LED function on Xillybus PCIe?

Postby mwayne » Tue May 04, 2021 2:13 pm

Hello,

Is there a link that explains the function of the 4 LEDs in the PCI express version of Xillybus? I found the one for XillyUSB, but can't seem to find the PCIe.

Thank you.

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
