Hi @sameer_imxrt ,

Thanks for your interest in NXP MIMXRT series!

MIMXRT1170-EVK has host CDC ACM demo and also has host RNDIS demo which is in SDKRoot\boards\evkmimxrt1170\lwip_examples\lwip_dhcp_usb\freertos. But we haven't ECM demo. BTW, this AN from the RT series may be helpful: https://www.nxp.com/docs/en/application-note/AN13940.pdf

Best regards,
Gavin

Hi, any demo code for USB CDC ACM for IMXRT1170?? Actually, we are already using the USB RNDIS for communicating with a linux device. But now, linux community removing support for same so we are searching for alternative. If you can suggest any alternative, then it is very helpful.

Hi @sameer_imxrt ,

The examples host_cdc in SDK support ACM but don't support ECM. The full SDK is available here:https://mcuxpresso.nxp.com/en/select

In addition, NXP provides a USB application note for RT series MCUs to enable customized classes: https://docs.nxp.com/bundle/AN14169/page/topics/introduction.html

Best regards,
Gavin
