  1. Embedded XINUSW & HW preparation 09/5/2008 David You

  2. Software preparation • Download the Embedded XINU ver 1.0 • Cross-compiler • A cross-compiler from a host computer's architecture to MIPSEL (little endian MIPS) • http://xinu.mscs.mu.edu/HOWTO:Build_and_Deploy_XINU • Serial communication software • TFTP server software (30-day Trial version) • http://www.tftp-server.com/tftp-download.html

  3. Hardware preparation • Modified WRT54GL router • http://xinu.mscs.mu.edu/HOWTO:Modify_the_Linksys_hardware • Computer(s) • Run TFTP server • Compile the XINU with cross compiler • Connect the router trough the serial communication • An extra router • Establishing a small network between a computer and the modified router for downloading the XINU onto the router.

  4. Connection Network connection Serial Communication IP: 192.168.0.101 IP: 192.168.0.130

  5. How to download XINU onto the router? • http://xinu.mscs.mu.edu/HOWTO:Connect_to_a_modified_router • Check the connection among the devices. • Check the IP address given by the D-link router to the computer. • Run a TFTP server program and put the XINU boot image in a proper directory. • Make serial connection • 8 data bits, no parity bit, and 1 stop bit (8N1), 115200 bps. • Get the CFE prompt • First, push the CTRL+C with the serial connection open and then power on the WRT54GL. • Change the IP address of the network • CFE> ifconfig eth0 -auto • Download the boot image • CFE> boot -elf [TFTP server IP]:xinu.boot
