Hello,

The Cortex-M Core are mainly intended for real-time application, delegating the high-speed communications (like ethernet and USB) to the Cortex-A cores.
With the above in account we do not provide an ethernet driver the Cortex M7.

Best regards,
Aldo.

Hi Aldo,

Thank you for the prompt reply.

Could we use the M4 - SDK_2.9 ENET example move to the M7 ?

Thanks.

Best Regards,

Wayne.

Hi,

I would not recommend it, but one can take the enet driver and start working from there (fsl_enet), but please note that this is not supported.

Best regards,
Aldo.

Hi Aldo,

Does the ethernet RGMII write in "fsl_enet" ?

If we want to modify some setting, Could we modify this file ?

Thanks.

Best Regards,

Wayne.
