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 -->

buildroot/target/device/armadeus/apf27/uClibc-0.9.30.config.arm

• idem for U-Boot config:

buildroot/target/device/armadeus/apf27/apf27-u-boot-2010.03.h

Changes since BR version used in armadeus 4.x

• TBDL

How to use recent BR in armadeus

• checkout a recent clean GIT view and before any other command edit the main Makefile to change the BUILDROOT_VERSION flag from 2013.11 to the wanted BR version.
  • comment line 30
  • uncomment the line 29 and modify it
• then you can use it as old BR:

$ make apf27_defconfig
$ make

• you may need to create a new patches directory:

patches/buildroot/201x.xx/

Patches that could be sent to BR

(Some will require some cleanup)

Instructions

• Patches to port: patches/buildroot/2013.11
• when working on a patch mark it with:
  • ** <span style="color:orange">'''In progress'''</span> ~~~~
  • --> In progress JulienB 14:14, 9 November 2010 (UTC)

  • 000-xxxxxxx.patch
• Write OK in bold green and your name (automatic with 4x'~') when corresponding patch has been ported:
  • ** <span style="color:green">'''OK'''</span> ~~~~
  • --> 000-xxxxxxx.patch: OK JulienB 07:06, 21 October 2010 (UTC)
• How to:
  • get a BR git
  • try to apply patch with patch -p1 --dry-run < patch_name.patch
  • when it applies remove --dry-run, commit, generates patch with GIT and send it to BR

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 git://git.busybox.net/buildroot 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.. -s

• this will give:

 0001-Summary_of_your_work.patch

• send patch to BR (check https://buildroot.org/downloads/manual/manual.html#submitting-patches before ;-) ):

 $ 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:
