Due to the auto adaptation module finite state machine(FSM) in the 25G Ethernet Intel FPGA IP if you turn on the Enable auto adaptation triggering for RX PMA CTLE/DFE mode option during the IP generation, the Transceiver Toolkit operation will be interrupted when the FSM turns on and off background calibration on H-tile production device. Thus you will not see the channel appear in Transceiver Toolkit. For device without background calibration like L-tile production device, the auto adaptation module FSM doesn't contain states to turn on and off background calibration. It will not be affected by this issue.
