They may be different under the hood and have subtly different meanings, but both work in Linux GCC and AVR-GCC without the __flash qualifier. I've seen these statements used interchangeably in Linux C code, for instance.
The relevant question is, what is the behavior of __flash that causes one to work when the other doesn't when compiling for AVR? ~James On Sun, Jul 6, 2014 at 12:25 PM, Jim Wagner <wagneja...@comcast.net> wrote: > Big Difference.
