    Hi,
    I want to use McBSP1 for transmission and reception of data.CLKX1 is provided as external(2.304MHZ) and FSX1 is configured to generate on every DXR to XSR copy. FSR1 is configured to be generated as external.
    CLKX1 is provided as the source for sample rate generator and CKR1 generated by sample rate generator.
    But, McBSP1 is not working at all, even though McBSP0 worked properly with the same configuration.
    The difference which i found out for McBSP0 and McBSP1 are in the layout of base board. All the pins of McBSP0 are connected from J30 to J2 connectors. But, in the case of McBSP1, FSX1 and FSR1 pins are connected from pins 83 & 13 of J30 connector to U6 chip (pins -6 & 9) , which in turn is routed to J2 connector.I was just wondering whether i should do some extra step to turn off U6 , so that McBSP1 works correctly. Please revert on this as soon as possible.

    Thanks & Regards,
    Padmakumar
