Link Errors during make of ETPU2 functions + ETPU_GCT + RAppID Code + CW for MPC55xx and MPC56xx 2.10 -> Errors Code: undefined '__div2i'

[henriquemescuan]

Hello,

I am beginner in Freescale applications

In my first application, I am finding problems during linking files with CodeWarrior:

Below is the configuration of my project:

PC: Windows7 SP1 x386 + 4GB RAM + Dual Core M350

MCU: MPC5634M

CodeWarrior: CW for MPC55xx and MPC56xx 2:10

ETPUGCT: 1.4.0.4

RappID: 1.1.0.3

ETPU2 Functions: ETPU WEB Generator (CAM + CRANK + SPARK + FUEL)

Description of the problem:

When I compile my application with basic ETPU2 functions, eg PWM, the CodeWarrior works very well.

But when I insert more complex functions like (CAM + CRANK + SPARK + FUEL), the CodeWarrior return link errors:

Link Error: undefined: '__div2i'

The complete project is attached!

Anybody know how to help me?

Hello Henrique,

Your project is missing the runtime library which contains 64-bit signed integer divide routine "__div2i"  among other .

I'd recommend you to add this library file into your project:

"<CW for MPC55xx and MPC56xx 2.10>\PowerPC_EABI_Support\Runtime\Lib\Runtime.PPCEABI.VS.UC.a"

if you also intend to use standard C routines (e.g. memcpy, sprint...) I'd recommend you to add also MSL library too:

"<CW for MPC55xx and MPC56xx 2.10>\PowerPC_EABI_Support\MSL\MSL_C\PPC_EABI\Lib\MSL_C.PPCEABI.bare.VS.UC.a"

These libraries are part of the CodeWarrior Wizard generated project by default.

I'd also suggest you to update your .lcf file and include .init and .init_vle sections to avoid a linker error. These sections are used by the runtime lib and linker so they should be defined in .lcf file:

   GROUP : { 
         __argv=.;
        __env=.;
        
        .init  : {}
        .init_vle (VLECODE) : {
        *(.init)
        *(.init_vle)
        }

        .text_vle (VLECODE): { 
            *(.text_vle)
            *(.text)
         }
        .text : {  }
        .rodata (CONST): { *(.rodata) }
        .sdata2 : {  }
        .sbss2 : {  }
        __DATA_ROM=.;
} >int_sram

Hope it helps.

Stan
