Interrupt Problem

Hi jayesh, donq!

Sorry I was on a trip yesterday.

so its right,problem occurs because of other thing not this.

This might be true, I can't know it for sure.

But alt_irq_enable(nfc_base); is not the right call to alt_irq_enable().

Take a look the HAL API Reference.

--- Quote Start ---

int alt_irq_enable (alt_u32 id)

--- Quote End ---

And with id it is meant to use <YOUR_MODULE_NAME>_IRQ. This is the id which also specifies the priority of your interrupt, at least with the LEGACY Interrupt API.

I am pretty sure with this, because I've used the interrupt API quite a time.

@donq:

Lots of altera macros are written based on the _BASE address of the device.

That's true. But in general all MACROS are defined with big letters. And alt_irq_enable() isn't. It is a function call.

--- Quote Start ---

but I'd assume that alt_irq_enable() is such a macro

--- Quote End ---

No, it isn't. Maybe it is a INLINE function, I've to check on monday at work. But it is not a MACRO.

Have a nice weekend!
