rock64, compile problems "illegal instruction", "memory fault" -> ddr_333Mhz?
#5
Year ago there was 400/600 in DMC (you can try older kernels).

Code:
# cat /sys/class/devfreq/dmc/available_frequencies
400000000 600000000 786000000 800000000 850000000 933000000 1066000000

Never mind. I suppose that you have some fault in your PCB (like "PCB delamination"), memory/rk3328 chip and/or BGA soldering problems. Memory bus is very sensitive to impedance quality. Do you have another RK64 to compare results ? What do you compile (something equals like linux kernel?) ? I have only 1GB versions to test.
I left this community in Aug 2019 due to PINE64 refusal to produce/deliver ROCK64-1G version 3 after more than one year of changing statuses to "planning", "evaluating", "releasing", "availability", "estimated availability" and finally "no schedule" Angry. ROCK64 is dead platform without any advantage. Buy Raspberry PI 4 !
Away
