LeapFrog Pollux Platform: Firmware

Summary
Over the years there has been a handful of revisions to the LeapFrog Pollux Platform Firmware. The Didj started on Linux Kernel version 2.6.20, which involved 2 versions over its lifespan the 2008 and 2009 versions. With the release of the Leapster Explorer the Kernel was upgraded to 2.6.31 and has since seen multiple updates, the latest being the LeapPad Explorer release.

The root file system or userspace has also seen some major upgrades, while most of it is not Open Source software, as in the UI or Flash Lite player, the basic programs are. They contain everything you'd expect to find on a Linux OS, echo, ls, vi, etc, etc.

This page contains various links to tutorials and information on the Firmware. While Didj was vastly different, it can be upgraded to run the new Linux version. This is recommended as most of the Linux work is being done with the latest firmware version. You can find links to older version information in the depreciated section. The updated firmware versions usually end up including whats been added, so often times it will be easier to just move to the latest, but they are there if you need them.
