An embedded Linux training and consulting firm in the South of France has published some 360 pages of free training presentations on embedded Linux topics. The Free Electrons presentations cover topics including Linux changes since 2.6.10, power management, device driver development, and porting Linux to ARM platforms, says the company.
Free Electrons has always released its training materials under a Creative Commons documentation license. The company also routinely posts extensive video transcripts from conferences such as CELF's Embedded Linux Conference.
