iMX6 Yocto how to create fsl-image-gui with multiple partitions using 'wic'

Hi,

for our customized system we need to have a additional partition to store application data on SD-Card.

Tried to use 'wic' for this purpose, followed this thread:

Yocto WIC image creator with fixed partition sizes 

 

I can successfully build image for 'core-image-minimal' and 'fsl-image-gui' using 'bitbake'. I managed to create such SD-Card image for 'core-image-minimal' with following '.wks' file and command 'wic create imx6dl-ctems-2part.wks -e core-image-minimal'

 

# file name imx6dl-ctems-2part.wks

# Image Creator .wks
part u-boot --source rawcopy --sourceparams="file=u-boot.imx" --ondisk mmcblk --no-table --align 1

# Boot partition
part /boot --source bootimg-partition --ondisk mmcblk --fstype=vfat --label boot --active --align 4096 --size 8M --extra-space 0

# Rootfs partition
part / --source rootfs --ondisk mmcblk --fstype=ext4 --label root --align 4096 --size 256M --extra-space 0 --overhead-factor 1

# User data partition
part /opt/user --ondisk mmcblk --fstype=ext4 --label ctems --align 4096 --size 128M --extra-space 0 --overhead-factor 1

 

When I do this for 'fsl-image-gui' by command 'wic create imx6dl-ctems-2part.wks -e fsl-image-gui' I got the following error:

Checking basic build environment...
Done.

Linux target system is Kernel 4.1.15_2.0.0 (fsl release) on iMX6DL, build system Yocto 2.1 Krogoth running on Ubuntu 14.04.1 LTS 64 bit.

 

Any help would be appreciated?

Thanks Torsten
