yocto开机动画:

cmdline: psplash=false

./make-image-header.sh base-images/xc9031.png POKY
cp xc9031-img.h ../psplash-poky-img.h
bitbake  -C compile psplash

cmdline中bootargs psplash=${psplash}'

Yocto Toaster:

sudo pip install -r poky/bitbake/toaster-requirements.txt
source toaster start

相关问题

fetch耗时

fetch一些大的软件包，很费时，半天都下不下来：

  1. 确定下载的地址，手动git下载
    bitbake -e XXX | grep ^ SRC_URI（或者直接在source里面查找对应的bb文件）
  2. 修改对应的bb文件
    主要是SRC_URI = "git:///home/jack/yocto/downloads/opencv;protocol=file;branch=2.4 \，注意protocol指定
  3. 从本地repo中checkout对应的branch 
    git branch -a
git checkout origin/2.4 -b 2.4
  4. 再次获取
    bitbake XXX -c fetch
