The boot3 file you mentioned is correct!
Actually I am using 11.059Mhz crystal. Would it affect much? Today I run a testing on my design. Whenever I press reset button, at Hyperterminal window will pop up character f. I assume that this is a hexadecimal character. The testing is running at 4800bps. Upon this testing, was this mean that the communication between MCU and PC is success? When I measure ALE pin, there is a wave form but looks like very distorted square wave. And when I press reset, the wave gone and return again. Is this meaning that the reset circuit is correct? Once hyperterminal is connected, I can't see any greeting of Steve's 8051 bootloader - 18 April 1995 Download Intel hex files to address 8000h My Rom is addressing from 0000 to 7FFF and Ram is at 8000 to FFFF |
