Embedded RTOS Design: Insights and Implementation 1st Edition

I discovered that the book I purchased was primarily written to promote Nucleus rather than provide instruction on designing and implementing a simple RTOS. As it turns out, most of the book had already been published as a series of articles on an embedded software portal. Unfortunately, the code in the Kindle edition is difficult to follow, and no application is included. Additionally, for the preemptive scheduler, the target architecture is the deprecated ColdFire. The author states that buying is better than building. I regret so much buying this book.
