Hi there,
I'm working on altera cyclone V SoC equipped with a Dual Core Cortex-A9. It runs Linux socfpga 3.13. I'm trying to disable (and enable) the SCU at runtime, but I have a segmantation fault: unable to handle kernel paging requet at virtual address FFFEF1000.
I think that the conversion from virtual to physical address deny me to access a the SCU Control Register. Obviously, I cannot disable the MMU because I cannot flush caches.
Can anyone help me? How can I proceed?
Thanks in advance.
MI
