QUESTION

How can I increase the speed of the data overlaying? I have a large number of pointers to function tables and it is taking a long time to link my project.

ANSWER

Use the linker SPEEDOVL directive (abbreviation SP). The linker ignores all references to constant code segments when performing the data overlaying.

A side effect is that the linker might not detect all forms of illegal indirect function calls.

You may specify the directive in one of the boxes under the Additional tab in the BL51 Code Banking Linker Options in uVision.
