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 is modified to be used with the MP201.
The boot loader is U-boot v1.1.1, which is also modified with code for the MP201.
