Unable to upload firmware to Pixhawk 6c

This is my 1st drone project and I am getting off to a shaky start. I am using the Pixhawk 6c with the s500 v2 devkit from holybro. I have tried updating the firmware on OSX as well as Windows and have also tried various cables. Still no luck and am getting the same error each time.

getBoardInfo failed: "Sync: Send Command: Get Command Response: Timeout waiting for bytes to be available"

Upgrade Cancelled

A deeper dive from the console shows this:
FirmwareUpgradeLog: open: "cu.usbmodem01"
"Auterion" "PX4 FMU v6C.x"
FirmwareUpgradeLog: 0 "Pixhawk"
FirmwareUpgradeLog: getBoardInfo failed: "Sync: Send Command: Get Command Response: Timeout waiting for bytes to be available"
FirmwareUpgradeLog: PX4FirmwareUpgradeThreadController::cancel
FirmwareUpgradeVerboseLog: _cancel
FirmwareUpgradeLog: reboot
LinkManagerLog: New auto-connect UDP port added
LinkManagerLog: allocateMavlinkChannel 1
LinkInterfaceLog: _allocateMavlinkChannel 1

If you have any suggestions for how to move forward, please let me know.
