I am working on a project in which i am using at89c2051. When I wrote a program and built it using c51 the following message was displayed:
Build target 'Target 1' linking... *** WARNING L1: UNRESOLVED EXTERNAL SYMBOL SYMBOL: ?C_START MODULE: STARTUP.obj (?C_STARTUP) *** WARNING L2: REFERENCE MADE TO UNRESOLVED EXTERNAL SYMBOL: ?C_START MODULE: STARTUP.obj (?C_STARTUP) ADDRESS: 080AH Program Size: data=9.0 xdata=0 code=15 "L2" - 0 Error(s), 2 Warning(s).
Ignoring this I decided to simulate the program but the register values were not being displayed. Why is this happening? Is there any problem in the startup.a51 file?
Thanks a lot to you guys. I removed startup.a51 from my program and it is running now.
