IPA for File or Program Option

[Geek19]

Hi,

I am compiling a code with two IPA options which are File and Program options. The first option compiles with no error or warning for FLASH but the second option that is Program, generates 2 warnings for FLASH compile as follwos:

//-----------------------

FORCEACTIVE symbol 'bam_rchw' is either not a global symbol or doesn't exist.  Ignored.

FORCEACTIVE symbol 'bam_resetvector' is either not a global symbol or doesn't exist.  Ignored.

//-----------------------

These situation prevents the code to run as an stand alone entity!? ( It runs with debugger in control!) is there any way to fix this probelm?

I am running CW IDE 2.7 Professional  on windows 7

Thanks;

Hello Geek19,

I'd suggest you to change the bam_rchw and bam_resetvector declaration in MPC55xx_init.c file. Please try to add

__attribute__((force_export)) prior to declaration and rebuild. This should avoid deadstripping of these two symbols due to IPA Program optimization.

/**************************************************************/
/* RCHW and Reset Vector setup:                               */
/*   The chip is by default setup to boot from internal Flash */
/*   and the watchdog is disabled.                            */

typedef void (*resetfuncptr)(void);

#pragma push /* Save the current state */
#pragma section const_type sconst_type ".__bam_bootarea"
__attribute__((force_export)) extern const unsigned long bam_rchw;
__attribute__((force_export)) extern const resetfuncptr bam_resetvector;

Anyway the FORCEACTIVE  keyword in .lcf should do the same so I'm going to log a Linker defect into our defect tracking database.
