As a learning exercise I want to load on to a spare ATMega328p the version 12a hex code using AVRDudess.? I've found some info on here including the version 12a hex code but not the version 12a eep file refered to in AVRDudess only the older versions.? Any pointers as it been years since I've programmed an AVR and it all changed.

There is no EEP for later firmware. You just load the .hex. And if it is a new or non QRP Labs chip set the fuses.

Many thanks

Alan, how do youset the fuses?? It's all new to me also. Carl

For the values read here /g/QRPLabs/message/24845

I'm not a regular Avrdudess user so best if someone else guides you.

Did my first one this afternoon using an Arduino to program it on the board.? The information for the settings including the fuses are here?/g/QRPLabs/files/AVR%20Programming and reading the aVRDundess1.pdf file.

The programmer I used was this one?http://prajankya.blogspot.com/2015/11/programming-standalone-avr-with-arduino.html but I used the onboard ISP rather than the breadboard and oscillator shown here.

Len,

I don't know why but the fuse settings do not seem to agree with Hans /g/QRPLabs/message/24845

They say bride comes before the fall.? I blew my AVR by failing to remove the link between the PA and +5V and applying 12V. Unfortunately the replacement got stuck in the Turkish mail system for ages so I thought I program my own.

Everything looked fine but it didn’t see the Si5351. Long story short, the proper AVR turned up and it works perfectly with Han’s version of 3.12a of the AVT but not the one I programmed. I programmed it using an Arduino ISP sketch, AVRDudess with the recommended setting L 0xF7 H 0xDC E 0x07.? Everything in the menues looks fine but the clock runs really slow. Any thoughts?
