Due to AT91SAM9261 chip errata booting from NAND flash is not supported. U-BOOT The used U-Boot is a GIT pull from June 11 2009, along with minor modifications to add support for SAM9-L9261. In order to compile from sources: Extract the sources: tar xjf u-boot-git20090611-olimex.tar.bz2... - Page 6 . The other option is to use a ready-made binary 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.

distinctive heartbeat pattern. LEDs can be manually controlled from the Linux shell prompt. For example, to switch on LED2: echo 255 > /sys/class/leds/led2/brightness And to switch it off: echo 0 > /sys/class/leds/led2/brightness EXTENSION PORT The board has an extension port EXT with eleven GPIO pins that can be controlled from user-space Linux applications. - Page 9 setup the pin correspondingly as an output with initial high value, output with initial low value, output or input. Example: echo high > /sys/class/gpio/gpio39/direction echo in > /sys/class/gpio/gpio40/direction Outputs can be controlled by writing to the value file like this: echo 0 >...

This will cause trouble if there are two or more boards in the same local network. Assigning a custom MAC address is easy. When U-Boot is starting press a key to enter the U-Boot shell. There set the Ethernet...
