imx6q USB OTG does not work in device mode

xray — Wed, 06 Aug 2014 23:18:14 GMT

I have an IMX6 sabre SD board running Linux version 3.0.35.

The USB OTG port works find in host mode (when used with an OTG cable), but does not respond in device mode when the board is connected to a PC. lsusb on the PC shows no sign of the imx6 board.

I probed the D+ and D- lines on the board and neither is moves when the host cable is plugged in, so it is not responding properly as a device. A high speed device is suppose to drive D+ high and a low speed device is suppose to drive D- high.

Anybody have this working and know what's wrong?

Hi j b

most simple way to check usb device mode is to try connect to MFG Tool or

run SDK (it has usb device mode example)

IMX_6DQ_MFG_TOOL :

i.MX 6Series Platform SDK :

SABRESDP_IMX6_QSG

SABRE Platform for Smart Devices Based on the i.MX 6 Series - Quick Start Guide

In Freescale Linux BSP peripheral mode-supports MSC, and CDC (Communication Devices Class) drivers

which include ethernet and serial support.

However you should first load necessary driver (like g_file_storage) and perform

other actions (specific for each mode), to make i.MX6 work in device mode.

One can check L3.0.35_4.1.0_LINUX_DOCS

Best regards

The OTG port works in device mode with the the MFG_TOOL. It connects to the computer and the D+ line responds.

However, OTG in device mode is not working with my custom kernel.

Have I set something wrong in the configuration? I'm pasting my configuration file below.

Re: imx6q USB OTG does not work in device mode

Hi Hi j b

first, if board connects to MFG Tools then i.MX6 usb device mode

works well

then second - what are you trying to test now ?

regarding Linux - you can start with Demo images

L3.0.35_4.1.0_DEMO_IMAGE_BSP : i.MX 6Quad, i.MX 6Dual, i.MX 6DualLite, i.MX 6Solo and i.MX 6Sololite Linux Binary Demo Files.

Best regards

Re: imx6q USB OTG does not work in device mode

I'm booting the board from an SD card. On the SD card is my customized version of u-boot and the kernel. The board boots successfully and I can use the OTG port in host mode, but the board does not respond when I use the OTG port in device mode (ie connected to a computer). Since the OTG port worked in device mode with the MFG TOOL this suggests that I have configured something incorrectly in my kernel. I pasted my configuration file in the previous post. Have I somehow disabled OTG device mode?

Even all is good: board, linux configurations, all that will not work

until you do not understand how to test it: what one should do

and what results he should see.

For usb device mode links below may help

To use the gadget drivers you need to load them first. This is what I was missing and why my iMX6 board never worked in device mode.

The gadget functions are not complied directly into the kernel, but are modules stored here:

/lib/modules/3.0.35-.../kernel/drivers/usb/gadget

To get the iMX6 to act like an OTG device you must load a module before connecting to a USB host.

modprobe g_serial.ko

To unload the module

modprobe -r g_serial.ko

Alternatively you can change your kernel config file to load the module on startup.

This option requires you to load the module from the command line as shown above:

CONFIG_USB_G_SERIAL=m

If you change it

CONFIG_USB_G_SERIAL=y

Now the gadget serial driver is present in the kernel and does not need to be loaded from the command line.

modprobe g_serial

To unload the module

modprobe -r g_serial

It should be without '.ko'

Hi,

modprobe g_serial works for me but I tried to add CONFIG_USB_G_SERIAL=y to my config file (it didn't appear at all) and the port didn't recognized... there is something else i need to add to make it work on startup?

Thanks,

Tzipi
