Interrupt Handling

Hello,

            Can any one help in handling INTERRUPTS in MPC8323E-RDB Board.? I am using a PC with Ubuntu 8.10 with the kernel 2.6.27. I am loading a kernel image of version 2.6.20.6 into my development board. I am trying to writing a device driver for an external uart XR16L784 and able to access data read and write without IRQ Handler. Now I want to add IRQ Handler to access data in and out. I written a small piece of handler code but control is not going into IRQ Handler. Are there any settings required on either processor or external Uart side to set interrupts.? How to enable external interrupts in processor.? How to know my handler is called or not.? I already enabled interrupts in Uart control registers.

 

Please, respond as soon as possible.

 

Thanks and Regards,

Siva Prakash Reddy Narreddy
