If you want to upload firmware to router by tftp, you will have to turn your device to this mode. The procedure is following:
Set your ethernet interface into static mode (IP address 192.168.168.10, netmask 255.255.255.0, default gateway 192.168.168.1), put your router into Restore mode and upload the firmware by TFTP using the following commands (replace XXXXXX with wp543):
$ tftp 192.168.168.1 tftp> binary tftp> trace tftp> put openwrt-ar71xx-wp543.bin
Diagnostic LED will now stop blinking for a while; if the flashing procedure is successfully done, it will start blinking slowly. Now reboot your router manually (turn off - turn on) and OpenWrt will boot.
1. Getting source codes
svn co –r 12448 https://snv.openwrt.org/openwrt/trunk
2. Apply patches from the files mod-wp543.tgz (resource url)
tar zxvf mod-wp543.tgz cp –a mod-wp543/* trunk/
cd trunk cp wp543.config .config make
OpenWRT Firmware will be in bin/openwrt-ar71xx-wp543.bin
a. Via Compex Firmware
b. Via TFTP
Both madwifi and ath9k work well with all Compex MiniPCI cards. You will need some wireless authenticator and/or supplicant (wpad-mini/wpad/wpa-supplicant/hostpad/hostapd-mini).
Madwifi doesn't support MAC changes through UCI on this architecture. If you want to change of wireless MAC, see this.
