core-image-base installs = packagegroup-base-extended, whereas core-image-minimal doesn’t. packa= gegroup-base-extended adds things like kernel modules and other package groups that you’ll want for a more full-featured system.

Looks like you also need = to add ipv4 to the DISTRO_FEATURES:

 

DISTRO_FEATURES +=3D = "ipv4 wifi"

 

Might be worth trying.=

I'll test with it, but wh= y core-image-base vs. core-image-minimal?

I tried just adding DISTRO_FEATURES +=3D "wifi" to the local.= conf and bitbaking core-image-base, but I got a lot of errors:

NOTE: Resolving any missing task queue dependencies
ERROR: Nothing PROVIDES 'glibc'
ERROR: glibc was skipped: missing required distro feature 'ipv4' (not in DI= STRO_FEATURES)
ERROR: Required build target 'core-image-base' has no buildable providers.<= br> Missing or unbuildable dependency chain was: ['core-image-base', 'glibc']
So I got it working with core-image-minimal as I mentioned earlier just bef= ore your reply.
