Memory Mapped IO (PortIO) - Code 12 RRS feed

  • Question

  • I am going the use Port IO driver to access Memory Mapped GPIO. When I modify the INF file accordingly as specified in following link

    http://support2.microsoft.com/default.aspx?scid=kb;en-us;Q323595

    But I cannot install the driver on Windows 7. I am getting Code 12 error code. When I check the device managet ( Resource by Connection view ) there is no any conflict relevant to Physical address I am going to access. What could be the reason for this issue ?

    Regards...
