emBIOS on the 4G Nano

This is the wiki for the freemyipod project. Freemyipod is a project for reverse-engineering iPods with clickwheel and creating tools and documentation so that other people can port alternative firmwares to them such as rockbox.

Updates

• 2010/08/13 - emBIOS is continually being improved and the next step is porting tools like iLoader to use it.
• 2010/08/06 - The wiki has now been moved to www.freemyipod.org
• 2010/08/05 - Recently we've been working on a hardware abstraction project called emBIOS. Follow development here
• 2010/08/03 - We can now access the Nano 4G accelerometer.
• 2010/08/02 - serpilliere managed to decrypt the NOR flash on the iPod nano (3rd generation).
• 2010/08/01 - serpilliere managed to access and dump the NOR flash on the iPod nano (3rd generation). This code could possibly work on the Classics.
• 2010/07/27 - The server got zapped by lightning but a new one was up and running within a day.
• 2010/02/23 - We can now execute code on everything besides the iPod nano (5th generation)! Minimalistic iBugger working on iPod nano (3rd generation)!
• 2009/11/01 - iBugger core v0.1 successfully running on iPod nano (4th generation)! [1]
