It is basically a Plug Computer, with the following specs:
My goal is to put Arch Linux on it. It seems that no one has done this yet.
What I am going to do, is set-up the system with Debian, which boots from the hard disk. There a number of recipes around to do this, particularly on the openstora.com site. I am following this one http://www.openstora.com/phpBB3/viewtopic.php?t=217
It did not contain all the information, so I thought about writing this walk through and fill in some blanks.
What you need to start is a USB serial cable. I got a Nokia phone data cable from eBay for a few Euros. Cut the end off the cable and solder some header thing on it. I used and old PC motherboard cable that I chopped up.
You also need some method to access the disk as a USB device. I used an old dismantled external drive controller board, which was handy.
To remove the back panel, you need to remove the two screws behind the Disk Release Latches. There are two of those nasty plastic clips about 5cm in from each side. There are two more of these nasty fellas about 9cm down from the top on the left and right side. Gently prise the panel with a small screw driver and it should pop off. Pop it off from the top as there are two clips on the bottom of the panel. These can be seen when looking at the bottom of the case.
You can see the serial port pins at the top of the board.
The pin-outs are from right to left:
Pin Function Notes
1 3.3Vdc Pin is the farthest from the battery.
2 RXD Recieve Data line from Stora.
3 TXD Transmit Data line from Stora.
4 GND Ground.
I will be using 2, 3 and 4, as I have cable made from an old Nokia USB data cable.
I installed tftp-hpa on the laptop, as the tftp server.
Connect stora to real network
Set-up environment for flashing.
setenv mainlineLinux yes setenv arcNumber 2743 setenv ipaddr XXX.XXX.XXX.XXX #This is the IP of your Stora setenv serverip XXX.XXX.XXX.XXX #This is the IP of your TFTP server saveenv reset
The install the files from your tftp server
tftpboot 0x200000 uImage.di
tftpboot 0x800000 uInitrd.di
setenv bootargs console=ttyS0,115200n8 base-installer/initramfs-tools/driver-policy=most
bootm 0x200000 0x800000This will install Debian to the hard disk.
The disk partitioning takes a long time, 40 minutes or so, so go and have a cup of tea or a beer. I wouldn't recommend reboot at this time, cuz I don't know what state the Stora would be in. Perhaps and expensive brick.
Then, it begins installing the system..............
I then followed the remaining instructions on http://www.openstora.com/phpBB3/viewtopic.php?t=217
I got quite a few errors but kept going.
Presto chango! Debian!
aka FAIL
It wouldn't boot. Feck again.
I scrolled down further on that page and began to experiment a bit with the settings.
setenv bootcmd_ide 'ide reset; ext2load ide 0 0x200000 /boot/uImage; ext2load ide 0 0x800000 /boot/uInitrd'
setenv bootcmd 'setenv bootargs $(console) root=/dev/sda1; run bootcmd_ide; bootm 0x200000 0x800000'
saveenv
reset
Again FAIL. Again Feck.
I took out the drive and connected it via USB to my laptop.
I ended up with a single partition that had some GPT data in the partition table
# fdisk -l /dev/sdb
WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk
doesn't support GPT. Use GNU Parted.
Feck again.
I used this link to remove it http://www.rodsbooks.com/gdisk/wipegpt.html
All cool.
Install Arch Linux
My next plan, was to prepare the disk and put an arm version of Arch Linux on it.
What you need is, the board ot whatever to connect your SATA drive to a USB cable. Connect it up.
Mine was /dev/sdb
Partition New Disk
I wanted to have the following disk layout:
/dev/sdb1 = 2Gb plenty of space. I don't want to have to worry that it will fill up and require maintenance at a later date.
/dev/sdb2 = swap of 1Gb
/dev/sdb3 = The rest of the disk
I have taken out some of the disk detail because it just clutters up the page.
> fdisk /dev/sdb
Delete whatever partitions are on the disk.

The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
Done
Set-up the file systems and install Arch and Kernel files
I wanted to have journeling so I setup /dev/sdb1 to ext3. It should be reognised as ext2 on boot.
mkfs.ext3 /dev/sdb1
mkfs.ext4 /dev/sdb3
Mount /dev/sdb1 and cd to the mount point
wget http://archlinuxarm.org/os/ArchLinuxARM-armv5te-latest.tar.gz
extract the Arch linux tarball to the root of /dev/sdb1
e.g.
tar zxvf /location/ArchLinuxARM-armv5te-latest.tar.gz
kernel image: http://dl.dropbox.com/u/1397036/stora_di/uImage
initrd image: http://dl.dropbox.com/u/1397036/stora_di/uInitrd
wget the images and copy them into the boot directory of /dev/sdb1
Almost complete.
Finally put the disk back in the stora in the left slot.
Boot into the uBoot prompt.
Here are the settings I found that worked.
setenv mainlineLinux yes
setenv arcNumber 2743
setenv bootcmd_ide 'ide reset; ext2load ide 0 0x200000 /boot/uImage; ext2load ide 0 0x800000 /boot/uInitrd'
setenv bootcmd 'setenv bootargs $(console) root=/dev/sda1; run bootcmd_ide; bootm 0x200000 0x800000'
saveenv
reset
Let it run and it should boot into Arch Linux.
Woo Hoo !!!
Restore Original Firmware
It seems that the original firmware is stilled in Nand. To restore this use the following:
setenv mainlineLinux=no
setenv arcNumber
setenv bootcmd_ide
setenv bootcmd 'nand read.e 0x800000 0x100000 0x300000; setenv bootargs $(console) $(bootargs_root); bootm 0x800000'
saveenv
reset
Back to Arch Linux
setenv mainlineLinux yes
setenv arcNumber 2743
setenv bootcmd_ide 'ide reset; ext2load ide 0 0x200000 /boot/uImage; ext2load ide 0 0x800000 /boot/uInitrd'
setenv bootcmd 'setenv bootargs $(console) root=/dev/sda1; run bootcmd_ide; bootm 0x200000 0x800000'
saveenv
reset
The End
Now to put it back together, set it up with the services I want and put it into production as a house file server and some other sneaky things.
