Hello all, I’m currently trying to build a Yocto build using WIC and integrating Mender. **tinker-board-s.con** ```auto require conf/machine/include/rk3288.inc KERNEL_DEVICETREE = "rk3288-tinker-s.dtb" UBOOT_MACHINE = "tinker-s-rk3288_defconfig" RK_BOOT_DEVICE ?= "mmcblk1" WKS_FILE ?= "tinker-board.wks" IMAGE_FSTYPES += "wic wic.bmap" WKS_FILE_DEPENDS ?= " \ mtools-native \ dosfstools-native \ virtual/bootloader \ virtual/kernel \ " IMAGE_BOOT_FILES ?= "\ ${KERNEL_IMAGETYPE} \ ${KERNEL_DEVICETREE} \ " ``` **rk3288-boot.wks** ```auto part loader1 --align 32 --size 4000K --ondisk ${RK_BOOT_DEVICE} --source rawcopy --sourceparams="file=idbloader.img" part reserved1 --align 4032 --size 64K --ondisk ${RK_BOOT_DEVICE} part reserved2 --align 4096 --size 4096K --ondisk ${RK_BOOT_DEVICE} part loader2 --align 8192 --size 4096K --ondisk ${RK_BOOT_DEVICE} --source rawcopy --sourceparams="file=u-boot.bin" part atf --align 12288 --size 4096K --ondisk ${RK_BOOT_DEVICE} part /boot --align 16384 --size=114688K --active --ondisk ${RK_BOOT_DEVICE} --source bootimg-partition --fstype=vfat --label boot --sourceparams="loader=u-boot" ``` **local.conf** ```auto MENDER_ARTIFACT_NAME = "TestDevice" INHERIT += "mender-full" DISTRO_FEATURES_append = " systemd" VIRTUAL-RUNTIME_init_manager = "systemd" DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit" VIRTUAL-RUNTIME_initscripts = "" MENDER_STORAGE_DEVICE = "/dev/mmcblk1" MENDER_STORAGE_DEVICE_BASE= "/dev/mmcblk1p" MENDER_STORAGE_TOTAL_SIZE_MB = "2048" # Use partition uuids rather than device and partition numbers MENDER_ENABLE_PARTUUID="n" # Partition used as the boot partition (match the wic /boot) MENDER_BOOT_PART="${MENDER_STORAGE_DEVICE_BASE}6" # Partition used as the first (A) rootfs partition. (create new root ?) MENDER_ROOTFS_PART_A="${MENDER_STORAGE_DEVICE_BASE}8" # Partition used as the first (B) rootfs partition.

IMAGE_BOOT_FILES = "zImage" # controls Mender features ...

(Normally yes) // Isn’t that in conflict with WIC creating this ?** **Second question: I’m running into the error here, any idea?** ```auto | DEBUG: Python function extend_recipe_sysroot finished [3916] DEBUG: Executing shell function do_image_wic [3917]INFO: Creating image(s)...

Mender does not work with the `wic` FSTYPE, I believe, although Mender also uses the wic tool. You need to use either the `sdimg` or `uefiimg` FSTYPE, depending on whether you are building with U-Boot or GRUB. More information about the basic build [here](https://docs.mender.io/system-updates-yocto-project/build-for-demo#configuring-the-build). If you need to customize the partitions, check out [`MENDER_EXTRA_PARTS`](https://docs.mender.io/system-updates-yocto-project/variables#mender_extra_parts).
