Just flash 1802.hex file above arduino file.

Thought it was good that both arduinoFile.hex and 1802asm.hex could be flashed together. But it's easier than that. Just flash 1802asm.hex file into existing arduino nano flash containing normal blink.hex or other. Like this:


c:\tinyc\avrdude -CC:\tinyc\avrdude.conf -v -patmega328p -carduino -PCOM15 -b57600  -Uflash:w:hi.hex:i -Uflash:r:dump0.bin:r

The file dump0.bin not really needed but it was good to check whole 32K read back.

Still not tried on mega with big 13k cdp1802e93.hex program. Next task.

Didn't work on mega. This did on nano.:

Going to try:
c:\tinyc\avrdude -CC:\tinyc\avrdude.conf -v -patmega328p -carduino -PCOM15 -b57600  -Uflash:w:high2.hex:i -Uflash:r:dump6.bin:r
This seems to work. But it doesn't on mega. Not sure why.Changed high2.asm around and it still works. around $5000. NB old stuff around $4000 still there too.
