BL51: Overlaying Bit-addressable Segments

Information in this article applies to:

• C51 All Versions

QUESTION

How do I instruct the BL51 linker to overlay bit-addressable segments?

ANSWER

Unfortunately, that feature is not supported in C51 Version 5.x. It may be added in a future version of the 8051 tools.

As a work-around, you can manually overlay the data using the BL51 DATA directive. For example:

BL51 ... DATA (file1?BA (20H), file2?BA(20H))

BL51 will generate a warning that you may safely ignore.

MORE INFORMATION

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