|
I. Intro |
|
Before starting any work on ELWIX must we prepare environment. |
|
|
|
What this means :: |
|
- We must downloading freebsd sources from CVS/SVN repository and put on separate place from /usr/src. |
|
Set in config/rc.elwix variable BSDSRC="..." with place where you get freebsd sources. |
|
- We gather from ELWIX CVS repository kodicom_mux project. After this we need to patch our freebsd |
|
sources like that "cd <where you put freebsd sources>; patch -p0 < <kodicom_mux/contrib/kodicom.patch>" |
|
- We must checkout from ELWIX CVS repository core libraries "libait*" , "embedtools", "embedaddons" |
|
and GPLv2 "gpl/*" projects |
|
- Optional download of 3th party software for ELWIX firmware. Project name is embedaddon from ELWIX CVS |
|
|
|
II. Build system process |
|
1. Init build structures with clean directory tree |
|
./build_init.sh <filename of project config> |
|
2. Cross compile entire userland software |
|
./build_world.sh |
|
3. Cross compile ELWIX kernel |
|
./build_kernel.sh |
|
4. Cross compile ELWIX tools |
|
./build_tools.sh |
|
5. Cross compile optional 3th party software |
|
./build_3thparty.sh |
|
--------------------------------------------------------------------------------- |
|
6. Now is moment for build BaseFS ELWIX system |
|
./build_base.sh |
|
--------------------------------------------------------------------------------- |
|
7. Moment comes for build big system binary and inject rootfs image into kernel |
|
./build_rootfs.sh |
|
8. Make romfs image and build big fat second stage firmware image |
|
./build_romfs.sh |
|
9. Now is moment for build RootFS ELWIX system |
|
./build_fs.sh |
|
--------------------------------------------------------------------------------- |
|
|
|
Ok, now we did ELWIX version and placed to build/release directory like tar.gz file |
|
|
|
Example of produced tar balls:: |
|
ELWIX_X.X_target_{base|rootfs|rootfsext}_size_arch_date.tar.gz |
|
|
|
III. Build storage image |
|
1. Build ELWIX system into binary fs image file |
|
./install2img <ELWIX_X.X_target_.....tar.gz> [image_size_in_KB] |
|
2. Build ELWIX system into direct device |
|
./install2dev </dev/daX> <ELWIX_X.X_target_.....tar.gz> |
|
3. Build ELWIX system into separate compressed binary images for u-boot embedded devices |
|
./install2uboot <kernel|kernel_rootfs|rootfs|bin|vendor> |
|
|
