最小系统zynq petalinux移植学习

安装完petalinux16.4后，按照15.4经验要source 一下SDK目录下的setting的shell

安装vivado在家目录，但是必须要root权限，重点是发现安装后桌面竟然没有软件图标，

桌面快捷方式按照baidu的方法，切换到root账户，进入/usr/share/applications

vim vivado.desktop文件，写入

[Desktop Entry]
Encoding=UTF-8
Name=SDK 2016.4
Comment=SDK 2016.4
Exec=/home/vision/pkg/SDK/2016.4/bin/xsdk
Icon=/home/vision/pkg/SDK/2016.4/data/sdk/images/sdk_logo.png
Terminal=false
StartupNotify=true
Type=Application
Categories=Application;Development;

保存

vim SDK.desktop文件，写入

[Desktop Entry]
Encoding=UTF-8
Name=Vivado 2016.4
Comment=Vivado 2016.4
Exec=/home/vision/pkg/Vivado/2016.4/bin/vivado
Icon=/home/vision/pkg/Vivado/2016.4/doc/images/vivado_logo.png
Terminal=false
StartupNotify=true
Type=Application
Categories=Application;Development;

保存

具体含义可以百度，vivado安装目录是/home/vision/pkg/，然后桌面搜索到快捷方式，拖拽到桌面。发现SDK运行不了

****** Xilinx Software Development Kit

Launching SDK with command /home/vision/pkg/SDK/2016.4/eclipse/lnx64.o/eclipse -vmargs -Xms64m -Xmx512m -Dorg.eclipse.swt.internal.gtk.cairoGraphics=false

百度SDK16.04启动问题，找到17年3月份的解决方法比国外说的的简单明了，无耻复制黏贴，留给自己做笔记。

ubuntu 16.04 安装Vivado 2016.3无法启动SDK，在相应SDK的安装目录下：Xilinx/SDK/2016.3/eclipse/lnx64.o/eclipse.ini中的-vmargs上面添加：
--launcher.GTK_version
2
实际eclipse.ini格式如下：
-startup
plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.300.v20150602-1417
-showsplash
com.xilinx.sdk.product
--launcher.GTK_version
2
-vmargs
-Xms64m
-Xmx512m

启动vivado，建立网口，内存，串口和cpu的最小系统导出hdf文件

之前遇到过petalinux-config 出了问题，各种怀疑，ERROR：提示发现找不到xsdb，source SDK目录的setting的shell，后没有改善，后来才发现，这个xsdb不是SDK的xsdb是petalinux16.04特有的附属安装的一个SDK，具体后续慢慢研究，总之在这个地方怀疑人生了好久，系统都重新安装了两次，这是个不好的习惯，也就是观察这个版本的petalinux的安装文件是9G多，15.4的才1G多，才去关注petalinux最后的安装提示，才怀疑是已经可以不用再source vivado 里面SDK的setting的shell了，而是只要source 这个多出来的arm专用的setting，再source petalinux的shell，两个都要source。

于是就有了流畅的以下的输出，很遗憾，这个地方之前出错的地方，自己晕头转向的时候，重装系统把临时笔记弄丢了，好可惜。

开始研究petalinux 16.4生成的镜像相关文件，先不着急这配置QSPI启动，去看看config和build的log文件。
