[U-Boot] MPC8548: U-boot "Got error 4" while receiving packets

Hi,

We are using u-boot for our custom board having MPC8548. Board is able to come up properly. MPC connected to DSP via (MPC : RGMII)-SGMII-SGMII-(RGMII : DSP). We are able to send packets from MPC to DSP successfully, but when DSP intern sends back to MPC we are getting below error on u-boot console. Got error 4 Got error 4.

I came to know, "Got error 4" is a CRC error indication in the status bits of the receive buffer descriptor (tsec.h).

What might be the problem, Why is it happening so?? Is there a way to get break through. Please help us in regard at the earliest.

Thanks & Regards Ajeesh Kumar
