Interrupt issue in RSK +RX65N KIT using FIT modules

$

Hello,

I am using an RSK + RX65N development kit. I am porting RTOS to the kit.

My basic task involves taking an input from the switch button and turn ON an LED. I am facing issue in generating an interrupt from the switch using FIT modules.

Procedure followed:

 - Tested a working project and started making changes in that project

 - Imported FIT modules for the switch interrupt using details from the schematic available from Renesas. Assigned IRQ8, IRQ9, and IRQ15 according to the schematic for each switch

- used the following code to configure the switch interrupt,

R_ICU_PinSet();

ucIntError = R_IRQ_Open(IRQ_NUM_8, IRQ_TRIG_FALLING, IRQ_PRI_0, &SwitchHandle3, Switch_ISR);

ucIntEnableError = R_IRQ_InterruptEnable (SwitchHandle, true);

 

- Both the values, ucIntError and ucIntEnableError, are returning 0 from the functions. So the interrupt is getting configured but when the switch is pressed, it does not execute the code in Switch_ISR function. 

 - Removed the RTOS part and checked but the issue is with interrupt only.

 - Tried the FIT demo project file as well, they seem to cause the same problem. 

 

Also, it was checked whether the controller execution jumps to the irq8_isr but it did not. 

 

Could you please give any input on this?

 

Regards,

Pratik
