No, this is the standard flash, and this is simply a part of the vector table (JMP 0x27A). ;-) You probably need to read the production signature row. > But I don't know what that means. The markings are "ATXMEGA256A3U AU > 1235". That doesn't mean anything, except it's an ATxmega256A3U, produced in 2012, week 35. There must be another number on it that ends in a letter. This letter would be the revision. > I don't know if the AVR Dragon page includes A3U when they say A3. A3 and A3U are different, but I seem to remember even the A3U has limitations for the Dragon. Of course, an A3 revision A is something else than an A3U revision A. Revision numbering (lettering ;) starts anew for each device. -- cheers, Joerg .-.-. --... ...-- -.. .
