[LEDE-DEV] Open WRT Raspberry Squashfs build

[Michael Wulz]

Hello guys,
i'm new to this mailing list and got a recommendation from a OpenWRT
developer to it.

My problem is, i want to automatically build an squashfs image for
raspberry PI and OpenWRT.
All of this work done by hand works successfully, but i'm not so
familiar with the Makefiles
specially the "image/Makefile" which looks really different in all
hardware/cpu models.

I got some information about it on
https://wiki.openwrt.org/doc/techref/image.makefile but this is not
applicable to for example
https://dev.openwrt.org/browser/trunk/target/linux/brcm2708/image/Makefile
this file.

Is there somebody how implemented it successfully?

Here is information about how i did it by hand:
- my /root dir of OpenWRT is in
$OWRT_HOME/staging_dir/target-arm_arm1176jzf-s+vfp_musl-1.1.15_eabi/root-brcm2708/
- make image: "# mksquashfs
$OWRT_HOME/staging_dir/target-arm_arm1176jzf-s+vfp_musl-1.1.15_eabi/root-brcm2708
rpi_squash.img -all-root -noappend -no-exports"
- copied Kernel from
$OWRT_HOME/build_dir/target-arm_arm1176jzf-s+vfp_musl-1.1.15_eabi/linux-brcm2708_brcm2708/
and renamed it to kernel.img
- this images (kernel and squashfs) copied to a FAT32 formatted SD Card,
changed the config files for RPI to boot from squashfs and specified
kernel and GO.

this process would be nice to automate via Makefiles if i choose
"squashfs" in .config File of the owrt-builder
(CONFIG_TARGET_ROOTFS_SQUASHFS=y)

regards
Michael
