- <p>
- U-Boot is an open source bootloader ported to a multitude of processors.
- See (<a href="http://www.denx.de/wiki/U-Boot/WebHome">U-Boot Home</a>)
- for documentation for vanilla U-Boot. This document only describes
- changes compared to the vanilla u-boot.

-
- <p>
- "at91rm9200dk" is updated to use a linux like API for gpio.
- A new target "at91rm9200dk_df" is defined to support boot from dataflash.
- </p>

- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- The "at91rm9200ek" BSP supports booting from a parallel flash.
- The "at91rm9200df" BSP supports a generic target booting from dataflash.
- </p>

- <h2><a name="minicom_extensions" id="minicom_extensions"></a>Minicom extensions </h2>
- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- "sx-at91" is a reliable X-Modem application allowing download to the at91rm9200
- based board
- </p>
- <p>
- "raw-at91" is a download application which will download binary data using minicom.
- Typically used to download an environment script.

- <h2><a name="cmd_factory" id="cmd_factory"></a>New command: factory</h2>
- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- <h3><code>factory</code></h3>
- </p>
-
- <p>
- "factory" will set a selected set of environment variables
- back to the compile time default. The following will give some
- hints on capabilities, but is not yet complete.
- </p>
-
- <p>
- It will generate a set of scripts which will facilitate downloading
- the kernel and root file system using tftp and will also
- add commands to store into and retrieve from flash
- </p>
-
- <h2><a name="cmd_os" id="cmd_os"></a>New command: os</h2>
- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- <h3><code>os<code></h3>
- </p>
- <p>
- "os" computes a new name for the linux kernel
- </p>
-
- <h2><a name="cmd_fs" id="cmd_fs"></a>New command: fs</h2>
- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- <h3><code>fs<code></h3>
- </p>
- <p>
- "fs" computes a new name for the file system
- </p>
-
- <h2><a name="cmd_setargs" id="cmd_setargs"></a>New command: setargs</h2>
- <a href="#top"><small>[TOP]</small></a>
- <p>
- <h3><code>setargs<code></h3>
- </p>
- <p>
- "setargs" will create new bootcmd/bootargs combination from
- kernel name, filesystem name, and rootfs type.
- </p>
-
- <h2><a name="cmd_led" id="cmd_led"></a>New command: led</h2>
- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- <h3><code>led [green | yellow | red | all ] [ on | off ]<code></h3>
- </p>
-
- <p>
- "led" will turn on or off the specified (coloured) led
- </p>
-
- <h2><a name="cmd_mux" id="cmd_mux"></a>New command: mux</h2>
- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- <h3><code>mux [spi | mmc ]<code></h3>

- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- <h3><code>ethinit<code></h3>
- </p>
-
- <p>
- "ethinit" can be used to delay the boot of linux, until a valid network
- connection has been established. This is useful if the machine is NFS mounting
- the root file system and both this machine and the NFS server are powering up
- simultaneously. The NFS server could take a lot longer to boot, and waiting
- for this to boot may be neccessary for proper operation.
- </p>
-
- <h2><a name="environment" id="environment"></a>Special environment variables</h2>
- <a href="#top"><small>[TOP]</small></a>
-
- <p>
- <h3><code>rd<code></h3>
- </p>
- <p>
- rd contains the name of the current root file system
- It is autmatically generated from <bold>ver</bold> and <bold>rd-1</bold>, <bold>rd-2</bold> etc.
- The "fs-date" is added at the end.
- </p>
-
- <p>
- <h3><code>ver<code></h3>
- </p>
- <p>
- You can handle a number of different root fs by defining <code>ver</code>.
