Hello
I was derived here from :
https://community.freescale.com/message/473511#473511
My kernel stops loading when I try to access to registers in
mach-imx6q.c. I think it has something to do with iMX6 security system.
Access to that registers at that moment seems to be denied and the
kernel load crashes.
I am looking for how to change that with no luck. I found that dts
configures AIPS registers like this:
aipstz at 0207c000
{
reg = <0x207c000 0x4000>;
};
but I changed it to:
aipstz at 0207c000
{
reg = <0x207c000 0x77777777>;
};
and I yet have not access to read that same AIPSTZ1 register from
mach-imx6q.c
Best regards,
Jose
