local.conf,

# Add FIT image dependency
KERNEL_CLASSES += "kernel-fitimage"
KERNEL_IMAGETYPES += "fitImage"

# Specify FIT image variables
UBOOT_ENTRYPOINT = "0x47800000"
UBOOT_LOADADDRESS = "0x47800000"

INITRAMFS_IMAGE = "core-image-base"
INITRAMFS_IMAGE_BUNDLE = "1"

Please check the local.conf file for fitImage

Hi Vinothkumar

one can refer to uboot guides for generation FIT images:

https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4/guides/mx8m_secure_boot.txt?...

https://source.codeaurora.org/external/imx/uboot-imx/tree/doc/imx/habv4/csf_examples/mx8m?h=imx_v202...

Best regards

Thank you @igorpadykov  for the reply,

Actually I am looking for kernel-fit (Kernel, DTB, Initramfs) Image like this,

local.conf,

# Add FIT image dependency
KERNEL_CLASSES += "kernel-fitimage"
KERNEL_IMAGETYPES += "fitImage"

# Specify FIT image variables
UBOOT_ENTRYPOINT = "0x47800000"
UBOOT_LOADADDRESS = "0x47800000"

INITRAMFS_IMAGE = "core-image-base"
INITRAMFS_IMAGE_BUNDLE = "1"
IMAGE_FSTYPES = "cpio.gz"

Please check the local.conf file for kernel-fitImage

Will you please tell what return -3 

-5 = is image is too large

but, what is -3 returns,

Error: inflate() returned -3

This is due to load address issue.
