the target of your code is probably the zero page of RAM, where the
downloader bootstrap routine lives.
so as your code is being downloaded, you're over-writing the
hc11-ram-based dl comms code and the host side ultimately fails.

| Hy! I have problems downloading a self compiled file to my Handyboard (with 68HC11A1). I just wrote a little test programm: int main() { int foo = 0; while (foo < 1000) { foo++; } return(0); } and compiled it to a .s19 file with the gnu gcc 68hc11 (...)
