Hi there I was also having problems using the loader420.exe to load hex files to a DS89C420 and found your email on the internet. Were you able to resolve the problem? If so, please let me know what you did. Thank you Ian McLeod Ontario, Canada.
Komisch; kriegen die Leute nicht mit, dass das hier ein deutschsprachiges Forum ist? :-? Sowas wundert mich einfach....
man könnte ein englisch-sprachiges Unterforum auf machen...
Hi, I use the DS89C420/ 440/ 450, too. You have to erase the Microcontoller fist!! If you don't do this, the micro can be distroid. Cause the HEX-code can be writen in wrong adresses. In the first time I had this problems too. Regards Benjamin
