If you are talking about http://www.embeddedlogic.com/embarchiv.../boot3.asm , there is enough guidance within this file:
- you should have a program memory starting from 0 prgrammed by boot3.hex, either internal or external (and EA set accordingly); - you should have 12MHz xtal - you should set 2400 Baud (8 data bit, no parity, 1 stop bit) and no handshake! Lian Kok Tong said:
Actually I am using 11.059Mhz crystal. Would it affect much? Obviously, it will affect the Baud Rate! If you haven't adjusted the code to take care of the different clock frequency, the Baud Rate will be wrong - which may well account for hypoterminal not seeing anything. The testing is running at 4800bps. But Jan said 2400! |
