Here's how to allow your GuruPlug to boot from a USB drive.<br/>
You'll need an access to the serial console to achieve this, the JTAG module is OK.
* To connect to the bootloader, proceed exactly like for the Sheevaplug: http://wiki.amahi.org/index.php/Marvell_Plug_Computer
* Reset the GuruPlug.
* At the terminal, press enter a couple of seconds after boot to prevent it from booting using the onboard flash (Ubuntu). You should end up with a prompt.
* Some version of the GuruPlug have been shipped with a uboot that does not support Booting from USB, ESATA or SD-Card. If this is your case, then you have to upgrade uboot. To do this, the best howto I found is this : http://oinkzwurgl.org/guruplug_uboot
* There are some commands you need to run to make it permanently boot from the USB port ('''NOTE:''' this step is only necessary once):
setenv mainlineLinux yes
setenv bootargs_root 'root=/dev/sdb1 rootdelay=15'
setenv bootcmd_usb 'usb start; ext2load usb 1:1 0x6400000 /boot/uImage'
saveenv
While still under the bootloader , check your environment with ''printenv''.
It must look like this:
GuruPlug>> printenv
bootcmd=${x_bootcmd_usb}; ${x_bootcmd_kernel}; setenv bootargs ${x_bootargs} ${x_bootargs_root}; bootm 0x6400000;
bootdelay=3
baudrate=115200
x_bootcmd_usb=usb start
ethact=egiga0
x_bootcmd_kernel=ext2load usb 1:1 0x6400000 /boot/uImage
arcNumber=2653
mainlineLinux=yes
x_bootargs_root=root=/dev/sdb1 rootdelay=15
x_bootargs=console=ttyS0,115200
stdin=serial
stdout=serial
stderr=serial
