MII on STM32H730VBTx

[Aasdf.3]

STM32CubeMX doesn't show MII as an option for Ethernet on the STM32H730VBTx. Is MII not available on this part (RMII only?) or is there a problem with STM32CubeMX? The datasheet suggests it should support MII.

Hello @Community member​ 

Thanks for your question,

Yes, the MII is supported on STM32H730xB but not on all Package, in fact, the H740VBTx has the LQFP100 package and the signals needed to reach the MII mode are not all available on it.

Here, I'm talking about the ETH_MII_TX_CLK signal which is not supported on LQFP100 and therfore the MII is not supported.
