Pros and Cons of using GNU Tools • The GNU development tools are open source • GNU tools are the most powerful and flexible development tools which allow to deliver virtually any kind of embedded solution • GNU tool flexibility extends beyond the target domain • GNU tools are well supported • • • Base distribution does not contain a graphical IDE Documentation is good but widely spread New users can’t get started quickly
