The Orion family of SoCs includes the following machines:

• Buffalo/Revolution Kurbox Pro
• Buffalo/Revolution Linkstation Mini
• Buffalo/Revolution Terastation Pro II/Live
• Lacie ED Mini V2
• Lacie Internet Space V1 (V2 uses kirkwood)
• Lacie 2Big
• Lacie 5Big
• Lacie d2 Network
• Lacie Big Disk Network
• Marvell Orion-2 Development Board, Marvell Orion-VoIP FXO, Marvell Orion-VoIP GE, Marvell Orion-NAS Reference Design, Marvell Orion-1-90 AP GE Reference Design
• Maxtor Shared Storage II
• QNAP TS-109/TS-209
• QNAP TS-409
• Technologic Systems TS-78xx

Sources are available in the Git repository: u-boot-lacie.git. At least, the following branches should be availables:

• stable is used to build the images distributed via a FTP repository.
• master is a development branch, holding the patches waiting to be merged mainline.

Checkout command:

git clone http://git.lacie-nas.org/u-boot-lacie.git

or

git clone git://lacie-nas.org/u-boot-lacie.git

To compile U-Boot images, you could use the following commands (toolchain path, cross-compiler and board names to be replaced):

PATH=/usr/local/x-tools/arm-2010q1/bin/:$PATH CROSS_COMPILE=arm-none-eabi- make netspace_v2_config
PATH=/usr/local/x-tools/arm-2010q1/bin/:$PATH CROSS_COMPILE=arm-none-eabi- make u-boot.kwb

For the supported boards, some pre-compiled U-Boot images are availables in the FTP repository.

• The LaCie stock U-Boot comes with a huge limitation. At reset, U-Boot reinitialize the boot environment variables (stored in Flash) with some built-in values. This includes the boot commands sequence. As a consequence, the LaCie system layout (or partition map) can't be changed. By default, U-Boot will load the Linux kernel from partition 10 (update) or from partition 6 as a fallback (default).

• Save flash size (a LaCie U-Boot image size is ~450KB against ~230KB for a mainline one).

• Boot reliably from USB.

• Some command line enhancements: history, completion, scripting …

• Be able to add a new feature.

This section present step by step how to update the stock U-Boot with a mainline version. Both a serial or a network console can be used to connect to U-Boot. For this how-to, the netconsole way is preferred because the user don't have to build/buy a serial cable.

• Get CLUNC
• Get U-Boot netconsole utility
• Enable a TFTP server
• Install the new u-boot image in the TFTP root directory (could be /var/tftpboot).

$ wget ftp://ftp.lacie-nas.org/u-boot/u-boot-netspace_v2.kwb -O /var/tftpboot/u-boot-netspace_v2.kwb

$ ./clunc -i <NAS_IP>

• Install the U-Boot netconsole tool.

Note that U-Boot mainline don't provide a magic packet mechanism to configure the IP address. It means that CLUNC becomes useless from this point. The netconsole configuration rely on some environment variables: ipaddr, ncip, stdin, stdout and stderr (for more information, please refer to the file README.NetConsole included in U-Boot sources). After the update, this variables will be initialized with the default (or built-in) values: the IP address is 192.168.1.111 and the netconsole is configured to broadcast messages. As a consequence, the server IP must belong to the subnetwork 192.168.1.0. Moreover netcat don't handle the broadcast messages. Instead, the U-Boot tools netconsole and ncb must be used.

• Connect to U-Boot via netconsole and interrupt boot process (Ctrl-C).

$ ./tools/netconsole 192.168.1.111
