Dear all,Can you help me?Thank you in advance! I used uVision(Keil C51 V7.01) to connect to Monitor-51 which was made by myself.But it didn't work.When I built my project,it showed as below: Build target 'Target 1' assembling mon51asm.a51... assembling STARTUP.A51... linking... *** WARNING L5: CODE SPACE MEMORY OVERLAP FROM: 8000H TO: 8013H *** 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: 801EH Program Size: data=9.0 xdata=0 code=32803 creating hex file from "mon51test"... "mon51test" - 0 Error(s), 3 Warning(s). Then I started debug session in spite of the warnings,it show "ERROR 22：NO CODE MEMORY AT 0x8000".And the uVision couldn't connect to Monitor-51.How should I solve this problem.Thank you very much for your advice.
I use At89S52 and external memory(62256) for my code.
