No I didn't mean I have no reset circuit at all. I have a standard R-C reset circuit. 10µF-10K combination. As the very first thing, before you start experimenting with different bootloaders, get rid of the RC reset and get a real reset IC. (TL)7705 will do; then instead of the '125, DTR can be connected to the pushbutton input. JW PS. http://www.8052.com/faqs.phtml?FAQ=119931 http://www.efton.sk/misc/reset.pdf |
