Does STM32MP15 ETH require input clock 25MHz and 125MHz only?

[Dat Tran]

I am using DP83848 PHY RMII interface and 50MHz external oscillator and PA1 as ETH_RMII_REF_CLCK pin. I ignored 125MHz input pin.

But when active ethernet, I see a problem similar to Stm32mp157 Ethernet problem, saying that there is no input clock.

I check my pin and 50MHZ clock on scope, it is fine. When I read datasheet, the clock has to be 25MHz or 125MHz? and has to connect to 125MHz input clock pin?

I see 50MHz should be fine.
