   import os
   import tarfile
   
   def recursive_files(dir_name='.', ignore=None):
       for dir_name,subdirs,files in os.walk(dir_name):
           if ignore and os.path.basename(dir_name) in ignore: 
               continue
   
           for file_name in files:
               if ignore and file_name in ignore:
                   continue
   
               yield os.path.join(dir_name, file_name)

9. How to use XRFdc_IntrClr in PYNQ

   (“A RFdc object”)._call_function(“IntrClr”, 0, 0, 0, 4294967295)
   //The first 0 indicates that you are setting up an ADC, the second one indicates that you are setting up the tile 0 of the ADC and the last indicates the block number of the tile.

10. 内存分配

    https://discuss.pynq.io/t/pynq-maximum-allocatable-memory-cma/1593/5

    https://github.com/Xilinx/PYNQ/pull/1424

问题

1. 构建RFSoC-PYNQ遇到IP核授权问题，需要申请该IP授权

   

2. 为什么Overlay没download？

   #pynq\pynq\overlay.py
   def __init__(
       self, bitfile_name, dtbo=None, download=True, ignore_version=False, device=None, gen_cache=False
   ):

3. 编译

   安装Vivado petaLinux 2022.1

   #克隆仓库
   git clone --recursive https://github.com/Xilinx/RFSoC-PYNQ.git
   #安装petaLinux
   chmod 755 ./petalinux-v2022.1-04191534-installer.run 
   ./petalinux-v2022.1-04191534-installer.run
   #假设安装到/home/pc/Xilinx/
   source /home/pc/Xilinx/settings.sh

   打开Makefile 添加

   image: checkenv_rfsocpynq gitsubmodule ${PREBUILT_SDIST_DST} ${PREBUILT_ROOTFS_DST} checkenv_pynq ${IMAGE}
     @echo ""
     @echo "  RFSoC-PYNQ completed building image: ${IMAGE}"
     @echo ""

   make BOARD=ZCU208 image

4. 加入ILA检测不到

   

   使用ILA后 时钟配置和Overlay加载有先后顺序

   #zcu208
   xrfclk.set_ref_clks(lmk_freq=245.76, lmx_freq=491.52)
   base = Overlay(bit_path,ignore_version=True)

5. hwh没有IP核 在bd Address editor里Unsign后重新分配

6. 增加Jupyter笔记本的内存限制

   Jupyter笔记本电脑具有默认的内存限制大小。您可以按照以下步骤尝试增加内存限制：
   1)使用命令生成配置文件：

   jupyter notebook --generate-config

   2)打开位于" jupyter"文件夹内的jupyter_notebook_config.py文件，然后编辑以下属性：

   NotebookApp.max_buffer_size = your desired value

   请记住在属性值之前删除"＃"。
   3)保存并运行jupyter笔记本。
