Hi Expert
Regarding to Figure 25.79 SGMII System Startup (Auto-Negotiation with PHY-LSI is not bypassed)
We are following this sequence but currently the step "wait ready interrupt" is not pass and the value of register ETNB1SGOPMS XMIT[1:0] is always equal to 00 (Idle state).
How can we change this state to Data communication state with this sequence.
Thanks, and best regard.
Hi,
We are checking this request internally. Kindly give us some time to come back to you.

if the sequence of auto-negotiation fails, then the attached SGMII linkpartner cannot support autonegotiation. Use the other flow instead, by-passing autonegotiation.Best Regards,Vasanth
Hi, I've already used the other flow, it's remained the same result. I've checked with the producer of the EthPhy.
They ask If I set the board in Auto-negotiation mode or Force mode.
However, I understand that there are no such modes in the board.
Do you have any idea?
Thanks, and best regards.
