SanDisk Sansa Clip

Current Status

Rockbox does NOT run on the SansaV2 players.

SanDisk Sansa Clip players are a totally new line of products which indirectly replaces the M200 series, and Rockbox has NOT been adapted to run on this hardware yet. It will take a considerable effort to make it do so.

Sansa v2 firmware file

The SansaV2Firmware? page explains the firmware file details needed for porting of Rockbox to Sansa v2 models.

A growing collection of extracted firmware files can be found at Daniel's Sansa Series v2 Firmwares

Hardware

For a disassembly of the Sansa Clip hardware, see http://www.anythingbutipod.com/archives/2007/11/sandisk-sansa-clip-disassembled.php

Components:

• 3.7V lithium battery
• AMS AS3525 SoC, see: http://daniel.haxx.se/sansa/v2.html
• Sandisk flash chip, appears to comply to ONFI pinout.
• 24.00 MHz crystal
• FM chip (markings 0216 B2Y2? 0735): Silicon Labs Si4702 (identified here)
• display controller: Solomon Systech Ltd. SSD1303
• OLED display: Udelco UG-2864 Blue/Yellow

The Sansa Clip is apparently different from the other V2's because it has no SDRAM chip.

JTAG

On Sansa E200v2's there is an 8-pin JTAG port (see http://forums.rockbox.org/index.php?topic=14064.msg121222#msg121222) with probably the following pin layout:

1: VDD    +
2: TCK    JTAG Clock
3: TDI    JTAG data in
4: TMS    JTAG test mode select
5: nTRST  JTAG test reset, active low
6: TDO    JTAG test data out
7: nSRST  System reset, active low
8: GND    -

The Clip also has 8 pins below the USB connector (on the other side of the PCB), possibly this is JTAG too.
