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
