Linux/AM3358: USB debugging

Bill Morgan
Expert 1550 points
Part Number: AM3358


Tool/software: Linux

I have a new custom board with the AM3358 and I need to test USB.

When I add a USB device to the bus, I do not see it show up in Linux.

I would like to check for bus activity.

Is there a way to generate USB bus activity so we can check for it on the scope from either Linux or U-Boot?

So far, I have been running this ‘usb start’ command from uboot, over and over and not seeing any activity on USB0_DP N17 or USB0_DM N18.

=> usb start
starting USB...
USB0:   Port not available.
=>

if there is a Linux command to test usb and generate bus activity, please let me know.

Thanks.

    Bill,

    U-Boot is not an ideal please to test/debug usb, Linux kernel is a better environment.

    It sounds like you need the AM335x usb module to work in host mode. You don't need any specific Linux command to generate usb bus activity in Linux. Once the Linux boots up and the the usb bus is ready, attaching any usb device should automatically trigger usb enumeration and you should be able to see bus activities during the numeration.

    We recently published a series of training videos for usb system design, please check the following link and hope it helps.

    will the linux 'lsusb' command trigger any activity on the bus?

    here is the output I'm seeing:

    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

    I never checked on this, but I don't think so. 'lsusb' command only prints the information the kernel collected during device enumeration.

    It tells you have one usb bus ready, but it doesn't mean the whole usb design (including both hw and kernel configuration) has no issue.

    Which kernel version do you use?

    Please attach the full kernel boot log.

    Thanks for the kernel log, it shows your board uses USB0 in host mode. Please run the following command on your board to get a register dump, which tells the usb controller status.

    # grep -i 'devctl\|power' /sys/kernel/debug/musb-hdrc.0/regdump

    Thanks for the kernel log, it shows your board uses USB0 in host mode. Please run the following command on your board to get a register dump, which tells the usb controller status.

    # grep -i 'devctl\|power' /sys/kernel/debug/musb-hdrc.0/regdump

    # grep -i 'devctl\|power' /sys/kernel/debug/musb-hdrc.0/regdump
    Power : e0
    DevCtl : 19

    The register dump shows the usb controller and the bus are ready.
    When you attach any usb device to the usb port, the linux console doesn't print any enumeration message? If so, please attach your board schematic.

    No messages are printed when the usb device is attached to the port.

    I am unable to post the schematic here, but can post it to your secure site. I will email Brad Griffis about this.

    Sounds good. While me waiting for the schematic, can you please check if the 5V vbus presents on the usb receptacle?
    And you changed usb0 dr_mode to "host" in your board dts file, right?

    I am not sure what causes the crash, but it is minor, I already got all I need on the Linux side.

    I received the schematic, thanks, but it seems not complete, the usb0 DP/DM signals go to a connector then missed on the other side.
    I have forward the schematic to our usb hw expert for review, he might reply here if he has any comments.

    I don't see anything wrong with schematic portion provided.

    The USB Device you are connecting should assert DP (HighSpeed/FullSpeed devices) or DM (Low Speed device) within ~200ms of sensing VBUS_VALID (> =4.7V).

    Please check that the USB Device sees VBUS >= 4.7V and is asserting either DP or DM* in response.

    we tried another device and we get this:

    both of the devices we attached are high speed.

    We think there may be signal integrity issues.

    The bus runs through 4 boards finally land at the port.

    How do I configure the port to use Full Speed and (not High Speed)?

    Thanks Ben. Now I have

    &usb0 {
    status = "okay";
    dr_mode = "host";
    maximum-speed = "full-speed";
};

    Now when I connect HS device, it is never detected (same behavior as previously).

    Next HS device connected gives a tremendous amount of output, and Linux is looping over and over assigning higher and higher device numbers to it:

    The log shows the thumb drive is not enumerated properly, so the kernel SCSI layer driver keeps resetting the device trying to re-enumerate it.

    Unless the thumb drive is corrupted, likely your board has signal integrity problem as you mentioned earlier.
