Normally it is expected that hardware directly launches U-Boot that loads and starts GRUB which then loads and starts kernel (or whatever). Do you really want to start U-Boot from within GRUB?Yup, similar like says in Linaro wiki [0]. In this case, it explains how to running GRUB on U-Boot on Versatile Express. In my case, i would begin to start U-Boot from within GRUB for BeagleBone board.
How do you start GRUB in the first place? On U-Boot platforms GRUB cannot be run without U-Boot at all (it relies on U-Boot API for disk/net IO), so the simplest way to get back to U-Boot is to exit GRUB :)
Otherwise please explain in more details how you build and start GRUB on this platform.
