Ethernet 10Base-T1S on the STM32C5

[infoinfo982]

Hi,

On the stm32c5 nucleo board (NUCLEO-C5A3ZG) there is T1S OA PMD driver (not mounted?).  In the header file 

"stm32c593xx.h" exists a 10BASE-T1S control register "MAC10BT1SCR". 

But there is no documentation in the Reference Manual RM0522 Rev 1, and I can't find a way to enable T1S on MXcube2.

Can anyone help me here? Is the T1S PDM really integrated in the C5 series?

I would really like to experiment with 10Base T1S.

Regards

Patrick

Hello,

Since there is no indication in the documentation the product supports the T1S, it doesn't support it. I will escalate it internally to double check. Internal ticket for follow-up CDM0061715 (not accessible by the community users).

For the T1S PHY footprint on the board it may be used for another product.

Quick googling shows that 10BASE-T1S specifies only the PHY. So the MAC of STM32C5 should work with any compatible PHY. Why does it have the 10BASE-T1S control register "MAC10BT1SCR" ?

DS15137 has no notion of 10BASE-T1S in ETH section.

Please show that section of that file.

Issue internally confirmed. No T1S support on STM32C5.

All T1S mentions will be removed from the STM32C5 package.

Thank you for your contribution.
