MMD ERROR while connecting to board

Hi

ive got some troubles setting up an initial Hello World (for opencl) . (windows7, 64)

the current error I get is " MMD ERROR: failed to scan for the PCI device."

this error is appearing when trying to program FPGA with "aocl program" after compiling the kernel file.

aocl program: Running program from D:\altera_pro\15.1\hld\board/windows64/libexec

Setting debug level to 1

Failed clGetDeviceIDs.

Error code: -1

OpenCL Notification Callback: Invalid device specified

Failed clCreateContext.

Error code: -33

aocl program: Program failed.

Any idea what this could be? It shouldn't be a board/PCIe port problem because when i program sof file through JTAG, my host PC can recognition the board.

is the driver not well installed?? or is the mmd library not up to date?

Thanks for any help!

    Check Device Manager, you should see Jungo installed, but you should also see the A10 Reference board under the "Accelerators" group.

    You should also run "aocl diagnose" and see if that passes.

    hi，pnac

    i have install the driver successful, and i also can see Jungo intalled and the a10_ref board under "Accelerators" group.

    but when i invoke "aocl diagnose " ,the error message is printing “MMD INFO : [acla10_ref0] PCIe-to-fabric read test failed, read 0xffffffff after

    1 attempts

    Phys Dev Name Status Information

    acla10_ref0 Failed Board name not available.

    Failed initial tests, so not working as expected.

    Please try again after reprogramming the device.”

    could you give me some suggestion？

    thanks for any help

    Hi pnac:

    I have the same question at "aocl diagnose". I only can see Jungo intalled.How to got the "Accelerators group"for my arrira10.

    the path("D:\altera\15.1\hld\board")have no "a10_ref".How can I get it?

    you should download sof file to FPGA.

    and then reboot PC, you will see "a10_ref" under "Accelerators group"

    Hi, tiber, pnac, kevinjzw

    I know this post is a couple of months old, but I am having a similar problem on our side. Did you get the solution for this issue?

    In our case, I believe that the issue is with version id, it does not match. I greped this error and found the following in the file name acl_pcie_device.cpp

    // Kernel read command succeed, but got bad data. (version id doesn't match)

    ACL_PCIE_INFO("[%s] PCIe-to-fabric read test failed, read 0x%0x after %u attempts\n",

    m_name, version, iattempt);

    return -1;

    If you already have a solution for this please do let me know. Thanks.
