3 Procedure

3.1 Grabbing the serial port

First you need to connecto to the serial port. For this purpose you use an Arduino style level shifter with 3,3V which you connect to the pins 6, 4, 2:

 9  7  5  3  1 
10  8  6  4  2
      RX TX GND 3.3V!

Now do the following steps:

Connect the Freeagent to your DHCP router, but don't connect it to the internet! The Freeagent shall receive an IP address, but it shall not be able to phone home!
Start your terminal client (Linux: minicom), and don't forget to disable Hardware Flow Control in minicom!!

So when you now boot up the device, you'll get the following output in the terminal:

U-Boot 1.1.4 (Jul 16 2009 - 21:02:16) Cloud Engines (3.4.16)

So my Freeagent has received the IP 192.168.178.24

3.2 Logging in through the network

You may also find out its address if you look at the router GUI or if you use

fping -g 192.168.0.0/24

So when you know the IP, you can now log into the Freeagent using

ssh root@(Freeagent-IP)
Passwd: stxadmin

If you have plugged in a USB stick, you may see it with mount:

-bash-3.2# mount 
 rootfs on / type rootfs (rw) 
 /dev/root on / type jffs2 (ro) 
 none on /proc type proc (rw) 
 none on /sys type sysfs (rw) 
 none on /dev/pts type devpts (rw) 
 none on /tmp type tmpfs (rw) 
 /tmp/.cemnt/sda1 on /tmp/.cemnt/mnt_sda1 type ext2 (rw,nosuid,nodev,noexec,noatime)

sda1 is a hard drive. 'cd' into it and back up the NAND:

-bash-3.2# cd /tmp/.cemnt/mnt_sda1

-bash-3.2# mkdir Backup 
-bash-3.2# cd Backup

-bash-3.2# dd if=/dev/mtd0 of=mtd0 
   2048+0 records in 2048+0 records out 
-bash-3.2# sha1sum mtd0 >mtd0.sha1
-bash-3.2# dd if=/dev/mtd1 of=mtd1 
   8192+0 records in 8192+0 records out 
-bash-3.2# sha1sum mtd1 >mtd1.sha1 
-bash-3.2# dd if=/dev/mtd2 of=mtd2 
   65536+0 records in 65536+0 records out 
-bash-3.2# sha1sum mtd2 >mtd2.sha1 
-bash-3.2# dd if=/dev/mtd3 of=mtd3 
   448512+0 records in 448512+0 records out 
-bash-3.2# sha1sum mtd3 >mtd3.sha1

3.3 Resume control

Now we want to resume control and make sure that the Pogoplug software won't call home.

-bash-3.2# killall hbwd                      #stop the Pogoplug binary
-bash-3.2# mount -o remount,rw /             #remount writeable
-bash-3.2# chmod go+w /dev/null              #fix a bug

Disable the pogoplug code to come up again when the system starts up the next time:

-bash-3.2# vi /etc/init.d/rcS

Now go to the line that says

/etc/init.d/hbmgr.sh start

and disable it by writing a "#" in front.

Now you can reboot with

-bash-3.2# mount -o remount,ro / 
-bash-3.2# /sbin/halt

3.4 Prepare the installation

The method with Jeff Doozan's script did not work for me because the repository seemed corrupted. The steps were taken from there: http://www.mikrocontroller.net/articles/DockstarDebianSqueeze#Debian_installieren

So I tried the TFTP method: http://www.plugcomputer.org/plugwiki/index.php/Installing_Debian_To_Flash#Run_the_Debian_Installer

First you need to install atftpd: http://www.ubuntugeek.com/howto-setup-advanced-tftp-server-in-ubuntu.html

Note that the default tftp-directory is /srv/tftp

Then follow the advice given there: http://www.plugcomputer.org/plugwiki/index.php/Installing_Debian_To_Flash#Fetch_the_bits and get the following files:

3.4.1 U-Boot Images

DENX U-Boot is recommended over the old, buggy Marvell version. Instructions re. upgrading are below.

3.4.2 Debian Installer

The latest installer images should be available at:

http://d-i.debian.org/daily-images/armel/daily/kirkwood/netboot/marvell/sheevaplug/

however, if the automated build fails, the above may not exist; in which case look for the last successful build in

http://d-i.debian.org/daily-images/armel/

For example, if at the time of writing (2011-06-02) the current build was missing, the last successful image could be:

http://d-i.debian.org/daily-images/armel/20110527-16:34/kirkwood/netboot/marvell/sheevaplug/

The above are the daily images, used for testing; if you prefer, you can find the latest stable images here:

ftp://ftp.debian.org/debian/dists/stable/main/installer-armel/current/images/kirkwood/netboot/marvell/sheevaplug/

You want both the uImage and uInitrd files. Into the TFTP directory they go.

3.4.3 Kernel

http://sheeva.with-linux.com/sheeva/ - what more is there to say? Oh, except that you probably want the latest, and you definitely want the sheeva-2.6.XX-uImage and sheeva-2.6.XX-Modules.tar.gz files. The config file might be good too, if you want to see what kernel config you're running with. Put 'em all in the TFTP directory.

3.5 Updating U-Boot

Follow the instructions given here: http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html

In order to do this, you need to get the TFTP server working on your desktop machine. Then get the u-boot image from: http://people.debian.org/~tbm/u-boot/2011.03-6/dockstar/u-boot.kwb

Then in the serial console enter these commands:

setenv serverip 192.168.1.2 # IP of your TFTP server
setenv ipaddr 192.168.1.200
tftpboot 0x0800000 u-boot.kwb
nand erase 0x0 0x60000
nand write 0x0800000 0x0 0x60000

then reboot with

resume.

AND DO NOT UNPLUG POWER!!!!!!!!!!!!

The bootup should look line this:

Marvell>> reset
resetting ...

3.6 Do the installation

You need to do these steps over the serial console:

setenv ipaddr 192.168.178.24
setenv serverip 192.168.178.52
tftpboot 0x2000000 uImage
tftpboot 0x0800000 uInitrd
setenv bootargs console=ttyS0,115200 base-installer/initramfs-tools/driver-policy=most
bootm 0x2000000 0x0800000

This gets the installer and starts it with a reboot. Then go through all the steps as guided.

Note the installation will take A VERY LONG TIME!!!
Note, the installation will require some interaction!

3.6.1 Important Hints

When prompted, set the following:

Partitioning: Use the entire disk (default setting). This will make it easier to write the image to the NAND, if you wish so. Yet, it will be hard, especially if your image is very big.

3.7 Burn the kernel image

Now a kernel is missing. First check the environment because the variables, especially the mtd partitioning is highly important now. This is how it should be! (works for me)

baudrate=115200
bootargs=console=ttyS0,115200 mtdparts=nand_mtd:0xa0000@0x0(u-boot),0x400000@0x100000(uImage) root=/dev/sda2 rootwait rw
bootargs_root=ubi.mtd=1 root=ubi0:root rootfstype=ubifs ro
bootcmd=nand read 0x100000 uImage; bootm 0x100000
bootdelay=3
console=console=ttyS0,115200
ethact=egiga0
ethaddr=02:50:43:5d:f2:96
fileaddr=2000000
filesize=2BB6E4
initrd=/boot/uInitrd
ipaddr=192.168.178.24
kernel=/boot/uImage
led_error=orange blinking
led_exit=green off
led_init=green blinking
mainlineLinux=yes
mtddevname=u-boot
mtddevnum=0
mtdids=nand0=orion_nand
mtdparts=mtdparts=orion_nand:1M(u-boot),4M(uImage)
partition=nand0,0
serverip=192.168.178.52
stderr=serial
stdin=serial
stdout=serial

The command mtdparts says this:

DockStar> mtdparts 

device nand0 <orion_nand>, # parts = 2
 #: name                size            offset          mask_flags
 0: u-boot              0x00100000      0x00000000      0
 1: uImage              0x00400000      0x00100000      0

active partition: nand0,0 - (u-boot) 0x00100000 @ 0x00000000

defaults:
mtdids  : none
mtdparts: none
DockStar>

Please note that the uImage partition should have this name and it should be 4M in size. This is important in order to make the booting possible! If the u-boot comes up with weird errors, check the partitioning! I hit the scenario when the uBoot would forget the kernel I burned before or tell me that it didn't have the correct CRC number.

Now it's necessary to provide the kernel in the tftp directory and load it via tftp:

setenv ipaddr 192.168.178.24
setenv serverip 192.168.178.52
tftpboot 0x800000 uImage

Here's my command:

DockStar> tftpboot 0x2000000 sheeva-3.0.9-uImage
Using egiga0 device
TFTP from server 192.168.178.52; our IP address is 192.168.178.24
Filename 'uImage'.
Load address: 0x800000
Loading: #################################################################
         #################################################################
         #################################################################
         #
done
Bytes transferred = 2864868 (2bb6e4 hex)
DockStar>

nand erase 0x100000 0x400000

flatten everything at 0x100000!

nand write 0x2000000 0x100000 0x400000

read from 0x2000000, write 0x400000 bytes to the address 0x100000

setenv bootargs 'console=ttyS0,115200 mtdparts=nand_mtd:0xa0000@0x0(u-boot),0x400000@0x100000(uImage) root=/dev/sda2 rootwait rw'
setenv bootcmd 'nand read 0x100000 uImage; bootm 0x100000'
setenv bootargs_root 'ubi.mtd=1 root=ubi0:root rootfstype=ubifs ro'
saveenv

That should be it.

Now you also need the modules, but not during the kernel boot process, but later when the system starts. As soon as you can log into your Freeagent installation, copy them over to the Freeagent and unpack them to /lib/modules:

dockstar $ tar xvfz sheeva-3.0.9-Modules.tar.gz -C /

Note: If you chose the most recent kernel that comes with the most recent installer, this step is not necessary, because the most recent kernel's modules come with the installer.
Note: The kernel may be updated from within the running system when you install the initramfs-tools

Please note that the memory sections in my example differ from that of other instructions you find around the web. I got a memory error and some weird system behaviour with these examples. So I decided to use some other memory segment at around 0x2000000. There's enough memory around, the NAND has 256MB. Since I don't intend to squeeze the rootfs into RAM first of all, there's plenty of space.

3.8 Write the image to the FLASH

My image is 622 MB, so it won't fit into the NAND.

If you manage to shrink the image to below 256M (which is the NAND size), you will be successful!

Follow the instructions here: http://www.plugcomputer.org/plugwiki/index.php/Installing_Debian_To_Flash#Convert_internal_flash_root_partition_to_UBIFS

3.9 Configure Debian

This comes from here: http://www.mikrocontroller.net/articles/DockstarDebianSqueeze

You surely want wo install the following tools:

apt-get install ntpdate

Set the system time:

dockstar $ ntpdate ntp1.ptb.de

apt-get install busybox-syslogd
apt-get install usbmount
apt-get install cron

Add a few lines to crontab:

dockstar $ crontab -e
*/30 * * * * /usr/sbin/ntpdate ntp1.ptb.de >> /var/log/ntpdate.log 2>&1
@reboot /usr/sbin/openntpd -s

WARNING: DO NOT INSTALL usbmount! It will mount the USB memory stick before the fsck and this will break your boot process, requiring manual interaction. Without a serial console, you're locked out!
