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. Compex loader version 2.54 or above. 2. OpenWRT will only be supported on WP543 with 4MB NOR flash and above. 3. Please ensure that the Ethernet connection is able to ping address = 192.168.168.1 4. If there is a USB NAND flash available on board, you would need to change the loader configuration. Please refer to “what to do if there is a onboard NAND Flash”.
1. Getting source codes
svn co –r 12448 https://snv.openwrt.org/openwrt/trunk
2. Apply patches from the files mod-wp543.tgz
tar zxvf mod-wp543.tgz
cp –a mod-wp543/* trunk/
cp wp543.config .config
OpenWRT Firmware will be in bin/openwrt-ar71xx-wp543.bin
a. Via Compex Firmware
*Put the AP in Firmware Upgrade mode and upload the file. *This file is for WP543 with 4MB or 8MB NOR flash. b. Via TFTP *Go to the firmware upgrade mode (By pressing and hold the Reset button and plug-in the power adapter). *Upload the OpenWRT image to the device (tftp –i 192.168.168.1 put openwrt-ar71xx-wp543.bin)
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.
