= Getting the plug booting Fedora 12 =
Here are the steps to make the plug boot from USB
* General [http://fedoraproject.org/wiki/Architectures/ARM/SheevaplugUSB directions]
* Connect the ethernet cable to your network (Mouton says: is this necessary now? Can't we just wait until the Amahi Install section below to connect the plug to the LAN?)
* Connect the JTAG module to the SheevaPlug (be careful; connecting it the wrong way will fry it! See the warning sticker on the plug, and the photo on the box for proper connection), and connect the USB side to your computer (can be Windows, Linux or Mac).
* On Windows: install a driver (disc that came with plug), and [http://plugcomputer.org/plugwiki/index.php/SerialTerminal/Windows/PuTTY use PuTTY (serial)].
* On Linux, execute the following command, and use [http://sourceforge.net/projects/gtkterm/ gtkterm]: use 2 stop bits & 115200 bps speed when creating the profile; keep the defaults for the rest. Instead of gtkterm, you can also use the simpler screen: ''yum -y install screen; screen /dev/ttyUSB1 115200''

* Reset the device from the JTAG module (Mouton says: how? I tried to push the button, but that doesn't seem to reset the device... Do you mean login using the terminal emulator, and issue a reboot command..?)
* 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 ''Marvell>>'' prompt.
* There are some commands you need to run to make it permanently boot from the USB port ('''NOTE:''' this step is only necessary once):
{{Code|setenv mainlineLinux yes
setenv arcNumber 2097
setenv bootargs_root 'root<nowiki>=</nowiki>/dev/sda1 rootdelay<nowiki>=</nowiki>15'
setenv bootcmd_usb 'usb start; ext2load usb 0:1 0x6400000 /boot/uImage'
setenv bootcmd 'setenv bootargs $(console) $(bootargs_root); run bootcmd_usb; bootm 0x6400000'
saveenv
reset}}
* In order to install the rootfs onto a flash or disk, mount the flash drive on a linux system and execute the [http://dl.amahi.org/marvell/create-clean-f12-disk.sh create-clean-f12-disk.sh] script. You'll need to have the [http://dl.amahi.org/marvell/amahi-marvell-0.5.tar.bz2 amahi-marvell-0.5.tar.bz2] file in the current directory. It may take a while, but this must be done before booting up the plug and installing Amahi.
'''NOTE:''' This script is very dangerous (it can destroy the machine it is run on if not used properly). You will need to change the partition destination.
* Insert USB Flash Drive into the plug.
* Once this is complete, the JTAG module can be disconnected. There will be no need for serial connection any longer. Once the USB Flash Drive is connected and the plug booted, you will be able to connect via SSH (default root password is "amahi").
= Connecting to a Plug on a Mac =
On Mac OS X, Install the [http://www.ftdichip.com/Drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_2_14.dmg FTDI driver], download [http://dl.dropbox.com/u/3022105/Amahi/sheeva/Info.plist.patch Info.plist.patch] to your desktop, then run the following commands to connect to the SheevaPlug console:
{{Code|sudo patch -p0 < ~/Desktop/Info.plist.patch
sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext
sudo kextload /System/Library/Extensions/FTDIUSBSerialDriver.kext
screen /dev/tty.usbserial-[TAB]B 115200}}
For [TAB], hit the TAB key; the value there will be unique to each SheevaPlug computer, so TAB will allow you to auto-fill the correct value. Once connected, if you want to close your terminal session, hit Ctrl-A followed by Ctrl-K (or Shift-K on Linux). You'll be asked if you're sure you want to kill this window; just say yes!
