如何从PROM闪存和SPI闪存配置FPGA的PDF文件？

嗨，我认为你指的是间接SPI编程。
在间接SPI编程中，不直接通过影响对闪存进行编程。
相反，影响通过FPGA将指令和编程数据（.mcs）发送到SPI。在此过程中，影响首先使用.cor文件对FPGA进行编程。
.cor文件包含编程SPI闪存所需的逻辑。
这个逻辑是Xilinx专有的。
当您点击程序闪存时，fpga配置了.cor文件，然后影响将通过JTAG将.mcs文件发送到FPGA，然后FPGA处理数据并最终配置flash.Regards，Krishna

以下为原文

Hi,

I think you are referring to indirect-SPI programming.

In indirect SPI programming, you don't program the flash directly through impact. Instead the impact sends the instructions and the programming data (.mcs) to SPI through FPGA.

During this process, the impact first programs the FPGA with a .cor file. The .cor file consists of the necessary logic to program a SPI flash. This logic is Xilinx proprietary.

When you click on program flash in impact, the fpga gets configured with .cor file and then the impact will send the .mcs file through JTAG to FPGA and then the FPGA processes the data and will eventually configure the flash.

谢谢，请详细解答。
另一个问题，你能告诉我主串口模式怎么样？



以下为原文

Thanks, smarell for your detailed answer.
another question ,Could you tell me what about Master serial mode ?

在串行/选择映射模式下，PROM将与FPGA一起位于JTAG链中。
因此，我们使用JTAG线通过影响对PROM进行编程。

以下为原文

In serial/selectmap mode, the PROM will be in the JTAG chain along with FPGA. Hence, we program the PROM through impact using JTAG lines.-----------------------------------------------------------------------------------------------

假设当前模式是主模式并且我从IMPACT中选择“程序”选项，那么FPGA将在平台闪存中配置，是吗？
如果是，如果选择是“PROGRAM FPGA和FLASH”，IMPACT将会有什么不同。
提前致谢。



以下为原文

Assume if the current mode is Master serial mode and i select "Program" option from IMPACT the FPGA will be configured wilthout the Platform Flash ,is that right ?
if yes,what is the diference the IMPACT will do if the selection is "PROGRAM FPGA and FLASH".
Thanks, in advance. 

初始化JTAG链时，您将看到PROM和FPGA。
要对PROM进行编程，您需要右键单击并编程PROM。
关闭电路板并打开电源后，FPGA将根据存储在PROM中的映像进行配置。

以下为原文

When you initialize the JTAG chain, you will see a PROM and FPGA. In order to program PROM, you need to right click and program the PROM. Once you poweroff and power-on the board, the FPGA gets configured from the image stored in PROM.-----------------------------------------------------------------------------------------------

这是我的意思，
我知道Platform Flash和FPGA共享“TCK”和“TMS”线以及FPGA“TDO”线连接到Platform flash“TDI”线，因此IMPACT如何在没有Platform Flash的情况下配置FPGA。



以下为原文

Here is what i mean,
i know that Platform Flash and FPGA shares "TCK" and "TMS" lines and FPGA "TDO" line connected to Platform flash "TDI" line , so how IMPACT configures  FPGA only without Platform Flash. 

您可以“绕过”PROM，然后在iMPACT中配置FPGA。

You can "bypass" the PROM and then configure the FPGA in iMPACT.
