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
get_core_id mov r1, #0 mrc p15, 0, r1, c0, c0, 5 ubfx r0, r1, #8 #8 bx lr
--Log
core_id 0
core_id 2
core_id 3
core_id 4
core_id 5
core_id 6
core_id 7
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?
