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
