Atmel SAMA5D3 Xplained board ============================ This document explains how to set up a basic Buildroot system on the Atmel SAMA5D3 Xplained board, whose main site is http://www.atmel.com/tools/ATSAMA5D3-XPLD.aspx. Additional details can also be found on the http://www.at91.com/linux4sam/bin/view/Linux4SAM/ web site.

Some adjustments in the bootloader configuration will be needed to boot from NAND flash, see board/atmel/nandflash.txt Configuring and building Buildroot ---------------------------------- make atmel_sama5d3_xplained_mmc_defconfig make Preparing the SD card --------------------- The SD card must be partitioned with at least two partitions: one FAT16 partition for the bootloaders, kernel image and Device Tree blob, and one ext4 partition for the root filesystem. To partition the SD card: sudo sfdisk -uM /dev/mmcblk0 <
