OpenWRT on Pogoplug v3/Oxnas (Pro/Classic)

This tutorial assumes you have completed my previous tutorial - Hacking the Pogoplug v3/Oxnas (Pro/Classic) with Debian
- and already running Debian from a USB drive on the Pogoplug V3.

OpenWRT will be installed on the internal flash (NAND) of the Pogoplug. You will still be able to boot Debian from USB when attached.

Known Issues:
 - RT3090 (PCIE) Wi-Fi in the Pro is not working. 

 - LED not working
- Other known issues from OpenWRT wiki

My console installation log can be found here.

All commands below needs to be executed from Debian.

OpenWRT Initial Boot via Telnet

At this point, we're ready to boot into OpenWRT. During the bootup process the LED on the Pogoplug will blink. However once it successfully boots into OpenWRT the LED will be completely off.

Note that by default, OpenWRT will default to 192.168.1.1 and will (or should) act as a DHCP Server.  Plug a network cable from your computer directly into the Pogoplug and power it on (do not plug the Pogoplug into your router). You should now be able to Telnet into the Pogoplug at 192.168.1.1 (username and password not required). If you're not able to telnet into the Pogoplug try setting a static IP address of 192.168.1.2 on your computer.

Note that SSH is disabled and will automatically start after a root password is set.

#set passwd and enable ssh
passwd

#Reconfigure Network to DHCP Client
#disable dhcp server on lan
#Ignore if any error.
uci set dhcp.lan.ignore=1
uci commit dhcp
/etc/init.d/dnsmasq restart

#set wired ethernet interface to dhcp client
uci set network.lan.proto=dhcp
uci commit network

#reboot
reboot

OpenWRT SSH and Initial Package Installation

Plug the Pogoplug and your computer back into your network/router. Check your router for the IP Address assigned to your Pogoplug. You should now be able to SSH into the Pogoplug.

Note that since we're using the daily snapshot trunk build of OpenWRT, you'll need to install your kernel packages right away (kmod-xxx), otherwise it will get out of sync.

opkg update

#Pogoplug has 128MB flash
#No need to be stingy on the packages
opkg install nano wget luci uboot-envtools pciutils usbutils htop wireless-tools kmod-rt2x00-pci kmod-usb-storage block-mount kmod-fs-ext4 kmod-fs-vfat kmod-fs-ntfs kmod-nls-cp437 kmod-nls-iso8859-1 e2fsprogs fdisk kmod-usb2 samba36-server samba36-client luci-app-samba kmod-rtl8187 wireless-tools kmod-usb-net-asix-ax88179 kmod-rt2800-lib kmod-rt2800-usb kmod-rt2x00-lib kmod-rt2x00-usb kmod-usb-serial-pl2303  kmod-usb-serial-cp210x  kmod-usb-serial-ftdi picocom screen

#Assume you're using the USB RT5370 Wi-Fi below 
#Regenerate Wi-Fi configuration

#Verify if Wi-Fi is working properly
rm -f /etc/config/wireless 
wifi detect > /etc/config/wireless

#If wireless is working properly, you should see something
cat /etc/config/wireless

#Enable Wi-Fi
sed -i 's^option disabled 1^option disabled 0^' /etc/config/wireless

/etc/init.d/network restart

Note that the built in Wi-Fi (PCIE) on the Pogoplug Pro is not working.

If you need wireless, I would highly recommend a USB Wi-Fi card based on the RT5730 chipset for less than $8.
