I don't believe any other distros are creating packages/images for Tegra yet. > As to using fat instead of ext2, this is just an example, and would be > (should be) customized for each vendor/distro. > I could also add a USB boot example. Really, we should be defining the boot architecture for Tegra, and distros following suite. So, I think we should just say: * Partition 1 of the media is /boot. * Partition 1 should be ext2 or compatible. * boot.scr should exist there and be a uImage script file. Distros certainly can't customize the U-Boot environment for themselves, since there's no generally applicable way of doing so. That's exactly why I pushed to load a boot.scr rather than having U-Boot load the kernel directly (and define the command-line), to give distros the ability to customize boot.scr; generating files in a filesystem is much easier for distros. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
