STM32MP1 Distribution Package一些总结

1.必须的依赖包

PC $> sudo apt-get update
PC $> sudo apt-get install bison flex sed wget curl cvs subversion git-core coreutils unzip texi2html 
texinfo docbook-utils gawk python-pysqlite2 diffstat help2man make gcc build-essential g++ desktop-file-utils chrpath libxml2-utils xmlto docbook 
bsdmainutils iputils-ping cpio python-wand python-pycryptopp python-crypto
PC $> sudo apt-get install libsdl1.2-dev xterm corkscrew nfs-common nfs-kernel-server device-tree-compiler mercurial u-boot-tools libarchive-zip-perl
PC $> sudo apt-get install ncurses-dev bc linux-headers-generic gcc-multilib libncurses5-dev libncursesw5-dev lrzsz dos2unix lib32ncurses5 repo libssl-dev

2.repo 获取源码

#repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-20-06-24

repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-20-02-19

fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle
fatal: error [Errno 101] Network is unreachable
解决方法：先单独克隆repo

git clone https://gerrit-googlesource.lug.ustc.edu.cn/git-repo
mkdir .repo
mv git-repo/ repo
mv repo .repo
repo sync -c -j8

单独更新

repo sync --force-sync layers/meta-openembedded/
repo sync --force-sync layers/meta-openembedded/
repo sync --force-sync layers/meta-st/meta-st-openstlinux/
repo sync --force-sync layers/openembedded-core/
repo sync --force-sync layers/openembedded-core/bitbake/
repo sync

3. 源码获取完成，编译Distribution Package。

PC $> DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
PC $> bitbake st-image-wseton    //编译镜像PC $> bitbake st-image-weston  -c fetchall  //编译镜像

4.bitbake常用的一些命令

bitbake st-image-wseton -f //忽略某个包的错误，执行下去。可以减少编译等待时间。
bitbake st-image-wseton -c fetchall  //-C用于执行特定命令，这里fetchall.
bitbake -e linux-imx | grep ^SRC_URI=  //软件包下载地址
bitbake -s | grep linux      //查找所有包并显示包含有linux名字的包
bitbake -e linux-imx  | grep ^S=    //编译目录
bitbake linux-imx -C compile   //编译内核和dtb,-C的C是大写
bitbake opencv -c fetch
bitbake opencv -c clean

bitbake -k core-image-minimal
bitbake xx-image -c listtasks
bitbake -s | grep packagename
bitbake -e xxx-image | grep ^SRC_URI=
查看软件依赖
bitbake -g  packagename

bitbake -c clean -v u-boot
bitbake -c cleanall     xx-image            #清除所有编译中间
bitbake -c cleansstate   xx-image            #清除编译         
生成编译中的配置文件和类文件
bitbake -e > mybuild.log

bitbake -b 加上.bb文件的路径，即可以直接执行这个.bb文件
#查找包的原路径
bitbake -e linux-stm32mp | grep ^SRC_URI=
#查找包的bblayer
bitbake -e linux-stm32mp | grep ^S

5. bitbake 命令续

bitbake -e linux-stm32mp | grep ^S=
S="/home/fdw/32mp1/openstlinux-200219/build-openstlinuxweston-stm32mp1/tmp-glibc/work/stm32mp1-ostl-linux-gnueabi/linux-stm32mp/4.19-r0/linux-4.19.94"
bitbake -e m4projects-stm32mp1 | grep ^S=
S="/home/fdw/32mp1/openstlinux-200219/build-openstlinuxweston-stm32mp1/tmp-glibc/work/stm32mp1-ostl-linux-gnueabi/m4projects-stm32mp1/1.2.0-r0/git
