I´m a newbye in AVR programming. I built an Usb programmer using Thomas Fischl website´s info, and because I start with an atmega8 chip with no bootloader, I need to program the chip. I don´t have another programmer so I decided to use my arduino diecimila as ISP programmer. Ok. Searching the web I discovered Avrdude. Using Avrdude and arduino I can now flash a file into the atmega, and read the fuses and the lock byte, I´ve done it with good results (or at least is what AVRdude says) but everytime I try to WRITE on the fuses or write on the lock byte AVRdude fails and skips this task. I´m searching the web and learning about AVR, but by now I have no found the the reason for this behaviour. The system seems to be working all right in all the other tasks.
Thanks in advance.
