- Implementing SGMII Interfaces on the PowerQUICC™ III - NXP Community
Figure 3 illustrates SGMII configuration and auto-negotiation Auto-negotiation is controlled and monitored via the PQIII ten-bit interface (TBI) and the TBI MII set of registers Figure 3 SGMII Link Exchange SGMII is the mode of communication between the MAC and PHY that allows for copper 10 100 1000BASE-T (IEEE 802 3ab) operation The speed
- t2081 SGMII ethernet is not working in uboot - NXP Community
When reading the SGMII PHY Identifier Lower register (MDIO_SGMII_PHY_ID_L - 0x3), I am receiving 0xffff Is this a valid value, or does it indicate an issue with the PHY communication? **Question 2:** When reading the SGMII status register (MDIO_SGMII_SR), the LINK_STAT bit is always 0, indicating an invalid link What could be causing this issue?
- Can SGMII (2. 5G) be connected to 2500Base-X? - NXP Community
To sum it up: 2500Base-X follows the 10G rules and disallows short preambles 2 5G SGMII is a "fast SGMII", thus follows the 1G rules and allows for short preambles The Solution to the Preamble Problem The Aquantia AQR109 PHY "fixes" the problem somehow The MAC still sends short preambles (in 2 5G SGMII mode), but things work fine with the

- Mac to Mac communication over SGMII - NXP Community
We are using 2 T4240 SoC based custom boards We are trying to connect the 2 macs over sgmii connection We connected SGMII pins TX of one MAC to RX of other mac and visa versa And we configured both macs as fixed-link as below, no mdio configuration fm1mac2: ethernet@e2000 { phy-connection-type = "sgmii"; fixed-link = <2 1 1000 0 0>; };

You could use mdio read command to check the status of a SGMII link => mdio list FSL_MDIO0: 4 - AR8031 AR8033 <--> DPMAC17@sgmii FSL_MDIO1: => mdio read DPMAC17@sgmii 1 Reading from bus FSL_MDIO0 PHY at address 4: 1 - 0x7969 => The link partner link status bit is in Register #1 on the PHY The 'Link Status' bit is bit #2 (from the left) of the
- LS1046A - SGMII Interface - NXP Community
Please refer to SGMII_IF_MODE(SGMII IF Mode Register) in LS1046 Reference Manual, it contains control bits to set the interface mode SGMII_IF_MODE[SGMII_EN] SGMII Mode Enable When set to '0' (Reset Value), the PCS operates in standard 1000Base-X Gigabit mode, when set to '1', the PCS operates in SGMII Mode
- SJA1110 SGMII MAC to MAC - NXP Community
Hello, is this MAC to MAC connection only possible on the SGMII ports? We are trying to connect port 2 of the SJA1110 to an MCU over RMII (without a PHY) on the same PCB We hooked up a REF_CLK at 25Mhz and setup the M
