hi,
In the example code snippet from my previous response, the ISR checks all interrupts mapped to IVG7. If multiple interrupts are mapped to IVG7, then inside the ISR, you need to check for the interrupt asserted, in interrupt status(SIC_ISR) register. Please make sure that you program the SIC_IAR and SIC_IMASK registers. Please let me know if this helped solve the issue.
