PCIe Linux driver for Cyclone 10GX Gen 2, 1 lane

[CaptainPrice15]

Hello,

I wish to connect the Cyclone 10 GX using 1 lane of PCIe 2.0 with an MCU that runs Linux. Is there any Linux Driver readily available for this purpose? The application interface of the IP would be either Avalon-ST or Avalon-MM. From the MCU side, only one PCIe gen 2 lane is available.

Hi,

The driver for Cyclone 10 GX Avalon Streaming Hard IP for PCIe and Avalon Memory-mapped Interface for PCIe are available in Windows version only.

For Cyclone 10 GX FPGA – PCIe* 2.0 x4 DMA reference design,

• you may find the Linux driver in https://www.intel.com/content/www/us/en/design-example/714945/intel-cyclone-10-gx-fpga-pcie-2-0-x4-dma-design-example.html.
• After unarchiving the par file, you will see the AN829_driver.tar file in the driver folder.

Hello Wincent,

Thanks a lot for your reply. If there is no Linux driver readily available from Intel, would you suggest something from any other source. If not, could you please help in in understanding if any special requirements are there for developing a Linux driver for supporting the Avalon-MM or Avalon-ST hard IP for PCIe or would a standard PCIe driver do the job?

Hi,

I wish to follow up with you about this forum case.

Do you have any further questions on this matter ? Else do I have your permission to close this IPS ticket ?
