrong?

Thanks,

Leonid.
