极简 Yocto 项目所需的层/配置是什么

Question

I am using yocto to build the necessary images to boot my target (Renesas V3H). After cloning poky I cloned also the Renesas BSP layer . then I started the configuration:

source oe-init-build-env build
bitbake-layers add-layer ../meta-renesas

Then my build/conf/bblayers.conf looks like this:

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

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

BBLAYERS ?= " \
/home/user/Workspace/poky/meta \
/home/user/Workspace/poky/meta-poky \
/home/user/Workspace/poky/meta-yocto-bsp \
/home/user/Workspace/poky/meta-renesas \
"

My questions are:

• What are the required layers that should be built, I think for example meta-yocto-bsp is not required am I correct?
• What is the value to be given to the variable MACHINE can anyone give a hint how to search it?

Answer 1

If it is your own board, you will need your own layer with at least the MACHINE definition. If you are using an eval board from Renesas, you might find a suitable machine in the meta-renesas layer.

meta-yocto-bsp is sample BSPs for Beaglebone and other off the shelf boards, so you won't need it.
