Program flash: Segment overflow: .p_Code for MC56F8345 with CW 7.3

Hi,

I am a newbie trying to compile a project on a MC56F8345.

I'm using CodeWarrior version v.7.3 with Processor Expert.

I get this error when linking:

"Link error: Segment overflow: .p_Code

I know a have only 128Kb on program flash

But on my projet I saw on my project view (.mcp)

- User Modules is using 77K

- Support is using 47K

Is this normal that those 4 libraries using 47K of the program flash

- MSL C 56800E.lib (44186)

- MSL C 56800E lmm.lib (n/a)

- Runtime 56800E.lib (4526)

- Runtime 56800E lmm.lib (n/a)

Did someone have a hint to optimize program flash memory?

I know my program is big, but i don't realize CodeWarrior will take so much of the 8345 .

Thank you.

J2MEJediMaster added MCU type and CW version

Have you tried any of the compiler/linker optimizations? The linker should strip out unused functions from the libraries.

Thank's

Its working!

I change optimize for smaller code size with Level 1, and now i reduce my code to less than 128Kb.

It was so simple. I change all my bean from speed to code size optimization.

Also I remove some debug instruction with this compiler directive: #define NDEBUG
