usb gadget请教，有做过这块的大侠进来瞧瞧

myitlover

小弟刚入门不大懂  ，想请教一下

我现在做这块的驱动，

usb 模拟成优盘   不成功，一开始还能出现盘符  就出现过一次，现在都是找不到驱动

insmod s3c2410_udc.ko后出现
0.00 USB: s3c2410_udc: version 30 Apr 2006
0.01 USB: s3c2410_udc_probe
0.02 USB: udc_disable called

insmod g_file_storage.ko file=/root/data/backing_file后出现
0.03 USB: usb_gadget_register_driver() 'g_file_storage'
0.04 USB: binding gadget driver 'g_file_storage'
0.05 USB: s3c2410_set_selfpowered()
g_file_storage gadget: File-backed Storage Gadget, version: 28 November 2005
g_file_storage gadget: Number of LUNs=1
g_file_storage gadget-lun0: ro=0, file: /root/data/backing_file
0.06 USB: udc_enable called

连接开发板和PC

终端提示死在g_file_storage gadget: full speed config #1
没找到原因，我想做下转串口的   因为我的模块都是同时编译出来的

我是照着gadget_serial.txt来做的

首先建立设备节点

mknod /dev/ttygserial c 127 0

insmod s3c2410_udc.ko后出现
0.00 USB: s3c2410_udc: version 30 Apr 2006
0.01 USB: s3c2410_udc_probe
0.02 USB: udc_disable called

insmod g_serial.ko use_acm=1
提示忘了copy了

然后安装pc主机端驱动，用的是该文件给的usbser.sys文件

和windows自带的usbser.sys

在C:\WINDOWS\Driver Cache\i386\driver.cab下解压而来

装好驱动后，连接开发板和主机，照到模拟的端口号是com7

新建一个超级终端设置串口，打开以后

原来串口的超级终端输出

关闭的时候也有提示... serviced SETUP_END ...



可是不知道如何传送文件，这样做了以后怎么通信



还有就是里面一段话不懂  

Testing with Minicom or HyperTerminal
-------------------------------------
Once the gadget serial driver and the host driver are both installed,
and a USB cable connects the gadget device to the host, you should
be able to communicate over USB between the gadget and host systems.
You can use minicom or HyperTerminal to try this out.

On the gadget side run "minicom -s" to configure a new minicom
session.  Under "Serial port setup" set "/dev/ttygserial" as the
"Serial Device".  Set baud rate, data bits, parity, and stop bits,
to 9600, 8, none, and 1--these settings mostly do not matter.
Under "Modem and dialing" erase all the modem and dialing strings.On a Linux host running the ACM driver, configure minicom similarly
but use "/dev/ttyACM0" as the "Serial Device".  (If you have other
ACM devices connected, change the device name appropriately.)

On a Linux host running the USB generic serial driver, configure
minicom similarly, but use "/dev/ttyUSB0" as the "Serial Device".
(If you have other USB serial devices connected, change the device
name appropriately.)

On a Windows host configure a new HyperTerminal session to use the
COM port assigned to Gadget Serial.  The "Port Settings" will be
set automatically when HyperTerminal connects to the gadget serial
device, so you can leave them set to the default values--these
settings mostly do not matter.

With minicom configured and running on the gadget side and with
minicom or HyperTerminal configured and running on the host side,
you should be able to send data back and forth between the gadget
side and host side systems.  Anything you type on the terminal
window on the gadget side should appear in the terminal window on
the host side and vice versa.



红色部分是什么意思，怎么实现呢？我用的是windows下的环境  用超级终端

myitlover

没人知道吗？

albcamus

就是让你制定minicom使用那个设备做串口， 而不使用标准的/dev/modem或者/dev/ttyS0。

windows不懂。

myitlover

这个我知道的   
On the gadget side run "minicom -s
这个怎么实现的

crifan

那段程序意思是，去Linux系统上，用一个终端程序，比如他说的minicom，当然也可以用其他的，
然后设置的时候，将串口设备设置成/dev/ttygserial，意思就是，你驱动工作OK的话，连上Linux，
系统创建了这个设备，对应的就是你的USB转出来的串口了。

同理，Windows下，也是要找到对应的你这个USB转出来的串口，
然后用一个终端程序去试试，看看有无输出，是否工作正常。
Windows下，右键”我的电脑“，属性，硬件，设备管理器
如果你的USB转串口工作正常，应该在”端口(COM和LPT)“下面看到对应的设备的。

关于这点，我是之前用过USB转串口线，连上Windows正常后，就会出现对应设备的。

你上面说了，超级终端，也可以工作的，但是不知道如何传送文件。

我之前遇到的，是在板子里面已经安装了lrz/lsz 或者 rz/sz 工具的，

你这个，我记得超级终端里面是右键窗口中，有选择传输文件的吧。
或者你换SecureCRT试试，那个会更好用些。

如果哪里说错了，希望高手指正。。。。
