BL51: Batch File for Banked Applications

Information in this article applies to:

  • C51 All versions


How do I make batch files to build a banked application?


The following are examples of batch files used to build a banked application. Note that the last file requires a fair amount of customization.

@echo off
REM  usage:
REM        compile filename [C51 Directive list separated by spaces]
c:\c51\bin\c51 %1.c %2 %3 %4 %5 %6 %7 %8 %9

@echo off
REM  usage:
REM        link
c:\c51\bin\bl51 @build.lnk

In the following, each object file must be replaced with the real object files from your project. Consider that each bank may have more than one object module. Additional directives must be added to the end.

B0{file.obj,file1.obj}, &
B1{file2.obj}, &
B2{file3.obj}, &
to output &
RS (256)

Place additional directives here. Be sure to note that bank location directives are encapsulated in parenthesis ().


  • Refer to BANKx in the BL51 User's Guide.
