Re: Did the zephyr project support EHCI/OHCI usb controller currently?


Joseph, Jithu
 

We presently have only USB device (and not USB host)  support in Zephyr, that’s why you are unable to find host controller drivers under Zephyr/drivers/usb

 

> if not supported hci really, why?

USB device side  was the logical place to start for resource constrained devices targeted by Zephyr.

(Going forward It is possible that USB Host / OTG functionality can get added based on community  interest / demand / contributions.)

Subject: [Zephyr-devel] Did the zephyr project support EHCI/OHCI usb controller currently?

 

Hi:

    i am doing the job of porting the zephy kernel to arm9  based socs, which embeded XHCI usb controller,    i reviewed the device drivers in ./zephyr/driver/usb  and did not found the EHCI moudle drver, even the "*HCI" symbol not found. so i want to know if i miss something?  if not supported hci really, why?

 

thanks for your kindly support.
