【armbian】国内编译提高速度

作者 stormwind

一、更新dockers配置文件Dockerfile

修改文件：lib/functions/host/docker.sh

修改内容：修改容器内pip国内源

二、配置代码分支分支

修改文件：./config/boards/orangepizero2w.csc

修改内容：

三、修改代码源

修改文件：lib/functions/configuration/main-config.sh

修改内容：

四、编译配置参数

./compile.sh build BOARD=orangepizero2w BRANCH=current BUILD_DESKTOP=no BUILD_MINIMAL=no KERNEL_CONFIGURE=yes RELEASE=jammy UBOOT_MIRROR=gitee  DOWNLOAD_MIRROR=china REGIONAL_MIRROR=china MAINLINE_MIRROR=bfsu GHCR_MIRROR=dockerproxy GITHUB_MIRROR=ghproxy

五、内核配置快捷方式

 [ It still works, but please prefer the new way. First, run './compile.sh BOARD=orangepizero2w BRANCH=current kernel-config'; then commit your changes; then build the image as normal. This workflow ensures consistent hashing results. ]

六、内核定制

./compile.sh BOARD=orangepizero2w BRANCH=current kernel-config

七、uboot定制

./compile.sh BOARD=orangepizero2w BRANCH=current uboot-config

【vscode】vue3+vscode+element

作者 stormwind

1、安装node

下载nodejs，当前最新版本是 node 16.8

国外下载地址：https://nodejs.org/en

国内下载地址：http://nodejs.cn/download

下载完成之后双击文件【node-v16.8.0-x64.msi】安装。nodejs全局环境变量配置参考 https://www.cnblogs.com/yyee/p/15209612.html

检查nodejs是否安装：

node -v

如果未安装nodejs，照下步骤安装：

2、设置镜像，提高npm安装软件的速度。

pnpm get registry

pnpm config set registry https://registry.npmmirror.com/

pnpm config set registry https://registry.npmjs.org/

pnpm get registry

3、安装pnpm

npm install -g pnpm -registry=https://registry.npmmirror.com/

4、查看端口占用

npm run dev –port 端口号

【lx2160】How to dynamically adjust MC log level using restool

作者 stormwind

Prerequisites: The board should be running Linux and connected to terminal console.

Note: For log level debug support, the restool version should be LSDK-2003-RC1 or above and MC version should be 10.20.0 or above.

To check restool version:

$ root@localhost:~# restool -v
restool LSDK-20.04

To check MC version:

root@localhost:~# restool -m
MC firmware version: 10.24.0

For debugging, use the ls-debug script available in the LSDK rootfs. There is no need to create the debug object.

ls-debug -h
-h, –helpls-debug help information
-ts, –timestamp=XEnable/Disable timestamp printing, X is ON or OFF
-c, –console=XEnable/Disable printing in UART console, X is ON or OFF
-l, –log=XEnable/Disable printing in DDR log, X is ON or OF
-u, –uart=XSet UART ID of the console, X = [0 – 4], 0 = OFF
-ll, –level=XSet logging level, X = [0 – 5]0: Global1: Debug2: Info3: Warning4: Error5: Critical
-m, mem, –memoryDump information about memory modules available
dpxy.zDump information about MC respective object

For example, to enable logging in console with log level INFO:

$ ls-debug --log=on --console=on --level=2              
dpdbg.0 created
DDR log printing ON
UART console printing ON
Log level set to 2
$ root@localhost:~# ls-debug --memory
Memory dumped information available in MC log/console
$ root@localhost:~# cat `find /dev/ -name "*mc_console"`

【安凯】环境搭建

作者 stormwind

一、配置gcc工具

export PATH="${PATH}:/opt/arm-anykav500-linux-uclibcgnueabi/bin"
临时生效，必须使用绝对路径。

二、libmpfr.so.4: cannot open shared object file: No such file or directory

sudo ln -s /usr/lib/x86_64-linux-gnu/libmpfr.so.6 /usr/lib/x86_64-linux-gnu/libmpfr.so.4

三、yylloc符号错误

……
186
187 extern YYSTYPE yylval;
188 //extern YYLTYPE yylloc;
189 int yyparse (void);
……
1193 /* The lookahead symbol. / 1194 int yychar; 1195 1196 / The semantic value of the lookahead symbol. / 1197 YYSTYPE yylval; 1198 / Location data for the lookahead symbol. / 1199 static YYLTYPE yylloc 1200 # if defined YYLTYPE_IS_TRIVIAL && YYLTYPE_IS_TRIVIAL 1201 = { 1, 1, 1, 1 } 1202 # endif 1203 ; 1204 / Number of syntax errors so far. */
1205 int yynerrs;
1206
……

调整yylloc为局部符号.

【安凯】SDK编译时./mkfs.jffs2打包失败问题

作者 stormwind

一、报错

./mkfs.jffs2: error while loading shared libraries: liblzo2.so.2: cannot open shared object file: No such file or directory

二、解决方法

sudo apt-get update              //更新源，可以先执行第二步，不能安装则尝试更新源
sudo apt-get install liblzo2-dev:i386

【dockers】提高下载速度的方法【dockers】

作者 stormwind 在

一、国内镜像

阿里云个人镜像（速度最快，下边是中科大的公共镜像，个人镜像的获取方法见本文最后）

https://ustc-edu-cn.mirror.aliyuncs.com

网易镜像

https://hub-mirror.c.163.com

百度镜像

https://mirror.baidubce.com

docker官方国内镜像

https://registry.docker-cn.com

 中科大镜像（不要用这个，现在已无法外网访问，仅限学校内网使用）

https://docker.mirrors.ustc.edu.cn

二、配置方法

修改/etc/docker/daemon.json（如果没有则新建此文件）

内容如下：

{
  "registry-mirrors": ["https://ustc-edu-cn.mirror.aliyuncs.com"]
}

也可以配置多个地址：

{
  "registry-mirrors": ["https://ustc-edu-cn.mirror.aliyuncs.com", 
                        "https://hub-mirror.c.163.com"
                      ]
}

三、验证

docker info

【dockers】给普通用户赋予docker权限

作者 stormwind

1、 查看当前用户组中是否有docker组

sudo cat /etc/group | grep docker

2、 如果没有则创建

sudo groupadd docker

3、 将用户加入docker组

sudo usermod -aG docker $USER
sudo usermod -aG dockerroot $USER

4、 退出用户重连即可

【NPM】run `npm fund` for details解决【NPM】

作者 stormwind

1、其实上面的提示也已经给出了解决或者排除问题的方法，那就是紧接着上面提示的下面，输入命令行:
npm fund
2、然后可以查看提示具体的提示内容，是依赖的打赏捐赠提示，然后再接着输入一行命令：
npm run dev
3、回车就可以了，一般都是开发者捐赠支持的提示，打开一个github的链接之后，会显示需要打赏捐赠的信息，此时如果不想捐赠或者跳过这个提示的话，直接在后面加–no-fund即可，具体命令如下：
npm install –no-fund
