The STM32F7 supports Ethernet with MAC (and DMA), according to doc en.DM00224583.pdf.I try to connect it to a KSZ9896 (ethernet switch) that provides a direct MAC interface in RMII.The KSZ provides configuration bits similar to the STM32 ETH_MACxxx.I...

I've a better answer !In the code generated by the cube, there is a ETH_HandleTypeDef heth;In the code, you need to set the adress of the PHY :heth.Init.PhyAddress = 0; // or 1, or...There is a default values for DP83848, for example, but you need t...

I just checked, we are "SWITCH_RX -> STM_RX".We struggle a bit to get it to work properly, and in fact the HAL driver is not really suitable for our case.Don't get me wrong, the HAL_ETH is perfectly fine for most cases, but it needs some tweaking to ...

No, I only modified the 2 parts for the LINKED_STATUS and the AUTONEGO_COMPLETE.There is also this : "you might need to "disable" HAL_ETH_(Read|Write)PHYRegister()."

Auto-answer, resolved !MAC-to-MAC is possible without PHY on a STM32F7.You need to customize the HAL to bypass the status bits that can block the startup.Usually it's code like this one : do { HAL_ETH_ReadPHYRegister(heth, PHY_BSR, &phyr...
