Broken boot loader

[Tango Drango]

does anyone know what the default bootcmd environment variable is?

You can always restore default environment with:

Code:

env default -a

Note that it restores settings for current "session", to persist do:

Code:

env save

For more details see:

This is exactly what I was looking for - much appreciated. Must've been searching for all the wrong things to miss that in the u-boot documentation.
