Since there is not gdb debugging support (I am assuming) I am resorting to printf() development and debugging. If there is a better way then I am all ears. Other than that, I just want to be able to see something work before proceeding. The "wedge" is intended to be a program that is started by Redboot, does its thing, then in turn will start up the Linux kernel, such as with a layer in a protocol stack.
