Here's a rough drawing of our Raspberry Pi prototype system:

 

Our PCIe controllers (Version 1 and Version 2) are standard PCIe x1 PCBs with golden finger that can plugged into Windows PCs.

 Version 1, works on Windows PCs and gets detected by Raspberry Pi (lspci)

Version 2, works on Windows PCs and does not get detected by Raspberry Pi.

Hi JBayl ,

The picture is clear for me to understand the system setup.
May I know what is the different between Version 1 vs Version 2 ?
Is it different device or ?

Regards,
Wincent

    Version1 uses NXP's PX1011B PCIe X1 PHY with an interface to a Cyclone 3 FPGA.

    Version2 uses a Cyclone10Gx FPGA.  No external PHY.
