OMAP-L138 EMIFA irq

Yaakov Dalsace
Prodigy 40 points

I want to write a Linux driver on the ARM which will receive the interrupts from the EMIFA (pins EMA_WAIT0/1).

From sprugm7d.pdf table 12-1, I understand that the interrupts (both? not clear to me) are redirected to the vector 14.

How I get the interrupt?

Is there a sample code which could help me?

 

Thanks!

Yaakov

    Yaakov,

         You'll need to configure the ARM interrupt controller (refered to as AINTC in the documentation) to route the EMIFA event into an interrupt to the ARM. The AINTC is well documented in the Device's System Reference Guide.
