How to update VESC firmware?

Anybody have detailed instructions of how to update their firmware on a Maytech 200A VESC? I’ve got a problem with my VESC and hope that its a firmware problem. Thanks. -Marc

I used the following link to help me update my firmware. Seemed to work just fine.
Unfortunately, it didn’t solve the problem. I posted it in another thread but I’m not getting any power to the motor. The motor wizard in VESC Tool seems to work fine but nothing happens to the actual motor.
Tried it on two different motors so it must be the ESC. Any ideas?
