We are using C6657 with SGMII. May not be the case where the link can be established during the implementation of the auto-negotiation with the following differences:
156.25MHz×8(MPY)×1(harf rate) ---- NG
156.25MHz×16(MPY)×1/2(quarter rate) --- OK
By the difference in setting the PLL, I want to know what the cause of this difference.
MDIO link is established. Link SGMII is is not possible.
Thanks
