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
I'll take a deeper look at it. Thanks a lot.
