#84195 - Any unused functions in your program? Responding to: ???'s previous message |
The problem may not be in your routine if you have any uncalled functions in your program. The linker does not ignore uncalled functions - it cannot overlay them because it wouldn't know if it could, so the variables get added to the Data group space.
This was a huge problem for me when I tried to trim the fat out of Atmel's MP3 player software. Once I figured out what was going on, I had to create an if block that called all of the unused functions and make sure that it never evaluated to TRUE. That was a quick way to get aroung the problem without removing the code. FYI, the latest version (7.1) of the Keil LX51 linker has a directive called REMOVEUNUSED, which will cause all unused functions to be ignored and not assigned any data address space. Why they couldn't add this feature to BL51 I don't know - it would be very useful. |
