Hi Helen, I strongly advise you to* avoid *use of Atmel Studio or the Microchip successor.
Using the standalone Atmel assembler in Windows is a much easier solution to control. The Microsoft VisualStudio software bogs down and has a very challenging learning curve with getting good results. *It sounds as though you successfully compiled binaries in hex files, but you may very likely hit a snag in AVRDUDE. * It is very common when installing Forth to deploy the wrong fuse setting and end up with no serial port response. So you might consider using an online Atmel Fuse calculator to confirm your fuse settings. HERE IS A LINK ==> https://www.engbedded.com/fusecalc/ THERE ARE OTHERS IF THIS ONE DOESN'T APPEAL TO YOU. +++++++++++++++++++++++++ Also, make sure that you understand what the AVRDUDE output is saying. There are 3 separate parts to a successful download. The .hex file for the flash, the .hex file for the eeprom, and the FUSE settings. If you don't your ATmega2560 binaries are correctly compiled, AmForth does have precompiled ready to load ATmega328p binaries that you can load to an ArduinoUNO as a way of learning to understand AVRDUDE and proper FUSE settings. I hope this will help. George Herzog On Wed, Sep 8, 2021 at 3:33 AM Helge Kruse <helge.kr...@gmx.net> wrote: > I am a newby to amForth. I want to use it at ATmega 2560.
