I have app. board with C166 and 128k RAM only connected to C166 by 8b demux bus. I try to configure monitor in Bootstarp mode. When monitor code starts from 0h then there is no problem. Trying to place monitor code somewhere else,let say 01A800h, causes a breaking of "debug session". Tracking a traffic on ASC0 I descovered that at the end of monitor's downloading process (a number of WRITE_MEM commands)there is no START_MON command coming out from PC. Also I was not able to find a code in Inst166.a166 that sets up interrupt table when monitors starts not from 0. Where is my mistake? Thank you.
