AM6548: USB Gadget Serial Issue

Tsai YunEn

Part Number: AM6548

Tool/software:

I'm trying to enable the USB serial gadget function. When I load g_serial, it shows as "ready," but when I connect it to a PC, I can never detect the device (COM port) in Device Manager.

Also, after I connect the Type-C cable, the Kernel still shows "Disconnected," even though the related Vbus is detected as HIGH.

root@am65xx-evm:~# modprobe g_serial
[  195.827441] g_serial gadget.0: Gadget Serial v2.4
[  195.827461] g_serial gadget.0: g_serial ready
root@am65xx-evm:~# ls /dev/ttyGS*
/dev/ttyGS0
root@am65xx-evm:~#

root@am65xx-evm:/sys/kernel/config/usb_gadget/g1# gpioget gpiochip0 5

1

root@am65xx-evm:/sys/kernel/config/usb_gadget/g1# cat /sys/kernel/debug/usb/4010000.usb/link_state

Disconnected

The relevant device tree settings are below. Can someone tell me how to fix this?

&wkup_pmx0{

usb5vsignal_pins_default: usb5vsignal_pins_default {
		pinctrl-single,pins = <
			AM65X_WKUP_IOPAD(0x00c4, PIN_INPUT, 7) /* (AD3) WKUP_GPIO0_5 */
		>;
	};

}

&usb0_phy {
	status = "okay";
};

//typeC interface
&usb0 {
	status = "okay";
	pinctrl-names = "default";
	//pinctrl-0 = <&usb0_pins_default>;
	pinctrl-0 = <&usb5vsignal_pins_default>;
	vbus-gpios = <&wkup_gpio0 5 GPIO_ACTIVE_HIGH>;
	dr_mode = "peripheral";
};

&dwc3_0 {
	status = "okay";
};

Hi YunEn,

Please attach the USB section of your board schematics, including all the connections from AM65x to the USB receptacle.

Hi Bin Liu ,

I have a circuit diagram for a USB Type-C interface, as shown in the image as USB0. Can you tell me how to solve the problem?

When you connect AM65x USB0 type-C port to a PC, do you measure the USB0_VBUS pin on AM65x to have 5v?

My analysis is that the state is "not attached," which means the host has not detected the device. However, gpioget gpiochip0 5 returns 1, which is the VBUS detect pin, indicating that the hardware actually detects the host's 5V. Therefore, I believe the problem is that although there is power on the hardware, the Device Tree Source (DTS) does not properly inform the dwc3 driver about the VBUS detect GPIO or the regulator. As a result, the controller is permanently stuck in the "not attached" state.

But I'm not sure how I should modify my Device Tree to fix this.

root@am65xx-evm:~# cat /sys/class/udc/4010000.usb/state 
not attached

root@am65xx-evm:~# gpioget gpiochip0 5 
1

To provide additional context, I have upgraded from Kernel 5.x to Kernel 6.1 (the latest TI SDK 09_03_05_02). On the hardware side, I tested using the old BSP version, and everything worked correctly.

However, when testing with the 6.1 DTS, issues appeared. Attached is the DTS file from the 5.x version.

Currently, the device tree configuration related to typeC (USB0), including Pinctrl and usb0_phy dwc3_0, is identical to the 5.1 DTS. I have verified that USB0_VBUS indeed has 5V, and using gpioget gpiochip0 5 returns 1.

However, the UDC status always shows:

> cat /sys/kernel/debug/usb/4010000.usb/link_state
Disconnected

> cat /sys/class/udc/status
not attached

I suspect that the issue may be with dwc3 or that the kernel is not correctly using the GPIO I configured (AD3 WKUP_GPIO0_5) as VBUS. Perhaps it is simply being treated as a regular GPIO, and therefore cannot drive USB correctly.

If there is a solution or if you need any additional information, please let me know. Thank you very much!

I did not get a chance to review the details. I will look into it tomorrow.

Hi Yun-En:

Have you read this linik for the USB section?

https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/latest/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory-K3.html

BR Rio

There are two instances of USB on AM62 SoC.

On the SK board, zeroth instance is brought out through a Type C port and the first instance is brought through a Type A port.

By default, USB0 port is configured to be in peripheral mode.

Since U-Boot does not support dynamic switching of USB roles,

below DT fragment needs to be applied and U-Boot image needs to be rebuilt to make USB0 port to be USB 2.0 host port.

Hi Rio ,

In the Linux stage, I'm unable to get usb0 to operate in peripheral mode and establish USB Serial Gadget communication using g_serial. My understanding is that the device trees used by U-Boot and the Linux kernel are not related.

After using modprobe g_serial to create /dev/ttyGS0, the PC is still unable to correctly detect a COM port.

The current usb0 device tree in my Linux DTS is as follows:

usb5vsignal_pins_default: usb5vsignal_pins_default {
		pinctrl-single,pins = <
			AM65X_WKUP_IOPAD(0x00c4, PIN_INPUT, 7) /* (AD3) WKUP_GPIO0_5 */
		>;
	};

&usb0_phy {
	status = "okay";
};

&usb0 {
	status = "okay";
	pinctrl-names = "default";
	pinctrl-0 = <&usb5vsignal_pins_default>;
	dr_mode = "peripheral";
};

&dwc3_0 {
	status = "okay";
};

Hi YunEn,

[ 2321.461199] udc 4010000.usb: soft-connect without a gadget driver

I don't think I never saw this message. Do you see it as well in kernel 5.x when USB0 works in device mode?

0 Tsai YunEn 11 months ago in reply to Bin Liu

Prodigy 90 points

I didn't see this message in version 5.1.

The message appears to indicate that the UDC cannot find a related gadget driver to define its functionality,

but I have already confirmed that the g_serial kernel config is enabled.

0 Bin Liu 11 months ago in reply to Tsai YunEn

TI__Guru**** 181026 points

Please compare /proc/config.gz in both kernel builds to see if there are any USB related configs are different.

0 Tsai YunEn 11 months ago in reply to Bin Liu

Prodigy 90 points

Below is my current Kernel Config. According to the documentation provided on the official website, the two should be consistent.

Compared to the previous kernel, the configuration is consistent, and both use only the g_serial driver.

It won't be easy for me to tell from this long list. You just need to compare it on both kernel. You also need to compare CDNS config options.

By the way, AM65x uses CDNS USB controller, not DWC3.

Based on the k3-am65-main.dtsi file, the dwc3_0 node uses snps,dwc3.

May I ask if my understanding is incorrect?

Additionally, I compared the Kernel Configs of both versions and found no significant differences. Both configurations are consistent with the settings in the official documentation:

Hi YunEn,

Sorry, this is my bad. For whatever reasons, I thought AM65x uses CDNS USB controller. But you are right, it uses DWC3 controller.

Do you see the same problem on AM65x EVM with the SDK9.3 prebuilt SD card WIC image?

0 Bin Liu 11 months ago in reply to Bin Liu

TI__Guru**** 181026 points

I just tested it on the EVM with SDK 9.3 prebuilt image (linked below), but I am unable to see the problem. Note the EVM by default has usb0 disabled, so the g_serial gadget driver is bond to usb1.

8345.config.gz

For your reference, attached above is the kernel .config for this kernel build.

0 Tsai YunEn 11 months ago in reply to Bin Liu

I will continue testing tomorrow. Additionally, I would like to ask if you can provide the device tree related to EVM USB1, or if I should just use USB0 for testing?

I ask because when I modified it to use USB0, it stopped working even though I used the same configuration and set it as a peripheral.

Thank you again for your help.

0 Bin Liu 11 months ago in reply to Tsai YunEn

TI__Guru**** 181026 points

The device tree is in the kernel: k3-am654-base-board.dts

0 Tsai YunEn 11 months ago in reply to Bin Liu

Prodigy 90 points

Understood. That should be consistent with my settings then. I'm currently using k3-am654-base-board.dts and modifying it, but for some reason, my USB0 isn't working correctly in peripheral mode.

I'll check the config.gz in detail tomorrow for any discrepancies. I'll let you know if I find anything. Thanks again!

0 Bin Liu 11 months ago in reply to Tsai YunEn

TI__Guru**** 181026 points

The EVM USB0 setting for USB2.0 is in device tree k3-am654-pcie-usb2.dtso file.

As shown in this dtso file, please ensure you configured serdes0 and serdes1 to PCIe, not to USB0.

0 Tsai YunEn 11 months ago in reply to Bin Liu

Prodigy 90 points

I have checked and disabled the relevant settings in k3-am654-base-board.dts as shown below. I am not certain if this is what you were referring to?

&serdes0 {
	status = "disabled";
};

&serdes1 {
	status = "disabled";
};

&pcie0_rc {
	status = "disabled";
};

&pcie0_ep {
	status = "disabled";
};

&pcie1_rc {
	status = "disabled";
};

&pcie1_ep {
	status = "disabled";
};

I compared the Kernel Config you provided with my current one. All USB-related settings are completely identical, but my USB0 still won't work in peripheral mode.

No. Not to disable serdes, but please set the serdes configurations in k3-am654-pcie-usb2.dtso.

vbus-gpios = <&wkup_gpio0 5 GPIO_ACTIVE_HIGH>;

What this gpio is doing to vbus?

0 Tsai YunEn 11 months ago in reply to Bin Liu

Prodigy 90 points

My apologies, but I'm not sure how I should modify this part. Would it be possible for you to provide an example for me?

My understanding is that I should rewrite the serdes node in k3-am654-base-board.dts. If I don't overlay it with a command, a .dtbo shouldn't take effect, correct?

0 Tsai YunEn 11 months ago in reply to Bin Liu

Prodigy 90 points

I have now removed the vbus gpio. I believe the vbus property should not be included in the node's configuration when it's in peripheral mode.

I have attached my current dts file for your reference. Thanks!

I'm able to use gpioget gpiochip0 5 to get the current 5V signal, and the state correctly changes from 0 to 1 when I plug in the USB cable. After using modprobe g_serial, the kernel logs appear to be normal. However, when I check the link_status, it consistently shows disconnected.

First of all, you should not need to manually control the VBUS (using a GPIO). The usb host provides VBUS 5v which should directly route to AM65x usb0 VBUS pin.

When you say GPIO turns on 5v on VBUS, did you check the voltage on usb0 VBUS pin next to AM65x? Then do you see usb0 DP pin goes high?

0 Tsai YunEn 11 months ago in reply to Bin Liu

Prodigy 90 points

I removed the manual Vbus reading part, and I also confirmed that the pin has gone high. I re-tested the old kernel, and it can indeed correctly enable the USB Serial function. I have meticulously compared the device tree and the kernel differences, and they are identical.

As previously discussed, I modified the device tree as follows:

&wkup_pmx0 {
	pinctrl-names = "default";
	pinctrl-0 = <&eepromdone_pins_default &iovolctrl_pins_default &vbusctrl_pins_default &mcuboot_pins_default>;
	..................
	usb5vsignal_pins_default: usb5vsignal_pins_default {
		pinctrl-single,pins = <
			AM65X_WKUP_IOPAD(0x00c4, PIN_INPUT, 7) /* (AD3) WKUP_GPIO0_5 */
		>;
	};
	..................
}


&dwc3_0 {
	status = "okay";
};

&usb0_phy {
	status = "okay";
};

&usb0 {
	status = "okay";
	dr_mode = "peripheral";
};

This still doesn't work. Furthermore, if I don't explicitly use usb5vsignal_pins_default, gpioget reads 0 even when the USB cable is plugged in.

I also have a question: if there's no need to configure pinctrl, how does usb0 dwc3 know which pin is the 5V input? And when does the handshake process start?

0 Tsai YunEn 10 months ago in reply to Tsai YunEn

Prodigy 90 points

I've confirmed that 5v-single-default is only used for software to make a judgment and is not relevant to this issue.

I've also confirmed that USB0-VBUS (AE7) is a dedicated pin for DM and DP, as shown in the previous schematic, and does not require special configuration.

I've verified that USB0-VBUS is HIGH, but the PC still cannot correctly detect a new COM Port.

At the same time, the state still shows "not attached" and link_state shows "Disconnected".

I cross-tested the previous image, and when connecting via USB Type-C, the DP line was pulled up. However, after switching to version 6.1, the DP pin shows no response.

I believe the issue is not hardware-related.
I measured VBUS and confirmed that there is indeed a 5V input, which is converted to 1V through the voltage divider circuit.
The device tree configuration for dwc3 usbphy and usb0 is consistent with the previous version (as mentioned in my earlier response).

Currently, I suspect the issue might be driver-related. Although the hardware measurement confirms that VBUS is present, the driver may not be detecting it, which prevents the subsequent process from being triggered.

0 Tsai YunEn 10 months ago in reply to Tsai YunEn

Prodigy 90 points

According to the specification for the USB_VBUS_ID_STAT Register, I used devmem2 to read the corresponding address. When the USB cable is inserted, the value is 0x07, and when it is removed, the value changes to 0x08.

root@am65xx-evm:~# devmem2 0x04000618 w
/dev/mem opened.
Memory mapped at address 0xffff9ff87000.
Read at address  0x04000618 (0xffff9ff87618): 0x00000007


root@am65xx-evm:~# devmem2 0x04000618 w
/dev/mem opened.
Memory mapped at address 0xffffaa1dd000.
Read at address  0x04000618 (0xffffaa1dd618): 0x00000008

This suggests that the usb_phy and VBUS detection are working correctly. The next step should be for the DWC3 controller to detect VBUS and start communicating with the PC host. I suspect the issue is that DWC3 is not properly receiving the VBUS signal, and therefore does not switch its state or trigger enumeration.

When I run cat on the link_state and state files, they show "not attached" and "Disconnected", respectively.

root@am65xx-evm:~# cat /sys/class/udc/4010000.usb/state
not attached
root@am65xx-evm:~# cat /sys/kernel/debug/usb/4010000.usb/link_state
Disconnected

However, I am not sure how the DWC3 driver actually retrieves the VBUS callback — is it by polling the register or through an interrupt?

Which function in the source code should I look at for this?

0 Bin Liu 10 months ago in reply to Tsai YunEn

TI__Guru**** 181026 points

Hi YunEn,

I have tested USB device mode on AM65x EVM with SDK 9.3 two weeks ago before my time off, and didn't see any problem. So I don't think your issue could be any problem in the USB drivers.

You have provided a lot of details in the last couple days, let me digest it along with catching up on my work after two weeks off, and will get back to you in a couple days.

0 Tsai YunEn 10 months ago in reply to Bin Liu

I have reorganized the items that have been verified so far as follows:

VBUS Detection
- Reading from address 0x04000618:
  - With cable inserted → 0x07
  - With cable removed → 0x08
- This confirms that VBUS input is correctly detected.
UDC Registration
- Running cat /sys/class/udc/ shows 4010000.usb, indicating that usb0 has been properly registered as a UDC.
Driver Binding
- Running cat /sys/class/udc/4010000.usb/function shows g_serial, which confirms that the g_serial driver is correctly bound.
UDC State
- Running cat /sys/class/udc/4010000.usb/state reports "not attached", meaning that the device is not enumerated by the host.
Link State
- Running cat /sys/kernel/debug/usb/4010000.usb/link_state shows "Disconnected", consistent with the UDC state.
DP Line Behavior
- When the USB-C cable is inserted, the DP pin is not being pulled up correctly, preventing the host from initiating enumeration.

Hi YunEn,

I checked SDK 9.3 on AM65x EVM and looked into multiple factors, but was unable to identify what could cause the problem.

Tsai YunEn said:
VBUS Detection

Reading from address 0x04000618:

With cable inserted → 0x07

With cable removed → 0x08

Do you see the same register values with kernel 5.x which doesn't have such enumeration problem?

Tsai YunEn said:

Where on the board did you probe the DP pin, close to AM65x or close to the type-C connector?

Please attach the full console boot log.

In Kernel 5.X, using devmem2 to read the same address, the value also changes between 0x07 and 0x08.
Both locations were measured, and in both cases the DP pin was not pulled up.

The complete Kernel logs for both 5.X and 6.1 are attached.

The kernel 5.x log doesn't have much of the boot messages. Please boot with kernel 5.x and run command 'dmesg' (without grep) and save it to a log file.

I don't see any issue in sw. I reviewed again your 6.1 kernel .config and device tree but don't see any thing obvious.

Do you measure 5V on the USB0_VBUS pin next to AM65x? I am not a hw guy, but with these resisters dividing the 5v of VBUS_C on the left side, is it still 5v on USB0_VBUS on the right side?

I have resolved this issue.

For some reason, usb0 seems to depend on the SERDES (PCIe). When the PCIe node is disabled in the device tree, no clock is provided to usb0. This also explains why you did not encounter any problems when testing with usb1, but I suspect that using usb0 would likely result in the same issue.

According to the CTRLMMR_SERDES0_CTRL register description, the default value is indeed 0x00 (USB3). However, we need to change it to 0x01 (PCIe0 Lane0) in order for it to work properly.

My assumption is that since SERDES relies on PCIe, we need to configure this register to PCIe mode so that SERDES can function correctly and provide the clock to USB3.

Hi YE:

Glad to know you resolved the issue.

Please note: on the AM64 DS told the below.

*************************

USB SuperSpeed and PCIe share a common SerDes PHY.

Therefore, USB will be limited to non-SuperSpeed modes when using the SerDes PHY for PCIe.
