IVOR4_Handler AND vPortISRHandler

Hi,

i am using mpc577c evk board. I developed drivers per our requirements and also Freertos integrated in my project.

But i am facing issue that freertos is jumping to vPortISRHandler when a tick generates (which is in    interrupt vector.s and portasm.s file).

since in interrupt_vector.s file i found small code snippet.

IVOR4_Vector:
#ifdef USING_OS_FREERTOS
e_b vPortISRHandler
#else
e_b IVOR4_Handler
#endif

 

 

For Freertos to run need the macro to be defined. but for normal interrupts the macro defined not required. when the macro is defined normal interrupts are not working going to lock stage(swt1_handler).

i need freertos and also some of the input interrupts to execute.

Can anyone help me regarding this issue.

Thanks,
