Hi all I have to add an In-Application Programming feature to my program. I'm using 89c51rc2 with no external memory and keil. I've read several threads about IAP but not found exactly the thing itself. At the moment, I - I have a 'boot' program, which looks if there is a new program on the high part of the flash (previously written there by the application or normal program), by means of an absolute addressable variable. If there is a new program, boot copies the program at the low part of the flash. - After that, it is supposed that boot must jump to the application program. But I guess I'm getting in trouble with interrupt vectors or some other conflict. I'd appreciate an example or a link. Thanks in advance
quoting the NoTouch document: This method may, of course, be used even if the program is not updated through a PC running a program such as FlashMagic, the data stream may be issued by any means as long as it conforms to the record format specifications in the data sheet.
I'll take a deeper look at it. Thanks a lot.
