Greetings! My first post here. I have an older v5.9(ish) Gen3 Servocat from 2013 that I'm trying to upgrade the firmware to the newest (7.0). Its on an Obsession UC22. I'm following the instructions word for word in the manual; power off, flip switch to Upgrade, move jumper to both pins, open RFU, choose correct com port, serial to USB connector, set affinity to 1 processor, turn on power to servocat, load firmware, and I get this error. I've tried with and without Argo Navis turned on. With and without all the other cables connected. 2 different USB cables. 2 different laptops. Multiple different com ports (all under 8), different baud rates on the port and in RFU, compatibility mode for RFU (both laptops are Windows 11). I get a green "connected" in the ServoCAT-Sky software. In regular mode on PCB and Argo Navis turned on SCU in the command prompt is able to connect (but because it's an older version, there's no data). I've run out of ideas on things to try, I don't have an old windows 7 laptop sitting around to try that, but I haven't heard of this issue before. Anyone out there have any experience with this? Help!
