    Cirrus Logic Audio Card working on the Raspberry Pi 2

    ragnar.jensen

      Hi all!

       

      As you might know, Cirrus Logic's main kernel source branch recently switched to 3.18.

      My first thought was "Hmm, that means the Cirrus Logic card could finally work on the RPi2..."

      I have built a couple of 3.18 kernels for my B+ and RPi2 and I have managed to get both models to produce sound

       

      It's still early days, i.e. there are possibly bugs and glitches to fix, but for those of you who would like to try it out I've made an image file that you can download here:

      https://drive.google.com/file/d/0BzIaxMH3N5O1cmJ1bFhMcG1hc0E/view?usp=sharing

      The file is a 1.3 GB zip. Uncompressed size is 3.1 GB, so it fits comfortably on a 4 GB card.


      The image is based on the standard 2015-02-16-raspbian-wheezy image from the Foundation that you flash to a SD card for a fresh install.

      I have only added my kernels and set up the configuration files to get the card going.

      It should work on the older B model  with a Wolfson Audio Card too, but I haven't tested that yet.

       

      Have fun!
