[Zafrullah Syed]

Hi all,

I am trying to build<http://gumstix.org/software-development/yocto-project.html>
a
bitbake target for my RobOvero board.I get this following error: "*ERROR:
u-boot was skipped: because UBOOT_MACHINE is not set*"

How do I set values and build uboot for Overo Series RobOvero board(PCB
30019-R3277)

Thank You.
