Installation

Everything except U-boot is already present in the Generic ARM tarball on the download page.

Compile U-boot

Download the u-boot repository

   git clone --depth 1 git://git.denx.de/u-boot.git

then configure and compile u-boot

   make CROSS_COMPILE=arm-linux-gnueabihf- A20-OLinuXino-Lime2_defconfig
   make CROSS_COMPILE=arm-linux-gnueabihf-

This should output a combined SPL file with u-boot called u-boot-sunxi-with-spl.bin

Prepare an SD Card

1. Create a DOS partition table and a primary partition on your card.

   fdisk /dev/sdX

Start the partition at sector 2048, change its type to W95 FAT32, and set its bootable flag. 2. Create a FAT filesystem on the new partition.

   mkfs.fat /dev/sdX1

Copy Data to the SD Card

1. Copy u-boot to the SD Card at offset 8k (specific to Sunxi).

   dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8

2. Mount the partition and copy files from the Generic ARM tarball onto it.

After Installation

The default login is root, HDMI should work out-of-the-box, ethernet is off by default. The Installation page should guide you from here.
