Jan, A number of things.
The hex file you have found may not be one for the Arduino Mega2560. If I remember correctly, the distribution has an appl folder for the atmega2561 and the configuration assembler file https://sourceforge.net/p/amforth/code/HEAD/tree/trunk/appl/atmega2561/atmega256.asm suggests that it was built for an ATmega2561 with an 14.745600MHz crystal and uart1 hosting the AmForth interpreter. I adjusted the AmForth make system (on OSX) to build a custom hex file for the Arduino Mega2560 which uses ATmega2560 chip and a 16MHz crystal. I also put the AmForth interpreter on uart0. The AmForth build system is one of its many strengths, though getting it to work on OS X does require a few extra steps. I used these fuse values for my Arduino Mega2560 > avrdude: safemode: Fuses OK (E:FF, H:99, L:CE) Finally, what hex programmer you use may be important with the Mega2560. I used an avrisp2 compatible programmer and had no problems. However, I can confirm that my usbtiny programmer couldn't program my Mega2560 successfully.
