PYNQ2.6.0 petalinux2020.1 vivado2020.1 for zcu102

PYNQ2.6.0     petalinux2020.1  vivado2020.1  vitis2020.1 for  zcu102     failed   

1、设置相关环境

        git clone https://github.com/Xilinx/PYNQ.git
        cd PYNQ
        git checkout v2.6.0
        git checkout -b ZCU102

        source ./sdbuild/scripts/setup_host.sh

        设置环境：

source /media/ccpiot/cfd852b5-0a53-4e35-8317-4213d7cceef1/xilinx/Vivado/2020.1/settings64.sh
source /media/ccpiot/cfd852b5-0a53-4e35-8317-4213d7cceef1/xilinx/Vitis/2020.1/settings64.sh
source /media/ccpiot/cfd852b5-0a53-4e35-8317-4213d7cceef1/xilinx/Petalinux/2020.1/settings.sh
export PATH=/opt/qume/bin:/opt/crosstool-ng/bin:$PATH

相关环境都设置完毕，执行 make checkenv 查看，通过。

2、把bionic.aarch64.2.6.0_2020_10_19.img  放在prebuild文件夹下

3、在PYNQ/boards下建立ZCU102文件夹，包含xilinx-zcu102-v2020.1-final.bsp和ZCU102.spec

        ZCU102.spec里的内容如下：

ARCH_ZCU102 := aarch64
BSP_ZCU102 := xilinx-zcu102-v2020.1-final.bsp


STAGE4_PACKAGES_ZCU102 := pynq ethernet 

4、在sdbuild文件夹下执行以下命令：

     make BOARDS=ZCU102 PREBUILD=./prebuilt/bionic.aarch64.2.6.0_2020_10_19.img   

        似乎上个命令不行，换成下面的命令：        

make PREBUILT=/media/ccpiot/cfd852b5-0a53-4e35-8317-4213d7cceef1/projects/petalinux_work/PYNQ/sdbuild/prebuild/bionic.aarch64.2.6.0_2020_10_19.img BOARDDIR=/media/ccpiot/cfd852b5-0a53-4e35-8317-4213d7cceef1/projects/petalinux_work/PYNQ/myboards

把 “3、在PYNQ/boards下建立ZCU102文件夹，“换成在PYNQ下建立myboards文件夹，把ZCU102文件夹复制到这个下面

5、编译遇到的问题（已解决）

1、vitis等工具的版本匹配问题，主机如果安装多个版本的vitis等工具，只source用到的版本的settings64.sh就可以

2、主机的python位置问题，查看sdbuild下的Makefile文件中的以下句子，查看主机中执行which python命令，python位置是否与后面的匹配
which python | fgrep /home/ccpiot/anaconda3/bin/python

3、使用crosstool-ng来制作编译工具链时需要下载多个压缩文件，下不下来会出错
需要的文件下载到/media/ccpiot/cfd852b5-0a53-4e35-8317-4213d7cceef1/projects/petalinux_work/PYNQ/sdbuild/build/gcc-mb/.build/tarballs   路径下，自己手动下载，放到此文件夹下


4、编译过程中，在编译镜像时会下载python 各种包 可能会出现包之间版本冲突，在 PYNQ/sdbuild/packages/python_packages_bionic下的qemu.sh文件，内容如下

export HOME=/root

set -x
set -e


cat > requirements.txt <

6、上边的问题解决，编译接着进行，但是后续编译过程出现以下错误，（没有解决）
