Hello! Here is a general question that probably doesn't have a definite answer: What data does memory (static RAM) hold if it never was initialized? What I mean is if the controller boards (with external S-RAM) are manufactured, then a software is loaded that doesn't access parts of the RAM, is it possible to "know" what data one would find there before writing to it? A couple of tests with different boards gave me always $FF for every memory location never initalized, but I am not sure if one could count on this. Might also depend on the manufacturer of the RAM... maybe? Thanks for any help Holger
Hi Holger: I cannot really answer your question but the rule of thumb I usually follow is to never count on things that are not absolutely guaranteed in the data sheet of the device I'm using. -Walt
