    ScottB
    Chris, There are two of these 22.579MHz crystals to support 2 different footprints. Y7 is a through hole type that is not populated in the design (noted on schematics as "DNI"). AUXOSC is not required for most designs. AUXOSC is needed when a specific frequency is required for the design...

    I am using a TI EVM8148 development board to connect to an external PCIe device (Xilinx ML605 board) and have been having some problems. I figured out that the current EZSDK for the DM8148 does not include PCIe since it includes PSP version 04.01.00.05 . I also found that the latest PSP 04.01.00.06...
