The Rockbox Sansa e200 port
Rockbox doesn't function on the v2 models. The v1 firmware is named 01.xx.xx, while the v2 firmware begins with 03. This version number can be retrieved under Settings->Info.
Install
Full installation and uninstallation instructions are in the Installation Chapter of the Rockbox Manual. Owners of Rhapsody/e200R 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 (|<< ) or connect the USB cable while the player is off.
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.Hardware Details

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.
Rockbox Status
At present:- LCD driver
- This needs to be changed to do synchronous updates to stop flickering
- Backlight
- Flash driver - This can be substantially improved by using DMA and sleeping/yielding appropriately
- MicroSD card driver - Functional as of 30 June 2007.
- MicroSDHC card driver - Functional as of 22 August 2007. Feel free to test various capacities and tell us your results!
- Button driver - GPIO IRQ button driver enabled in SVN as of 06-03-2007.
- USB handler
- The Sansa recognises when the USB has been plugged in, but does nothing more.
- Power handling - Not yet optimal
- Audio DAC driver - Recording now works as of 5 June 2007, but only through the built-in microphone.
- FM Radio - Functional as of 06-06-2007. The driver still needs tweaking, but it's working.
- Clock (RTC)
- Not all plugins have been adapted to the Sansa's screen layout yet.
- The keys used in some plugins are not optimal. Discussion on better keys is appreciated (see, for example FS#6467.)
Rhapsody/e200R Models
More information here. If the USB options on your player are "MSC" and "MTP" it's non-R, if they're "Rhapsody" and "Plays for Sure" then it's R.FAQ
