Hello,
I am currently using HAL library to interface my STM32F207 to a KSZ8863 switch using RMII Interface. The clock 25 Mhz provided externally which is then scaled to 50 Mhz to enable the interface. Now, I can read from the KSZ PHY register, i.e: I can read the CHIP ID and the default reset values but writing to the Ethernet PHY register is a complete failure.
Do I have to implement a bit bash mechanism as mentioned over here? Do I have to initialize both the PHY Ports?
Because I have tried that method and it is unsuccessful. I have pored through the datasheet to no avail. Does anyone have a solution or tips on how to proceed?Thanks and Regards.#ksz88632018-08-09 08:34 PM
