C51: IDENTIFY UNCALLED LIBRARY ROUTINES
Information in this article applies to:
I have an application where I am getting several Linker warnings:
*** WARNING L16: UNCALLED SEGMENT, IGNORED FOR OVERLAY PROCESS SEGMENT: ?PR?_EPROMWRITE?I2C
It appears that the segments refer to some library code that is indeed not called. Is there a way to verify that?
Also what do I need to do to remove these warnings.
You can verify the usage of functions using the linker cross reference listing section which is enabled in µVision under Project - Options - Listing - Linker Listing - Cross Reference.
For libraries it is important that each function that can be used individually gets its own source module. Structure your library this way to remove the warnings.
