OMNECT_ADU_DEVICEPROPERTIES_COMPATIBILITY_ID

Used to configure compatibility between online updates. E.g. if you increase from 0 to 1 an online update via omnect portal is not possible. You have to reflash the device with the new image version containing OMNECT_ADU_DEVICEPROPERTIES_COMPATIBILITY_ID = "1".

OMNECT_BUILD_NUMBER

OMNECT_BUILD_NUMBER is appended to the upstream yocto version and thus part of DISTRO_VERSION.

OMNECT_DEVEL_TOOLS

List of tools which get installed into an omnect-os devel image.

OMNECT_FDT_LOAD_NAME

Name of u-boot device-tree bootscript to be generated for devices using u-boot as bootloader. Default is "fdt-load.scr".

OMNECT_FLASH_MODE_2_DIRECT_FLASHING

If value is 1 flash-mode-2 directly flashes the image. Default is unset. Normally we save the incoming image to RAM and verify it before we flash. On devices with a minimal RAM configuration this can fail. In this case you can skip the verifying and flash directly.

OMNECT_GRUBENV_FILE

Path to grubenv file in buildsystem. Defaults to ${LAYERDIR_omnect}/files/grubenv. Relevant for devices which use grub as bootloader, such as genericx86-64.

OMNECT_INITRAMFS_FSTYPE

In reference to INITRAMFS_FSTYPES the FSTYPE of our initramfs artefact. E.g. cpio.gz vs cpio.gz.u-boot.

OMNECT_KERNEL_SRC_URI

Variable appended to virtual/kernel recipes SRC_URI.

OMNECT_KERNEL_SRC_URI_LTE

Variable appended to virtual/kernel recipes SRC_URI in case 3g is in MACHINE_FEATURES.

OMNECT_PART_OFFSET_UBOOT_ENV1

Offset of the first u-boot environment in omnect-os-image. Machine specific configuration which is used in wic file to generate the omnect-os image and in u-boot + u-boot userspace tooling to access the u-boot environment. Note: Currently the redundant u-boot environment is part of the omnect-os-image. Note: This variable is used to create u-boot userspace runtime config files and the omnect-os-image. If you want to configure the u-boot env offset for u-boot, you have to set it in the appropriate u-boot redundant-env.cfg file, e.g. https://github.com/omnect/meta-omnect/blob/main/dynamic-layers/raspberrypi/recipes-bsp/u-boot/u-boot/redundant-env.cfg.

OMNECT_PART_OFFSET_UBOOT_ENV2

Offset of the second u-boot environment in omnect-os-image. Machine specific configuration which is used in wic file to generate the omnect-os image and in u-boot + u-boot userspace tooling to access the u-boot environment. Note: Currently the redundant u-boot environment is part of the omnect-os-image. Note: This variable is used to create u-boot userspace runtime config files and the omnect-os-image. If you want to configure the u-boot env offset for u-boot, you have to set it in the appropriate u-boot redundant-env.cfg file, e.g. https://github.com/omnect/meta-omnect/blob/main/dynamic-layers/raspberrypi/recipes-bsp/u-boot/u-boot/redundant-env.cfg.

OMNECT_PART_SIZE_BOOT

Size of boot partition. See partition layout.

OMNECT_PART_SIZE_CERT

Size of certificate partition. See partition layout.

OMNECT_PART_SIZE_DATA

Size of etc overlay parition. See partition layout.

OMNECT_PART_SIZE_FACTORY

Size of factory parition. See partition layout.

OMNECT_PART_SIZE_ROOTFS

Size of rootA resp. rootB parition. See partition layout.

OMNECT_PART_SIZE_UBOOT_ENV

Size of u-boot environment. Note: This variable is used to create u-boot userspace runtime config files and the omnect-os-image. If you want to configure the u-boot env size for u-boot, you have to set it in the appropriate u-boot redundant-env.cfg file, e.g. https://github.com/omnect/meta-omnect/blob/main/dynamic-layers/raspberrypi/recipes-bsp/u-boot/u-boot/redundant-env.cfg.

OMNECT_RELEASE_IMAGE

Boolean to reflect if a devel or a release image gets build. If set to OMNECT_RELEASE_IMAGE=1 no OMNECT_DEVEL_TOOLS get installed. Getty is disabled. U-boot and grub are configured to be non-interruptible and silent as possible. Kernel is silent on ttyS0. Local ssh access via omnect user is disabled.

OMNECT_UBOOT_WRITEABLE_ENV_FLAGS

Additional u-boot flags which have to be writable. See CONFIG_ENV_FLAGS_LIST_STATIC in upstream documentation.

OMNECT_USER_PASSWORD

Password of the omnect user. Default is "omnect".
