How to use a OTG as a Host mode

ko-hey — Mon, 15 Feb 2016 05:54:46 GMT

Hi all,

I want to use OTG as a USB host I/F with i.MX6SL and have some question about it.

According to P9 of the EVK schematic, USB_TYPE_A connector (J10) is using as a Host mode.

Can I use EVK's driver without any customize when I use USB_OTG2 port as a Host mode ?

In my understanding, I need to set a ID pin to LOW when I use a OTG port as a Host mode.

However, EVK doesn't do anything.

Do I need any HW cutomeization when I use as a Host I/F ?

Hi Ko-hey

1. please try units tests (imx-test) (for example 045-Device-Host-Only-Test.txt):

.../test/mxc_usb_test/, read guidelines in /DOC folder

2. ID pin is absent in USB_TYPE_A connector, no need to set ID pin low

For description and usage ID pin please read usb2.0 specification on usb.org

Best regards

igor
