The Xillybus Forum

This is the same answer, translated into Chinese, as some have asked:

这些 LED 的含义如下:

GPIO LED 0： Heartbeart。这个 LED 一直闪烁。
GPIO LED 1： 表示从 FPGA 到 CPU的数据传输
GPIO LED 2： 表示从 CPU 到 FPGA的数据传输
GPIO LED 3： 表示 FPGA 正在等待数据从 CPU 到达 FPGA。换句话说,至少有一个未完成的读取请求。当 Xillybus的逻辑复位时, LED 也可能处于开启状态。

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).

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.
