Thanks Wolfgang & Timur,
I think I want something like this:
setenv addr 20000000 fsload $addr uImage || fsload $addr uImage.new && bootm $addr
If the bootloader can't find uImage, try to find uImage.new.
Does that make sense? I'm using u-boot 1.2.0.
Matt

Hi,
I'm trying to figure out how to make my software field update process robust. Currently, my bootcmd is 'fsload 20000000 uImage; bootm 20000000'
Is there anyway for u-boot to determine, in one of these commands,
that
some command failed, and to do something else instead?
fsload 20000000 uImage && bootm 20000000
Or, without using the hush shell:
=> sete kaddr 20000000 => sete kload 'fsload ${kaddr} uImage' => sete kboot 'bootm ${kaddr}' => save
followed by "run kload kboot"
See http://www.denx.de/wiki/view/DULG/CommandLineParsing for details.
