switched to non-secure mode by setting the secure configuration register
Eh... no. It's kinda confidential.However, in terms of interrupts there is nothing too special about it. It uses the A9's in-built interrupt controller. We have a mix of secure (FIQs) and non-secure interrupts (IRQs) being generated, not seen any problems.
Yes. Didn't really hit any problems (was using a custom system made with the Fast Models tools, not the RTSMs).
