Our layout girls are probably busy making "Joerg" voodoo dolls right now ;-) I'd say that we should consider GTA04v1 (v0 ? ;-) as a first test balloon, where we can do things that won't make sense in the final product, if doing those things helps us to speed up development. This will also help us avoid endless haggling about some minor features that may get overridden later by larger design decisions anyway. So I'd agree with the MPU being able to do more than strictly needed. Then, as development continues, we'll gradually get a better idea of what we really need and what not, and then we can always decide to remove some connections or even to pick a less powerful and cheaper chip. By the way, "help to speed up development" should also go for our hardware team. If any of this sounds unreasonable for you, please don't hesitate to raise your concerns. It wouldn't do us any good to design a software engineer's wet dream platform where all the system software can be easily done in half a day, but where we need a 50-layer board and dozens of prototype runs to get the hardware working ;-) > BTW: which number of LED is GTA04 I don't think we know yet. I think Steve hates them a bit. I'd like to have at least one "engineering LED" for debugging, but it doesn't have to be visible when the case is closed :-) - Werner
