Exploring BeagleBone: Tools and Techniques for Building with Embedded Linux

This is what is keeping me busy at the moment… (very, very busy!). I have presently drafted 9 of the 14 chapters. This book on the BeagleBone is due for publication in Dec. 2014. A provisional description is available at: http://www.amazon.com/Exploring-BeagleBone-Techniques-Building-Embedded/dp/1118935128/
There is a website to support this book at: www.exploringbeaglebone.com
