Problems Programming

Post by boydflizzle »

I'm unable to get my ATmega48 programmed. I have tried to program it on the GOL board in ISP mode and AVR studio, AVR dude and winAVR none have recognized it. I have tried it with 4 different ones. But, I did purchase one preprogrammed from the adafruit store and they all recognize the preprogrammed one, but don't recognize any of the ones I have bought directly from digikey.

Do I need to burn the fuses to a certain setting before I program it? I'm using the Atmel dragon programmer.
Anything anyone can suggest would be great.

Seems to me I read something about the clock frequency. You might try a search in the TinyUSB programmer forum.

Still, I think I saw something about the clock being set to internal or external and having trouble programming that might be of help. I guess you will have to search the whole site.

A suggestion about fuses i ones heard was:
Don't trust the factory settings!
Since that i always set the fuses before i use/program an atmel for the first time..
