Manual Build

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

Below are the details of Image build for Olimex A64-Olinuxino board.


git clone https://github.com/apritzel/arm-trusted-firmware.git
cd arm-trusted-firmware
make PLAT=sun50iw1p1 bl31
export BL31=/path/to/arm-trusted-firmware/build/sun50iw1p1/release/bl31.bin


git clone git://git.denx.de/u-boot.git
cd u-boot
make a64-olinuxino_defconfig


git clone git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
cd linux-next
make mrproper
ARCH=arm64 make defconfig
ARCH=arm64 make -j 4 Image dtbs
ARCH=arm64 make modules && ARCH=arm64 make modules_install


It’s easy to build entire system using buildroot and mainline supported a64-olinuxino already. See read this readme.txt for more info.

git clone git://git.busybox.net/buildroot
cd buildroot
make olimex_a64_olinuxino_defconfig


SD Boot

Prepare SD



Here, we can take mass storage as gadget function and will show how it can work with ‘host’ and ‘peripheral’ modes

Build otg mass storage as statically linked module with


Append bootargs with ‘g_mass_storage.removable=1 g_mass_storage.luns=1’


Plug USB otg cable A-type to host pc and B-type to bananapi
