Vesc tool won't connect vesc to motor

Please could someone give me an idea whati s going on. 

FW:3.38 HW:410 (I have noticed that vesc says 4.12 on front of it however vesc tool says its 410, not sure if this is a problem)

It is a sk8 vesc with a KEDA 200kv BL motor

I has been working fine for the last month on the bench however now it wont connect to motor.

On FOC motor detect it takes about a minute or two for RL (the red led starts to flash 3 times every 10(ish) seconds) then says R=0, please measure first.

I have tried re-flashing firmware. I cant get the motor to do anything.

On RL detect it does vibrate and calculate L but says R=0

That looks like the DRV chip might have been damaged. Try to replace the DRV chip and see if that helps?

410,411,412 are nearly identical and use the same Firmware.
