 ====== Sheevaplug ==
+Installation of Slackware on a Sheevaplug with MMCard
+===== Where to buy ==
+http://www.sheevaplug.de/links/16-europaeische-bezugsquellen.html
 ===== Login ==
 To log in you need either a DHCP server for SSH or you have to set up a serial connection. These and everyting necessary described [[http://www.openplug.org/plugwiki/index.php/New_Plugger_How_To|here]]
+Default login is ''root / nosoup4u''
 ===== USB connection ==
-For me (on Slack12.2) it was necessary to ''modprobe ftdi_sio vendor=0x9e88 product=0x9e8f'' before a serial connection with seyon or minicom was possible. [[http://www.openplug.org/plugwiki/index.php/Serial_terminal_program|Source]]
+For me (on Slack 12.2 and 13.0) it was necessary to ''modprobe ftdi_sio vendor=0x9e88 product=0x9e8f'' before a serial connection with seyon or minicom was possible. [[http://www.openplug.org/plugwiki/index.php/Serial_terminal_program|Source]]
+After inserting the kernel module and powering on the Sheevaplug, ''/var/log/messages'' tells that 2 serial device files are created, eg. ''ttyUSB1'' and ''ttyUSB2''. One of them (probably the latter) ist for the serial terminal. Try both!
+Establish serial connection with eg: ''screen /dev/ttyUSB1 115200'' (and exit with ''Ctrl-a K''; see also: [[gnu screen]])
+===== MMC mount ==
+With the off the shelf Ubuntu a SD Card can be mounted on ''/dev/mmcblk0p1''. Note that ''/var/log/messages'' only reports ''/dev/mmcblk0''. You have to inspect the ''/dev'' directory to get the actual device.
 ===== Installing Slackware ==
-[[ftp://ftp.armedslack.org/armedslack/armedslack-13.1/INSTALL_KIRKWOOD.TXT|Source]]
+Source: [[http://mirror.inode.at/data/armedslack/armedslack-13.37/INSTALL_KIRKWOOD.TXT|INSTALL_KIRKWOOD.TXT]]
+Note that it is currently not possible to [[http://lists.armedslack.org/2009-September/000239.html|install Armed on the internal Sheeva NAND Flash]]. You need an MMCard or eSata card. (Used Trascend Ultimate 8GB SDHC Class10, 11,99€)
+==== Activate NFS ==
+<code bash>
+# add to /etc/exports:
+/home/export/armedslack 192.168.1.0/255.255.255.0(ro,nohide,root_squash,sync,no_subtree_check)
+</code>
+<code bash>
+# create directory to be exported:
+su
+mkdir -p /home/export/armedslack
+chmod g+w /home/export/armedslack
+chgrp users /home/export/armedslack
+# start NFS daemon:
+chmod +x /etc/rc.d/rc.rpc # check if this line is really necessary
+chmod +x /etc/rc.d/rc.nfsd
+/etc/rc.d/rc.nfsd restart
+</code>
+==== Setup TFTP boot server ==
+<code bash>
+# ucomment in /etc/inetd.conf:
+tftp  dgram   udp     wait    root    /usr/sbin/in.tftpd  in.tftpd -s /tftpboot -r blksize
+</code>
+<code bash>
+# create directory to be exported:
+su
+mkdir /tftpboot
+chmod g+w /tftpboot
+chgrp users /tftpboot
+# start inetd:
+chmod +x /etc/rc.d/rc.inetd
+/etc/rc.d/rc.inetd restart
+</code>
+==== Downloading Slackware ARM ==
+<code bash>
+cd /home/export/armedslack
+rsync --exclude '*/source/*' --delete -Pavv ftp.armedslack.org::armedslack/armedslack-13.37 .
+# or use a mirror:
+rsync --exclude '*/source/*' --delete -Pavv mirror.inode.at::mirror/armedslack/armedslack-13.37 .
+</code>
+This creates ''/home/export/armedslack/armedslack-13.37''.
+Other mirrors are listed in www.armedslack.org/getslack. Note that it is better to use rsync than FTP, because with rsync you can resume an aborted download with reusing already downloaded files.
+==== Populating the /tftpboot directory ==
+<code bash>
+mkdir /tftpboot/armedslack-13.37
+cd /home/export/armedslack/armedslack-13.37/
+# Copy the Slackware ARM installer:
+cp -fav isolinux/uinitrd-kirkwood.img /tftpboot/armedslack-13.37/
+# The Linux Kernel:
+cp -fav kernels/kirkwood/uImage* /tftpboot/armedslack-13.37/
+# The Initial RAM disk, used for booting the OS after installation
+cp -fav kernels/kirkwood/uinitrd* /tftpboot/armedslack-13.37/
+</code>
+Is an uboot update necessary? [[http://www.armedslack.org/maint_kirkwooduboot|Source]]
+  Marvell>> version
+  U-Boot 1.1.4 (Jul 14 2009 - 06:46:57) Marvell version: 3.4.16
+=> U-Boot version is ok, but Marvell version (whatever that is) is outdated FIXME
+==== Connecting to the Kirkwood system via the Serial Port ==
+A ''screen /dev/ttyUSB1 115200'' is sufficient for me, skipped this section in the source
+Log into the Sheevaplug as root and reboot the system. When the system comes up again, hit the enter key several times to get into Uboot.
+==== Configuring the Sheevaplug Uboot ==
+Get available uboot commands with ''help''. You can scroll in ''screen'' upward with ''Ctl-a ['' and then simply use the arrow keys. End scrolling with ''Ctl-a ]'' [[http://www.tutorials.de/linux-tutorials/151906-einfuehrung-screen.html|Source]]
+<code>
+Marvell>> printenv ipaddr
+ipaddr=10.4.50.165
+Marvell>> printenv serverip
+serverip=10.4.50.5
+Marvell>> printenv arcNumber
+## Error: "arcNumber" not defined
+Marvell>> printenv mainlineLinux
+mainlineLinux=no
+Marvell>> setenv ipaddr 192.168.0.99
+Marvell>> setenv serverip 192.168.0.7
+Marvell>> setenv arcNumber 2097
+Marvell>> setenv mainlineLinux yes
+Marvell>> saveenv
+Marvell>> reset
+</code>
+==== Slackware ARM installation ==
+Plug in the MMC card and type ''mmcinit'' (May not work the first time, so retry):
+<code>
+Marvell>> mmcinit
+SDHC found. Card desciption is:
+Manufacturer:       0x1b, OEM "SM"
+Product name:       "00000", revision 1.0
+Serial number:      1962687311
+Manufacturing date: 9/2010
+CRC:                0x00, b0 = 0
+</code>
+<code>
+Marvell>> tftpboot 0x01100000 armedslack-13.37/uinitrd-kirkwood.img
+Marvell>> tftpboot 0x00800000 armedslack-13.37/uImage-kirkwood
+Marvell>> printenv bootargs
+[empty]
+setenv bootargs console=ttyS0,115200 nodhcp kbd=de root=/dev/ram rw
+bootm 0x00800000 0x01100000
+</code>
+An animated loading sequence comes up. After the first 2 commands
+Note that keyboard was set to ''de''. Use your appropriate entry. After ''bootm ...'' the kernel gets uncompressed und you will see the welcome screen of the standard Slackware installation :-) Log in as root.
+<code>
+# Bring up network:
+# (a ping to the sheevaplug should work after this command)
+ifconfig eth0 192.168.0.99 netmask 255.255.255.0
+# start SSH daemon:
+/etc/rc.d/rc.dropbear start
+</code>
+Now you can log into the Sheevaplug with SSH as user root with no password: ''ssh root@192.168.0.99''. From here use the ssh, not the serial login.
+''fdisk -l'' shows your available drive: ''/dev/mmcblk0''. Use ''fdisk'' to partition the drive, cfdisk did not work:
+<code>
+fdisk /dev/mmcblk0
+</code>
+Unset DOS Compatibility flag and change display/entry units to sectors:
+<code>
+Command (m for help): c
+DOS Compatibility flag is not set
+Command (m for help): u
+Changing display/entry units to sectors
+</code>
+Now with fdisk delete the existing FAT32 partition and set up the following partitions (100MB for /boot, 800MB for swap, the rest for /):
+<code>
+Command (m for help): p
+Disk /dev/mmcblk0: 8011 MB, 8011120640 bytes
+...
+        Device Boot      Start         End      Blocks   Id  System
+/dev/mmcblk0p1            2048      206847      102400   83  Linux
+/dev/mmcblk0p2          206848     1845247      819200   82  Linux swap
+/dev/mmcblk0p3         1845248    15646719     6900736   83  Linux
+</code>
+Set the TERM varialble to linux (why?) and run Slack setup:
+  root@slackware:~# TERM=linux setup
+Because the following steps are very similar to a normal [[slack_setup_tips|Slack installation]], here only the key points:
+  * Keymap: qwertz/de-latin1-nodeadkeys.map
+  * Using ''/dev/mmcblk0p2'' as swap
+  * Using ''/dev/mmcblk0p3'' :!:  as ''/'' with ext4
+  * Using ''/dev/mmcblk0p1'' as ''/boot'' with ext2
+<note important>With armedslack-13.37, selection of ''ext2'' was ignored and the ''/boot'' was partition formattet with ''ext4'' anyway! Hence booting the system failed after install. Here is a workaround:
+  - Insert the MMCard into a Notbook after installation of armedslack has finished
+  - Save the contents of ''/dev/mmcblk0p1''
+  - Reformat ''/dev/mmcblk0p1'' with the notebook (''mkfs.ext2 /dev/mmcblk0p1'')
+  - Restore the contents of ''/dev/mmcblk0p1''
+</note>
+  * Install from NFS with ''/home/export/armedslack/armedslack-13.37/slackware'' as source
+  * Package selection: Everything except KDEI (=default); mode: full. Installation takes a long time.
+==== Booting the Slackware ARM OS ==
+Reboot the system with ''reboot'' and enter U-boot once again.
