stm32h723zg Clause 45 MDIO

heisenbug · ‎2024-03-27

Hi all,

i see H7 supports clause 45 MDIO access, but in the HAL library looks not implemented, i see only clause 22.

How should i proceed to read/write c45 ?

Thanks,

angelo

Hello,

Which MDIO interface you are talking about? is it the MDIO of the ETH or the MDIO slave (MDIOS)?

MDIO inside the ETH IP

Well, found now that the PHY chip i am using is supporting C22 to C45 bridge (multiple devices addressing), so don't need to add Clause 45 to HAL. Anyway, since h7 supports Clause 45, would be nice to have it imnplemented in HAL.
