Rock64 board seems defective, how to confirm?
#1
Hi all!

I have a 4GB Rock64 that has never been able to run any image for more than a few minutes without a kernel panic or a complete freeze. It usually happens within seconds of booting. At first I assumed I had just been unlucky with my image choices, but over the past few days I've gone through probably a dozen different images, Linux as well as Android, and nothing seems to work (though Android images typically run ok right up until the mouse cursor shows up on the screen). I'm booting from sd and I've tried two different cards. Is there anything else I can try that would possibly get this working? Any recommendations for a super-stable image to try? Or something like a memtest image that could help me diagnose the problem?
Unfortunately I bought this last year so it is no longer under warranty, but I would at least really like to confirm that it is a hopeless case before I throw it out the window.

1. Please check your power supply whether still function properly. If you have scope, check the voltage ripple waveform.

2. Run meemtest is a good way to determine whether DRAM still function well.
