Sony NW-A808 Port

Sony NW-A808 Port

This is a pre-development, no code is actually written and it is not certain if it is even possible to port the player to Rockbox.

Player Overview

Info about the player can be found here:

The player is running a modded Linux kernel (2.6.10) on a NEC MP201 Processor, which has an ARM processor in it.

Service manual:

As seen in the service manual, there are wiring diagrams and description of all components. It also reveals that NWZ and NW series uses the same hardware.

Software overview

The player is running a modified linux kernel (2.6.10) running on a FAT filesystem. Sony has released the development tools they have used and a kernel, which seems to be modified.
