Hi.
in odl sdk musb-am335x.c is exist,but in sdk 9.x not have ???
Its equivalent file in SDK9.x kernel is musb_dsps.c.
if I want to use usb host, what should I do ??
You would need to set dr_mode to "host" in the usb node in your board kernel devicetree file.
Please run the following script on your board and provide its output.
