Bananapi M64¶
This tutorial will show the details of Bananapi M64 board mainline support and other needed details, for more information about hardware and linux-sunxi
BSP Build¶
Manual Build¶
For manual building refer here for all necessary information.
Image building need host to ready with all necessary tools ready, refer here
Below are the details of Image build for Banana Pi BPI-M64 board.
ATF¶
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
U-Boot¶
git clone git://git.denx.de/u-boot.git
cd u-boot
make bananapi_m64_defconfig
make
Linux¶
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
Buildroot¶
It’s easy to build entire system using buildroot and mainline supported bananapi-m64 already. See read this readme.txt for more info.
git clone git://git.busybox.net/buildroot
cd buildroot
make bananapi_m64_defconfig
make
Booting¶
SD Boot¶
Partition the SD card in host with Single Falcon partition
Prepare SD
Write boot image
cd /to/u-boot
cat spl/sunxi-spl.bin u-boot.itb > u-boot-sunxi-with-spl.bin
dd if=u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=8k seek=1
Write rootfs, update boot/extlinux/extlinux.conf
git clone https://github.com/openedev/rootfs-sun64
cp -rf rootfs-sun64/* /media/jagan/rootfs/
cp /to/linux-next/arch/arm64/boot/Image /media/jagan/rootfs/boot
cp /to/linux-next/arch/arm64/boot/dts/allwinner/sun50i-a64-orangepi-win.dtb /media/jagan/rootfs/boot
sync && umount /dev/mmcblk0*
Insert the SD card and power-on the board. See the Linux boot start from SPL - unplug SD Card during U-Boot proper boot
USB Boot¶
Prepare SD card with from SD Boot and prepare USB mass storage with single partition by copying rootfs and update boot/extlinux/extlinux.conf
Insert the SD card, USB Mass storage and power-on the board. See the Linux boot start from SPL

U-Boot¶
USB Mass Storage gadget¶
We can use the board as a USB Mass Storage device:
You will be able to access all the partitions of any block device that is on the board or connected to it,
from your host PC - You will see them as /dev/sdXX, just like connecting a regular USB storage to your PC,
and you’ll be able to mount them, and have full read/write access to them.
We can even use it to flash a new U-Boot, re-partition the storage, re-format it, etc.
This is especially useful for updating the internal eMMC.
To do this you need to connect a USB cable between the OTG/Client port of the board and a regular USB Host port on your PC,
and use U-Boot’s ums command.
Linux¶
USB OTG¶
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
CONFIG_USB_MASS_STORAGE=y
Append bootargs with ‘g_mass_storage.removable=1 g_mass_storage.luns=1’
Peripheral¶
Plug USB otg cable A-type to host pc and B-type to bananapi
