Hi Linda,

We do not support OTG on our devices with USB.

If you want to see a reference schematic, please see the schematic in C2000Ware for the F2837x controlCARD. This will help you design the layout for the USB signals.

Regards,
sal

Hello Sal,

There is U16 in page 6 of F28379D controlCARD schematics as below:

Would you please kindly help whether this U16 is for automatically switching Host mode and Device mode like OTG or not?

If only Device mode is required, How should USB-ID be connected? Should it be left unconnected?

Thanks!

Best Regards,

Linda

We do not support OTG. Therefore, the ID is not necessary.
