STM32N645Z0 Ethernet Configuration Support in STM32CubeMX

[modecs]

I am currently evaluating the

for use with 1000Base-T Ethernet and am attempting to configure the peripherals using STM32CubeMX. While following the same process as with other STM32 chips, I was unable to find the Ethernet configuration under Pinout & Configuration -> Connectivity. Could you kindly advise where I should configure the Ethernet settings?

Thank you for your assistance.

Hello @modecs 

Thank you for your contribution.

ETH should be available for STM32N645Z0, according to*DS14791 Rev. 9, Table 18, which indicates Ethernet signal support for the VFBGA142 package. In particular, for MII mode the following signals are listed as supported in VFBGA142:

ETH1_MDC on B12, ETH1_MDIO on K1, ETH1_CLK on K3, ETH1_MII_RXD0 on L2, ETH1_MII_RXD1 on M1, ETH1_MII_RXD2 on N1, ETH1_MII_TXD0 on P1, ETH1_MII_TXD1 on N3, ETH1_MII_TX_EN on N2, and ETH1_MII_RX_DV on K2

For RMII mode, the supported signals are

ETH1_MDC on B12, ETH1_MDIO on K1, ETH1_CLK on K3, ETH1_RMII_REF_CLK on M2, ETH1_RMII_CRS_DV on K2, ETH1_RMII_TX_EN on N2, ETH1_RMII_TXD0 on P1, ETH1_RMII_TXD1 on N3, ETH1_RMII_RXD0 on L2, and ETH1_RMII_RXD1 on M1.

A ticket #0062266  has been escalated to the development team to investigate and correct this behavior.

I will keep you posted with updates.
