Rockbox port to Archos AV320/340/380 devices

Current Status

A stub of a port was left in the codebase up until revision a820a98361, when it was finally removed. Consider this a stillbirth port. This page remains only as a matter of historical interest.

ArchOpen

The AV3xx series is well supported by the ArchOpen project. This will provide a lot of source code for a Rockbox port, as well as the aoEmulator which is a hardware emulator of the AV3xx (amongst other devices).
