STM32F407 ETH Problem

[Xinda]

Hi Everyone,

I cannot choose the speed of the Eth. Pls see the pisture below. The version of the STM32CUBEMX that I downloaded is the latest.

Best regards,

Jason Pls see the picture.

Best regards,

If you mean 10 or 100 Mbit/s, this is not configured in the Cube. Your program will detect in runtime the result of link negotiation done by the PHY and set the speed accordingly.

Or, if you don't want auto-negotiation, program the PHY for desired speed (10 or 100) and set the ETH speed.
