RNDIS or NCM with ESP32-S2 (Tinyusb)

Postby kino0924 » Mon Aug 22, 2022 9:55 pm

Hi,

I am trying to implement Ethernet over USB so I can control my board with TCP/IP
I am going to connect from Windows machine so I thought RNDIS or NCM will be suitable.

I followed lots of Tinyusb example as well as ESP-IDF's implementation.

So, I created following code for to create USB Ethernet first but Windows is saying that its "This device cannot start. (Code 10)"
I also did pretty same implementation for ECM, just changing define and configuration_descriptor but no good

I am using VSCode + ESP-IDF v5.0-beta1

Can someone tell me what am I doing wrong?


Thank you.
