STM32 USB OTG Dual Role

[Shikamaru]

HI team,

          I am using STM32F7 series controller. I want to use USB OTG in dual mode where I want to run USB device and Host on same application. So till now I couldn't find a single application or sample related to this. Can anyone narrow down the path for me how to achieve this. 

regards,

Shikamaru

FBL, Tuxera haven't replied to my email, not even an automated reply!

Maybe ST need to put more effort into choosing their partners.

I see why the Raspberry PI industrial platform is growing so fast.

Hello, I'm running through the Dual-role TCPP installation for the H743, and am curious as to why TCPP, that's not strictly needed for dual-role USB is it?

We would like to have two USB ports on our board, one for a PC link, the other to connect in host mode to keyboards and other devices.  We current have the hardware designed in so we can switch the USB-C from Device to Host, and that is working well.
Is the USB PB application you referenced going to show us how to set up the two USB for simultaneous device and host operation on the H743?

It should be possible on the H743 because it has dual Synopsis USB controllers, so one can operate as a device, and the other as a host using two USB connectors.
