Bananapi M1

This tutorial will show the details of Bananapi M1 board mainline support and other needed details, for more information about hardware and linux-sunxi

BSP Build

Image building need host to ready with all necessary tools ready, refer here

U-Boot

git clone git://git.denx.de/u-boot.git
cd u-boot
make make Bananapi_defconfig
make

Linux

git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
cd linux-next
make mrproper
ARCH=arm sunxi_defconfig

SD Boot

FEL/USB Boot

More information here and build the fel tools from here

Insert SD card from and Press K3 located between the HDMI and USB host connectors and Power-on

Enter FEL
