USB CDC-ECM Support

w2vy — Tue, 06 Nov 2018 12:03:47 GMT

In the Device Stack Reference I see mention of CDC ACM and CDC RNDIS (and RNDIS is build upon ACM)

In the Host Stack Reference the CDC description seems to be more generic.

I need to support CDC-ECM on the USB Host of the RT1050, is the host side typically a thin layer between the USB and a virtual Ethernet Interface on the IP Stack?

I don't expect to be able to support RNDIS since my host does not support the Microsoft NDIS protocol.

While less important, CDC-ECM Device support would be nice to have too.

Hi Tom,

On the MCUXpresso SDK v2.4.0 for EVKB-MIMXRT1050, it is available an CDC Host example under “usb_examples->host_cdc_bm”. This example asks for a USB-UART Device, so, it will be required applying the proper changes to work with USB-Ethernet and with the desired functionality.

Hope this will be useful for you.
Best regards!
/Carlos
