Hi NXP support,
We follow the procedure of “i.MX_Yocto_Project_User's_Guide.pdf” to build image, but the built rootfs image is too large.
Our image limit is 32MB, How to build smaller rootfs image that can support WIFI/Bluetooth
Solved! Go to Solution.

Try to build the core-image-minimal. This image contains only a minimum set of applications. If you want to add more applications to it create your own image recipe. The skeleton should look like this:
require recipes-core/images/core-image-minimal.bb
IMAGE_INSTALL += "nano"- Mark as New

Hi support,
it is typo,
it should be "CORE_IMAGE_EXTRA_INSTALL += "packagegroup-base-bluetooth packagegroup-base-wifi""

Hi Robert,
I add "CORE_IMAGE_EXTRA_INSTALL += "packagegroup-base-bluetooth packagegroup-core-wifi"" in core-image-minimal.bb.
I can find the bluetooth in image, but don't find any libraries about wifi in image like following.
./lib/firmware/bcm/ZP_BCM4339/bcmdhd.ZP.SDIO.cal
./lib/firmware/bcm/ZP_BCM4339/bcmdhd.ZP.OOB.cal
