I am working with IMX8M Mini EVK and yocto project build details:


Build Configuration:
BB_VERSION = "1.38.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "ubuntu-16.04"
TARGET_SYS = "aarch64-poky-linux"
MACHINE = "imx8mmevk"
DISTRO = "fsl-imx-xwayland"
DISTRO_VERSION = "4.14-sumo"
TUNE_FEATURES = "aarch64"


We have interfaced another SoC to iMX8MM EVK, the firmware binary will be loaded by iMX8MM to SoC.

the firmware.bin file i placed in the /lib/firmware/ directory.




After this i bitbake the distribution and it generated the sdcard image. i flashed the image and found that the firmware.bin file is not present in the /lib/firmware/


I think i need to do follow some extra procedure to add the firmware binary to /lib/firmware/.


Could you please point me to the proper steps or example any.


Thank you,
