yocto sunxi machine name

Question

While running nanopi-neo image in yocto it throws the following error. In local.conf MACHINE ??= "nanopi-neo

ERROR: OE-core's config sanity checker detected a potential misconfiguration. Either fix the cause of this error or at your own risk disable the checker (see sanity.conf). Following is the list of potential problems / advisories:

MACHINE=nanopi-neo is invalid. Please set a valid MACHINE in your local.conf, environment or other configuration file.

Can anyone please tell me to fix this error?

Answer 1

Apparently, nanopi-neo is unknown target device for your setup. MACHINE ??= nanopi-neo looks as default value, so you most probably should set this variable to the target that is available in your bsp layer, which typically has name meta-bsp-smth. You can find the list of available devices in meta-bsp-smth/conf/machine folder (e.g. meta-bsp-smth/conf/machine/some_dev_name.conf). Then add to local.conf:

MACHINE ?= "some_dev_name"

Check also in conf/bblayers.conf which layers are enabled if error remains, that bsp layer's full path should be in the list of BBLAYERS.

Update

You can also check available products by running

# bitbake-layers show-products

and check the first column for availability and correct name of product. Then, available layers you can check by running:

# bitbake-layers show-layers

and check if meta-sunxi is in the output list.

Answer 2

you need to add meta-sunxi to your layermix.

git clone git://git.yoctoproject.org/poky
cd poky
git clone git://github.com/linux-sunxi/meta-sunxi
. ./oe-init-build-env
bitbake-layers add-layer ../meta-sunxi
MACHINE=nanopi-neo-air bitbake core-image-minimal

you can bitbake any image you like, if you want to not use MACHINE on cmdline it can be added to local.conf for persistence

MACHINE = "nanopi-neo-air"
