Part Number: TDA2PXEVM
Other Parts Discussed in Thread: PMP

Tool/software: Linux

Now i change the board , remove the vbus and id of usb1,i want use the usb1 as a mass storage device.

In software i make some modification as follows:

(1).dra7-evm-common.dtsi

-&omap_dwc3_1 {

- extcon = <&extcon_usb1>;

-};

&usb1 {

- dr_mode = "otg";

+ dr_mode = "peripheral";

};

(2) then insmod some ko:

insmod configfs.ko

insmod libcomposite.ko

insmod usb_f_mass_storage.ko

insmod g_mass_storage.ko file=/dev/mmcblk0p1 stall=0 removable=1

have print info :

[ 482.681589] Mass Storage Function, version: 2009/09/11

[ 482.688258] LUN: removable file: (no medium)

[ 482.692718] LUN: removable file: /dev/mmcblk0p1

[ 482.710377] g_mass_storage gadget: userspace failed to provide iSerialNumber

[ 482.718269] g_mass_storage gadget: g_mass_storage ready

My question is that when i insert usb into pc, pc does't detect a device,both D+ and D- are not pullup .

Can you tell the version of the TI Linux SDK release you are using?
Also can you provide the complete kernel log for analysis (dmesg) ?

Thanks.

The log looks OK, We don't see anything wrong in it. Thanks for sharing it.

I see from you have commented the extcon in the dts file, so can you tell the USB receptacle used on your board? Note that ID pin can be omitted since you are explicitly setting the driver to operate in device mode, but note that the receptacle used must of type-B standard/micro. Otherwise, we need to make sure that the id-pin is floating.

Can you run below and provide the info:

cat /sys/kernel/debug/48890000.usb/mode

lsmod

Thanks.

Now, the USB receptacle we used is type A,but ithink it`s not matter，because we just use three lines (DM DP GND)，

and i can use the usb of my board as the device to boot (tda2p have a usb boot mode).

Looked at lsmod and mode status provided and it looks fine.

We checked to reproduce this on the TI-EVM with the same updates to dts file (removing extcon entry and setting the dr_mode to peripheral) and found the same behavior as yours. Introducing back the extcon entry to the dts file make the gadget to be detected by the host PC properly.

So the answer to your issue is that you would need the extcon entry for the DWC3 driver to have the gadget (device mode) to work correctly.

The reason for this is that the linux dwc3 controller driver is configured to be in DRD mode.

Check the .config file in your kernel directory and you would notice that below"

# CONFIG_USB_DWC3_HOST is not set

# CONFIG_USB_DWC3_GADGET is not set

CONFIG_USB_DWC3_DUAL_ROLE=y

For more understanding of this, Suggest you to look at the drivers/usb/dwc3/core.c file and look for the code flow dwc3_probe() -> dwc3_core_init_mode() -> and dwc3_drd_init() ..

Thanks.

I look at the driver about dwc3 before. linux dwc3 controller driver depends on the "dr_mode" configed in dts to select mode.the code as fellow:

static int dwc3_core_init_mode(struct dwc3 *dwc)
{
	struct device *dev = dwc->dev;
	int ret;

	switch (dwc->dr_mode) {
	case USB_DR_MODE_PERIPHERAL:
		dwc3_set_mode(dwc, DWC3_GCTL_PRTCAP_DEVICE);
		ret = dwc3_gadget_init(dwc);
		if (ret) {
			dev_err(dev, "failed to initialize gadget\n");
			return ret;
		}
		break;
	case USB_DR_MODE_HOST:
		dwc3_set_mode(dwc, DWC3_GCTL_PRTCAP_HOST);
		ret = dwc3_host_init(dwc);
		if (ret) {
			dev_err(dev, "failed to initialize host\n");
			return ret;
		}
		break;
	case USB_DR_MODE_OTG:
		ret = dwc3_drd_init(dwc);
		if (ret) {
			dev_err(dev, "limiting to peripheral only\n");
			dwc->dr_mode = USB_DR_MODE_PERIPHERAL;
			dwc3_set_mode(dwc, DWC3_GCTL_PRTCAP_DEVICE);
			goto gadget_init;
		}

So it is no matter if CONFIG_USB_DWC3_DUAL_ROL was configed or CONFIG_USB_DWC3_GADGET was configed.

CONFIG_USB_DWC3_DUAL_ROL just have influence on build files.

the code flow will is dwc3_probe() -> dwc3_core_init_mode() -> and dwc3_gadget_init() ..

Another questions i don`t understand is when i add extcon entry in dts,i can`t find the usb1(48890000.usb) device in /sys/bus/platform/devices/.

And i can`t find the definition of usb1 registers on tda2px TRM，can you tell me where the definition of usb1 registers

Thanks

hi， do you find something？

Hello,

As mentioned in my previous post, we could reproduce this issue on our TI EVM if I remove the extcon entry and set the dr_mode="peripheral". But, we get it back to work correctly if we put back the extcon entry in the dts file. So there is a dependency on the extcon which is doing something failing in your case.

Suggest you to explore the code and see what is the this dependency that can be removed. This would solve the problem.

Thanks.

Hello,

Now i resolve the problem. It indeed need to add the extcon. because when you load the dwc3-omap.ko,it will register a extcon and set UTMI_OTG_CTRL according to you detection by extcon. but we need make some changes.
