hi,all
I want to use core timer interrupt, and I use "request_irq(IVTMR, Timer_irq_handler, IRQF_DISABLED, "Timer IRQ",NULL)" to request and add Timer_irq_handler on it. But system show me: IVTMR is undefined. In fact I have included <asm/irqs >.
My cpu is bf537.
Why? Pls give me aome advice. THANKS!

you cannot use the core timer. the core architecture already utilizes it.
if you want a periodic timer, then use the normal Linux timer framework.
