66AK2G12: K2G USB device mode not working

Tom Chen
Prodigy 150 points

Part Number: 66AK2G12

Hi,

I have a application that needs to use both USB0 & USB1 as USB devices on our board. However, my PC still can not detect any USB device. I am wondering if usb-phy not working? or one or more kernel libraries not loaded? How do I debug?

[    0.254387] usbcore: registered new interface driver usbfs
[    0.254447] usbcore: registered new interface driver hub
[    0.254565] usbcore: registered new device driver usb
[    0.254803] usb_phy_generic usbphy:usb-phy@0: usbphy:usb-phy@0 supply vcc not found, using dummy regulator
[    0.254890] usb_phy_generic usbphy:usb-phy@0: Linked as a consumer to regulator.0
[    0.255112] usb_phy_generic usbphy:usb-phy@1: usbphy:usb-phy@1 supply vcc not found, using dummy regulator
[    0.255197] usb_phy_generic usbphy:usb-phy@1: Linked as a consumer to regulator.0

I update the device tree as following:

&keystone_usb0 {
    status = "okay";
};

&usb0_phy {
    status = "okay";
};

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

&keystone_usb1 {
    status = "okay";
};

&usb1_phy {
    status = "okay";
};

&usb1 {
    dr_mode = "peripheral";
    status = "okay";
};

I can see USB0_VBUS has 5v if an USB cable from PC connected to it.

    Hi Tom,

    Did you load any USB gadget driver?

    What kernel version do you use?

    Hi Bin,

    Linux 4.19.94-rt39-ga242ccf3f1. How do I load USB gadget driver? I manually loaded these two libraries, usb-core and phy-keystone:

    # modprobe usbcore
    [  355.229871] usbcore: registered new interface driver usbfs
    [  355.251906] usbcore: registered new interface driver hub
    [  355.267153] usbcore: registered new device driver usb
    # modprobe phy-keystone
    [  403.558398] usb_phy_generic usbphy:usb-phy@0: usbphy:usb-phy@0 supply vcc not found, using dummy regulator
    [  403.578456] usb_phy_generic usbphy:usb-phy@0: Linked as a consumer to regulator.0
    [  403.594156] usb_phy_generic usbphy:usb-phy@1: usbphy:usb-phy@1 supply vcc not found, using dummy regulator
    [  403.618558] usb_phy_generic usbphy:usb-phy@1: Linked as a consumer to regulator.0

    Tom,

    What do you see with command 'ls -l /sys/class/udc/'?

    Bin,

    Here is the response:

    # ls -l /sys/class/udc/
    ls: /sys/class/udc/: No such file or directory

    Tom,

    It means the USB module is not initialized properly for device mode. Actually you shouldn't need to manually load usb-core and phy-keystone. All these drivers should be loaded automatically.

    Either your board device tree doesn't configure USB correctly, or your kernel doesn't enable all necessary USB drivers. Attached below is the default kernel defconfig I copied from Processor SDK v6.3. Please use it as the default config and adjust according for your board, but don't modify anything USB related, and recompile the kernel. If everything is done correctly, you should see two entries under /sys/class/udc/ folder.

    Bin,

    After comparison, I found our USB config portion is exactly the same as that in your tisdk defconfig file. So, I double checked our device tree. The /keystone-k2g.dtsi file is not changed. I can see that we changed mmc, network portion etc per our board design, but the only change on USB is to change usb0 dr_mode from "host" to "peripheral". I would like to send you our dts file, however, it looks like the message log has no tool to send an attached file. Can you give me your email address? you can send me in a private message if you prefer.

    I am also wondering if your startup script has something important to USB?

    Hi Tom,

    This E2E does support attaching files. I will help you later on this.

    It does sound your kernel config and device tree shouldn't cause the issue. Can you please attach the USB portion of your board schematics, between the SoC to the USB connectors?

    Bin,

    Thanks.

    Attached is our dts file and

    Hi Tom,

    What is the output of command 'lsusb' and 'lsmod'?

    Tom,

    Please also attach file /proc/config.gz.

    Bin,

    Here is config.gz.6740.config.gz

    Bin,

    We found the 24MHz USB0 CLOCK signal is missing, ie, SOC_USB0_XO. I will let you know if the USB issue is fixed after the clock signal becomes available.

    Bin,

    The 24MHz clock signal is fixed, but the USB0 still doesn't work. Any idea? have you found anything suspicious in the config.gz?

    I created a new SD card and boot the system. Now, I do not see any "usb" text in dmesg. Probably, I manually load usb libraries like usbcore and phy-keystone in previous SD card.

    Hi Tom,

    I don't see anything standing out in your kernel config and dts, but all the needed kernel modules are not automatically loaded.

    What if you manually run command 'modprobe dwc3-keystone'? does it load all USB related kernel modules? You can check it with lsusb command. If so, does it create two entries in /sys/class/udc/ directory?

    Hi Bin,

    'modprobe dwc3-keystone' does not do anything. I do not see anything after running it in dmesg.

    There is no /sys/class/udc/ folder.

    In our custom board, we are using USB0 and USB1 as "peripheral" not "host" which is different from EVMK2G board, so I am wondering if our kernel config which is exactly same as EVMK2G needs any modification? do we need to enable USB device setting and disable USB host?

    I am also wondering if we need to match USB0 & USB1 settings in uboot device tree (ie, keystone-k2g-generic.dts) with the dt in linux device tree? Right now, we disable USB0 and USB1 in uboot device tree and enable them as "peripheral" in Linux dt, is this OK?

    No, kernel config doesn't need any modification. The difference between host and device modes are specified in kernel device tree, and the kernel usb driver will work accordingly at runtime. In theory, you could enable USB device and disable USB host in kernel config, but that has never been validated in the SDK, not sure if there is any bug in there.

    Yes that is okay. kernel USB operation is independent from U-Boot.

    I cannot think of anything else to check. The only option left is to debug the kernel driver to see why the init failed.

    You can start from the kdwc3_probe() function in drivers/usb/dwc3/dwc3-keystone.c.

    Ok, will do. By the way, will the usbconfigfs.sh help at this stage?

    See the script at:

    Bin,

    It seems that the kdwc3_probe() function in drivers/usb/dwc3/dwc3-keystone.c works fine.

    I added debug print at the entrance and before exit of kdwc3_probe() to confirm this function is called and print error code in case failure. However, this library is not called by default. I manually load and it is called twice, all finish with no error:
