base image configured with JTAG can’t communicate over PCIe

We are having issues when writing a partial reconfig image to the FPGA over PCIe. It looks like the base image configured with JTAG can’t communicate over PCIe. The issue persists after a soft reboot following configuration. lspci shows the device.

after following"Initializing the Intel Arria 10 GX FPGA Development Kit for use with OpenC" instructions flashing "aocl flash acl0 boardtest.aocx"

"aocl diagnose" passes.

but then following the OpenVino Install linux with FPGA instructions

The outputs from the program step and a subsequent diagnose attempt are below.

                       Failed initial tests, so not working as expected.

                       Please try again after reprogramming the device.

Found no active device installed on the host machine.

Please make sure to:

      1. Set the environment variable AOCL_BOARD_PACKAGE_ROOT to the correct board package.

      2. Install the driver from the selected board package.

      3. Properly install the device in the host machine.

      4. Configure the device with a supported OpenCL design.

      5. Reboot the machine if the PCI Express link failed.


Any suggestions on what may be the issue, could it be the pci drivers on centos 7.4?

One thing you should try is:

lspci -vv 1172:2494

You should see "aclpci_a10_ref" and "aclpci_a10_ref_drv". If not, then it is a driver issue.

Let me know your results and we can proceed from there.

Kind Regards,

Monique Jones


After lspci -vv
