I was wondering if anybody got a c166 to run the debugging at a baudrate higher than 57600baud? if the program becomes large it is odd to watch the loading process rising in 5% steps. i gave the 115200baud a try but it might come from the deviation error and thus didn't work:
f_cpu = 20MHz; S0BRS=0;
with S0BRL=4 i get 125000baud (which is 8%) with S0BRL=5 i get 104167baud (which is 9.5%)
is my calc correct? is there anything else i missed to set/check?
a much harder task is to change the xtal frequency or the scaling factor to suit the software debugging speed of 115200baud as you probosed. that's true.
