My note on Installing OpenWRT on Banana Pi R1 (BPi-R1)

Today, I just got my Banana Pi R1. Here is a simple guide to set it up as an OpenWRT router.

Step 1: Flash the TF(microSD) card.

Goto the download page of BPi-R1 (http://www.bananapi.com/index.php/download?layout=edit&id=65)
Find and download the latest OpenWRT Image, which is version 4.0 (01/09/2015) as I write this.
Write the OpenWRT image to the TF card. I use OS X, here is the code I used in Terminal:
Find the disk number of your TF card. Mine is disk2[Bold number may varies on your computer, wrong number will cause serious problem, you will lose your data on the wrong disk]:
```
diskutil list
```
Unmount it:
```
diskutil unmountDisk /dev/disk<strong>2</strong>
```
Write the image:
```
sudo dd bs=1m if=~/Downloads/BPI-R1_OpenWrt_V4.0.img of=/dev/rdisk<strong>2</strong>
```
If you are using other OS, follow the guide here (From Raspberry Pi, their are all the same except the image)
Eject the TF card from your computer and insert it into Banana Pi.

Step 2: Power On your Banana Pi R1.

Plug in the 5V power cord to the correct port, it will power on by itself.
HDMI is not working on OpenWRT(only works few seconds while booting)
Connect the BPI-R1’s WAN to your home router/switch’s LAN (Assume DHCP is enabled )
Find the BPI-R1’s IP address. You may find it in the web management interface of your home router. Scan port 80 and 22 for the whole subnet other wise.
use root/admin to login BPI-R1
Mostly Done.

After that, I found only 80M(VFAT) + 150M(EXT4) was used on BPI-R1, which waste pretty much space on my 32GB TF card.

Extra Step: Expand the ext4 partition. (Inspired by SaruMaaz)

Write Image to a Flash Drive (Assume the flash drive is disk2)

sudo dd bs=4m if=~/Downloads/gparted-live-0.24.0-2-i586.iso of=/dev/rdisk<strong>2</strong>;sync
