Issue to configure PFE0 controller and use 100BaseT1 automotive ethernet

[winstonlewis]

Hello,

I'm using S32G3 RDB3 board, Electrobit Tresos version 29.2.0, Goldvip version 1.11.0 and I'm facing issue to configure PFE0 and use 100BaseT1 automotive ethernet. I'm not able to see ethernet frames over automotive ethernet channel. 

Also is it possible to use PFE0 & PFE2 in parallel as both of these controllers are connected to same GPIO pins.

Kindly help me with this issue.

Thanks

Hi,

For the available information, we understand that the 100BASE-T1 channels are connected to the SJA1110 PHY under RDB3, can you confirm that the SJA1110 was configured correctly?

As for the configurations, can you help us share the relevant configurations for PFE0? Which pins are you using?

As for the following inquiry:

Also is it possible to use PFE0 & PFE2 in parallel as both of these controllers are connected to same GPIO pins.

We might be misunderstanding, but you cannot use the same pins for both controllers. You can use other pins to enable both controllers, similar to the following community thread:
