Step 11: Prep your linux box to update the kernel

The SheevaPlug ships with a firmware that can boot off of SD cards. So you need to update it over TFTP
Install a tftp server
yum install tftp-server

Get the u-boot image and make it available to the sheevaplug

cd /var/lib/tftpboot/
wget http://www.cyrius.com/tmp/u-boot.bin-3.4.19
mv u-boot.bin-3.4.19 uboot.bin
vi /etc/xinetd.d/tftp
change "disable  = yes " to "disable = no "

Add the script to load the ftdi driver when the SheevaPlug is connected:
vi /etc/udev/rules.d/85-sheevaplug.rules

# if no driver has claimed the interface yet, load ftdi_sio
ACTION=="add", SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_interface", \
        ATTRS{idVendor}=="9e88", ATTRS{idProduct}=="9e8f", \
        DRIVER=="", \
        RUN+="/sbin/modprobe -b ftdi_sio"

# add the sheevaplug VID and PID to the list of devices supported by ftdi_sio
ACTION=="add", SUBSYSTEM=="drivers", \
        ENV{DEVPATH}=="/bus/usb-serial/drivers/ftdi_sio", \
        ATTR{new_id}="9e88 9e8f"

# optionally create a convenience symlink for the console device
ACTION=="add", KERNEL=="ttyUSB*", \
        ATTRS{interface}=="SheevaPlug JTAGKey FT2232D B", \
        ATTRS{bInterfaceNumber}=="01", \

***Plug in the serial cable from the Sheevaplug, if a /dev/ttyUSBx is not created, reboot

your linux system

 Good Job! I have been keeping an eye on the sheevaplug and/or pogoplug for a few months now. It will be the perfect companion for a lot of complex projects. Plus the low energy consumption makes it really desirable.
