RESTORING THE INSTALLATION
1.
Extract the contents of the sam9-l9261-samba.zip archive .
directory,
mainstream 2.6.30 distribution to get linux-2.6.30-olimex.tar.bz2.
Compiling and installing the kernel modules require some additional steps.
First you need to ensure that the target root filesystem is accessible from
the
extraction/manipulation procedures! Then enter the Linux source directory
(where you typed "make uImage") and type
modules_install
Note that the path must be to the target root filesystem's root directory, and
NOT the "lib" or "lib/modules" subdirectories!
We welcome any patches and comments for improving the board support
for SAM9-L9261. The starting point for board-specific initialization is the
following file:
Additional AT91SAM9261 chip specific initialization is located at:
The
distribution.org
distribution like Debian or some pre-compiled Angstrom image. The root
filesystem used in SAM9-L9261 is a slightly modified version of the official
Atmel Linux demo binary.
Additional software can easily be installed by the command "ipkg", provided
that the board is connected to Internet via Ethernet cable. Run
from the SAM9-L9261 shell prompt to see the available options.
Additionally, the sources/debian-lenny-rootfs subdirectory contains a flash
image for Debian Lenny based root filesystem. It does not feature a
graphical demo but user can install additional packages via the standard
Debian utilities apt-get and aptitude.
In order to use the newly compiled bootloader and/or kernel do the
following:

2. Overwrite the binary files with the newly compiled ones.
3. Run the installation restoration procedure below.
