ok thanks for the hint. I read the wic part in the dev-manual of yocto

 https://www.yoctoproject.org/docs/1.5.2/dev-manual/dev-manual.html

after that I tried to write my own imx-test.wks for wic.

# short-description: Create SD card image with a boot partition and two rootfs
# long-description:
# Create an image that can be written onto a SD card using dd for use
# with i.MX SoC family
# It uses u-boot
#
# The disk layout used is:
#  - --------- --------- ------------ ------------ -----------
# | | u-boot  |  /boot  |  rootfs 1  |  rootfs 2  |   data   |
#  - --------- --------- ------------ ------------ -----------
# ^ ^         ^         ^              ^
# | |         |         |              |
# 0 1kiB    4MiB   4MiB + 8MiB    4MiB + 8Mib + rootfs 1 + rootfs 2 + data  IMAGE_EXTRA_SPACE (default 10MiB)
#
part u-boot --source rawcopy --sourceparams="file=u-boot.img" --ondisk mmcblk --no-table --align 1
part /boot --source bootimg-partition --ondisk mmcblk --fstype=vfat --label boot --active --align 4096 --size 8M --extra-space 0
part / --source rootfs --rootfs-dir=rootfs1 --ondisk mmcblk --fstype=ext4 --label platform --align 4096
part /rescue --source rootfs --rootfs-dir=rootfs2 --ondisk mmcblk --fstype=ext4 --label secondary --align 4096

I also added to my build-imx6ulevk/conf/local.conf

IMAGE_BOOT_FILES = "u-boot.img zImage:kernel"

then I execute:

wic create imx-test.wks -e fsl-image

and get the follwing output:


Done.
Creating image(s)...

Couldn't get 'bitbake -e rootfs1' output.
Bitbake failed with error:

Where do I need to provide rootfs1 and rootfs2. Can you comment my first try :)
