But I want to create a hex file with a real turnkey application that I can flash on another ATmega2560 device. After running all Forth source code to my "development" board I find the flash filled with the code. It should be possible to clone the flash content to another board without sending all the source trough a UART. The other idea I mentioned was to "dump" the added flash memory content and create an assembler source used in the AVR assembler.
Instead of dumping the contents from the target I found another approach. The g4 <https://github.com/mikalus/g4> converter makes assembly source code from Forth code. I could use it to convert my code to assembler code that I could add the the amForth sources. g4 requires that the referred words are defined, so that you have to provide stubs for words that are missing in gforth but known to amForth, e.g. MS. But as long as you can compile in gforth you can create source files for amForth. Including these new files in you amForth skeleton creates a new .hex file capable to be a turnkey application, in a .hex file.
The reason to differentiate between development board and the target device is that the target device is that the target device has only one USART port connected. And this port is used on a RS485 field bus.
And you can flash the new .hex file on the ISP port. Best regards, Helge _______________________________________________ Amforth-devel mailing list for http://amforth.sf.net/ Amforth-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/amforth-devel
