I'm trying to get all core id for multi core on A65 in Firmware code..
mrc p15 #0, r0, c0, c0, #5
Especially, I get core id in assembly
mov r1, #0
mrc p15, 0, r1, c0, c0, 5
ubfx r0, r1, #8 #8
But unfortunately core_id 1 never appears. I think PE1 is stuck somewhere but don't know inside.
Would please guide me if all core id is not working (some core id is not responding), what am I supposed to do?
Is there any way to find the reason why PE1 is not responding? how would I debug this?
