Can't use USB device CDC VCOM on MIMXRT685SFAWBR

Hi everyone,

I'm currently having trouble connecting the USB device to the computer when using the VCOM CDC USB device example from the SDK. Does anyone have any tips for configuring USB on the MIMXRT685SFAWBR? I've attached the schematic and USB example from the SDK I'm using.

Thank you for reading my post,

Duong

Hello @yang_lee ,

Did you evaluate CDC VCOM demo on RT685EVK ? Did it work ? Please kindly clarify.

Have a great day,
Kan
