你好,我们需要通过串口烧写挂在FPGA上的S25FL128S,FPGA为Xilinx公司的A7系列。串口程序已有,想问一下有没有烧写的IP或者逻辑程序?我找到有在Altrea的FPGA上烧写的文档  https://www.cypress.com/file/202476/download   ,在Xilinx上有没有类似的呢?谢谢~~

Hi, we need to write the S25FL128S hanging on the FPGA through the serial port. The FPGA is the A7 series of Xilinx. The serial port program is already available. Is there any IP or logic program that is programmed? I found a document https://www.cypress.com/file/202476/download that was writed on Altrea's FPGA. Is there a similar on Xilinx? Thanks~~

你好,可能我之前没有表达清楚。

因为产品需要封装起来,所以我们希望在调试的时候用JTAG接口下载程序,然后封装之后只留下RS422串口,之后的更新通过RS422串口进行。所以需要在FPGA程序加如烧写FLASH的逻辑。但是现在我们手写的程序有些BUG,问一下有没有贵公司提供的例子之类的

我也没找到例子,但是你看看上面(https://www.cypress.com/documentation/application-notes/an98507-connecting-cypress-spi-serial-flash-...)里列出一些Xilinx的文档里有没有你要的例子。
