Everything else appears to work normally.

Hi,

It is common warning for u-boot: http://www.denx.de/wiki/view/DULG/WarningBadCRCUsingDefaultEnvironment (http://www.denx.de/wiki/view/DULG/WarningBadCRCUsingDefaultEnvironment)

QuoteAnswer:
Most probably everything is OK. The message is printed because the flash sector or ERPROM containing the environment variables has never been initialized yet. The message will go away as soon as you save the envrionment variables using the saveenv command.

Nothing to worry about and the fix is easy.

It's a normal error.
It means that memory is not currently initialized
