‎Required system changes

New page

== Prepare installation media ==
* Create bootable LiveUSB using [http://cdimage.ubuntu.com/ports/releases/lucid/release/ubuntu-10.04-server-armel+dove.img Marvell Dove server install image]. Please refer to [http://help.ubuntu.com/community/Installation/FromImgFiles Installation From Img Files] for description of Ubuntu Live USB images.
* Replace {{filename|cdrom/uImage}} file on LiveUSB with [http://compulab.co.il/workspace/sw/ubuntu/lucid/files/uImage uImage] file provided by Compulab.
* Ensure {{filename|uImage}} file integrity, compare its md5sum with [http://compulab.co.il/workspace/sw/ubuntu/lucid/files/uImage.md5 uImage.md5]

== Installation of generic Ubuntu 10.04 Server==
* Connect the host PC to the CM-A510 via the serial cable supplied with the CM-A510 evaluation kit.
* Start terminal emulation software on your PC using the COM port to which the serial cable is connected. Set baud rate to 115200 bps, 8 bit per frame, 1 stop bit, no parity, no flow control.
* Connect LAN0 Ethernet port on CM-A510 (connector P11 on SB-A510) to your local Ethernet.
* Connect LiveUSB to L11 USB port on CM-A510 (connector P11 on SB-A510).
* Connect storage media to the SATA port (connector P18 on SB-A510).
* Turn on the CM-A510. The U-Boot boot-loader will start and you will get a command prompt.
*: {{Note|If the boot settings of your CM-A510 are different than default, you may need to press and hold ^C while turning on the CM-A510, in order to get command prompt.}}
* Start the U-Boot USB subsystem, check that your LiveUSB has valid filesystem and boot.
usb start
fatls usb 0
fatload usb 0:1 0x00200000 /cdrom/uImage
fatload usb 0:1 0x01100000 /cdrom/uInitrd
setenv bootargs pm_disable console=ttyS0,115200 file=/cdrom/preseed/ubuntu-server.seed cdrom-detect/try-usb=true
bootm 0x00200000 0x01100000''

* The resulting output should be similar to the following:

* Continue standard Ubuntu Server installation - choose timezone, partitions, username, password etc.
** Choose language, country, territory or area and keyboard layout
** Say ''"Yes"'' when asked "Continue the install without loading kernel modules?"
** Choose primary network interface, timezone and hostname
** Choose manual partitioning method.
** Make separate partition for {{filename|/boot}} with ext2 or ext3 filesystem. It is essential because U-Boot is able to read {{filename|uImage}} file only from the root directory of a partition.
** Make separate partitions for {{filename|/}} and swap.
** For example use the following scheme:
<pre>
SCSI1 (0,0,0) (sda) - 160.0 GB ATA Hitachi HTS54321
> #1 primary 100.0 MB F ext2 /boot
> #2 primary 158.9 GB F ext4 /
> #3 primary 1.0 GB F swap swap
</pre>
: {{Note|If your partitioning scheme is different, you may need to edit U-Boot boot parameters accordingly.}}
* Write changes to disk and continue installing the system.
** Say ''"Yes"'' when asked "Continue without installing a kernel?"
** Choose username, password and wait until installation will be finished.
** Reboot the CM-A510, leave LiveUSB plugged in the USB port.
** The U-Boot boot-loader will start and you will get a command prompt.
* After the reboot
