Summary: Very beginners guide simple things to write about
Review: Sorry,
This is not embedded systems. There is far too little useful
information related to embedded linux and more on higher level
issues. I cannot give this book to a software engineer and
have him(her) make a transition from hosted to embedded even
in Linux -

Summary: good introduction to linux embedded systems
Review: The overall impression is good. Focusing an embedded project following a potential practical case is a good idea. Its also a good idea to bring three diferent platforms as a case study, making it clear that linux gives enough abstraction level. I didn't rate it 5 because it relays on hardhat (tm) already built development tools, which is far from being the standrad way to build those tools. Is not that dificult to explain how to make them from source.

Summary: Excellent pratical examples.
Review: This is the best Embedded Linux book I have read so far. The Author has an excellent approach on the subject. He takes a real life application and proposes real solutions. Another strong point about this book is that the Author use of 4 different uP platforms as example (i.e. PowerPC, StrongARM, x86, COTS x86). This provides the reader with a wide view of the extraordinary possibilities of embedded Linux. The Chapter on setting-up a reference development platform is very useful. This is maybe obvious for many engineer out there but unfortunately I have seen to many time that is not a universal approach. Maybe some of the scripts listing should have been left to an include floppy disk.

Summary: Mostly about interfacing
Review: With over 200 of the 400 pages dedicated to interfacing, it seems the emphasis of the title should have reflected this. A more appropriate title would be "Interfacing in an example embedded Linux application". There are many pages of entire listings which could have been made available for download instead. Although the hardware diagrams are appreciated, they are not specific to Linux. Overall, you may find the examples useful, but you will need to dig deeper to understand the real issues.
