i used core-image-minimal for a raspberry pi 0w. But i get rfkill can not
open control device. when i give rfkill , i get the syntanx output, this
means it exists.
the wifi driver is installed.

What is the rfkill device? is it /dev/rfkill ?

Use

rfkill list

to list all devices. Then (for example):

rfkill unblock bluetooth
or
rfkill unblock all

to unblock the bluetooth device or all devices (resp.).

when i search for rfkill using an image that works
find / -name 'rfkill'

I get some files in /lib/ and other folders.
when i search with core-image-basic for rfkill, it does not exist.

how to add it ? is it a feature or sw package?

rfkill is part of Bluez5, you can add it to your image recipe.

Or:

https://git.yoctoproject.org/cgit.cgi/poky/plain/meta/recipes-connectivity/bluez5/

You should add it in .../conf/local.conf as:

IMAGE_INSTALL_append += "rfkill" (my best guess, easiest way).

My bad! :-(

Should read: IMAGE_INSTALL_append += "Bluez5"

Typo in the package name, no need to use += with _append, and missing
whitespace.  No, that won't work.

IMAGE_INSTALL_append = " bluez5"

I see.

This should be the another way, should'n it?

CORE_IMAGE_EXTRA_INSTALL += "bluez5"

Thank you,

If you're using core-image then that's the preferred way, yes.

this does not solve the issue so far.  It seems a package installed by
rpi-basic-image does the trick.

what is the difference between :

core-image-minimal
rpi-basic-image

I've never used meta-raspberrypi but you can just look at the image recipes
to find out.

The minimal bit of core-image-minimal isn't a joke, it boots but is missing
*lots* of functionality you might expect.
