Couple questions regarding u-boot scripts:
- Is it possible to create proprietary u-boot script which takes
parameters (like bash for instance):
No.
setenv getkernel tftp 2000000 $1/uImage
Note that this is a definition of an envrionment variable, not a script. A script is a different thing.
- Looks like u-boot doesn't support nested substitution of script
parameters. For instance:
It does, but only within the context of the "run" command.
=> setenv sw_ver 1.0.10 => setenv image_path rel/$(sw_ver)
Why are you escaping the / here?
Also note that you should ${sw_ver}. The old syntax $(...) has been deprecated and will cease to exist soon.
=> printenv image_path image_path=rel/$(sw_ver) =>
Try:
=> sete foo echo ${image_path} => run foo rel/1.0.10
Am I doing something wrong?
Yes, you make a MAJOR mistake:
