slave serial模式如何加载partial reconfiguration bit文件?

Jump to solution

芯片是A7,做了一个partial的bit版本,和一个总版本bit文件,总的版本可以通过反转PROGRAM_B,然后SPI串行MOSI数据流。partial的bit文件如何处理?需要反转PROGRAM_B吗?拉低PROGRAM_B会清空FPGA的配置,static部分也丢失了。

不反转PROGRAM_B,感觉SPI串行MOSI数据流没有效果,没有把partial版本加载进去?

应该如何操作,slave serial 模式如何加载partial的bit文件。

加载partial当然不能pulse PROG_B。

partial bit一般不能通过SPI接口加载。它可以通过JTAG,或者GPIO读入fpga后,送入ICAP然后达到部分重新加载的功能。

具体你看一个UG909.
