f1c100s USB otg device 模式可以用吗？

szyusong · 2018-09-11 11:27:34

进 device 模式，能调用 USBC_EnableDpDmPullUp，但是 D+ 脚没有拉高，所以接电脑没反应。请各位大神指点下，多谢了！

还没有用过 USB, 路过

你是怎样进入device模式的？

我也在搞f1c100s的device模式，驱动加载都没问题，就是usb插电脑没反应
尝试过改设备树文件，强制指定device模式，都没有效果
udc的状态明显没识别usb端口状态
不知道是不是要指定vbus_det 的管脚？

你是用主线 linux 吗?
据说主线linux 还没驱动 usb.

用的是bsp内核

我向SUNXI Linux小组提交了一个关于USB支持的问题。还在等待回应。

我觉得这个版本的 bsp linux 驱动 usb device 不改肯定是不行的，连时钟都没有配置.

修改 sunxi_usb_device_enable：

	is_udc_enable = 1; // 添加这句 ！！！

	if (udc->driver && is_udc_enable) {
		sunxi_udc_enable(udc);
		cfg_udc_command(SW_UDC_P_ENABLE);
	}

	DMSG_INFO_UDC("sunxi_usb_device_enable end\n");

这样改完, device 就可以跑起来了？

可以枚举，但是我测试 RNDIS 还有问题，INT 节点通讯有问题。

其他的CDC, AUDIO有没有测试?

没有，我比较关心 RNDIS，这个通了就相当于有个网卡了，调试东西会方便很多。

但是如果接 linux 的主机，RNDIS 是可以的，就是在 Windows 下不行。

这样哦，那说驱动 usb device 问题不大了，昨天一直纠结的 usb device 时钟没有配置不知道是什么问题了？

usb device 能工作的。在 dts 中配置 usb_port_type 为 2 就可以

		usbc0:usbc0@0 {
			device_type = "usbc0";
			compatible = "allwinner,sunxi-otg-manager";
			usb_port_type = <2>; /* 0: for device, 1: for host */
			usb_detect_type = <1>;
			usb_detect_mode = <0>;
			//usb_id_gpio = <&pio PD 9 0 1 1 1>;
			usb_id_gpio = <&pio PE 2 0 1 1 1>;
			//usb_det_vbus_gpio = <&pio PD 10 0 1 1 1>;
			usb_det_vbus_gpio = <&pio PE 2 0 1 1 1>;
			//usb_drv_vbus_gpio = <&pio PD 11 1 1 1 1>;
			usb_host_init_state = <0>;
			usb_regulator_io = "nocare";
			usb_wakeup_suspend = <0>;
			usb_luns = <1>;
			usb_serial_unique = <0>;
			usb_serial_number = "20080411";
			rndis_wceis = <1>;
			status = "okay";
		};

多谢指教，那可以动态切换吗？

有空我也试一试 windows 下 RNDIS 问题.

你指的OTG? 应该是可以的。还没时间验证。

是的，在运行中动态切换OTG的device与host模式,插入U盘就要识别成U盘，插入电脑就要进入device模式.

感觉有点问题，0.623秒的时候加载了g_ether的模块，但6.48秒的时候才加载usb device的驱动，顺序是不是反了？g_ether模块应该是依赖usb_device驱动，应该在后面加载的

@szyusong 感谢分享!

你用的是主线 u-boot + bsp linux 吗？如果全部按照官方bsp的做法，应该是改 sys_config.fex 设备树的, 改dts 好像起不到作用。

对，我就是从那里克隆的.

cd /opt/c600
./build.sh config ###配置
./build.sh -p sunivw1p1 -k linux-3.10 -m all ###编译
./build.sh pack ####打包

你是用这个流程编译的吗?

szyusong · 2018-09-21 13:55:23

我把 kernel 目录抠出来单独编译的。就是那个 linux-3.10 目录。

原来如此，大神是否方便提供一个能用OTG的flash固件?

看来我的不太一样，错误是 udc->driver is null

我的也一样, 哭

我把 kernel 目录抠出来单独编译的。就是那个 linux-3.10 目录。
原来如此，大神是否方便提供一个能用OTG的flash固件?

我按你上面的修改，出现这个错误.

不要编译为 module，直接和内核编译在一起试试。

直接编译到内核，模块方式暂时不行，问题未知。

Ubuntu Linux 跑 RIDIS 基本正常。

Win7 枚举正常，得找个驱动装装.

权威答案:

我终于想通了。
由于响应时间的原因，设备未能成功完成某些信息的枚举。IE usb设备在枚举期间没有响应足够的时间。
一旦我修复了这个问题，我就能成功运行设备而不会出现ErrorCode 10问题。

我的驱动，用licheepi zero+linux-4.13.0的内核是可以正常使用的，看来3.10这个版本还是有不少坑

ippen · 2018-09-23 00:19:22

我现在测试的情况更悲剧，我要用mass_storage,按上面 @szyusong 大师的方法该了代码和配置，usb插入pc后，仍然毫无反应。
用g_serial就有反应，看样子cdc驱动是可以的，但mass_storage就不行了

晕哥 · 2018-09-23 06:47:14

linux 3.10 是LTS长支持版本，如果是gadget驱动引起，应该可以打上补丁包解决这个问题。

在 Windows 下可以使用 Bus Hound 抓包分析，我前面的帖子有写抓包的内容，问题出在中断节点 0x84 无法传输数据造成的。Windows下 RNDIS 驱动需要通过中断节点获取 device 的网卡状态变化及数据是否就绪等信息，因此中断节点无法通讯，RNDIS 就无法使用。而 RNDIS 在 Linux 下使用时，好像不会用到中断节点，所以没问题。

果然足够蛋疼
明显是sunxi的udc驱动问题
我在本贴的24楼曾经发过疑问，加载驱动的顺序问题，结果在usb_manager.c里面找到一段代码

static int usb_hardware_scan_thread(void * pArg)
{
        struct usb_cfg *cfg = pArg;

        /* delay for udc & hcd ready */

        msleep(3000);

        while(thread_run_flag) {
                msleep(1000);  /* 1s */

                if (atomic_read(&thread_suspend_flag))
                        continue;
                usb_hw_scan(cfg);
                usb_msg_center(cfg);
        }

        thread_stopped_flag = 1;
        return 0;
}

里面先是延时3秒，然后循环里面又延时一秒，所以g_mass_storage初始化的时候，usb还没完成初始化

我在msg_init里面插入一个4.5秒延时，结果usb插入pc有反应了

nano我也没搞定，zero 用的是主线内核，所以没问题，如果你有zero的板子，可以下载主线内核测试，比较简单，选好参数就可以，没有任何特殊设置和代码改动

3.10 内核的 RNDIS 搞定了。

bi-directional transfers (Endpoint1, Endpoint2)

在 windows 下安装 RNDIS 驱动只需要用 kernel 目录下的 Documentation/usb/linux.inf 手动安装就可以。

按 @szyusong 大神 62#的修改, 装上 52# 的驱动, 看起来终于正常了!
接下来配个ip通讯试一试.

这个是 olimex 在 github A10-OLinuXino-Lime_Rev_A.pdf 原理图, 上面三个引脚都有的.

我手上这个是licheepi nano, 从原理图Lichee_nano.pdf上面看，只有 usb_id, 其他两个脚是没有的. 但是我修改 sys_config.fex :

usb_id_gpio = port:PE02<0><1><default><default>

仍然无法正常检测device或者host.

按 @szyusong看到的手册，f1c100s是3 个endpoints，而我们找到的bsp是f1c600的，c600是8 个endpoint，所以这两者的差异，导致usb 驱动不能通用
应该要找f1c100s专用的bsp

晕哥 · 2018-09-26 14:34:28

在Q群听说 f1c100s, f1c600是同一个 die, 在封装芯片的时候某些IO上拉下拉就成为了另外一个型号，在不开源的u-boot里面区分开来.

听说而已，仅供参考.

f1c100 和 f1c100s 肯定是共一个die 无疑了，
只是f1c100s 封装了一个 32M DDR,
可能引出来的pin没有 f1c100多.

如果这样，那么f1c600就是不同芯片了，因为c600 usb部分写着8 user-configure endpoint

如果f1c100s和f1c100相同，找f1c100的bsp看看应该有帮助

	.ep[3] = {

#if 1
		.bmAttributes	    = USB_ENDPOINT_XFER_INT,
#else
		.bmAttributes	    = USB_ENDPOINT_XFER_BULK,
#endif

是在sunxi_udc.h和sunxi_udc.c里修改吗？
