1 背景
Xilinx Vitis可以做standalone程序开发,不过其工程中使用的路径为绝对路径。工程更换位置后编译将会显示错误。例如：源目录为D:/work,复制到同事电脑上放到C:/work(同事电脑只有一个C盘)。利用Vitis打开工程编译会有一堆错误，提示文件找不到。
2 分析
通过分析Vitis工程中有三个工程文件于路径相关:
- xxx_system.sprj 其格式是一个xml文件,其中字段：
- platform 存放.xpfm文件
- xxx.prj 其格式是一个xml文件，其中字段:
- platform 存放.xpfm文件
- location 存放xxx.prj文件路径
- platform.spr 平台文件，其格式是json文件，其中字段:
- platHandOff 存放xsa文件路径
- qemuArgs 存放qemu_args.txt文件全路径，是Vitis配置文件，与Vitis安装位置有关。
- qemuData 存放qemu Data文件路径，与Vitis安装位置有关。
修改说明：
- 将以上文件路径根据新路径(C:/work)替换旧路径(D:/work)即可。
- 如果Vitis安装路径不同，需要更新qemuArgs和qemuData字段对应路径。
3 解决
可以通过手动修改以上文件是可以解决问题，不过手动修改容易出错误。更好的方式是写一脚本来做文件路径替换，这个脚本需要处理xml和json文件。Python语言内置xml和json库，是理想语言选择。
Python脚本如下：
import os
import json
import xml.etree.ElementTree as ET
def get_project_files(path):
sprjfile = ""
prjfile = ""
sprfile = ""
for root, _, files in os.walk(path):
for file in files:
_, ext = os.path.splitext(file)
if ext == ".sprj":
sprjfile = os.path.join(root, file)
if ext == ".prj":
prjfile = os.path.join(root, file)
if ext == ".spr":
sprfile = os.path.join(root, file)
return (sprjfile, prjfile, sprfile)
def get_file(path, filename):
fullfilename = ""
for root, _, files in os.walk(path):
for file in files:
if file == filename:
fullfilename = os.path.join(root, file)
break
return fullfilename
def update_file(filename, value1, newvalue1, value2 = None, newvalue2 = None):
file = open(filename, "r", encoding="ascii")
fileData = file.read()
file.close()
fileData = fileData.replace(value1, newvalue1)
print(value1, " => ", newvalue1)
if value2 != None and newvalue2 != None:
fileData = fileData.replace(value2, newvalue2)
print(value2, " => ", newvalue2)
file = open(filename, "w", encoding="ascii")
file.write(fileData)
file.close()
def update_sprj(sprjfile, path):
tree = ET.parse(sprjfile)
attrib = tree.getroot().attrib
platform = attrib.get("platform", "")
filename = get_file(path, os.path.basename(platform))
filename = filename.replace("\\", "/")
update_file(sprjfile, platform, filename)
def update_prj(prjfile, path):
tree = ET.parse(prjfile)
attrib = tree.getroot().attrib
platform = attrib.get("platform", "")
location = attrib.get("location", "")
platform_filename = get_file(path, os.path.basename(platform))
location_dirname = os.path.dirname(prjfile)
platform_filename = platform_filename.replace("\\", "/")
location_dirname = location_dirname.replace("\\", "/")
update_file(prjfile, platform, platform_filename, location, location_dirname)
def update_spr(sprfile, path, xilinx_qemu_path):
file = open(sprfile, "r", encoding='utf-8')
spr_data = json.load(file)
file.close()
platHandOff = spr_data.get("platHandOff", "")
systems = spr_data.get("systems", {})
platHandOff_filename = get_file(path + "\\board", os.path.basename(platHandOff))
platHandOff_filename = platHandOff_filename.replace("\\", "/")
update_file(sprfile, platHandOff, platHandOff_filename)
if len(systems) == 1:
domains = systems[0].get("domains", [])
if len(domains) >= 2:
qemuArgs = domains[1].get("qemuArgs", "")
qemuData = domains[1].get("qemuData", "")
update_file(sprfile, qemuData, xilinx_qemu_path)
path = 'E:\\g\\work'
xilinx_qemu_path='D:/Xilinx/Vitis/2020.1/data/emulation/platforms/zynq/qemu/'
sprjfile, prjfile, sprfile = get_project_files(path)
print("update file: ", sprjfile) # xml file
update_sprj(sprjfile, path)
print()
print("update file: ", prjfile) # xml file
update_prj(prjfile, path)
print()
print("update file: ", sprfile) # xml json
update_spr(sprfile, path, xilinx_qemu_path)
说明:
- 脚本需要两个参数：
- 工程所在路径的上一路径
- Xilinx的qemu路径
- get_project_files 函数根据工程路径查找三个工程文件。
- update_sprj 更新sprj文件
- update_prj 更新prj文件
- update_spr 更新platform.spr文件
4 使用
4.1 修改路径
E:/g/work路径如下：
.
├── board
└── workspace
├── app_platform
├── app
└── app_system
说明：
- board 文件夹存放xsa文件
- workspace 为工程路径：
- app_platform 为平台路径
- app_system 为系统路径
- app 为应用路径
运行Python脚本
python3 patch.py
update file: E:\g\work\workspace\app_system\app_system.sprj
X:/work/workspace/app_platform/export/app_platform/app_platform.xpfm => E:/g/work/workspace/app_platform/export/app_platform/app_platform.xpfm
update file: E:\g\work\workspace\app\app.prj
X:/work/workspace/app_platform/export/app_platform/app_platform.xpfm => E:/g/work/workspace/app_platform/export/app_platform/app_platform.xpfm
X:/work/workspace/app => E:/g/work/workspace/app
update file: E:\g\work\workspace\app_platform\platform.spr
X:/work/board/app_platform_v1.0.xsa => E:/g/work/board/app_platform_v1.0.xsa
C:/Xilinx/Vitis/2020.1/data/emulation/platforms/zynq/qemu/ => D:/Xilinx/Vitis/2020.1/data/emulation/platforms/zynq/qemu/
