Linux SDK for ALFA AIP-W512 --------------------------- == Overview This toolchain allows you to build custom firmware image for the ALFA Network AIP-W512 Wireless AP/router. The SoC of this board is RTL8196E, based on a Lexra core (modified MIPS). Some applications have been added in the source tree: * dropbear * libpcap * tcpdump * ettercap == Disclaimer Flash at your own risk. == Requirements A linux host. This toolchain has been tested on 32-bit Ubuntu 9.10, 13.10 and on 64-bit Debian Jessie. == Configuration To configure the toolchain for the AIP-W512 board, use this command in top directory: > $ make menuconfig > Selected Target : rtl8196e > Selected Kernel : linux-2.6.30 > Selected Busybox : busybox-1.13 > Selected toolchain : rsdk-1.3.6-4181-EB-2.6.30-0.9.30 > Selected board configuration : 96E+88E GW > Config users : yes Then exit and save this new configuration. The next configuration screen allows you to choose built-in applications. (Only ettercap, dropbear and tcpdump have been tested at this time.) Again, exit and save this new configuration. ** Known issue ** If you get the error "Error : error opening terminal xterm", create this symbolic link: > # ln -s /lib/terminfo/x/xterm /usr/share/terminfo/x/xterm == Build > $ make Generated firmware image (rootfs+kernel) $top/image/fw.bin ** Known issue ** If you get the error: libtool eval: 1: libtool_args+=: not found libtool eval: 1: compile_command+=: not found ... you have to link /bin/sh file to /bin/bash : > # unlink /bin/sh > # ln -s /bin/bash /bin/sh > $ export SHELL=/bin/bash == Filesystem customization To customize /etc/ directory, you can edit files in $top/target/etc.default/. Otherwise, you can edit 'romfs' target in $top/target/Makefile to add files. e.g. to add a root directory: $(ROMFSINST) root /root You must rebuild to apply changes: > $ make == Flash A successful build generates few images: $top/image/linux.bin (kernel) $top/image/root.bin (rootfs) $top/image/webpages.bin (web pages) $top/image/fw.bin (kernel+rootfs+web pages) You have to flash fw.bin (never tried others) by following one of these methods: * TFTP (bootloader): - Connect LAN ethernet port of the device to your network - Find out serial port UART Pinout ->1 VCC (with arrow on PCB) 2 TX 3 RX 4 GND - Connect UART port with settings: 38400 8N1 > # screen /dev/ttyUSB0 38400 8N1 - Press 'Esc' key at boot to interrupt - Here a shell. Enter '?' to get help message - Enter 'IPCONFIG' command to display device's IP address, and modify if needed - Upload image by TFTP > $ atftp -p -l $top/image/fw.bin 192.168.1.6 * Web interface (tcp/80): In the menu >Management>Upgrade firmware Network configuration won't be altered. Default root password is 'root'.
