This page covers installation of Ubuntu "Lucid" 10.04 on Marvell Dove X0 boards. Dove Y0/Y1 boards are not supported anymore.
== Known issues ==
Please consult the [[ARM/LucidReleaseNotes|known issues with Ubuntu 10.04 ARM platforms]] before installing.
== Preparation and image writing ==
==== Prep Work ====
u-boot requires a TFTP server to download files from. Several are available in universe, including attpd and tftpd-hpa. Install the server on a machine the Dove can access and take note of its IP address.
==== Update the BootROM ====
All Marvell boards have a BootROM written both in physical ROM, and a small section of SPI that can be used for upgrades. Newest versions of Marvell's kernel requires a newer BootROM, with the newest being 2.04. All X0 boards should ship with BootROM 2.04; if not, you need to upgrade the bootROM to at least 2.04:
* BootROM 2.04: http://people.canonical.com/~mcasadevall/dove/dove_bootrom_2_04_spi_0x1.img
Take that file, and place it in the TFTP folder. In addition, please make sure your board is setup for SPI booting (detailed below). At the u-boot prompt, type the following commands:
{{{
Marvell>> setenv serverip *ip address of TFTP server*
Marvell>> setenv ipaddr *board IP address*
Marvell>> tftp 2000000 dove_bootrom_2_04_spi_0x1.img
Marvell>> protect off f87f0000 f8800000
Marvell>> erase f87f0000 f8800000
Marvell>> cp.b 2000000 f87f0000 10000
Marvell>> protect on f87f0000 f8800000
Marvell>> reset
}}}
If successful, the board will boot back into u-boot. Depending on the version of u-boot in SPI, it may or may not print a message about the new BootROM in SPI. These messages look like the following:
{{{
BootROM version (on chip)= 1.07
BootROM version (upgrade on SPI)= 2.04
BootROM Status:
Number of retries = 0
}}}
==== Update u-boot ====
The stock u-boot on the Marvell Dove X0 board is sufficient to boot Ubuntu, and this step is optional. However, bugs related to suspend and resume were fixed with u-boot 4.4.2, and it is highly recommended that you upgrade.
Canonical versions have a version string similar this
{{{
U-Boot 1.3.4 (Oct 15 2009 - 12:11:45) Marvell version: 4.3.0 NQ - SPI BOOT. Canonical Development Version.
}}}
The current recommend version of u-boot for dove is Marvell-4.4.2
If your u-boot is older, you'll have to update it to a newer version. u-boot binaries for X0 are located here: http://people.canonical.com/~mcasadevall/dove/. The date of the binary is at the end of each filename in MMDDYYYY format. Official binaries from Marvell end in Marvell-VERSION. The filename also includes where the u-boot is supposed to be installed to, and the amount of RAM the board should have; MAKE SURE THESE VALUES ARE CORRECT; flashing a bootloader which doesn't match the hardware revision or amount of RAM may prevent the board from powering up and requiring UART recovery.
/!\ '''DANGER - If you are at all unsure, please confirm what you are doing is correct with NCommander; a bad u-boot flash WILL brick your board without a JTAG adapter'''<

Make sure that the serverip and ipaddr variables are properly set in u-boot (use printenv *name* to check, setenv *name* *value* to change, and save to commit). If you can currently TFTP images to your board, these values are correct.
The bubt command is used for upgrading u-boot on the same medium (i.e., flashing a new u-boot to SPI while booted from SPI). It can't be used to go from one boot medium to another (i.e., SPI to NAND).
{{{
Marvell>> setenv serverip ''TFTP Server''
Marvell>> setenv ipaddr ''board IP address''
Marvell>> bubt ''filename of uboot''
}}}
Answer yes when asked if you wipe the environmental variables. Type reset when done to boot into the new u-boot
==== Writing the Image ====
First of all you need to download the [[http://cdimage.ubuntu.com/ports/daily-live|Image]] to a large enough USB stick (1GB will suffice) that u-boot will be able to use; !SanDisk were reported as supported.
For writing the image either use the usb-imagewriter tool which you can install from the Jaunty universe archive (packages for [[https://launchpad.net/%7Eogra/+archive/ppa/+files/usb-imagewriter_0.1.2-0ubuntu1~hardy~ppa1_all.deb|Hardy (8.04)]] and [[https://launchpad.net/%7Eogra/+archive/ppa/+files/usb-imagewriter_0.1.2-0ubuntu1~intrepid~ppa1_all.deb|Intrepid (8.10)]] can be found at the [[https://launchpad.net/~ogra/+archive/ppa|usb-imagewriter PPA]]) or follow the commandline method below.
{{{
sudo dd bs=4M if=./lucid-desktop-armel+dove.img of=/dev/sdb
}}}
(assuming your USB stick is called /dev/sdb)
You'll also need a SATA disk or large USB harddrive as the target installation device.
/!\ USB booting is supported, but the Dove bootloader is extremely picky on what devices it will boot from. Using SATA is recommended and perferred
== Starting the live system manually ==
/!\ These instructions are currently for reference if you need to manually start from the boot prompt. Current u-boot versions will autostart from a properly written USB stick
Attach the USB pendrive you made in the previous step to the Dove, and then reset the board with the drive attached.
'''IMPORTANT''' - Don't type usb start more than once in any given u-boot session since it will cause u-boot to loose track of all devices it currently sees.
You can test if the drive was detected like this:
{{{
Marvell>> usb start
(Re)start USB...
USB: scanning bus for devices... 2 USB Device(s) found
scanning bus for storage devices... 1 Storage Device(s) found
Marvell>> fatls usb 0:1

}}}
If you get file output, your in business. The live image can be started with the following if you have the hush shell available.
{{{

If your using a non-hush enabled u-boot, you will have to load the uImage and uInitrd by hand to start the live environment
