Hi João,
I'm having some trouble creating an image, looks like the assignment to
krootfs_dir['ROOTFS_DIR'] is bogus?:
[trz@empanada build]$ wic create directdisk-multi -e core-image-minimal
Checking basic build environment...
Done.
Creating image(s)...
Traceback (most recent call last):
File "/home/trz/yocto/master-cur/scripts/wic", line 252, in <module>
ret = main()

krootfs_dir['ROOTFS_DIR'] = rootfs_dir
TypeError: 'NoneType' object does not support item assignment
My directdisk-multi.wks contains this:
part /boot --source bootimg-pcbios --ondisk sda --fstype=msdos --label boot
--active --align 1024
part / --source rootfs --ondisk sda --fstype=ext3 --label platform --align 1024
part /standby --source rootfs
--rootfs-dir=/home/trz/yocto/master-cur/build/tmp/work/crownbay-poky-linux/core-image-minimal/1.0-r0/rootfs/
--ondisk sda --fstype=ext3 --label secondary --align 1024
bootloader --timeout=0 --append="rootwait rootfstype=ext3 video=vesafb
vga=0x318 console=tty0"
