VESC tool, motor not spinning (clicking/grinding)

I have a FSESC 7550 and a Torqueboards outrunner motor. I connected the two and ran the VESC setup, which worked fine (the motor spun up). Then, when I try to use the arrow keys to simulate throttle within the VESC tool, the motor makes electrical buzzing and clicking sounds and doesn’t spin. What can I change to make the motor work properly?

Here are videos of the issue. The first video shows what happens when I try to use the arrow keys to turn the motor, which buzzes and clicks instead of spinning. Automatic duty cycle ramp also causes the same issue: https://drive.google.com/file/d/1hrb2L3ythgxE9jHij7LoVcSMwI5dhSjk/view?usp=sharing

The second video shows that, interestingly, when seeing which motors are inverted, the VESC tool spins up the motor properly. https://drive.google.com/file/d/1hvkmWwE64SiNHhSHvJGhokos0d6Vdrh0/view?usp=sharing

I’ve tried setting up the motor both with the hall sensors connected and disconnected, and it causes the same behavior each time.

I solved the problem.

For the first case, to get the arrow keys working in the VESC tool, I went to the left sidebar App Settings → General → APP to Use → select “UART”. Mine was set to “PPM and UART”. Changing immediately gave me keyboard control of the motor, and the VX2 started working as well.
