您好!
我试图使用一个CYC7C68016A芯片与FX2LP没有EEPROM,我有问题时,我第一次插入它与司机(至少我认为) 我使用WindowsXP 32位,我已经下载了CY3684EZ USB FX2LP开发工具包。 当我第一次插入FX2LP窗口时,会发现一个未知的设备,所以我尝试用CyPress & GT;管理-& gt;CyUSB & gt;CysB.INF文件来更新驱动程序,但是我得到了错误:“指定的位置不包含关于硬件的信息”。 当然,我用VID04B4和PID8613修改INF文件,甚至尝试改变GUID。 然后我注意到,在计算机和GT中,管理和未知设备-GT;设备实例ID具有0000的PID / VID。 我看到它可能来自硬件问题(见EZ-USB(R)FX2LP(TM)和EZ-USB FX1(TM)硬件设计和调试- AN15566)的成功指南,但它仍然不起作用。 我真的不知道下一步该怎么做…… 这是我的INF文件: CyPress通用USB驱动程序用于Windows98Me/3/XP;[Value]签名=“芝加哥$ $”类=36FC9E60-C465-11CF-80564-445 5354000 }提供程序= %提供程序%[源代码DISKSNAMES ] 1=%Cy***Buffice %,,[源代码DISKS文件] CysBMe.Sys= 1 CysB.Sys= 1 CysB.SPD=1[制造商] %MFGNAME% = CyPress [ CyPress ];CyPress FX2LP缺省ID %VIDY04B4&PIDY8613.DEVICESDESCC%= CYUSB,USB VIDY04B4&PIDY8613;CyPress FX1缺省ID;%VIDY04B4&PIDY64 73.

When I plug in for the first time the FX2LP Windows detect an Unknown device so I try to update the driver with the Cypress->Manage->CyUSB->CYUSB.inf file but I've got the error: “the specified location does not contain information about your hardware” I have, of course, modify the inf file with VID04B4 and PID8613 and even try to change the GUID. Then I noticed that in Computer-> Manage->Unknown device->Detail the Device Instance ID has a PID/VID of 0000. I have seen it could come from a hardware problem (see Guide to Successful EZ-USB(R) FX2LP(TM) and EZ-USB FX1(TM) Hardware Design and Debug - AN15456 ) but it still does not work.

嗨,洛卡斯,
VID/PID为0000是硬件问题的提示。你是否遵循了AN1545中的步骤来检查硬件设计是否没有任何问题。 当做, 阿南德 以上来自于百度翻译 以下为原文 Hi lokas, VID/PID coming as 0000 is suggestive of hardware issue. Did you follow the steps in AN15456 to check if the hardware design doesn't have any issues. Regards, Anand |

是的,这个过程
修复DVB-T驱动程序所需的过程如下:1。从PC的USB端口断开你的板。2。如果您对注册表编辑缺乏经验,请在此步骤之前备份注册表。转到注册表(通过在开始…运行ReGEdEt)并找到HKEY-LoalAlxMy/Survivs/CurrnCuttoSt/EnUM/USB文件夹。找到标记为“VIDA04B4&PIDY8613”的键或文件夹。右键单击此键并设置安全权限以启用完全控制。删除密钥和任何子密钥… 但是没有钥匙或文件夹标有“VIDA04B4和PIDY8613”。 以上来自于百度翻译 以下为原文 Yes I followed this process The process required to fix the DVB-T driver issue follows: 1. Disconnect your board from the PC’s USB port. 2. If you are inexperienced with registry editing, back up the registry before this step. Go to the registry (by typing ‘regedit’ in Start…Run) and find the HKEY_LOCAL_MACHINE/SYSTEM/ CurrentControlSet/Enum/USB folder. Locate the key or folder labeled ‘Vid_04b4&Pid_8613’. Right click on this key and set the security permissions to enable full control. Delete the key and any subkeys... But there is no key or folder labeled ‘Vid_04b4&Pid_8613" |

嗨,洛卡斯,
我说的是观察示波器上的CKOUT信号的过程,以确定设计是否正确。你遵守了吗? 当做, 阿南德 以上来自于百度翻译 以下为原文 Hi lokas, I'm talking about the process of observing the CLKOUT signal on the oscilloscope to find out if the design is right. Did you follow that. Regards, Anand |

抱歉耽搁了
没有CK7C68016A(也不是IFCK)的CKOUT。这些引脚只存在于13A和14A上。 所以我不能遵循这个过程… 以上来自于百度翻译 以下为原文 Sorry for the delay There is no CLKOUT for the CY7C68016A (and neither IFCLK). Those pins are just present on the 13A and 14A. So I can't follow this process.... |

我看不出你的原理图有什么问题。
有2个可能的原因 1。这钟不够干净。请检查抖动是否不能够+/-100ppm,并具有适当的摆幅(VIH等参数在数据表中可用)。如果可能的话,请参阅信号并通过波形截图发送。 2。USB线有很大的噪音,在这种情况下,必须审查布局。请看HTTP://www. CyPress。RID=12982,看看您是否符合我们的布局指南。 当做, 阿南德 以上来自于百度翻译 以下为原文 I don't see any issues in your schematic. There are 2 possible reasons 1. The clock is not clean enough. Please check if the jitter is not able +/- 100ppm and has proper swing (VIH etc parameters available in datasheet). If possible please scope the signal and send across a screenshot of the waveform. 2. The USB line has lot of noise, in this case the layout has to be reviewed. Please look at http://www.cypress.com/?rID=12982 to see if you're meeting our layout guidelines. Regards, Anand |

我不认为问题来自时钟,因为我的范围24MHz的时钟,我用(引脚5 XTALIN),它看起来相当干净。
关于USB线没有噪声,它们的电平是3V(d+)和1.7V(d-)。 以上来自于百度翻译 以下为原文 I don't think the problem come from the clock because I scoped the 24MHz clock that I use (pin 5 XTALIN) and it seem pretty clean. About the USB line there is no noise and their levels are 3V (D+) and 1.7V (D-).... |

D-(1.7V)?在D+上会有一个上拉以指示速度,所以D+上的3V是好的,而D应该是0V。然后应该是Chirp序列。你有这个3V和1.7V场景的范围信号吗?
当做, 阿南德 以上来自于百度翻译 以下为原文 D- (1.7V)?? There will be a pull-up on D+ to indicate speed so the 3V on D+ is fine but D- should be 0V. Then there should be chirp sequence. Do you have the scoped signal of this 3V and 1.7V scenario. Regards, Anand |

您好!
事实上,你是对的,我的针脚D出了问题,应该是0V。 我的设备终于被认可了。 谢谢你 以上来自于百度翻译 以下为原文 Hi Indeed you were right I had a problem with the pin D- it should have been at 0V. My device is finally recognized. Thank you |
