GMAC0 Clock not working on s32g2 kernel - Linux BSP-43

Hi All,

We are trying to resolve an issue with Linux BSP-43 that in our custom board we have gmac0 interfaced with a PHY in MII mode.

The detail of the issue is mentioned in the below ticket. The NXP representative looking into this ticket is on vacation, can someone help to resolve it. We have already spent a lot of time kind take this in priority.

Hello @khan_misbah,

What I understand is that you need to configure GMAC in MII mode. Since the BSP is meant for the RDB2 board and it does not have an MII Ethernet PHY, there is no straight forward procedure to configure MII. I will need to contact the internal team for this request, however, please note that most of them are not present due to national holidays. I apologize for the time it will take for us to get feedback from them.

I will get back to you as soon as possible.

Thanks in advance for your patience
