怎么使用AXI Quad SPI IP Core对带有PROM文件的SPI Flash进行编程

你好，
我有一个设计，我希望能够在初始编程后更新SPI配置闪存上的PROM文件。
到目前为止，我的研究表明，在完成FPGA编程后，应该可以与配置spi flash连接。
在我的设计中，我有一个内存映射AXI总线，由AXI主机（PCIe）控制，从主机PC接收其事务。
我的想法是能够通过PCIe链路发送PROM bistream到使用新PROM文件对SPI闪存进行编程的AXI Quad SPI IP Core  - 这应该是可能的，对吗？
如果我错在某处，请纠正我，因为我很不高兴。
我现在的问题是，在将PROM文件解析为SPI闪存之前，PROM文件应该采用哪种格式，在将其发送到SPI Flash之前是否需要对PROM文件（MCS）进行任何解释？
先谢谢你！

Hello,

I have a design where i wish to be able to update the PROM file on the SPI Configuration Flash after initial programming. My research so far has showed that it should be possible to interface with the configuration spi flash after the FPGA is finished being programmed from it.

On my design i have a memory mapped AXI bus that is controlled from an AXI master (PCIe) that receives its transactions from a host PC.

My idea is the be able to send PROM bistream over the PCIe link, to the AXI Quad SPI IP Core that programs the SPI flash with the new PROM file - This should be possible, right? Please correct me if i'm wrong somewhere as i'm pretty new to alot of this.

My question now is, which format should the PROM file be in before parsing it over to the SPI flash and do i need to do any interpretation of the PROM file(MCS) before sending it to the SPI Flash?

Thank you in advance!
