Thank you for the input! The target device is a KSZ8695X with a 20 pin ICE connector. It has its own external power supply and the status lights are up. I tried unplugging the cable from the target completely and running again, and got the same error. The Olimex debuggers light stays solid yellow when I run the openOCD command, where before it was turning red.
