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. -- Eugene
