---+!! Rockbox port to the AV120/140 Devices

%TOC%

---+ Current Status

Current this port is only in the planning stages. This page currently only for documenting the hardware. No code has been written yet.
When work has been done, this page will be updated to reflect what has been done. In the meantime, keep watch on both this page
and the forum thread: http://forums.rockbox.org/index.php?topic=1389.0

---+ Hardware Summary

The AV1xx models are a rather interesting line of Archos players. Roughly resembling the Jukebox Recorder v2 players externally, the hardware
under the hood is completely different. One of their big draws was their ability to play !DivX, !XviD, and AVI video files.
The main components of the system are as follows:

   * Texas Instruments !TMS320DSC25 (54 MHz !ARM7TDMI plus DSP, 32KB IRAM, no cache)
   * Micronas !MAS3587F audio codec/DSP
   * ATMEL !ATF1504ASV !15AC100 0238 Programmable Logic Device
   * 16MB of RAM supplied by 2 !IS42S16400A ISSI (64 Mbit - 8 MB) RAM chips
   * Cypress !CY7C58300 56LFC USB Bridge (USB 2.0/ATA/ATAPI)
   * STMicroelectronics !M41ST84W 512-bit (64 x 8) serial RTC with supervisory functions
   * Epson !L2E1811D LCD Controller
   * Epson !L2B18009-B000 LCD (237x234x16)

Like most other early Archos devices, these players use a 2.5" hard drive for storage, and are user replaceable. Information on the hard
drive used in these models would be appreciated.

---+ !ArchOpen

The !AV1XX series is very well supported by the ArchOpen project. This can provide a lot of source code to get a Rockbox port started. The aoEmulator (available at the project site), although a hardware emulator for the !AV3XX devices, should be able to emulate the !AV1XX as well.
