d12能枚举和不能枚举对比

只看该作者 · 2007-9-25 13:03

我用D12做了两块不同的板,一块是5V系统,CPU工作在70MHz,采用ale来区分命令和数据,D12可以正常枚举,也可以稳定传输数据.另一块是3.3V系统,CPU工作在25MHz,采用A0来区分命令和数据,枚举不能通过,现象是goodlink灯不停闪烁,windows设备管理器也不停刷新,就像正常枚举最后出现D12那一刻一样,但是没有出现D12也不出现"不明设备",好像枚举最后一步出问题的样子(猜想).固件程序基本一致(除地址不同).示波器观察D12的13脚有正常的12M波形输出(猜测D12初始化没问题),读D12的ID也正常.下面把用bus hound抓取的枚举数据帖出来,希望高手指点:我用的是winxp操作系统.前面看帖子说xp看不到全部的枚举数据,那怎样才能看到全部枚举数据?

先贴出能正常枚举的数据:

只是接通了上拉电阻而已。

在输入和输出处理部分用串口将接收到的数据和发送的数据显示出来看看，这样比较容易跟踪。

结果好像是：USB速度太快，导致串口发送堵塞。
话说回来，如果都要用串口调试USB，那不是所有有USB的板子都最好留出一个串口？
我的意思是还有没有其他办法？

谁让你一次把所有的全部串口输出呢，一步一步来，完成一步就去掉一步的输出,在下一阶段家输出语句,

我凭感觉对数据做了一个大概的注释:也许不准确,但是应该就这个意思

下面首先是正确枚举成功的数据:

能够成功枚举的过程大概如下:
读设备状态-读设备状态-清除状态-读设备状态-读设备状态-设定状态-读设备状态-清除状态-读设备状态-读设备状态-设定状态-读设备状态-清楚状态-获取描述符

而不能枚举成功的过程如下:
读设备状态-读设备状态-清除状态-读设备状态-读设备状态-设定状态-读设备状态-清除状态-读设备状态-读设备状态-设定状态-读设备状态-清楚状态-读设备状态

这就可以看到,前面13步都是一样的,并且返回数据也一样,只有最后一步,能枚举的是获取描述符,不能枚举的则是读设备状态.

这是从PC发出来的命令,PC肯定不会错,是不是由于在XP下看不到设定地址前面的数据,所以前面的in包错了我也看不到,导致最后PC发的包不正确??

真正的数据包应该是下面这样子的，而不是那些GET STATUS

下面这些数据是使用BUS HOUND抓的，这个是在WIN2000下抓到的，如果在WINXP下，就看不到设置地址之前的数据。
写了注释下面的部分就是主机和设备之间的数据通信，而其它的则是主机跟根集线器之间的通信数据。

并且是在设置地址之前。bus hound在xp环境下，设置地址之前的数据看不到.

设置地址之前要返回一个设备描述符.

周的代码太繁杂,我看你的那个用52模拟海量存储器的代码稍微简洁一些,所以想在你的基础上调,在以前的好板子(能枚举的板子)上成功了,我想用他枚举成常见的D12设备(跟周的开发板那样),我修改了你的"设备描述符""配置描述符""接口描述符""端点描述",修改成跟周的定义一样,结果还是不能枚举成功,
请问还要修改那些地方??????

你的那个程序要枚举成D12开发板要改那些地方?

也就是DEVICE_DESCRIPTOR就有问题,始终到不了CONFIGURATION_DESCRIPTOR这一步!

d12能枚举和不能枚举对比

相关帖子

下面贴出的是多次枚举不成功的数据

从你这个过程看，应该是第一步的返回设备描述符都没成功

我以前做过一个带串口的板子，目的就是想观察枚举过程。

我的bus hound没法用,就是用串口调出来的

查资料仔细看了一下上述数据如下:

不能正确枚举的数据:

为了突出重点,我只截取一段来注释,完整的数据在1楼和2楼

换一个bus hound 5抓数据,结果一样:

成功的

你所看到的那些，很多是集线器跟HOST之间的数据，看看我抓

用bushound抓D12确实只有很少数据:

而那个不能枚举的板子什么都抓不到!

是啊,所以你的返回有问题。

成功枚举出海量存储器

我在两个板子上跑圈圈的海量存储器那个程序都成功了!

也许你修改的时候哪儿搞错了。

你指那里错了?我修改你的程序错了还是我修改自己的程序错

这个可难说了，可能是描述符不对吧。其它地方都一样的了

描述符该成跟周立功的一样,可是枚举第一步就过不去
