This the Buildroot support for the LPC3131 based Gnublin board (see here: http://en.gnublin.org/) and to the Elektor Linux board (http://www.elektor.com/news/elektor-presents-embedded-linux-made-easy.2147294. lynkx) Unfortunately currently the AD and the pwm modules are not supported, i'm about to add also those drivers as well to the current kernel later. Base kernel version: 3.7 (available here: https://gitorious.org/linux-3-7-gnublin/linux-3-7-gnublin/commits/gnublin- support) U-boot version: 2009.11 (available here: https://gitorious.org/u-boot-gnublin-support/u-boot-gnublin-support) Steps to create a bootable SD card (with the given config you need an at least 500 MB SD card): 1.Config buildroot with the gnublin_defconfig: $ make gnublin_defconfig 2.Tweak the config for your needs: $ make menuconfig 3.Build: $ make 4.Create two partitions on your SD card, one with type of BootIt (fdisk ID: df), the size should be around 1M, and another partition with all of the left space on the card, and with the type of normal DOS partition. 5.From the output/images directory dump the u-boot image to the BootIt partition (probably you have to modify the output /dev files according to your system): $ dd if=output/images/u-boot.bin of=/dev/sdc1 6.Dump the root fs image as well: $ dd if=output/images/rootfs.ext2 of=/dev/sdc2 7.Insert the SD card into the board's slot, and your board should boot up with your newly created system.
