Bricked Core2

Re: M5Stack Core 2 appears to be bricked

Hi all, I think that I've really bricked my Core2. I tried to install a program from M5Burner upon initial power up of my brand new Core2. When that didn't work I tried going back to Core2FactoryTest, but now I'm not getting that to work. When I connect to the Serial Monitor, I see this error:

[FROM M5Burner] COM5 opened.
Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled.

Rebooting...

Any thoughts?

Interestingly enough I'm able to burn and run the M5Core2 TouchPanel Recovery and Core2_For_AWS. I'm wondering now if there is a bad memory chip.
