    As far as I know GDB cannot access those registers.
    I'll ask my supervisor if he has access to a good JTAG debugger (probably we could have one lingering around in the department...)
    and will write here what are the values of IFSR/IFAR.

    p.s. I've checked the memory mapping on /proc/$pid/maps and it says that it's correctly allocated with permissions rwxs mapped on "/dev/zero (deleted)"

    Thank you for your kind reply!
