Question

我正在尝试访问以下功能

     err = SetupForFlash();

该函数是用blackfin.c编写的。

ERROR_CODE SetupForFlash(void)
{   
    unsigned imask_value;

    imask_value = cli();                /* disable interrupts */ 

    /* set clock multiplier and CCLK and SCLK divider */
    *pSIC_IWR |= 0x0001;                /* enable PLL wakeup */
    *pPLL_DIV  = ((CCLK_DIVIDER & 0x3) << 4) | (SCLK_DIVIDER & 0xF); 
    *pPLL_CTL  = (CLOCK_MULTIPLIER << 9) & 0x7E00;    /* set new clock multplier */
    ssync();
    idle();                             /* wait until PLL settle down */

    /* enable async memory banks and defines timing/waitstate */ 
    *pEBIU_AMBCTL0 = 0x7bb07bb0;
    *pEBIU_AMBCTL1 = 0xffc27bb0;
    *pEBIU_AMGCTL  = 0x000f;            /* enable all external memory banks */

    /* */    
    sti(imask_value);                   /* enable interrupts */

    return NO_ERR;
}

原型在blackfin.h中如下

ERROR_CODE SetupForFlash(void);

我在irq_software.c中使用该功能我包含了带有原型的头文件blackfin.h 但我得到一个警告，该功能没有完整的原型

这是blackfin.h的标题

#define __ERRORS_H__

        NUM_ERROR_CODES,
}ERROR_CODE;

ERROR_CODE WriteFlash( unsigned long ulOffset, int nValue );
ERROR_CODE GetSectorNumber( unsigned long ulOffset, int *pnSector );
ERROR_CODE GetSectorStartEnd( long *lStartOff, long *lEndOff, int nSector );


#endif // __ERRORS_H__

Answer 1

可能__ERRORS_H__由系统包含。使用__MYERRORS_H__进行测试。

函数没有完整的原型编译器错误
