What I always recommend to such an embedded systems programmer is this: Look at Embedded Linux as two parts, the embedded part and the Linux part. Let's consider the Linux part first. The Linux side. Operating systems abound and the choices are many for an embedded system, both proprietary and open source. Linux is one of these choices. No matter what you use for your development host, whether Linux or Windows or Mac, you need to learn how to program using the target OS. In this respect, using Embedded Linux is not greatly different from using VXworks, WindowCE, or another OS.
