Buildroot currently has all of the needed packages to use Mender as the primary update system. However, there isn't any documentation or examples now that provide a starting point for users. This lack of documentation makes setting up a Mender based update system difficult and time-consuming. Provided in this patch series is a mender_x86_64_efi_defconfig of which sets up an x86_64 EFI based build that is ready to flash to a USB pen drive or use in a QEMU environment. The system partition schema comprises of two equally sized root partitions and a data partition that mounts to /var/lib/mender as a persistent data store partition. There is a board/mender/readme.txt provided, which gives users documentation on how to flash the built image or boot the image using QEMU as well. The post-build and post-image-efi scripts also have four options: -a --artifact-name: - The name of the artifact, this is added to /etc/mender/artifact_info -o --data-part-size: - The data partition size. -d --device-type - The device-type used by mender to catagorize registered devices.

Mender UEFI PC sample config
|
|
=====================
|
|
|
|
1. Build
|
|
|
|
$ make mender_x86_64_efi_defconfig
|
|
|
|
Add any additional packages required. Update the files in board/mender/x86_64
|
|
and change /dev/vda to what is relevant for your platform: typically
|
|
/dev/mmcblk0p for eMMC and /dev/sda for USB or SATA.
|
|
|
|
$ make
|
|
|
|
2. Write the Pendrive
|
|
|
|
The build process will create a Pendrive image called disk.img in
|
|
output/images.
|
|
|
|
Write the image to a pendrive:
|
|
|
|
$ dd if=output/images/disk.img of=/dev/${pendrive}; sync
|
|
|
|
Once the process is complete, insert it into the target PC and boot.
|
|
|
|
Remember that if said PC has another boot device you might need to
|
|
select this alternative for it to boot.
|
|
|
|
You might need to disable Secure Boot from the setup as well.
|
|
|
|
3. Enjoy
|
|
|
|
Emulation in qemu
|
|
========================
|
|
|
|
Run the emulation with:
|
|
|
|
qemu-system-x86_64 \
|
|
-M pc \
|
|
-drive file=output/images/disk.img,if=virtio,format=raw \
|
|
-net nic,model=virtio \
|
|
-net user \
|
|
-serial stdio \
|
|
-bios </path/to/OVMF_CODE.fd>
|
|
|
|
Note that </path/to/OVMF.fd> needs to point to a valid x86_64 UEFI
|
|
firmware image for qemu. It may be provided by your distribution as an
|
|
edk2 or OVMF package, in a path such as /usr/share/edk2/ovmf/OVMF_CODE.fd.
|
|
|
|
Optional arguments:
|
|
- -enable-kvm to speed up qemu. This requires a loaded kvm module on the host
|
|
system.
|
|
- Add -smp N to emulate an SMP system with N CPUs.
|
|
|
|
The login prompt will appear in the serial window.
|
|
|
|
Tested with QEMU 4.1.1 on Fedora 31
|
|
|
|
Creating a mender-artifact
|
|
========================
|
|
|
|
The mender artifact is created in output/images/buildroot-x86_64-1.0.mender
|
|
|
|
You may wish to change --artifact-name=1.0 to a name that best suits your
|
|
particular needs, as this option changes the mender artifact name.
|
|
|
|
Using mender
|
|
========================
|
|
Please read the mender documentation at:
