another one : build yocto for rpi

這次是 這一篇

git clone -b krogoth git://git.yoctoproject.org/poky
git clone -b krogoth git://git.openembedded.org/meta-openembedded
git clone -b krogoth git://git.yoctoproject.org/meta-raspberrypi

oe-init-env build之後，到 build/conf 下 修改 local.conf..
加上:

MACHINE = "raspberrypi3"
PREFERRED_VERSION_LINUX-raspberrypi = "4.%"
DISTRO_FEATURES_remove += "x11 wayland"
DISTRO_FEATURES_append += "systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"

bblayers.conf 修改成..

POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""


BBLAYERS ?= " \
  /home/charles-chang/rpi2016/sources/poky/meta \
  /home/charles-chang/rpi2016/sources/poky/meta-poky \
  /home/charles-chang/rpi2016/sources/poky/meta-yocto-bsp \
  /home/charles-chang/rpi2016/sources/meta-openembedded/meta-oe \
  /home/charles-chang/rpi2016/sources/meta-openembedded/meta-multimedia \
  /home/charles-chang/rpi2016/sources/meta-raspberrypi \
  "

BBLAYERS_NO_REMOVABLE ?= " \
  /home/charles-chang/rpi2016/sources/poky/meta \
  /home/charles-chang/rpi2016/sources/poky/meta-poky \
  "

然後 bitbake rpi-basic-image 就成工了。
build 完 dd , 可以開機。
但是 dtoverlay=pi3-disable-bt 沒作用。
uart 還是沒辦法當 console。只能用 hdmi + keyboard
