Source Code

The AudioPlus Linux source code is currently available in two different development source trees managed with Git.

The main AudioPlus development git repository is hosted here. This repository is based upon the kernel.org Linux tree. Notifications of changes to this repository are mailed to the audioplus-commits mailing list. This repository contains drivers for the WM8350 and WM8400 PMICs.

The other AudioPlus git repository is based on the IMX31ADS Linux BSP from Freescale. This repository will eventually be merged into the main AudioPlus repository above. The IMX31ADS repository is here . This repository has two WM8350 branches for IMX31ADS - wm8350 and wm8350-stable.

Git is also available on Windows running under Cygwin.
