imx6: Using secure interrupts

Question asked by 42Bastian Schick on Apr 30, 2015

is there any special handling needed on i.MX6 to enable secure interrupts?

When I set a bit in ICDISRn, the corresponding interrupt is not serviced any more.

As soon as I switch it to non-secure, it works again.


I also tried to set FIQen, but also no FIQ arrives.


The CPU is (as out of reset) in secure mode, therefore I'd expect the interrupts to be serviced normal.
