Linker error for Interrupt entries

[dparikh]

Hi All,

I am introducing one interrupt for SMU in my project for TASKING compiler. 

IFX_INTERRUPT(SMU0_ISR, 0, 0x1)
{
/* Enable Global Interrupts */
ENABLE();
smu_isr_status = 1;

}

upon building the file I am getting compilation error as below:

ltc E112: cannot locate 1 section(s):
ltc I455: requirement: 0xa bytes of ROM area in space mpe:vtc:linear
ltc I456: section type: absolute restriction - at address 0xa00f0020
ltc I457: .text.inttab0.intvec.001 (178) (0xa bytes)
ltc I428: binding locator symbols (task1)
ltc I429: evaluating expressions (task1)

Could you please help to resolve the error. 

Linker used: tc33x.lsl

Hi dparikh,

I think you may modify as below:

/* ISR declaration. The Macro expands to the assembly code with jump instructions to the function */

IFX_INTERRUPT(SMU0_ISR, 0, 0x1)

/* Function definition */

void SMU0_ISR(void)
{
  /* Enable Global Interrupts */
  ENABLE();
  smu_isr_status = 1;

}

Please let us know if this works.

Regards,

Prudhvi.

Hello @Prudhvi_E ,

Thank you for the reply, I tried as below but still facing the same error.

void SMU0_ISR(void);

IFX_INTERRUPT(SMU0_ISR, 0, 0x1);

void SMU0_ISR(void)
{
/* Enable Global Interrupts */
ENABLE();
smu_isr_status = 1;
}

Error:

ltc E112: cannot locate 1 section(s):
ltc I455: requirement: 0xa bytes of ROM area in space mpe:vtc:linear
ltc I456: section type: absolute restriction - at address 0xa00f0020
ltc I457: .text.inttab0.intvec.001 (178) (0xa bytes)
