= Accessing the SheevaPlug serial console from a Windows 7 box =
# Connect the device using the mini USB -> USB cable.
# Chances are Windows will struggle to find drivers for the device so just use the SheevaPlug_Host_SWsupportPackageWindowsHost.zip file that is included in the DevKit CD. Unzip it and use Device Manager to browse for the TeraTerm Drivers (located as a sub directory in the zip file you just extracted).
# Windows will find 2 devices (USB Converter A and B) A = JTAG port B = serial port. We want to connect to the serial port.
# Click on Port B, select properties and in the Advance tab ensure LOAD VCP is selected.
# Unplug the device, and plug it back in.
# Using PuTTY, connect to the COM port of "PORT B" and make sure the SPEED is set to 115200.
# You might need to press ENTER once or twice to get the prompt to actually show (sounds silly but it took me a while to figure that out lol).
# Login using the default authentication information (username = root ) (password = nosoup4u)
= Accessing SheevaPlug serial console from a Linux box =
== # Connect the device using the mini USB -> USB cable.# You will find a new /dev/ttyUSBx device (/dev/ttyUSB0 if there are no other USB serial ports).# Connect to this port using the cu command (found in the '''Installing F12 on an SD and booting from the SheevaPlug'uucp'' ==package): cu -l ttyUSB0 -s 115200
[= Installing F12 on an SD = # Plug an ethernet cable into the SheevaPlug and connect it to your router.# Check the DHCP table on the router to find out the IP that was assigned to the SheevaPlug (i.e. 192.168.15.109)# <code>ssh root@''ipaddress''</code> (i.e. 192.168.15.109)# Insert the SD card into the SheevaPlug's card reader slot.# <code>dmesg | tail</code> (shows the mount point) (i.e. /dev/mmc1)# Partition the SD card using <code>fdisk /dev/mmc1</code> (Delete any existing partitions)# Create a new partition (C) accept the defaults, make it bootable (a), verify it (p) and write the new partition table (w)# Create the file system using mkfs.ext3 /dev/mmc1# Get the Kernel: <code>wget http://ftp.linux.org.uk/pub/linux/arm/fedora/platforms/sheevaplug/uImage-2.6.30-sheevaplug</code> and root filesystem <code>http://apvsbr700ftp.linux.org.uk/pub/linux/arm/fedora/rootfs/rootfs-f12.tar.bz2</code>#*NOTE: WGET may not be installed on the SheevaPlug so run "yum install wget"#*NOTE: If you are not connected to the internet run route add default gw <ip address> and add the name server to /etc/resolv.blogspotconf# Create a mount point using <code>mkdir /media/flash</code>.com Mount the SD card using <code>/dev/mmc1 /2010media/04flash</firstcode>. Uncompress the file system using <code>tar -jxf rootfs-attemptf12.tar.bz2</code>. Copy the filesystem over to the SD card using <code>cp -atr rootfs-f12/* /media/flash</code>. Copy the the kernel over to the SD card using <code>cp uImage-2.6.30-installsheevaplug/media/flash/boot</code> = Booting F12(on the SD) from SheevaPlug = In order boot from the SD card, u-boot must be configured. Depending onwhat version of u-sdboot you have, you might have to take an extra step in upgrading u-cardboot. Use the link below for the upgrade procedures. [[http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.htmlHow-TO on Upgrading U-Boot]] If you have the newest version or have finished upgrading continue to the following steps: # Reboot the SheevaPlug, and during the countdown, interrupt it by pressing any key.# Run the following commands:#* Marvell>> setenv mainlineLinux yes#* Marvell>> setenv arcNumber 2097#* Marvell>> setenv bootargs_console console=ttyS0,115200#* Marvell>> setenv bootargs_root 'rw root=/dev/mmcblk0p1 rootdelay=10 rootfstype=ext2'#* Marvell>> setenv bootcmd_mmc 'mmcinit; ext2load mmc 0 0x800000 /boot/uImage-2.6.30-sheevaplug'#* Marvell>> setenv bootcmd 'setenv bootargs $(bootargs_console) $(bootargs_root); run bootcmd_mmc; bootm 0x0800000'#* Marvell>> saveenv#* Marvell>> reset# Once the device reboots, you should be prompted with the fedora-arm login.
