Dear all,

Previously i implemented application successfully using CCS compiler. Now, I am using the same TMS570LS USB development board with IAR compiler.

In this i dont know how to represent this INTERRUPTand SWI_ALIAS for IAR compiler. Always i got the warning as Unrecognized #pragma.

I mention one sample line used in CCS compiler below,

#pragma INTERRUPT(sci1HighLevelInterrupt, IRQ)

and

#pragma SWI_ALIAS(INT_ENABLE,          4)

Anyone could tell me how to modify as per IAR compiler.

 

Thanks and Regards

    Hi Gowdham,

    Please use __irq to define irq ISR,  __fiq for fiq ISR, and __swi for SW interrupt. for example, __irq__arm void myINT(void)

    Regards,

    QJ
