$ make apf27_defconfig
$ make

How to send patches to BR

(see the Buildroot - How to contribute page)

• 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..my_work -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..my_work -s

• adds version inside [PATCH] ex: [PATCH v2]
• adds comments after ---, ex:
