[U-Boot-Users] uboot script parameters.

[Leonid]

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.
