hi,
I use Keil uVision4. I got the sample code 8051_BITIO.ZIP on Keil website http://www.keil.com/download/docs/84.asp
and ,I got HEX file via excuting compile.
I want to confirm Mapfile for code location.
Which is the file for address map in project directory?
Yes, the Linker controls allow you to do that - for details see the Linker manual.
Note that the free evaluation version imposes certain restrictions on the code start address:
