Yocto04-Camera

カメラモジュール旧式(OV5647)が購入

Yoctoの手順をおさらい。これからカメラを組み込む。
1. /home1/poky で source oe-init-build-env build_20171213
  /home1/poky/build_20171213 ができる
    build_20171213/conf ができる
    confの中にbblayers.conf,local.conf,templateconf.cfg ができる
2. local.conf 編集
  MACHINE ??= "qemux86"をコメントアウト
  以下を追加
  MACHINE = "raspberrypi0-wifi"
  DISTRO_FEATURES_append = " bluez5"
  COMBINED_FEATURES_append = " ext2 usbgadget usbhost wifi bluetooth"
  IMAGE_INSTALL_append = " linux-firmware-bcm43430 connman connman-client usbutils sudo local "
  IMAGE_FEATURES_append = " ssh-server-dropbear"
  # host setup
  hostname_pn-base-files = "yoctopi"
  INHERIT_append = " extrausers"
  EXTRA_USERS_PARAMS = "useradd -P XXXX pi;usermod -P XXXX root;"
  BB_NUMBER_THREADS = "8"
  PARALLEL_MAKE = "-j 8"
  DL_DIR ?= "/home1/work/poky/poky-downloads"
3. bblayers.conf 編集
  以下を追加
  /home1/poky/meta-openembedded/meta-oe \
  /home1/poky/meta-openembedded/meta-networking \
  /home1/poky/meta-openembedded/meta-perl \
  /home1/poky/meta-openembedded/meta-python \
  /home1/poky/meta-raspberrypi \
  /home1/poky/meta-local \
4. meta-local はすでにあるのでそのまま
5. build_20171213 でビルド bitbake rpi-hwup-image
