Hello,
Actually documenting that part somehow slipped away. So let this be the place it's written down:
GPIO LED 0: Heartbeart. Just blinks.
GPIO LED 1: Indicates transmission of data from the FPGA to the CPU
GPIO LED 2: Indicates transmission of data from the CPU to the FPGA
GPIO LED 3: Indicates that the FPGA is waiting for CPU-to-FPGA data to arrive (i.e. there's at least an outstanding request for reading) OR that the Xillybus logic is held reset (on some platforms).
Regards,
Eli
