d12能枚举和不能枚举对比

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:

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？

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??

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??????

2007-9-27 20:50

贴图庆祝一下先!

2007-9-27 21:51

你的那个程序要枚举成D12开发板要改那些地方?

2007-9-28 16:24

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

我以前做过一个带串口的板子，目的就是想观察枚举过程。

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

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!

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!

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

描述符该成跟周立功的一样,可是枚举第一步就过不去

涓涓之细流
