Dear team,

 

I would like to ask about USB connection of i.MX6DQ.

My customer wants to connect external USB HUB chip (Microchip’s USB4604) to USB OTG Controller of i.MX6DQ via UTMI PHY1.

(1)

Is it OK?

If any consideration is needed, please let me know.

(2)

The customer wants to control UTMI PHY.

Is it possible to control it from API level of OS (as a general story)?

 

Best Regards,

Miyamoto
