一、开发环境搭建

众所周知，编译最让人头疼的就是主机环境问题！假设我手上有其他芯片厂商的板卡，每个厂商的SDK都使用不同的编译环境，而我的Ubuntu主机系统只有一个，那怎么办？

使用Docker容器！

按照Firefly官方维基介绍，推荐使用Ubuntu 18.04，那我们在Docker下搭建一个Ubuntu 18.04系统好了！

1.1 主机安装Docker

照搬我之前写的这篇：Linux工具篇 | Ubuntu搭建Docker容器引擎

1.2 Docker安装Ubuntu 18.04

$ sudo apt update$ docker pull ubuntu:18.04

切换Shell到Ubuntu 18.04：

$ docker container run -p 8000:3000 -it ubuntu:18.04 /bin/bashroot@32b7b9ddcaab:/# cat /etc/issueUbuntu 18.04.6 LTS \n \l

1.3 Ubuntu 18.04安装常用工具

root@32b7b9ddcaab:/# apt updateroot@32b7b9ddcaab:/# apt install byobu vim-gtk inetutils-ping net-tools wget cpio unzip rsync xz-utils

过程中需要配置地区，选择亚洲上海：

设置超级用户：

root@32b7b9ddcaab:/# apt install sudoroot@32b7b9ddcaab:/# visudo

添加自己的用户名，保存并退出：

neutionweiALL=(ALL:ALL) ALL

切换到普通用户：

root@32b7b9ddcaab:/# adduser neutionweiroot@32b7b9ddcaab:/# su neutionwei

二、下载Linux_SDK

进入Firefly官方进行下载，链接如下：

https://www.t-/doc/download/107.html

大家点击以下图片中指向的地方进行下载：

下载最新版本：

下载完成后首先使用md5sum进行校验：

$ lsmd5sum.txtREADME_EN.txtREADME.txtrk356x_linux_release_v1.2.0_1019_firefly_split.file0rk356x_linux_release_v1.2.0_1019_firefly_split.file1rk356x_linux_release_v1.2.0_1019_firefly_split.file2rk356x_linux_release_v1.2.0_1019_firefly_split.file3rk356x_linux_release_v1.2.0_1019_firefly_split.file4

$ md5sum *firefly_split*b633414d69240faa0c3bd755c255ede8 rk356x_linux_release_v1.2.0_1019_firefly_split.file05cb1e2b63bbb4e3595c731038f6723fd rk356x_linux_release_v1.2.0_1019_firefly_split.file1e06c0f29fd5a870e0942139a1877a470 rk356x_linux_release_v1.2.0_1019_firefly_split.file24e14fbf72ccbb9b87f81d83a256205b0 rk356x_linux_release_v1.2.0_1019_firefly_split.file3be8b003703b51e7220e52bb36439a357 rk356x_linux_release_v1.2.0_1019_firefly_split.file4

确认与目录内的md5sum.txt文件内容无误！

三、编译Linux_SDK

根据Firefly官方维基安装必要工具：

neutionwei@32b7b9ddcaab:/$ sudo apt-get install repo git ssh make gcc libssl-dev liblz4-tool \expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support \qemu-user-static live-build bison flex fakeroot cmake gcc-multilib g++-multilib \unzip device-tree-compiler python-pip ncurses-dev python-pyelftools

在Ubuntu 18.04新建一个目录：

neutionwei@32b7b9ddcaab:/$ cd ~neutionwei@32b7b9ddcaab:~$ mkdir projectneutionwei@32b7b9ddcaab:~$ cd project/neutionwei@32b7b9ddcaab:~/project$ pwd/home/neutionwei/project

主机使用docker命令把Linux_SDK拷贝到Docker下的Ubuntu 18.04：

$ docker cp rk356x_linux_release_v1.2.0_1019_split_dir 32b7b9ddcaab:/home/neutionwei/project

解压缩Linux_SDK：

neutionwei@32b7b9ddcaab:~/project$ cat rk356x_linux_release_v1.2.0_1019_split_dir/*firefly_split* | tar -xzv

配置板卡型号，选择roc-rk3568-pc-buildroot.mk：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ lsMakefile build.sh debian docs external mkfirmware.sh rkbin tools yoctoapp buildroot device envsetup.sh kernel prebuiltsrkflash.sh u-boot

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ ./build.sh roc-rk3568-pc-buildroot.mkprocessing option: roc-rk3568-pc-buildroot.mkswitching to board: /home/neutionwei/project/rk356x_linux_release_1019/device/rockchip/rk356x/roc-rk3568-pc-buildroot.mk

开始进行全编译：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ ./build.sh all

编译过程中发生的错误：

/bin/sh: 1: bc: not foundKbuild:42: recipe for target 'include/generated/timeconst.h' failedmake[1]: *** [include/generated/timeconst.h] Error 127Makefile:1244: recipe for target 'prepare0' failedmake: *** [prepare0] Error 2make: *** Waiting for unfinished jobs....HOSTCC scripts/recordmcountHOSTCC scripts/dtc/checks.oHOSTCC scripts/dtc/util.oLEXscripts/dtc/dtc-lexer.lex.cYACC scripts/dtc/dtc-parser.tab.hHOSTCC scripts/resource_toolHOSTCC scripts/mkkrnlimgHOSTCC scripts/mod/sumversion.oYACC scripts/dtc/dtc-parser.tab.cHOSTCC scripts/sortextableHOSTCC scripts/dtc/dtc-lexer.lex.oHOSTCC scripts/mod/file2alias.oHOSTCC scripts/asn1_compilerHOSTCC scripts/dtc/dtc-parser.tab.oHOSTCC scripts/extract-certHOSTLD scripts/mod/modpostHOSTLD scripts/dtc/dtcERROR: Running build_kernel failed!ERROR: exit code 2 from line 561:make ARCH=$RK_ARCH $RK_KERNEL_DTS.img -j$RK_JOBS

安装bc命令：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ sudo apt install bc

继续全编译：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ ./build.sh all

依然有错误：

./build.sh: line 874: /usr/bin/time: No such file or directoryERROR: Running build_recovery failed!ERROR: exit code 127 from line 874:/usr/bin/time -f "you take %E to build recovery" $COMMON_DIR/mk-ramdisk.sh recovery.img $RK_CFG_RECOVERY

安装time命令：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ sudo apt install time

继续全编译：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ ./build.sh all

过程中缺少什么命令就继续安装，然后继续全编译。Buildroot的编译过程比较漫长，因为涉及到源码包的抓取，而大部分源码包的网址不在国内，抓取速度慢，甚至出现错误！

四、打包Buildroot系统固件

更新打包目录软链接：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ ./mkfirmware.sh

打包Buildroot固件：

neutionwei@32b7b9ddcaab:~/project/rk356x_linux_release_1019$ ./build.sh updateimg

我们打包的固件在/home/neutionwei/project/rk356x_linux_release_1019/rockdev/pack/目录。

在主机使用docker命令把固件拷贝回主机烧写即可：

$ docker cp 32b7b9ddcaab:/home/neutionwei/project/rk356x_linux_release_1019/rockdev/pack/ROC-RK3568-PC-Buildroot-GPT-1231-2044.img .
