Some scripts for tweaking freebsd-wifi-build for the Carambola2. This project initially started because I wanted to build as a normal user instead of root, however has evolved into a more general automation script for my purpose, as user build is becoming the default mode for freebsd-wifi-build.
- Tested build host using FreeBSD release/10.0.0 inside a Linux debian wheezy amd64 hosted qemu-kvm machine.
- Tested for destination FreeBSD release/10.1.0
- I also had it working with destination release/10.0.0 but that was early on so I dont know if it will still work.
-
Setup stuff
$SUDO pkg install gmake bison dialog4ports git wget subversion fakeroot lzma uboot-mkimage libtool
-
Create a working directory.
mkdir whatever && cd whatever
-
Clone this repository
git clone carambola2-freebsd-userbuild
-
Clone freebsd-wifi-build
To get simplify working with tftp, I cheated and did chmod 777 /tftpboot, which also required:

This may become unnecessary in due course once freebsd/freebsd-wifi-build#4 is resolved.
-
Clone freebsd, or just get the release sources. One way to do this is
wget https://github.com/freebsd/freebsd/archive/release/10.1.0.zip unzip 10.1.0.zip
-
Generate a ports working area
mkdir portsnap ports ports-distfiles portsnap -d portsnap fetch portsnap -d portsnap -p ports extract
-
Hack configurations, for example
freebsd-release-10.1.0/sys/mips/conf/CARAMBOLA2to enable MSDOSFS
Instead of modifying freebsd-wifi-build I hacked my own changes into the firmware directory tree inside build_carambola.sh
You can also edit the script to add extra ports.
I did also modify freebsd-wifi-scripts to remove more stuff from the world build:
+echo 'WITHOUT_GAMES="YES"' >> ${X_DESTDIR}/../src.conf.${BUILDNAME}
+echo 'WITHOUT_DOCS="YES"' >> ${X_DESTDIR}/../src.conf.${BUILDNAME}

Run
scripts/build_carambola.shcarambola2-freebsd-userbuild/build_carambola.sh
This generates a single flashable file in the end to make life easier inside u-boot.
Which means you can do the following once:
setenv ipaddr 192.168.0.244
setenv serverip 192.168.0.107
saveenv
Then you can simply hit the reset button on the carambola to test a new firmware image:
erase 0x9f050000 +0xd90000
tftpboot 0x80050000 kernel.CARAMBOLA2.lzma.flash
cp.b 0x80050000 0x9f050000 $filesize
reset
SOURCES=freebsd-release-10.0.0 carambola2-freebsd-userbuild/build_carambola.sh
FreeBSD kernel ignores the uboot environment. I worked out how to fix this:

The 'stock' Carambola2 OpenWRT build from 8devices (and the trunk OpenWRT) configures the ethernet ports backwards from FreeBSD at least through to 10.1.0, and independently routes them, whereas FreeBSD defaults to switched, which is not much use as a firewall.
The FreeBSD kernel in -LATEST actually allows the network ports to be swapped. I was unable to succesfully buildworld against -LATEST using freebsd-wifi-build but I was however able to use the release-10.1.0 userland with the -LATEST kernel, the script allows for this by setting ${SOURCES_KERNEL} !
Once that it done you can modify CARAMBOLA2 and CARAMBOLA2 hints:
