= Goal =
To prepare the SheevaPlug, one of the [[Fedora ARM Secondary Architecture/ARM hardware|ARM systems]], so that it can be added to the Koji build pool. = SheevaPlug Specifications = == Sheeva CPU Core ==* 1.2 GHz operation* L1 Cache: 16K Instruction + 16K Data* L2 Cache: 256KB = = Memory ==* DDR2 400MHz, 16-bit bus, 512MB* NAND FLASH Controller, 8-bit bus, 512MB NAND FLASH* 128-bit eFuse Memory (for tiny, permanent storage, e.g., serial number) == Power == * Power input: 100-240VAC/50-60Hz 19W DC Consumption: 5V/3.0A* High efficiency POL DC-DC converters == Development Interface == * System Development Board JTAG and Console Interface via USB* SDIO expansion* JTAG OpenOCD support via USB == High Speed I/O & Peripherals ==* USB 2.0 Host* SD slot* RTC w/ Battery* Programmable LED == Hardware Links ==* [http://www.globalscaletechnologies.com/p-22-sheevaplug-dev-kit-us.aspx Manufacturer's product page] = 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 ''uucp''package): cu -l ttyUSB0 -s 115200 = Installing F12 on an SD = # Plug an ethernet cable into the SheevaPlug Specsand 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://ftp.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.conf# Create a mount point using <code>mkdir /media/flash</code>. Mount the SD card using <code>/dev/mmc1 /media/flash</code>. Uncompress the file system using <code>tar -jxf rootfs-f12.tar.bz2</code>. Copy the filesystem over to the SD card using <code>cp -r rootfs-f12/* /media/flash</code>. Copy the the kernel over to the SD card using <code>cp uImage-2.6.30-sheevaplug/media/flash/boot</code> = Booting F12(on the SD) from SheevaPlug = In order boot from the SD card, u-boot must be configured. Depending on what version of u-boot you have, you might have to take an extra step in upgrading u-boot. Use the link below for the upgrade procedures. [[http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html How-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. Login using "root" and the password is "fedoraarm"
