A thread on the OpenWrt forum is related to this board. If you have any bugs or problems then put them on it :

• https://forum.OpenWrt.org/viewtopic.php?pid=112016

Currently there is some bugs with my previous patches. 
To make sure it will work once you get the full source, apply the following patches that fix a bug with 64 bit architecture and block-extroot: 
{{:patchesps.tar.gz|}} extract them at the root directory and run patch -p1 < patches

As the device only has 2MiB of NOR flash OpenWrt has to be stripped down to the strict miminum. First download the following file : filesps1208mfg.tar.gz and extract it at the root of the sources.

When building OpenWrt you have to launch make menuconfig:

In the menu go into

Target Profile (Broadcom BCM43xx WiFi)  ---> 

and in this menu select

Edimax PS-1208MFG

then go into

Global build settings  --->

And at the end select the two items. This will reduce the generated image size

Binary stripping method (sstrip)  ---> 
[*] Strip unnecessary exports from the kernel image 
[ ] Strip unnecessary functions from libraries 

Currently (when is currently? — orca 2011/08/12 14:15) there is a bug with stripping for library so don't select it, otherwise some mandatory functions will be removed from library and some programs will not work

Explore the configuration to see what is enabled and what is not (if not a bug seems to doesn't disable iptables)

Then you can type make

At the end of the compilation you should have a file ~/openwrt/trunk/bin/brcm47xx/OpenWrt-ps1208mfg-squashfs.bin

As the device has too few flash to store everything we will want to install we will use an external usb-key. The device has to be formatted into the following partitions :

1. sda1 : root partition in ext2
2. sda2 : swap partition

for example if your key is 1Gb then make an ext2 partition of 930Mb and a swap one of 70Mb Finally plug the key into the print server.

To flash the freshly built image to the server you will have to setup a TFTP server. For instance there is tftpd-hpa that is really simple to setup on ubuntu or any debian-based distro. There are a lot of good

tutorials for that on the net.

Now you'll have to plug your computer to the ps1208mfg (or at least be on the same network) and set you ip has 192.168.2.254. The bootloader expects to find a tftp server on this ip address containing a

file named upgrade.bin. For that you will have to copy the previous generated image into the tftp server directory and name it upgrade.bin

Once everything is setup plus the print server on the main power, and keep pressing the reset button using a pen. If everything goes fine (ie the print server find a tftpserver at 192.168.2.254 and succeed in downloading a file upgrade.bin) you will see the LAN led blinking fast for approximately 3 seconds (time to

download the firmware)

Then you will have to wait approximately 40 seconds. During boot you will see all leds lighting and then status and wifi will light off, this is normal.

→ basic.config

Leds are referenced as wlan and status in /proc/diag

→hardware.button

Using the reset button is pretty straight forward First create a /etc/hotplug.d/button/ folder. Then create a handler script like the following one :

#!/bin/sh
# $BUTTON = button name : reset here since we have only one button...
# $ACTION can be either pressed or released
# $SEEN is the time in second since which a button was pressed or released
# this is pretty useful to detect a long or a short press
#
logger button handler: $BUTTON $ACTION $SEEN

then with logread -f you will see each time you press the button
