The [ODROID U2 ] is an ARM development board, featuring a 1.7 GHz quad-core CPU (ARMv7a). This document contains notes about installing Funtoo Linux on this device.

Micro-SD Card Preparation
First, create the partition structure to suit your needs. In this example, there is a 128 MB boot partition, a 1 GB swap partition, and the remaining partition is for the root filesystem.
Disk /dev/sdb: 8018 MB, 8018460672 bytes 247 heads, 62 sectors/track, 1022 cylinders, total 15661056 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000ea6e7 Device Boot Start End Blocks Id System /dev/sdb1 * 62 245023 122481 83 Linux /dev/sdb2 245024 2251157 1003067 82 Linux swap / Solaris /dev/sdb3 2251158 15661055 6704949 83 Linux
Both sdb1 and sdb3 are formatted as ext4, and sdb2 is formatted as swap.
Funtoo Linux Installation
Follow the guide from [Funtoo_Linux_Installation_on_ARM] for
Kernel and Bootloader
Cross-compiler installation
In order to compile the Linux kernel for the ODROID U2, an ARMv7a hardfloat toolchain is needed. Install it using crossdev:
# emerge crossdev # crossdev -v -t armv7a-hardfloat-linux-gnueabi (also add -S if you want a stable toolchain)
Bootloader
The bootloader to use with the ODROID U2 is u-boot. Sources are not available yet. Source code present on hardkernel's github repository is not functional at the time of writing this page.
To be continued... All repositories containing u-boot do not work. A binary version has been found, but not tested yet.
Kernel Compilation an Installation
The kernel for the ODROID U2 can be directly compiled from the sources, given by hardkernel. Note that there are several branches (odroid-3.0.y, odroidx-3.6.y and odroid-next when this page was written), but we will stick with the default branch as it provides a defconfig for a simple start.
# cd ../odroid_u2 # git clone https://github.com/hardkernel/linux.git # cd linux # ARCH=arm make odroidu2_ubuntu_defconfig # ARCH=arm CROSS_COMPILE=/usr/bin/armv7a-hardfloat-linux-gnueabi- make -j8 (adapt depending on the number of cores available on the build machine) # ARCH=arm CROSS_COMPILE=/usr/bin/armv7a-hardfloat-linux-gnueabi- make modules_install INSTALL_MOD_PATH=/mnt/SD_root
