Hi Guys,
I'm just getting into embedded development, and am trying to gain some
traction. I'm running linux as my desktop of choice, and really like this
edsim51 program for simlation. I would use s51, but under linux, the simulator
is command-line and not very intuitive. However, I'm having a hard time getting
programs to run in the edsim51.
Let's say I have a simple c program (main.c):
#include <8051.h>
void main(void) {
while(1) {
P1 = P2;
}
}
I compile the program
sdcc main.c
And copy the .ihx file .hex
cp main.ihx main.hex
I launch edsim51, and I get this error:
Error - Code Overlaps - MOV R1,#00H
About half the way though the disassembled text. Below's the complete text. Any
ideas?
