C6678 PCIe problem

Hi,

   The question I early posted here：https://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/500671

    The value of PCIE_SERDES_STS is 0x201,so the issue is "loss of signal on lane1",The SW I set in C6678 as following:

    SW6[4:1]=0000,SW5[4:1]=0000,SW4[4:1]=0000,SW3[4:1]=0001

    How can I solve the problem?

    Best wishes,

    Simon
