TSE plus SGMII with Marvell 88e1111

Honored Contributor II

Hi all, 

I have built a system that uses the TSE core with SGMII option via PCS and PMA, which is connected to Marvel 88E1111 PHY. The board targeted is EP4SGX530KH40. The connection to the Board and the PC is proper and the data transmission is fine. This is done in Gbit mode. 


However when it is connected through LAN (100Mbps) connection, the system is not working. Can anyone help me in this regard?
