이번 강좌에서 buildroot 환경 설정하는 방법을 설명하도록 하겠습니다.

buildroot 는 저번 강좌에서 소개한 사이트에서 파일을 직접 다운로드하거나 아래의 방법으로 다운로드하면 됩니다.

파일 다운로드

   tmp# git clone git://git.buildroot.net/buildroot

   tmp# ls
   buildroot

   tmp# cd buildroot
   buildroot# ls
   CHANGES  Config.in         Makefile         README  board  configs  fs     package  system
   COPYING  Config.in.legacy  Makefile.legacy  arch    boot   docs     linux  support  toolchain


환경 파일들
   buildroot 에서 환경 설정은 다음 디렉토리에서 확인 할 수 있습니다.
   즉, 이 디렉토리에 있는 환경 설정들이 적용한 프로세서들입니다.
   이 환경 설정을 기본으로 원하는 프로세서에 적용하시면 됩니다.

환경 설정하기

  EM-IMX6DQ보드는 freescale의 i.mx6q 프로세서이므로, freescale_imx6qsabreauto_defconfig, freescale_imx6qsabresd_defconfig 중 하나를 복사해서 사용하거나 둘 중하나를 그냥 사용하시면 됩니다.

  buildroot# cp configs/freescale_imx6qsabresd_defconfig configs/falinux_em-imx6dq_defconfig

  [환경 적용하기]
  buildroot# make falinux_em-imx6dq_defconfig
  mkdir -p /staff/tmp/buildroot/output/build/buildroot-config/lxdialog

다음 강좌에서는 make menuconfig를 설정하는 방법을 소개하도록 하겠습니다.
