XVC PCIE Binary Fails to Connect to device

[ChrisKjellqvist]

Hello
I'm trying to connect to the ILA inside my CL. I've followd the instructions from here.
When modifying the PCIE Vendor/Device ID in xvc_pcie_user_config.h, I've tried the one in the link above and both ID pairs given from aws ec2 describe-fpga-images for my FPGA image:

"PciId": {
    "DeviceId": "0xf010",
    "VendorId": "0x1d0f",
    "SubsystemId": "0x1d51",
    "SubsystemVendorId": "0xfedc"
},

Regardless, once I've successfully added the kernel image, running sudo ./xvc_pcie results in the following:

ERROR: Failed to Open Device
ERROR: Opening JTAG port failed

Description:
Xilinx xvc_pcie v2024.2
Build date : Sep 20 2024-09:46:41
Copyright 1986-2018 Xilinx, Inc. All Rights Reserved.

ERROR: Failed to Open Device
ERROR: Opening JTAG port failed
Exiting xvc_pcie application.

This is despite having loaded an FPGA image with an ILA core on it.

Any idea with where to go from here?

Hi @ChrisKjellqvist,

Thank you for reaching out with these errors using the XVC application. The XVC driver should attach to a static vendor:device ID, referred to in the documentation:

    #define PCIE_VENDOR_ID  0x1D0F // Update to use PF1 for Virtual JTAG
    #define PCIE_DEVICE_ID  0x9248 // Update to use PF1 for Virtual JTAG

I think the confusion may be that you've replaced the 0x9248 with 0xf010. If this solution still doesn't work, please share the lspci -vvv output of the FPGA device you're trying to attach to.

Please let us know if this help!
