vscode的跳转需要C/C++扩展开启 IntelliSense 功能，该功能会根据工程进行深度的函数及变量的搜索，将其存储为索引文件，存储在内存中。
！所以：Vscode的跳转要流畅需要占用比较大的运行内存空间。你可以尝试使用 资源管理器查看一下 进程的资源占用情况。
它还带有代码提示功能。
内存不够的兄弟 可以转 隔壁 Source Insight 来实现对应功能。
关于其配置，你可以在网上找到大多例程，同时你可以参考：扩展中的参考配置来进行你工作空间的配置。
总的来说，适合自己的才是最好的，如果你愿意折腾，愿意自己调教自己的开发环境，愿意在这上面花时间，你还是会收获一个自己满意的开发环境的
本人使用Ubuntu21.04，是在Ubuntu18.04 使用系统升级的方法升级，并非直接安装Ubuntu21.04 系统镜像。希望参考该帖开发者注意。
再Ubuntu更新软件包同时，个人不推荐使用清华源，可能会出现一些软件包安装找不到的问题（因为我之前就是），后面改为阿里源，然后就没有出现过软件包依赖的相关问题。切换软件源请自行百度参考帖子。
参考全志官方文档：https://d1.docs.allwinnertech.com/study/study_2getsdk/
sudo apt-get install build-essential subversion git-core libncurses5-dev zlib1g-dev gawk flex quilt libssl-dev xsltproc libxml-parser-perl mercurial bzr ecj cvs unzip lib32z1 lib32z1-dev lib32stdc++6 libstdc++6 -y
在软件包安装的时候 建议取消后面 -y 选项 ,先看一下有没有自动卸载一些包 如果有建议取消安装，然后一个一个包安装。
如果出现软件包找不到的情况，请自行使用Tab补齐命令查看可以安装的包，并选择何时的包进行安装。
针对于32位的软件包
sudo apt-get install libc6:i386 libstdc++6:i386 lib32ncurses5 lib32z1
更有可能出现找不到的情况，依然使用Tab补齐命令，查看当前可以安装的包，并选择何时的包进行安装。
依然参考官方文档：https://d1.docs.allwinnertech.com/study/study_4compile/
source 环境变量如果有错，请检查文件夹权限，将文件夹权限由root用户更改为普通用户。
如果还有问题，请根据具体信息对照 envsetup.sh文件中的 envsetup函数。一一落实执行过程。
报错提示没有记录，查看报错提示，可以定位到 两处文件，修改其源码为：

这个主要是文件夹及文件权限问题，给这几个文件及它的文件夹777权限。
基本是 tmp文件夹的相关属性。

The D1 Nehza and noticedthat despite the Nehza having connectors that appear identical to the Raspberry Pi, they actually are not 100% compatible.
The GPIO header is mostly compatible. Some of the higher numbered pins are listed in the datasheet as NC, meaning that some GPIOI are lacking. Furthermore, some of the secondary peripheral functions seem different.
The Display ribbon cable connector is not physically compatible. It is still a MIPI-DSI connection, but the pinout is different. A adapter will be needed to use it with the Raspberry Pi Display.
The "Camera" ribbon cable connector is not compatible at all. On the Nehza it is not actually a camera connector, but instead analog and digital connections for a microphone breakout board. There is no MIPI-CSI capability on the connector (from what I can tell, the only MIPI-CSI connection shares pins with the RGMII connection, which is used for ethernet)
The 3.5mm audio jack is not entirely compatible. There is not an analog video out connection, instead there is a microphone input.
Be sure to check the schematics (I found them on the linux-sunix wiki), before trying to use any Raspberry Pi cessories to be sure you will not break anything.

哪吒D1开发板虽然多数引脚及外设接口看起来与树莓派相同，但使用的过程中仍然有需要注意的与树莓派不兼容的地方。
在使用树莓派的模块之前，一定要对照原理图检查确保其可用引脚相互不冲突，与功能正常，以保不会烧毁任何模块。
我们做开发的过程中难免会遇到各种各样问题,Windows中有强大的调试工具和软件仿真软件等等..Linux中的调试工具却有着举足轻重的地位,和更为丰富的功能.下面我们一一展开:
sys/kernel/debug/clk/clk_summary
sys/kernel/debug/pinctrl/pinctrl-maps
sys/kernel/debug/regulater/regulator_summary
proc/interrputs
demesg
top 查看cpu 内存使用情况
cpu_monitor 系统资源监控
mtop 抓取当前ddr带宽使用情况
add2line 可以转换当前二进制对应的源码位置
objdump 可以直接将可执行程序反转为汇编
starce 可以查看当前进程空间的跟踪,什么进程在干什么,占了多少资源.
ioctr占了多少带宽,执行消耗了多少资源.
当然还有很多很多其他的工具,有需要的时候再看
之前已经知道使用 平头哥的新版编译器在编译文件的时候在哪吒上跑会出现 GLIBC_2.29 not define 的错误.
此处借鉴 nihui 在编译 ncnn 时的写法~加上
-static #全部链接成静态
就能在Tina中运行啦.
根据"有限的情报"新版编译器应该比旧的编译器优化的情况好一些.但是看运行情况发现,新版的编译链在哪吒上的执行效率更低 是怎么回事呢?
有的https://bbs.aw-ol.com/topic/102/ 查看这个帖，以及下面的评论哦
@astonzorro 最简单的方法： 交叉编译链的 -l 链接动态库 -i 包含头文件路径 参数来设置
高级方法：包管理
工具方法：cmake（教程很多）
