All you need to do is to run the snapshot blow in an automated fashion, such as using the crontab. Using the snippet below, you can easily create automated backups. Since the drive can be running while you take the snapshot, combined with the fact that you only pay for the delta between the original disk and the snapshot, this becomes a very powerful backup tool. By inheriting the mender-full-ubi class in a Bitbake. For instance, in your nf: MENDERFEATURESENABLE:append ' mender-uboot'. 4. Spring Boot, ASP.NET MVC, etc) that reads/writes to a relational database schema. To utilize Mender's integration with U-Boot, when building with the Yocto Project you need to enable the mender-uboot feature using MENDERFEATURESENABLE. By modifying U-Boot source code, you can create your own built-in commands. One handy functionality in our API is the ability to take snapshots of a drive. U-Boot commands 4.1 Overview U-Boot has a set of built-in commands for booting the system, managing memory, and updating an embedded system’s firmware.

#DOKUMENTATION U BOOT CODE#
The code snippet below assumes that you have installed your SSH key into the server's meta data with the key 'ssh_public_key'. That's great, but what if we want to put this to use? Don't worry, we got you covered. Unlike many other distributions for routers, OpenWrt is built from the ground up to be a full-featured, easily modifiable operating system for embedded devices. In the example above, we pushed an SSH key as meta data to a server. Documentation Documentation OpenWrt is a highly extensible GNU/Linux distribution for embedded devices (typically wireless routers).
#DOKUMENTATION U BOOT HOW TO#
Please note that you will need to logout and log in again for the permission change to take effect.įor more examples on how to read and write meta data, please visit our API documentation. Hence you need to either change the permission, or add your user to the group sudo usermod -a -G dialout $(whoami). For instance, on Ubuntu, the default owner is root and the group is set to dialout. If you get a permission error while running the above command, make sure you have access to read from /dev/ttyS1. get()įrom pprint import pprint pprint( metadata)
