Ethernet Over USB

[pratiknaphade2]

Hi,

Thanks in advance.

In our project we are using the iMXRT1172 processor, on which we have to use Ethernet over USB using CDC-RNDIS/CDC-ECM/CDC-NCM class.

Do we require external NIC (network interface card) to work with it?

Do you have any demo examples for the above?

Hello
Hope you are well.

We don't support any of those, but we do support RNDIS which also provides USB-to-Ethernet support. The main difference is that RNDIS is a Microsoft definition and the other ones are a USB-IF standard part of the CDC class. Looking at the code, it appears our developers used the CDC code to implement the RNDIS on top, so it wouldn't be too complicated for you to modify the code to support one of the other standards.

Best regards,
Omar
