SWupdate ERROR: No suitable .swu image found

Question

I am rather new to eclipse hawkbit and SWupdate I have been trying to do a test implementation on a RPi before I go with the production implementation. I have Hawkbit up and running but I am having several problems with SWupdate, I have built a core-image-full-cmdline.wic and the .swu update Image along with it:

This is the local.conf :

MACHINE = "raspberrypi3"

IMAGE_FSTYPES += "wic"

RPI_USE_U_BOOT = "1"

KERNEL_IMAGETYPE = "uImage"

IMAGE_INSTALL_append = " kernel-image kernel-modules"

#WKS_FILES_raspberrypi3 = "ts-raspberrypi.wks"

PREFERRED_PROVIDER_u-boot-fw-utils = "libubootenv"

DISTRO_FEATURES_append = " systemd"

DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"

VIRTUAL-RUNTIME_init_manager = "systemd"

VIRTUAL-RUNTIME_initscripts = "systemd-compat-units"

ENABLE_UART = "1"

I also got this error when I changed the IMAGE_FSTYPE from ext4 rpimg to wic:

ERROR: update-image-1.0-r0 do_swuimage: swupdate cannot find image file: /home/aswin/yocto/build/tmp/deploy/images/raspberrypi3/core-image-full-cmdline.ext4.gz
ERROR: Logfile of failure stored in: /home/aswin/yocto/build/tmp/work/raspberrypi3-poky-linux-gnueabi/update-image/1.0-r0/temp/log.do_swuimage.87006
ERROR: Task (/home/aswin/yocto/layers/meta-swupdate-boards/recipes-extended/images/update-image.bb:do_swuimage) failed with exit code '1'

So I had to change the update-image.bb FSTYPE = ".wic"

And when I comment this out #WKS_FILES_raspberrypi3 = "ts-raspberrypi.wks" Then flash the image to a sd card and boot it nothing really shows up except for a blinking line. If I leave it, then the .swu file is way too big to upload it to hawkbit.

How do you expect it to work when you have HW compatibility errors, JSON file corrupted errors, forget about the hawkbit for now, and try to see if your sw-description file is creating the correct swu image file that updates the rootsfs or whatever you want to update using mongoose webserver and only then move on to the hawkbit.

First solve the errors that are coming before

suitable .swu image not found
