Hi,

what am I doing wrong, if I see 100MHz on COP instead of 625MHz?

Thanks

Hi Christian,

It looks like you are trying to implement SGMII 6 wire interface. For this, please check if the following bits are configured correctly.
Register 0x10 bit 11 = 1 (SGMII Enable)
Register 0xD3 bit 14 = 1 (SGMII 6-wire enable)
Register 0x14 bit 7 = 1 (SGMII Auto-neg enable)
