Here are the free pin :
the three which are not readable are from top to bottom : 7,5,6.
And the other pins and matching :
GPIO Number - assignement - Identification on board
4,8 - power led green, red - LED101 on board
11,2 - Internet Led green, red - LED110 on Board
3 - Adsl Led - LED109 on Board
9 - WPS Led - LED107 on Board
24 - WPS Button - SW703 ( Warning : C750 near switch should be removed to free gpio NOT TESTED !!)
10 - Wireless On/Off - SW704 ( Warning : C749 near green capacitor to be removed NOT TESTED !! )
23 - Reset - SW201
For the led, use the + sign pin to access corresponding gpio.
So if you uninstall led package : 10 free gpio pin, and with button packages removed : 13 !
Serial console : 155200,n,8,1
Serial console pin : GND - RX - TX - 3V3 ( the 4 wires on the picture )
OpenWRT flash : I use latest trunk ( own build ) : openwrt-DSL274XB-F1-EU-squashfs-cfe.bin
This board is not recognized by OpenWRT.
the trick :
- Boot with serial console,
- stop boot by pressing ESC.
- on prompt : CFE> type "b" to change board parameters. First choice is Board ID, choose 2 ( AW4339U )
- leave all other parameters with default configuration.
The board will have AW4339U code which is recognized by OpenWRT.
Attention : the switch will not work, in my use i don't care because i use WIFI
