Test a SAMSUNG SSD DISK, the Read/Write performance are below:
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
2.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 bash
3.After you download the image, insert your TF card into your Ubuntu
* Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card
4.After step 3, then you can insert your TF card into R2, and press power button for around 10s to setup R2
Update Your Ubuntu On SD Card
1. Clone Bsp project from Github
* Execute "git clone git@github.com:BPI-SINOVOIP/BPI-R2-bsp.git"
2. Execute "./build.sh", to build your own uboot and kernel.
3. After finish built, Execute "cd SD", plug your Ubuntu TFcard in PC.
4. Execute "bpi-update -c bpi-r2.conf -d /dev/sdX", to update the compiled kernel to your TFcard.
Ubuntu On Emmc
1. 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 is ubuntu image we can get it from http://www.banana-pi.org/r2-download.html
* power off
* remove SD & power on
OpenWrt On SD & Emmc Steps
1. Clone OpenWrt project from Github.
* Execute "git clone https://github.com/garywangcn/bpi-r2_lede.git"
2. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.
3. 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/.
4. 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"
5. Execute "make -j1 V=s" to build your own OpenWrt image.
6. After built, we have two ways to install image.
(1) 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
(2) Write image to TF card, execute "dd if=mtk-bpi-r2-SD.img of=/dev/sdX"
(3) 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
7. 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.

GPIO Control
echo xxx > /sys/class/gpio/export
echo in/out > /sys/class/gpio/gpioxxx/direction
echo 0/1 > /sys/class/gpio/gpioxxx/value
Check the base gpio, you could see mine is 233
For example: if you want to change gpio 22 as out highlevel, you need input commands like this:
