Other Parts Discussed in Thread: DP83TC811, DP83TC811SEVM
Dear TI
We purchased a DP83TC811EVM board, and test the connection, but failed. The details as below:
Connection:
DP83TC811EVM(master mode) -> 100BaseT1 to 100BaseTx Converter(slave mode) -> PC
Connection:
DP83TC811EVM(master mode) -> 100BaseT1 to 100BaseTx Converter(slave mode) -> PC
Config:
The resistors of strap are all empty, but we config "xMII Control Register" to 0x4241 via MDIO port.

Problem:
When we start ping command on PC, we can find the LED1 on EVM board are flashing, and "RX FIFO Overflow Status" becomes 1.
When we stop ping command on PC, the LED1 always on, and "RX FIFO Overflow Status" becomes 0.
That's mean the DP83TC811EVM received the ping package from PC.
But, when we measure the signal of RGMII port,
RXD0: Low level
RXD1: Low level
RXD2: High level
RXD3: High level
RCLK: 25MHz
RXDV: Low level
Why the received data can't output from RGMII RXD port? If any other register we need config?
