Instalation of prepared packages.

Follow this link for detailed instructions.

Build & installation from sources.

1. Clone this repository.

   git clone http://github.com/RoEdAl/linux-raspberrypi-wsp.git
   

2. Build package:

   cd linux-raspberrypi-wsp
   makepkg -sL  
   

   Compilation takes long time. Consider using distccd or/and ccache. You may also compile this package on a PC using QEMU Chroot.

3. Install kernel package:

   pacman -U linux-raspberrypi-wsp-4.4.17-2-armv6h.pkg.tar.xz
   

   Optionally install kernel headers package (for developers only):

   pacman -U linux-raspberrypi-wsp-headers-4.4.17-2-armv6h.pkg.tar.xz
   

4. Enable and configure Cirrus Logic/Wolfson audio card in /boot/options.txt file:

   # Configures Cirrus Logic/Wolfson audio card
   dtoverlay=rpi-cirrus-wm5102
   

   Optionally enable mmap support:

   # Enables mmap support in the bcm2708-i2s driver
   dtoverlay=i2s-mmap
   

5. Enable onboard audio interface in /boot/options.txt file if you need it (disabled by default):

   dtparam=audio=on
   

6. Reboot:

   sudo reboot
