Unlike the Exynos Chromebooks, the Tegra Chromebooks do not use U-Boot as their firmware/bootloader - they instead use Coreboot (firmware) and Depthcharge (bootloader) like the x86 Chromebooks. You can, however, update your firmware with U-Boot as a legacy mode (Ctrl+L at the dev screen) payload - I've added Julius who can provide more detail about this process. Note that we do not maintain U-Boot support for these devices, but they are very similar to Venice2 which is well-supported upstream. I can't guarantee that a Venice2 U-Boot payload will "just work" though. -Andrew -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
