The Rockbox Sansa e200 port

Identification of version

Look under Settings->Info - if Version has the format 01.xx.xx, the unit is a v1. All other indicators, such as markings on the casing or packaging, are unreliable due to SanDisk's practice of using the same values on different models.

Other versions

v2

Install

Full installation and uninstallation instructions for all supported devices are in the Rockbox manual. Owners of e200R/Rhapsody models go here.

Bootloader

There is a working bootloader that can load and run Rockbox or the original firmware. To go into the original firmware, turn on your Sansa while holding down the left button ( |<< ).

---

Simulator

There are currently simulators for all Rockbox compatible devices. A simulator can be useful for seeing what Rockbox looks and feels like before installing as well as testing out your homemade themes before putting them on your player. The e200 simulator is here.

---

Emulator

There is a working emulator for the e200 posted on Flyspray. It currently boots Rockbox and decodes MP3, as well as the retail bootloader, however it does not yet load the retail firmware because it supports only one CPU core. See here.

i2c ROM

There's a ROM accessible via i2c on the target that we casually call the i2c ROM. It seems to contain the pre-boot loader that loads the BL.rom bootloader from the secret partition off the NAND flash and starts it.

• Read the partition table (block 0) from the NAND
• Check that partition #2 is of the 'OS/2 Hidden' type (0x84)
• Read the first block of partition #2 from the NAND
• Check that it starts with 'PPBL'
• Read the BL from the NAND starting from the second block of partition #2.
