S32G2 can2net modified to pfe_mac2

[youke]

Hi, NXP

I am currently testing the can2net functionality using the s32g2rdb hardware. I have implemented can2net by referring to AN13423, with net using pfe_mac1, and can obtain net messages from the hardware P3A interface.
Since we need to achieve simultaneous startup of the A+M cores, the A core uses gmac0, which conflicts with pfe_mac1 used in can2net. We are now considering switching to pfe_mac2 for transmission. I have modified the EB as follows. After the modification, corresponding data has been input to CAN, but no network data is being transmitted from P3B. Please assist in troubleshooting;

Change all can2net instances to pfe_mac2

Looking forward to your response.

Hi,youke

Thank you for contacting us.

Which version of LLCE are you using? Do you plan use the pfe SGMII mode?

Hi，joey

I have solved the above problem by modifying the code and reading the data from pfe2.
Here are some new questions:
1. rdb2 pfe_mac2 is connected to ksz9031 externally. If we connect 88q2112 automotive Ethernet conversion externally to pfe_mac2 on our own board, what modifications are needed to the M-core driver in the current can2net project?
2. If the A core acts as the pfe master, can the M core still transmit CAN data via can2net from pfe_mac0 and pfe_mac2 after starting as the pfe slave?
Thank，

hi，youke

Thank you for your reply.

I think you can focus on this structure.

Also, do you want eth2eth functionality? Refer to manual, LLCE only supports for can2can/can2eth/eth2can in demo project. May modify the FDK package to support more function, but it need more purchase.

Hi，joey

We do not use net2net.
Thank you for your guidance. I think this may resolve my first question.
I would like to add a second question. After the A core uses the pfe master driver pfe_mac0 (sja1110) and pfe_mac2 (88q2112 phy), can the M core be used as a slave mode to use pfe_mac0 and pfe_mac2 for can2net output?

hi，youke

Thank you for your reply.

You can refer to the CAN Gateway demo in goldvip for the multicore LLCE.  CAN frames are transmitted from M core to A core via CAN2ETH.

Hope it can help you.
