Hey there everybody! I'm trying to burn an ATmega8535L-8AU AVR for a flash programmer (http://nesdev.parodius.com/bbs/viewtopic.php?p=94542&highlight=&sid=c2ee59e5ffc57425a3007b5102b54c68#94542) but i'm not getting anywhere with it. I tried 3 of 4 different interfaces: the AVR ISP with STK200/300 pinout, the si prog base board, the avr pg1b. All were functinal except the SI Prog. I don't know what was the deal with it. The program was failing to detect it despite the fact that I checked every connection multiple times. So, as I was saying, the interfaces were functional (Test OK), and I managed to program an 8515 already, but no sign of working with the 8535. The Device Missing (-24) error keeps on being displayed. Can anyone spare some advices regarding my problem? I worked on it for a week and I can't figure it out. Thank you!

Thanks for the support, assholes!
