ARM926 Interrupt exception

Note: This was originally posted on 27th August 2009 at http://forums.arm.com

Hi,

I would like to program an interrupt handler for ARM926ej.

According to reference, when CPU is interrupted, it jumps to address 0xFFFF0018 (interrupt vector).

Then, I suppose I have to program a jump instruction to my handler in that address. But I don't know how.

I'm using GNU toolchain.

Thank you very much
Ricardo

In other words,

Which is the best method to branch from high mem to low mem? Now I'm using "bx r0". But previously I have to calculate absolute address in r0.

Thx
