##同步poky源代码
git clone https://git.yoctoproject.org/git/poky
进入poky目录同步树莓派代码
git clone https://git.yoctoproject.org/git/meta-raspberrypi
##初始化环境
source oe-init-build-env raspberrypi
说明：指定目录raspberrypi
##编辑配置文件
vim ./conf/local.conf
将
MACHINE ??= "raspberrypi2"
注释
#PACKAGECONFIG_append_pn-qemu-native = " sdl"
#PACKAGECONFIG_append_pn-nativesdk-qemu = " sdl"
#ASSUME_PROVIDED += "libsdl-native"
文件末尾增加
GPU_MEN = “16”
说明：16为CPU核数
vim ./conf/bblayers.conf
修改成以下
BBLAYERS ?= " \
/home/gsta/liang/poky/meta \
/home/gsta/liang/poky/meta-yocto \
/home/gsta/liang/poky/meta-yocto-bsp \
/home/gsta/liang/poky/meta-raspberrypi \
"
##增加树莓派目录
BBLAYERS_NON_REMOVABLE ?= " \
/home/gsta/liang/poky/meta \
/home/gsta/liang/poky/meta-yocto \
"
##生成
bitbake rpi-basic-image
注意：同步过程很漫长，同步过程中一定要开启git代理和终端代理
整个同步下来大概有18G
##错误处理
bitbake complains if run as root
root@eb4b9143265d:/work/build-test01# bitbake -k core-image-sato
ERROR: OE-core's config sanity checker detected a potential misconfiguration.
Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
Following is the list of potential problems / advisories:
Do not use Bitbake as root.
ERROR: Execution of event handler 'check_sanity_eventhandler' failed
ERROR: Command execution failed: Exited with 1
Summary: There were 3 ERROR messages shown, returning a non-zero exit code.
