ubuntu2004的chroot环境
工作需要ubuntu2004的chroot开发环境，故这里记录搭建ubuntu2004的chroot环境。
镜像地址
如下：
获取环境
mkdir iso && mount ubuntu-20.04.6-desktop-amd64.iso iso/ unsquashfs iso/casper/filesystem.squashfs umount iso && rm -rf iso
准备chroot
为了能够chroot的一些编译工作正常，更真实的模拟实际环境，这里需要和linux启动一致，挂载必要的文件系统如下：
vim 1-chroot #!/bin/bash CHROOT_DIR=/root/sdk/chroot/squashfs-root [ ! -d ${CHROOT_DIR} ] && exit cd ${CHROOT_DIR} mountpoint -q ./proc || mount -t proc proc ./proc mountpoint -q ./sys || mount -t sysfs sysfs ./sys mountpoint -q ./dev || mount -t devtmpfs devtmpfs ./dev mountpoint -q ./dev/pts || mount -t devpts devpts ./dev/pts chroot .
为了能够全局使用，可以放在/usr/local/sbin/下面
mv 1-chroot /usr/local/sbin/
到这里，chroot环境已经基本成型，下面需要针对这个chroot环境做一些易用的改动。
配置源
配置源之前先设置dns，这里是chroot环境，所以直接修改resolv.conf文件，这里以114为例
nameserver 114.114.114.114
然后修改源地址为国内，修改文件/etc/apt/sources.list如下
deb http://mirrors.aliyun.com/ubuntu/ focal main restricted deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted deb http://mirrors.aliyun.com/ubuntu/ focal universe deb http://mirrors.aliyun.com/ubuntu/ focal-updates universe deb http://mirrors.aliyun.com/ubuntu/ focal multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted deb http://mirrors.aliyun.com/ubuntu/ focal-security universe deb http://mirrors.aliyun.com/ubuntu/ focal-security multiverse
最后update一下即可
禁止一些低级操作
为了避免reboot和一些低级操作，这里需要处理一下（在特殊情况下会生效），故如下
vim /etc/profile.d/chroot.sh hint_reboot(){ info="Forbidden reboot!" echo -e "\033[31m${info}\033[0m" } hint_poweroff(){ info="Forbidden poweroff!" echo -e "\033[31m${info}\033[0m" } hint_halt(){ info="Forbidden halt!" echo -e "\033[31m${info}\033[0m" } alias reboot='hint_reboot' alias poweroff='hint_poweroff' alias halt='hint_halt'
提示chroot
为了提示自己是在chroot环境中，修改bashrc如下：
vim /root/.bashrc # 1.修改TERM为xterm-color TERM=xterm-color cd source /etc/profile.d/chroot.sh # 2.修改\h为chroot 54 if [ "$color_prompt" = yes ]; then 55 # PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' 56 PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@chroot\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ ' 57 else 58 PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' 59 fi ......

打包
umount dev/pts dev proc sysfs && cd ..
tar cvzf ubuntu-2004-develop.tar.gz squashfs-root/
至此获得ubuntu-2004-develop.tar.gz是可用于x86的ubuntu2004的chroot
导入docker
docker import ubuntu-2004-develop.tar.gz x86-ubuntu2004-dev:v1
这样docker内也能正常使用此环境
RK3588S开发板编译
自己购买了RK3588S的firefly的开发板，这里记录firefly板子的sdk编译方法。
Wiki地址
https://wiki.t-firefly.com/zh_CN/ROC-RK3588S-PC/linux_compile.html#huo-qu-sdk
仓库地址
firefly的gitlab仓库地址如下
拉取SDK
repo init --no-clone-bundle --repo-url https://gitlab.com/firefly-linux/git-repo.git -u https://gitlab.com/firefly-linux/manifests.git -b master -m rk3588_linux_release.xml
这里拉取在我的环境会报错，主要如下
- DeprecationWarning: the imp module is deprecated 这里好像是和python3不支持import imp模块，如果默认是python3的情况下，则需要修改为
import importlib
-
str object has no attribute decode 然后继续运行，会出现如上错误，这里错误是没办法decode，
根据百度搜索可知，去掉git_config.py内的decode函数即可。 -
firefly的repo推荐使用python2 通过提示可知道，repo推荐你去使用python2，这里修改python为python2即可
ln -sf /usr/bin/python2 /usr/bin/python
同步代码
跟着文档走，直接如下命令同步即可
.repo/repo/repo sync -c --no-tags
.repo/repo/repo start firefly --all
后续可以使用以下命令更新 SDK:
.repo/repo/repo sync -c --no-tags
切换分支
这里默认分支用tag: rk3588/linux_release_v1.1.1d。需要主动切一下
编译uboot
注意uboot的make.sh，这里如果默认的CROSS_COMPILSE_ARM64变量有问题需要根据实际情况修改，如果没问题就无需修改 注意：编译uboot需要rkbin仓库，如没有rkbin仓库，则编译会因为无法编译miniloader而失败
-CROSS_COMPILE_ARM64=../prebuilts/gcc/linux-x86/aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- +# CROSS_COMPILE_ARM64=../prebuilts/gcc/linux-x86/aarch64/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- +CROSS_COMPILE_ARM64=YOUR_PATH/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
编译命令如下
make rk3588_defconfig firefly-linux.config && ./make.sh
编译完成之后，会生成如下文件
uboot.img rk3588_spl_loader_v1.11.112.bin
修改
uboot通常不打开pcie的phy识别usb3.0，这里默认打开即可

firefly的日志比较烦人，可以去掉

编译内核
编译内核主要选择好了设备树和配置即可，rk3588s-roc-ps-v1.0的配置如下
export ARCH=arm64 export CROSS_COMPILE=aarch64-linux-gnu- make rockchip_linux_defconfig rk3588_linux.config firefly-linux.config make roc-rk3588s-pc-mipi101-M101014-BE45-A1.img -j8
值得注意的是，我的开发板并不需要mipi dsi显示和csi摄像头，所以设备树需要更换一下。
