Web server

You The Ubuntu platform can update images via the web server for by itself or another platformother Ubuntu platforms.

SWUpdate web interface files

...

Therefore, you can update the images for it.

...

Buildroot 2024.02 - eMMC boot

When you run 'make config' to configure your build environment and after selecting the board, you will be prompted to choose a boot device. Refer to the picture below and Enter “1” to select eMMC.

...

After selecting eMMC size, you will be prompted to choose a root file system. Refer to the picture below and Enter “11” to select Buildroot 2024.02.

...

Buildroot Setup

After the completion of executing “make config”, enter the buildroot configuration by running the following command in the top directory of project.

Code Block
make bconfig

Select submenus for swupdate : Target packages → System tools. Select <*> for swupdate . Save the configuration and exit. Then execute “make” command to build the images.

...

Generate self-signed certificates

After updating the images to the platform and booting the system of it, it would fail to start SWUpdate daemon as shown below. It lacks a public key to activate the web server.

...

The procedure to generate self-signed certificates is the same as that in Ubuntu MATE 24.04 - eMMC boot. After generating the public key (mycert.cert.pem) by itself or coping it from other platforms which generate it, pack update.swu and will update the images for this Buildroot platform, add the parameter of SWUPDATE_ARGS=”-k /root/work/my_key/mycert.cert.pem -v” to /usr/lib/swupdate/conf.d/10-mongoose-args of the Buildroot platform and the web server will be activated successfully after reboot.

Web server

Besides adding the parameter (the path of the public key) to /usr/lib/swupdate/conf.d/10-mongoose-args for activating the web server, make sure the platform system clock is within the validity period of the public key (mycert.cert.pem) and reference the procedure of updating images by other Ubuntu platforms in Ubuntu MATE 24.04 - eMMC boot.

Yocto 4.2.4 - eMMC boot

When you run “make config” to configure your build environment and after selecting the board, you will be prompted to choose a boot device. Refer to the picture below and Enter “1” to select eMMC.

...

After selecting eMMC size, you will be prompted to choose a root file system. Refer to the picture below and Enter “12” to select Yocto 4.2.4.

...

After the execution of “make config”, you can modify linux\rootfs\initramfs\yocto\meta-swupdate\recipes-support\swupdate\swupdate\defconfig according to your requests. An example shown below enables systemd support、checks for hardware / software compatibility、uses environment in RAM as bootloader interface and enables verification of signed images … etc.
