Part Number: DP83822IF
Other Parts Discussed in Thread: AM6421
We designed a custom board utilizing the AM6421 System on Chip (SOC) for an industrial protocol. where we connected industrial ports (PRU-ICSS) using RGMII to DP83822IFRHBT. Using MDIO we are able to connect and configure PHY in internal Loopback mode (MII). This activity to test connection between SOC to PHY . Please find attached logs for same. Also we are able to probe TX CLK , TX CTRL , TX_DO to TX_D3. We can see signals. Can anyone help from team analyze logs & give us input? Notes - 1) we already confirmed hardware connection strapping option with SOR1 (0x467U) & SOR2 (0x468U) . Its matching. 2) Without Loppback we also tested Link status with Laptop. Its working. We are able to confirm Link status with LED indication & phy register. 3) Energy Efficient Ethernet (EEE) option is enable.
