To send a test email....... type this with your email address

Out of space..........

I ran out of memory so couldnt install any more packages. A way around this is to copy the filesystem to a usb drive and run from there, however you will need to format theusb drive on another device as there isnt enough memory on the Tl-WR703n for the software....

format usb on another box

list drives
ls /dev/sd*

format it to ext3
mkfs.ext3 /dev/sda1

remove and plug it into router

-NOTE I had already installed motion, so i had no more space at this step, the only round this was to reset it to default in luci >system>backup/flash firmware which will reset it to a clean openwrt install freeing up some room.

list drives
ls /dev/sd*



If usb not found then install usb storage support
Update package list
opkg update

Install USB storage support
opkg install kmod-usb-storage
you may get an error, just reboot and repeat

list drives again and it should show up as sda1
ls /dev/sd*

install ext4
opkg install kmod-fs-ext4
got error but ignore

install block-mount
opkg install block-mount

Now we copy the file system to the USB drive. (One command per line.)
mkdir -p /mnt/sda1
mount /dev/sda1 /mnt/sda1
mkdir -p /tmp/cproot
mount --bind / /tmp/cproot
tar -C /tmp/cproot -cvf - . | tar -C /mnt/sda1 -xf -
umount /tmp/cproot
umount /mnt/sda1

Step 4

Now need to make a small adjustment to the /etc/config/fstab file.
/etc/config/fstab

config mount
        option target        /
        option device        /dev/sda1
        option fstype        ext3
        option options       rw,sync
        option enabled       1
        option enabled_fsck  0

reboot

After rebooting the router, connect again to it (via SSH). By subsequent command you can test, if everything worked fine.

Show mounts
df

In the line rootfs you should now see that the storage capacity is the same as the one of your USB flash drive.  A look into the router’s web backend (at the System->Software tab) should also disclose whether everything went fine.

Next i need to reinstall motion :(

Part of this came from....
http://en.code-bude.net/2013/02/16/how-to-increase-storage-on-tp-link-wr703n-with-extroot/

Autostart Motion when OpenWRT boots

Make sure the config file is set to daemon mode - this lets openwrt run in the background
Open /etc/motion.conf using WinSCP and make sure daemon is set to on...

daemon on

save and close

Then load on boot.....

Open /etc/rc.local using WinSCP and replace with the following....

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
motion -c /etc/motion.conf
exit 0

Save and reboot, then it will then load automatically on startup.

Edit.......
I had an intermittent problem on reboot
In the kernel log on reboot I was getting:-
UVC non compliance - GET_DEF(PROBE) not supported. Enabling workaround.
It worked if I unplugged the camera and plugged it back in, or I power cycled the router just not on reboot (using reset button or from reboot in luci).
To get it working reliably on reboot, I had to edit /etc/modules.d/video-uvc to read

uvcvideo quirks=0x100


save and reboot

Webcam Streaming

So I decided to add a webcam -  its a Microsoft LifeCam NX-3000

Notes - I used OpenWrt Barrier Breaker 14.07
see my  Flashing firmware post


1: install uvc drivers: kmod-video-uvc (I did this from luci software menu)
2: install motion (I did this from luci software menu)
3: reboot

4: check camera is recognised - should appear in /dev/video0:

ls -al /dev/video0 (I did this in putty)

If all is good then.......

5: edit the config file stored in  /etc/motion.conf (I used WinSCP)

change the entries below......

daemon off
this will turn off daemon mode (so that in putty you will get an output to tell you what is going on for testing)

v4l2_palette 8

output_pictures off
to stop you running out of memory after 5 pictures!
note you could add a usb hub and mount a memory stick for extra memory then change
target_dir to your memory stick.
stream_localhost off
this will let you view the stream remotely ie not just from the localhost!

6: Save the config file

7: start motion from putty: motion -c /etc/motion.conf

open firefox on a pc (internet explorer didn't work) and goto http://192.168.1.1:8081/
or whatever the ip address of your router is.

And Voila......

On

Flashing with openwrt

I used OpenWrt Barrier Breaker 14.07
Download the firmware to your pc:
http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

Then login to the router and upload it to replace the chinese firmware.....

The router I had came with chinese firmware - log into it with the username and password printed on the back of the box and then follow below





You will loose connection while it flashes the firmware, and i can take 5 mins or so.
Once its rebooted you can login via ethernet cable on 192.168.1.1
