Converting the HVPSFB EVM to F28069 MCU

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

I'm converting the HVPSFB EVM software package to the F28069 MCU on a new PCB, and get two linker error that I find difficult to solve:

1. unresolved symbol _Comp, first referenced in ./DAC_Cnf.obj HVPSFB_PCMC

2. unresolved symbol _ePWM, first referenced in ./PWM_PSFB_PCMC_Cnf.obj HVPSFB_PCMC

I'm not able to determine in which file these structs are defined:

**

// Used to indirectly access all Comparator modules

volatile struct COMP_REGS *Comp[] = ..........

**

// Used to indirectly access all EPWM modules

volatile struct EPWM_REGS *ePWM[] = ........

**

 

Best regards

Consul

    Hello Consul!

    I'm not sure but perhaps you need to define within your main file:

    Variant 1

    volatile struct EPWM_REGS *ePWM[8] = {&EPwm1Regs, &EPwm2Regs, &EPwm3Regs, &EPwm4Regs,

    &EPwm5Regs, &EPwm6Regs, &EPwm7Regs, &EPwm8Regs};

    volatile struct COMP_REGS *Comp[3] = {&Comp1Regs, &Comp2Regs, &Comp3Regs};

    Variant 2

    extern volatile struct EPWM_REGS *ePWM[];

    extern volatile struct COMP_REGS *Comp[];

    Also perhaps you need to include to project this library: 

    ti\controlSUITE\device_support\f2806x\v136\MWare\rts2800_bl\Release\rts2800_bl.lib

     Regards,
