This buildroot is for xbmc development for the Raspberry PI.

The buildroot is based on upstream buildroot git : bce34ab199dea7e8430971ae31d743e246049785

Requirements for ubuntu :

apt-get install build-essential libssl-dev git libncurses-dev bison flex texinfo zlib1g-dev gettext autoconf patch

Getting buildroot :

mkdir /opt/xbmc-bcm cd /opt/xbmc-bcm export BUILDROOT=/opt/xbmc-bcm/buildroot git clone https://github.com/huceke/buildroot-rbp.git buildroot

Building buildroot :

cd $BUILDROOT

make rbp_defconfig make

Output of buildroot is located at :

$BUILDROOT/output/images/

There you find the necessary binary files and the rootfs for the PI.

Prepare the nfs exports :

mkdir -p /opt/bcm-rootfs mkdir -p /opt/xbmc-bcm/xbmc-bin cd /opt/bcm-rootfs tar -xpf $BUILDROOT/output/images/rootfs.tar

Edit etc/fstab and add the nfs mounts :

Edit /etc/exports and add

/opt/bcm-rootfs 192.168.1.0/24(rw,no_root_squash,no_subtree_check,async) /opt/xbmc-bcm/xbmc-bin 192.168.1.0/24(rw,no_root_squash,no_subtree_check,async)

Reread exports :

exportfs -r

Partition a sd card with the following partitions :

1 -> FAT 2 -> Linux root 3 -> Linux swap

Copy $BUILDROOT/output/images/{bootcode.bin,cmdline.txt.example,loader.bin,start.elf} onto the FAT partition. Rename cmdline.txt.example to cmdline.txt.

Edit cmdline.txt and change the settings to your needs.

otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 nfsroot=192.168.1.2:/opt/bcm-rootfs ip=192.168.1.3:192.168.1.2:192.168.1.1:255.255.255.0 rootwait smsc95xx.macaddr=08:00:24:00:60:03 quiet

Here 192.168.1.2 is the nfs server ip address. 192.168.1.3 is the ip address of the PI. 192.168.1.1 is the DNS server.

Getting xbmc :

cd /opt/xbmc-bcm git clone https://github.com/xbmc/xbmc-rbp.git

cd /opt/xbmc-bcm/xbmc

vi tools/rbp/setup-sdk.sh

Change the buildroot location after "USE_BUILDROOT==1" case to :

BUILDROOT=/opt/xbmc-bcm/buildroot

Run tools/rbp/setup-sdk.sh

sh tools/rbp/setup-sdk.sh

make -C tools/rbp/depends/xbmc make make install

Xbmc binaries and depends are install in /opt/xbmc-bcm/xbmc-bin.

Buildroot hints :

User : root Password : xbmc

If libnfs fails to build :

rm -rf rm -rf output/build/libnfs-345422a2e32b22119054224003655468771b15fc make libnfs make
