Hi,NXP
I am testing 10BASE-T1S using the S32K5 and TJA1410. Currently, I can see waveforms on the TX pin, and there are also waveforms on the RX and ED pins, which indicates that signals can be received on the MDI. However, the TX pin is unable to send data to the MDI.
Best Reagrds.

Hello @wuxianlong ,
How have you measured the MDI? MDI is differential interface so you need to use differential oscilloscope probe. MDI requires proper differential termination - please refer to AN14787 - Application note 10BASE-T1S Ethernet PMD transceiver TJA1410, Rev. 1.0 , chapter 3.3.
Best regards,
Pavel
