dd if=/dev/sda of=/dev/zero bs=1M count=10240\The Banana Pi R2 is a router based development board, which can run on a variety of open source operating systems including OpenWrt, Android, and Bananian. It has 4 Gigabit LAN ports, 1 Gigabit WAN, and 300Mbs wireless N capabilities.
| More Infomation: Banana Pi BPI-R2 |
MediaTek MT7623N, Quad-core ARM Cortex-A7
Mali 450 MP4 GPU
2G DDR3 SDRAM
1x Mini PCIE interface
2x SATA interface
4x Gigabit LAN 1x Gigabit WAN
BPI-R2 support 2 sata interface and onboard power port.
You can use sata line connect your hardisk on BPI-R2.
Test a SAMSUNG SSD DISK, the Read/Write performance are below:
Read from disk: 230MB/s
dd if=/dev/sda of=/dev/zero bs=1M count=10240\Write to disk: 192MB/s
dd if=/dev/zero of=/dev/sda bs=1M count=1024 oflag=direct\| Note: If you use 3.5 big hardisk ,you may need power with outside power. on board power maybe can not support enough current = Development Let’s get start to develop on BPI-R2, see amazing things happen. |
Prepare 16G/above TF card, USB-Serial interface, Ubuntu System
Using your USB-Serial (3.3V,Baud: 115200) Connect debug console on R2
Default IP address for LAN port: 192.168.1.1

You could download latest image from our forum
Here is the example image link: http://forum.banana-pi.org/t/bpi-r2-new-image-release-ubuntu-16-04-v1-3-2018-3-30/5293
Install bpi-tools on your Ubuntu. If you can’t access this URL or any other problems, please go to bpi-tools repo and install this tools manually.
apt-get install pv
curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bashAfter you download the image, insert your TF card into your Ubuntu
bpi-copy xxx.img /dev/sdxAfter step 3, then you can insert your TF card into R2, and press power button for around 10s to setup R2
Clone Bsp project from Github,Execute
git clone [email protected]:BPI-SINOVOIP/BPI-R2-bsp.gitExecute
./build.shto build your own uboot and kernel.
R2 build sh.png
After finish built, Execute
cd SDplug your Ubuntu TFcard in PC.
Execute
bpi-update -c bpi-r2.conf -d /dev/sdXto update the compiled kernel to your TFcard.
If you want to install Ubuntu on EMMC, follow these steps：
Burn an image to sd card, and set up R64 with sd card.
Copy the image which name contains "xxx-emmc-xxx" to U disk.
mount U disk to R64, then use bpi-copy to burn image to Emmc.
bpi-copy <XXX.img.zip>XXX.img.zip is ubuntu image we can get it from http://www.banana-pi.org/r2-download.html
power off
remove SD & power on
Clone OpenWrt project from Github.
git clone https://github.com/garywangcn/bpi-r2_lede.gitYou need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.
Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/.
Use "make menuconfig" to configure your image.
Choose "Target System" to config as "MediaTek Ralink ARM"
Choose "Boot Loaders" to config as "u-boot-bpi_r2"
Execute "make -j1 V=s" to build your own OpenWrt image.
After built, we have two ways to install image.
Plug your TFcard in Ubuntu PC, and enter to "build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/", you will find two images:
mtk-bpi-r2-EMMC.img
mtk-bpi-r2-SD.img
Write image to TF card, execute "dd if=mtk-bpi-r2-SD.img of=/dev/sdX"
If you want to install image to EMMC, We need another system which is running on SD card to program EMMC image to EMMC, please follow below steps to do:
Copy EMMC image to a running system which is from SD card
Program EMMC image to User Data Area of EMMC: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0 (assume /dev/mmcblk0 is for EMMC)
Unlock EMMC boot0 block: echo 0 > /sys/block/mmcblk0boot0/force_ro
Program preloader to EMMC boot0 block: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0boot0 bs=1M count=1
Change the Partition configurion of EMMC is 48h: reboot the system which is running SD, and enter the U-boot command line, run command emmc pconf 48 (for this steps, we can change partition configuration in userspace by using mmc-utils,see more information in BPI-R2 OpenWrt(LEDE) Souce code : 2018-04-11)
Power off, remove SD card, and then power on R2 board
This step is for upgrade, if you don’t want to install image after you built, you could use runtime upgrade.
Copy "bin/targets/mediatek/32/lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar" to R2 board which is running OpenWrt system(no matter where(SD or EMMC) it boots from), and then run command "sysupgrade lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar" to update both kernel and rootfs.

my network interface which can search internet is wan, and ip is 192.168.30.102, so I config ap0 as follows:
ifconfig ap0 192.168.30.188 netmask 255.255.255.0Run hostapd : “hostapd -d /etc/hostapd/hostapd.conf”
Config dhcp file : “vim /etc/dhcp/dhcpd.conf”
subnet 192.168.30.0 netmask 255.255.255.0 {
range 192.168.30.2 192.168.30.250;
option domain-name-servers 8.8.8.8;
option routers 192.168.30.1; }Config dhcp of ap0, then the devices which connect ap0 could get IP: "dhcpd ap0 -pf /var/run/dhcpd.pid "
And a bridge
brctl addbr br0
brctl addif br0 ap0
brctl addif br wan
Config br0 : “ifconfig br0 192.168.30.180 netmask 255.255.255.0”
Add br0 gw as : “route add -net default netmask 255.255.255.0 gw 192.168.30.1 dev br0”

Prepare a SD card which have installed Ubuntu system
Boot your SD card with R2, after R2 finish starting, copy your files and config your Ubuntu, then poweroff R2
Plug your SD card in Linux PC, "cd /media", then "ln -s <your account> pi"
Execute "bpi-migrate -c bpi-r2.conf -c ubuntu-mate-from-sd.conf -d /dev/sdx"
Then you could get your own image now
