FAULT_CODE_DRV

I recently bought a VESC6.  Out of the box it has been flashing the red led 3x.  To find out what was going on I went to the terminal mode and typed "faults"

The VESC returns two lines with regard to faults (it returns other lines too which I don't think are pertinent to the issue)

One says: FAULT_CODE_DRV

the other says: DRV_8301_FAULTS: No DRV8301 faults

It appears that this FAULT_CODE_DRV is keeping me from fully configuring the VESC.  What does this code mean and how do I clear it?

I am getting the same issue with a VESC 4.xx. All it says is

Fault : FAULT_CODE_DRV

Current : -0.5

Current filtered : 0.1

Voltage : 25.20

Duty : 0.011

RPM : 0.3

Tacho : 128292

Cycles running : 2

TIM duty : 554

TIM val samp : 277

TIM current samp : 24859

TIM top : 49165

Comm step : 4

Temperature : 22.45

 

I re-did the firmware in case of a misconfiguration and I am able to use the arrow keys to power the motor for a moment, and then I will get faults codes and cannot spin up the motor.

Problem Solved:  I flashed the VESC6 using the ST link V2 tool.  (BTW I had do connect ALL the SWD connections, including reset and VCC, to get it to work).  Once the part was flashed with the boot loader and code, I attached it to VESC tool and loaded the most recent code.  Fault condition was removed and, after some twiddling of parameters, I was able to get it to do its self discovery and run in FOC mode.
