Configuring Buildroot for the AT91SAM9260? running from a dataflashcard.

$ make menuconfig
$ make at91sam9260dfc_defconfig
$ make > at91sam9260dfc.log 2>&1

The first command will create the initial ".config" file

The second command will copy a valid buildroot configuration to the ".config" file.

The third command will build everything.

Making a custom project

If you want to create your own board support package, you start by using one of the basic boards. (Look in "target/device/Atmel/*" for "<*>_defconfig" files)

make at91sam9260dfc_defconfig will configure to use the AT91SAM9260? running from the dataflashcard.

Once the config file is OK, you could type:

$ make configured

This will unpack linux and busybox in the "project_build_dir/" directory and uclibc in the "toolchain/uClibc-" directory. You can by entering this directory and typing the appropriate command reconfigure the package.

I.E: In linux the

$ make ARCH=arm xconfig

Define a PROJECT name in the buildroot configurator by:

$ make menuconfig

By doing

$ make saveconfig

you will save the configuration of busybox, uclibc and linux in the "local/" directory, and this can be retrieved by

$ make BOARD=<PROJECT> getconfig

Deprecated AT91 Buildroot

#!/bin/bash
# All previous patches was applied to vanilla buildroot from May 31st.
# Most, if not all suggestions from other people have been applied, - thanks!
# Also updated the u-boot-1.2.0-atmel.tar.bz2 so you need to delete this
# from your download directory (default /usr/local/install/downloads)
# --------------
# Updated 2007-06-07: FIx mkimage path problem
