hello~everyone
I designed my custom board that refer to MS_TI_DM814x_BB_REVD in MISTRAL. And I changed PHY chip (88e1111).
and I can cotrol PHY register over MDIO. So I setted GMII 1000 Mbps mode and I transmitted a data to PHY chip from MAC in the custom board.
In case of internal loopback test in PHY, the transmitted data is verified. But external 1000Mbps loopback stub test( I connected 1-3, 2-6, 4-7, 5-8) wasn't verified. so I checked the MDI[x] pin ...the pin doesn't work...always LOW.
I think the reason is that TX_ER pin in PHY is NC in my custom board.
Is it right? anyone help me...
p.s H/W configuration
CONFIG 0 => LED_TX
CONFIG 1 => LED_LINK1000
CONFIG 2 => LED_VDDO
CONFIG 3 => LED_DUPLEX
CONFIG 4 => LED_LINK1000
CONFIG 5 => LED_LINK10
CONFIG 6 => LED_VSS
But I setted the HWCFG_MODE[3:0]=1111 over the resigster 27_3:0 manuallly
