am335x USB配置问题

andarm lin1
Expert 1387 points


目的：

          能够将u盘驱动起来。 

         问题：/dev/目录下没有usb相关的驱动节点出现

背景：

1、使用的是USB0，OTG模式

2、内核上也配置后打印的输出

usbcore: registered new interface driver usbfs
usbcore: registered new interface driver hub
usbcore: registered new device driver usb

NET: Registered protocol family 24
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
usbcore: registered new interface driver cdc_acm
cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters
Initializing USB Mass Storage driver...
usbcore: registered new interface driver usb-storage
USB Mass Storage support registered.
usbcore: registered new interface driver usbserial
USB Serial support registered for generic
usbcore: registered new interface driver usbserial_generic
usbserial: USB Serial Driver core
USB Serial support registered for GSM modem (1-port)
usbcore: registered new interface driver option
option: v0.7.2:USB Driver for GSM modems
mousedev: PS/2 mouse device common for all mice

    你这个打印是am335x侧的吗？

    能不能把完整的过程描述下。谢谢！

    1、是在am335x上跑的。。

    2、将usb0的已经配置好，在内核上将usb驱动给添加了，

    内核启动后，在/dev目录下没有看到与usb相关驱动文件出现。

    不好意思，我有点没明白你的想法。

    您说的/dev下usb的节点，问题是，如果是u盘，那么usb的节点不是在/dev下有usb的，而是sdbx的节点。

    貌似没有sdbx节点。那应该修改什么。

    1. 请问您在内核文件做了哪些修改? 用的是哪个版本的sdk？

    2. 请问您用的是哪个口？ 硬件电路设计是怎样的？

    1、内核基于天嵌开发板的内核。所以改动还是挺多的，加上我自己也有改动。//现在是要确定改动那些才能生成/dev下的节点文件。

    对比一下（1）电源供电正常。（2）引脚使用也是一样的。

    估计： 是某些usb配置还没有开启。导致没有/dev/下没有相关节点。

    2、使用的是usb0

    参考am335x貌似 usb的相关配置都配置了。。

    但是插入的U盘，/dev下没有sdax文件。求指导方法。

    可以贴下你的board-am335xevm.c 文件吗？看看你对usb口的配置。

    usb上的配置主要是

    static void usb0_init(int evm_id, int profile)
    {
    setup_pin_mux(usb0_pin_mux);
    return;
    }

    static struct pinmux_config usb0_pin_mux[] = {
    {"usb0_drvvbus.usb0_drvvbus", OMAP_MUX_MODE0 | AM33XX_PIN_OUTPUT},
    {NULL, 0},
    };

    {usb0_init, DEV_ON_BASEBOARD, PROFILE_ALL},

    我看到您似乎删了一些源码，我看到前面删掉的源码有个地方有问题：

    static struct omap_musb_board_data musb_board_data = {
        .interface_type = MUSB_INTERFACE_ULPI,
        /*
         * mode[0:3] = USB0PORT's mode
         * mode[4:7] = USB1PORT's mode
         * AM335X beta EVM has USB0 in OTG mode and USB1 in host mode.
         */
        .mode           = (MUSB_HOST << 4) | MUSB_OTG,
        .power      = 500,
        .instances  = 1,
    };
    您可以改为
    .mode           = (MUSB_HOST << 4) | MUSB_HOST ,

    然后看看结果如何

    按照你说的修改了，还是不行。

    你看看id脚是不是拉地了，另外，看看vbus是否正常5v供电了。

    对于内核配置，不知道是否按照下面的文档做了正确的配置：

    http://processors.wiki.ti.com/index.php/UsbConfigHostMSC

    1、usbid 已经接地

    2、vbus 测试过是5V供电。

  • 0 回复 Jian Zhou

     根据网页上的配置也没有问题了。

    发现/sys文件夹里面没有关于usb的任何文件。。这个是自动生成的吗？还是怎样？

  • 0 回复 andarm lin1
    TI__Mastermind 25020 points

    确认一点，在你的硬件电路上面，R254这个0欧电阻焊了吗？如果焊了，去掉试试。

    这个电阻焊上去了后，会把VBUS和VCC的5V连在一起，这样VBUS就不是受到drvbus的信号控制了。vbus直连5V输入的时候，需要一个patch才能正常工作。

    1、你说的patch是？

    2、/sys目录下的usb目录和proc/bus下usb目录都是内核自动生成，还是怎样的。

  • 0 回复 andarm lin1
    TI__Mastermind 25020 points

    这是针对usb0_vbus被直接连接到了5V电源输入上的设计，做出的一个解决方案。如果没有的话，在一些客户那边遇到过无法正常识别的问题。

    可以参考这里：http://e2e.ti.com/support/arm/sitara_arm/f/791/p/333490/1163908

    不过，根据你上面提供的电路，建议你直接把R254去掉，然后进行尝试，这个就和我们的标准设计是一样了。

  • 0 回复 Steven Liu1
    Expert 1387 points

    貌似去掉R254后，能够在/sys/bus/下和/proc/bus下面找到usb目录。

    但是在/dev/下没有u盘相关的设备节点。。目前是已经插入u盘的了。

  • 0 回复 andarm lin1
    TI__Mastermind 25020 points

    这种情况下，能否在插入、拔出U盘的时候，用dmesg打印一下两段的log，然后传上来。

  • 0 回复 Steven Liu1
    Expert 1387 points

    现在拔插U盘没有任何反应，dmesg打印的是开机启动信息而已。

    我前面提到的改驱动的地方改了吗？

  • 0 回复 Yaoming Qin
    Expert 1387 points

     从内核打印信息上看，usb驱动的信息已经配置完了。

    节点和热拔插没有实现。

    您用的文件系统是什么？可以把ti发布的挂上去看看

  • 0 回复 Yaoming Qin

    我使用tq开发板文件系统。目前还没有尝试挂ti发布的ubi文件系统。

  • 0 回复 Yaoming Qin

    经过前面的修改有新现象出现了。 

    1、使用lsusb 会打印下面信息

    Bus 001 Device 001: ID 1d6b:0002

    2、在/dev/目录下出现usbdev1.1设备文件。

    问题1：现在的问题是这usb口是通了吗？

    问题2：u盘为什么没有被挂载？

  • 0 回复 andarm lin1
    TI__Mastermind 35157 points

    您敲下命令mount看看

    谢谢TI朋友的指导。问题已经解决了？

    1、将R254去掉vbus就会不能正常供电了。

           我用万用表测试到的电压为0V

    2、配置usb之前有某一个步骤忽略了。导致的错误。//重新跟了一遍

    正常配置后，便能够在系统上看到相关的文件。
