Using KSZ8863 3Port Ethernet Switch on STM32f207VET
Hello.
I'm going to use STM32f207VET and KSZ8863 (3Port Ethernet switch) for custom boards in this project I'm working on.
The switch and stm32 are already hardware-connected to the RMII interface on the custom board.
Clock used an external crystal and set it at 50 Mhz as below.
What I want to set up on these devices is as follows.
100Mbps Speed, Full Duplex, Auto Negotiation.
I think you can select user PHY among the external PHY configuration options in the tube and then modify the code inside the HAL_ETH_Init() function after making other settings according to the KSZ8863 data sheet.
As far as I know, to drive the Ethernet switch, you need to enter the values in each of the two PHY registers according to the MDIO protocol.
But I don't know if what I know is right.
If what I know is correct, do I just need to set the PHY register using MDIO?
If what I know is wrong, please let me know which one is wrong.
Also, please let me know how PHY will be initialized.
Thank you.
