[U-Boot-Users] bootcmd

[Matt Gessner]

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
