前言

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。

安装环境提醒

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。

安装过程踩坑记录

参考全志官方文档：https://d1.docs.allwinnertech.com/study/study_2getsdk/

1、安装软件包问题

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。

2、编译问题

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。

3、make过程中遇到的问题

问题一

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：

#gdbusmessage.c文件，路径为：./out/d1-nezha/compile_dir/target/host/glib-2.50.1/gio/gdbusmessage.c
gdbusmessage.c:2698:30:
      if (signature_str)
      tupled_signature_str = g_strdup_printf ("(%s)", signature_str);

#这个文件路径还请自行查找
dbusauth.c 1298
      if (line == NULL)
            goto out;
          debug_print ("SERVER: WaitingForBegin, read '%s'", line);

问题二

#### make failed to build some targets (1 seconds) ####

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。

问题三

strerror-sym.c:47:9: error: 'errnos_msgstr' undeclared (first use in this function)
  return errnos_msgstr + errnos_msgidx[idx];
         ^~~~~~~~~~~~~
strerror-sym.c:47:9: note: each undeclared identifier is reported only once for eac                                                                                                                        h function it appears in

  return errnos_msgstr + errnos_msgidx[idx];
                         ^~~~~~~~~~~~~
make[7]: *** [Makefile:946: gpg_error-strerror-sym.o] Error 1

通过查找文件定位
./out/d1-nezha/compile_dir/target/libgpg-error-1.27/src/errnos-sym.h 这个文件为空
编译不通过，相关变量没有定义
感谢全志官方群大佬的鼎力相助发了我一手头文件
这是缺少头文件中的内容

前言

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:

1. 设备始终接口时钟树

sys/kernel/debug/clk/clk_summary

2.引脚接口

sys/kernel/debug/pinctrl/pinctrl-maps

3.CPU外设用电情况

sys/kernel/debug/regulater/regulator_summary

4.中断控制器

proc/interrputs

5.内核loge打印

demesg

6.进程查看

top 查看cpu 内存使用情况
cpu_monitor 系统资源监控

7.带宽资源

mtop 抓取当前ddr带宽使用情况

8.二进制转换源码工具

add2line 可以转换当前二进制对应的源码位置

9.反汇编工具

objdump 可以直接将可执行程序反转为汇编

10.用户空间跟踪工具

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

BedRock

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

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?

BedRock

@tigger 好家伙，坐上平衡车也太秀了

BedRock

有的https://bbs.aw-ol.com/topic/102/ 查看这个帖，以及下面的评论哦

BedRock

这个编译链与跟文件系统编译链不匹配唉，重新制定下Tina的编译链试试？
我还是贴出来把：看文档：https://d1.docs.aw-ol.com/study/study_6helloword/

BedRock

如题，期待aw社区引入yocto构建

BedRock

已加入保修黑名单

BedRock

@qemuandroid 可以，但没有

BedRock

看一下文档中如何单独编译Kernel章节，你就知道了

BedRock

跟着佬，V853！！！

@wanglang 草草写一下

while true

dmesg -c > filename_<time>
sleep()

10次后，打包压缩一次

BedRock

@wanglang 一般用于debug的串口就是用来输出系统日志，不建议做他用。

内核日志写入SD卡，可以在应用层使用开机自启 shell脚本自己定期进行备份。

BedRock

你就当驱动不支持浮点！

BedRock

在Kernel目录中 make menuconfig

或者查看一下编译脚本，看看调用的是哪一个config文件：
文件路径在：linux-4.9/arch/arm64/configs
或者：linux-4.9/arch/arm/configs

或者从 build.sh 按照脚本流程走一下
