The fact that you use constant 0 in the source code to set a pointer to null-pointer value is nothing more than just a piece of syntactic sugar. But not every transceiver supports this feature, when RTL8211 shares one MDIO bus with other transceivers which doesn't support this feature, like mt7530 switch chip (integrated in mt7621 SoC), it usually causes address conflict, leads to [ 1. Dislike. To mention one more, when I pull the reset pin of the LAN8742 to low, the 2. 9 = 0 restart A/N (0100:0000) 0. Note also that on some (older) Xilinx ML4xx boards, PHY address 0 does not properly respond to this query It is important to keep in mind that on a shared MDIO interface (such as the one demonstrated below), the PHYs should avoid using the MDIO broadcast address (PHY address 0) for proper operation: ps7_ethernet_0: ps7-ethernet@e000b000 { Ethernet PHY address. Here is my full serial output:-----lwIP TCP echo server -----TCP packets sent to port 6001 will be echoed back; WARNING: Not a Marvell or TI Ethernet PHY. 255.

I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there. As you may imagine this First version of the project with only MIO-ethernet (ethernet0) works well with the next configuration in system-conf. But some MDIO device like mt7530 switch chip (integrated in mt7621 SoC), also use address 0 to configure a specific port, when use mt7530 and rtl8211f together, it usually causes address conflict, leads to the port of RTL8211FS stops working. Having said that, address 0 usally happens to work if there's only one PHY on that bus, since it will be the only one responding to that broadcast. 赞 How to Access PHY Register Application Note Version1. The Turn Around allows the PHY to take over PHY-LSI Address: Specify a value between 0 and 31.
