Cannot communicate with Zio gimbal, says FW version is 0.0.0.OFFICIAL and gimbal is OFF

Hello,

When I run gSDK, I am unable to read parameters and obtain motor control functionality on my Zio gimbal.

I have confirmed that all firmware on the Zio is upgraded (running Gremsy Zio payload Firmware v780 Official, and SOM firmware v2.0.1). I am running gSDK on a jetson running Ubuntu 20.04.

I am directly connecting the Jetson to the gimbal control cable over USB/UART. Camera powers on and zeroes just fine.

Here is a condensed version of the output I am receiving:

OPEN PORT
Connected to /dev/ttyUSB0 with 115200 baud, 8 data bits, no parity, 1 stop bit (8N1)
