Hi,

 

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"
TARGET_FPU = ""

 

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.

 

imx-yocto-bsp/Build-xwayland-imx8mmevk/tmp/work/imx8mmevk-poky-linux/fsl-image-validation-imx/1.0-r0/rootfs/lib/firmware/

 

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,

Sreedhar
