如何使用Spansion S25FL129P间接编程Spartan6

您是说您正在设计新的电路板还是您已经收到了新的电路板？
我在SPI单模式下使用了Spansion S25FL32P和Spartan 6，但Spansion数据表说它可以在双模式或四模式下使用它。
如果该设备与iMPACT兼容，那么我相信您可以在任何模式下使用它。
你打算在配置后使用内存吗？
你需要一个特别快速的配置时间，但是没有用于具有更广泛存储器的BPI模式的电路板空间吗？坦率地说，为了我的钱，必须有一些令人敬畏的理由在另一种模式下使用简单的SPI存储器而不是单一的
SPI模式纯粹是因为它似乎只是引入了出错的机会。
无论如何，iMPACT允许您在将编程文件与内存关联时选择PROM的数据宽度。

以下为原文

Do you mean you are designing a new board or that you have received a new board?
 
I have used the Spansion S25FL32P with a Spartan 6 in SPI single mode but the Spansion datasheet says that it is possible to use it in Dual or Quad mode. If the device is compatible in iMPACT then I'd be confident that you can use it in any mode.
 
Do you intend to use the memory after configuration? Do you need an especially rapid configuration time but don't have the board space for BPI modes with wider memories?  Frankly, for my money, there'd have to be some awesomely compelling reason to use a simple SPI memory in another mode than single SPI mode purely because it just seems to introduce opportunities to go wrong.
 
Anyway, iMPACT allows you to select the data width of the PROM when associating a programming file with the memory.

我们的新电路板仍处于设计阶段。
由于没有配置时间约束，因此选择了简单的SPI。
将使用间接编程模式。
感谢您的回答。
我不太了解Impact，我知道数据总线大小可调，我感觉更好。



以下为原文

Our new board is still in design phase. As there is no configuration time constraint simple SPI is chosen. Indirect programming mode will be used.
Thanks for your answer. I do not know very well Impact and I feel better knowing that the data bus size is adjustable.

您好@jxparis，我建议您看一下影响帮助。

值得注意的是，通过使用Spartan 6进行iMPACT，您将需要使用间接编程。
我不相信某些家庭和后来的IMPACT版本存在直接编程。
同样值得注意的是，一旦您设计了硬件并且制造了电路板，您就可以选择配置方法。
如果您认为您可能想尝试Quad访问内存，则必须立即进行设计。
如果你只设计单宽度SPI那么你将会遇到这种情况（当然这可能不是问题）。
我的观点是你应该研究你的选择，理解它们然后相应地进行设计。
这样，当硬件到达时，您将避免令人不快的意外。

以下为原文

It's probably worth bearing in mind that, through iMPACT with a Spartan 6, you will HAVE to use indirect programming. I don't believe that direct programming exists for some families and later IMPACT versions.
 
It's also worth bearing in mind that once you design your hardware and your board is manufactured your choice of configuration method is pretty much fixed. If you think that you might want to try Quad access to the memory, you have to design it in now. If you only design single width SPI then that's what you will be stuck with (and that may not be a problem, of course).
 
My point being that you should research your options, understand them and then design accordingly. This way you will avoid unpleasant surprises when the hardware arrives.
