Changes since BR version used in armadeus 3.x

default packages

  • uClibc: 0.9.29 -> 0.9.30
  • gcc: 4.2.1-> 4.4.5
  • busybox: 1.6.2

build directories

  • build_arm_xxx/ project_build_xxx/ toolchain_build_arm_xxx/ have been removed and replaced by output/:

configs

  • buildroot default configs are now stored in buildroot/configs/apfxx_defconfig and no more in buildroot/target/device/armadeus/apfxx/apfxx_defconfig
  • uClibc config should be named with version number to not overwrite the old one -->

  • idem for U-Boot config:
buildroot/target/device/armadeus/apf27/apf27-u-boot-2010.03.h

  • checkout a recent clean GIT view (new BR is used since armadeus-4.0)
  • then you can use it as old BR:
$ make apf27_defconfig
$ make
  • new patches dirrectory:
patches/buildroot/2010.11/

How to send patches to BR

  • GIT should be installed and configured on your PC like stated here
  • clone buildroot GIT:
 $ git clone xxxxx buildroot_git_dev/ (TBDL)
 $ cd buildroot_git_dev/
  • take patch from armadeus:
 $ cp /path_to_armadeus_bsp/patches/buildroot/2011.05/0xx-name.patch .
  • create a branch to work (here my_work):
 $ git branch my_work
 $ git checkout my_work
 Switched to branch 'my_work'
 $ git branch
   master
 * my_work
  • try patch:
 $ patch -p1 --dry-run < 0xx-name.patch
  • if it works, apply it for real:
 $ patch -p1 < 0xx-name.patch
  • list changes:
 $ git status
  • do some more changes if needed and then save them:
 ... do changes ...
 $ git add files_changed
 ... test changes ...
 $ git commit -m "Summary of your work"
  • generate patch to send to BR:
 $ git format-patch -M master..libmodbus -s
  • this will give:
 0001-Summary_of_your_work.patch
  • send patch to BR:
 $ git send-email --from=xxx.xxx@xxx.xx --to=buildroot@busybox.net --smtp-server=smtp.xxx.xx 0001-Summary_of_your_work.patch
  • depending on the feedbacks from BR, modify your patch:
 ... do changes ...
 $ git diff
 $ git add files_changed
 $ git commit --amend
 $ git format-patch -M master..mywork -s
  • adds version inside [PATCH] ex: [PATCH v2]
  • adds comments after ---, ex:
