Creating Yocto Mender for Raspberrypi 3

I need help creating Mender for Raspberry Pi3. I can create the image, but when using Win32Image to burn the Disk Image it doesn't boot.

Here is my additional conf.log 

MENDER_ARTIFACT_NAME = "release-1"
INHERIT += "mender-full"
MACHINE ?= "raspberrypi3"
RPI_USE_U_BOOT = "1"
MENDER_PARTITION_ALIGNMENT_KB = "4096"
MENDER_BOOT_PART_SIZE_MB = "40"
IMAGE_INSTALL_append = " kernel-image kernel-devicetree"
IMAGE_FSTYPES_remove += " rpi-sdimg"
DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
VIRTUAL-RUNTIME_initscripts = ""
IMAGE_FSTYPES = "ext4"

and bblayers

POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
  /home/ubuntu/pyro/poky/meta \
  /home/ubuntu/pyro/poky/meta-poky \
  /home/ubuntu/pyro/poky/meta-yocto-bsp \

  "

I can create the rpi-basic image as follows:

Maybe I am missing some steps?

Solution

  • The pyro branch of meta-raspberrypi does not support the RPI_USE_U_BOOT setting. For that (and older) branches you need to use 'KERNEL_IMAGETYPE_rpi = "uImage"' instead.
