Hi! I've been working with a DRV8301-HC-EMV with a F28069 Control Card for a few weeks and managed to get my application running after some grief, but now when i try to run it it behaves erratically, out of nowhere. I tried running the original Lab02b example project and it misbehaves too so I conclude something must be wrong with the board. I'd appreciate any help in debugging the problem, I'll write down the symptoms and what i already tried:
When I tried the Lab02b example, it'd start identifying the motor, but in the ES_State_Ls it'll start spinning out of control (it didn't use to do this before). When i try my project (based on the lab12b example) It does the Rs measurement, but when it does it consumes a tremendous amount of current and makes scary noises.
What i tried:
Checked all connections and they are fine, measured the resistance of the motor coils and they are all correct, there's no leakage to the case. Power supply is stable and well connected.
I reseated the control card in the socket, no dice.
