怎么使用CY7C68013A-56PVXC修复USB摄像机

您好,我有一个问题,USB摄像头,使用芯片CY7C68013A 56PVXC:
相机没有响应,当连接到PC & GT时,我替换了XTAL -没有变化。我在PCB上没有看到损坏的部件或轨道。1V8和2V8测试点的电压是可以的。相机的显示器为我提供更换PCB,但我想先尝试修理。我有一台第二台工作摄像机,硬件完全一样。是否有可能购买新的芯片CY7C68013A 56PVXC,PCB上的焊料,并从工作摄像机复制固件代码?在CY7C68013A—56PVXC中是否存在复制保护,这将防止固件从一个芯片复制到另一个芯片?提前感谢!瓦伦丁

  Hello,

I have a problem with USB video camera, that uses chip CY7C68013A-56PVXC :
     
     
   

> Camera not responding, when are connected to the PC.
> I replaced a XTAL - no change.
> I don't see broken components or tracks on PCB.
> Voltages of 1V8 & 2V8 test points are OK.
> Manifacturer of camera offer me replacement PCB, but I want to try repair first.

I have a second, working camera with exactly the same hardware.

> Is it possible to buy new chip CY7C68013A-56PVXC,
solder on PCB and copy firmware code from working camera?

> Is it exist copy protection in CY7C68013A-56PVXC,
that will prevent duplicating of firmware from one chip to another ?

Thanks in advance!
Valentin

由于大多数赛普拉斯芯片的CY7C68013A有能力从读取配置数据或程序代码的保护。我猜想你的相机制造商已经做到了。另一个值得怀疑的事实是:如果CY7C68013A是缺陷,WHO保证读取任何数据都会产生有用的结果。

  As most Cypress-chips the CY7C68013A has the ability to be protected from reading-out configuration-data or program-code. I would assume that the manufactor of your camera has done that. Another questionable fact is: if the CY7C68013A is defect, who guarantees that the reading of any data would deliver a useful result.

由于大多数赛普拉斯芯片的CY7C68013A有能力得到保护…
也许芯片是受保护的,我听到了同样的说法。
来自工程师,在柏树当地贸易办公室工作。
但因为只有理论,所以我决定要求更多的细节。:)
另一个值得怀疑的事实是:如果CY7C68013A是缺陷,
世卫组织保证任何数据的读取都会产生有用的结果。
我有第二,全工作相机与相同的印刷电路板修订,这大概
可以用作源程序。但是当内部代码不可读时,
我会考虑订购备件。解决方案,至少3倍昂贵。:(
不管怎样,谢谢你的回答。:)

    Probably chip is protected, the same statement I heard
    from engineer,  working in local trade office of Cypress.
    But because there are only theories, I decide to ask for more details. :)
    Another questionable fact is: if the CY7C68013A is defect,

    who guarantees that the reading of any data would deliver a useful result.
    I have second, full working camera with same PCB revisions, which probably
    can be used as source. But when internal code is not readable,
    I will think about ordering of spare parts. Solution, at least 3x times expensive. :(
    Anyway, thank you for the answer. :)
