Thanks for the help, but I was hoping for the routine in hex.
I can't think of any reason why you'd need to directly write to flash from a user program...Only an OS should need to do that, in which case you don't need to bother with a hack, since it's your OS.The only reason for which it could be needed is if you need to create an app directly on-calc. But to do that, you'd have to mess w/the certificate too, and that is just a very bad idea.Anybody have a better guess?
I personally do not like when people say things like "why do you need that?" or "why do you want to do that?" when someone asks for a routine or programming help, because it sounds like it implies any use of it would be pointless or that his idea makes no sense or something, while in fact, the programmer may have something special in mind. Why prevent someone from doing something he wants?
