| - | |||
| - | Sources are available in the [[http:// | ||
| - | |||
| - | * **stable** is used to build the images distributed via a [[ftp:// | ||
| - | * **master** is a development branch, holding the patches waiting to be merged mainline. | ||

| - | Checkout command: | ||
| - | |||
| - | git clone http:// | ||
| - | or | ||
| - | git clone git:// | ||
| - | |||
| - | ===== Build ===== | ||
| - | |||
| - | To compile U-Boot images, you could use the following commands (toolchain path, cross-compiler and board names to be replaced): | ||

| - | ===== Downloads ===== | ||
| - | |||
| - | For the supported boards, some pre-compiled U-Boot images are availables in the [[ftp:// | ||
| - | |||
| - | ===== Install from a LaCie stock U-Boot ===== | ||
| - | |||
| - | ==== Why ? ==== | ||
| - | |||
| - | * 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, | ||
| - | |||
| - | * 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: | ||
| - | |||
| - | * Be able to add a new feature. | ||
| - | |||
| - | ==== Update step by step ==== | ||
| - | |||
| - | This section present step by step how to update the stock U-Boot with a mainline version. A Network Space v2 board is used but the process should work with all the other LaCie boards supported by U-Boot mainline. | ||
| - | |||
| - | === Preparations === | ||
| - | |||
| - | * Create a work directory | ||
| - | |||
| - | $ mkdir /tmp/tools && cd /tmp/tools | ||
| - | |||
| - | * Get [[CLUNC|CLUNC]] | ||
| - | |||
| - | $ wget ftp:// | ||
| - | $ tar xf clunc-1.1.tar.gz | ||
| - | |||
| - | * Get U-Boot **netconsole** utility | ||
| - | |||
| - | $ wget ftp:// | ||
| - | $ tar xf u-boot-netconsole.tar.gz | ||
| - | |||
| - | * Setup and enable a TFTP server. The configuration really depends on your OS. For example, a Linux distribution could be use **inetd** (the configuration file is / | ||
| - | |||
| - | * Install the new u-boot image into the TFTP root directory (could be / | ||
| - | |||
| - | $ wget ftp:// | ||
| - | | ||
| - | === Run CLUNC and connect to the LaCie U-Boot console === | ||
| - | |||
| - | 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 it is cheaper. The user don't have to build/buy a serial cable. | ||

| - | $ ./clunc -i < | ||

| - | | ||
| - | === Retrieve the NAS IP address === | ||
| - | |||
| - | U-Boot mainline don't provide a magic packet mechanism to configure the IP address. Instead DHCP is used. It means that [[CLUNC|CLUNC]] becomes useless from this point. | ||
| - | |||
| - | Some possible ways to retrieve the NAS IP address: | ||
| - | |||
| - | * Use an utility like **dhcpdump**. | ||
| - | * Look in the DHCP server log. | ||
| - | * Configure and run your own DHCP server. | ||
| - | |||
| - | === Connect to U-Boot via netconsole === | ||
| - | |||
| - | The netconsole configuration rely on some environment variables: **ipaddr**, **ncip**, **stdin**, **stdout** and **stderr** (for more information, | ||
| - | |||
| - | <note important> | ||
| - | **netcat** don't handle the UDP broadcast messages. The dedicated U-Boot tools **netconsole** and **ncb** must be used. | ||
| - | </ | ||
| - | |||
| - | * Run **netconsole** and interrupt boot process (Ctrl-C): | ||
