Illegal Instruction Exception

Pragathi Simha

Hi I am using iND13400SAA controller.

But in the it's using Armv8-R AArch32

I see in your manual, that Divide by zero is not supported.

I tried creating floating point exception , even that is not supported.

Is there a way to trigger illegal instruction exception, so that i can verify that Exception_ISR configuration.

    Hi,

    Thanks for the reply.

    I tried to load an illegal address to a register as below.

    This will trigger Data abort exception, 

    I even checked in manual they had mention

    So when i tried 

    Software didn't cause UND exception

    I even tried to mov PC, this caused prefetch exception

    So is there any other way where i can test for UND exception?
