Most likely problem isn't in BDI but in your setup. Depending on 
the particular chip model, to be able use workspace you must have 
initialized memory first. In fact, I'm pretty sure you haven't 
configured chip correctly to make workspace usable. I've been using 
BDI with various PowerPC and MIPS SoCs for many years. It's an excellent 
tool, you just have to use it correctly.
