rk356x 关于yocto编译linux及bitbake实用方法

Yocto 完整编译

  source oe-init-build-env
  bitbake core-image-minimal

Yocto 查询包名

bitbake -s | grep XXX
// 获取rockchip相关包
:~/rk3568/yocto$ bitbake -s | grep rockchip
android-tools-conf-rockchip                           :1.0-r0

Yocto 确定包的源码目录

// 从包名确认内核名为linux-rockchip    
:~/rk3568/yocto$ bitbake -e linux-rockchip  | grep ^S=
S="/homexx/yocto/rk3568/yocto/build/tmp/work-shared/roc-rk3568-pc/kernel-source"

Yocto 确定包的下载地址

:~/rk3568/yocto$ bitbake -e linux-rockchip | grep ^SRC_URI=
