U-Boot for the Lenovo Ideapad Yoga 11 tablet

Quick Start

• Build U-Boot

• Boot

Build U-Boot

$ export CROSS_COMPILE=arm-linux-gnueabi-
$ make ideapad-yoga-11_defconfig
$ make

After the build succeeds, you will obtain the final u-boot-dtb-tegra.bin image, ready for loading.

Boot

Currently, U-Boot can be preloaded into RAM via the Fusée Gelée. To enter RCM protocol use power and volume up key combination from powered off device. The host PC should recognize an APX device.

Built U-Boot u-boot-dtb-tegra.bin can be loaded from fusee-tools directory with

$ ./run_bootloader.sh -s T30 -t ./bct/ideapad-yoga-11.bct

To boot Linux, U-Boot will look for an extlinux.conf on MicroSD and then on eMMC. Additionally, if the Volume Down button is pressed while loading, the device will enter bootmenu. Bootmenu contains entries to mount MicroSD and eMMC as mass storage, fastboot, reboot, reboot RCM, poweroffand enter U-Boot console.
