这个Demo在PYNQ v2.7image和vivado 2020.2上实现了dynamic partial reconfiguration

参考了以下资料：

用到的tcl命令：

set_param project.enablePRFlowIPI 1

set_param bitstream.enablePR 2341

set_param hd.enablePR 1234

set_property PR_FLOW true [current_project]

create_reconfig_module -name rm_sub -partition_def [get_partition_defs pd_0] -define_from rm_sub

没有搞清楚的问题：

1.为什么部分位流加载之后查询到的IP是None？

2.pr里边的rm的address应该怎么配置

3.https://www.xilinx.com/support/documentation/sw_manuals/xilinx2021_2/ug909-vivado-partial-reconfiguration.pdf 第4章P87 P88 P89

4.Partial Reconfiguration Decoupler是怎么用的

5.视频中提到的如果只有一个pr读写mmio时会死机的问题
