I want to do OTA (Over The Air) updates in my Raspberry Pi. I have seen a lot of services on the internet like mender.io, but they are all quite expensive. Is there any easy/less expensive way to do OTA updates in my RPI? For example, I have 2 partitons in my RPI. In one partition my current OS is running, and now I download the updated OS and would like to install it on 2nd partition. If the installation gets completed without any problem then the bootloader will boot from this partition next time.

Can somebody guide me how can this be achievable?

  • This would be a feature of the operating system itself. Since most or all of the linux distros commonly used on the Pi have it intrinsically (eg. on Raspbian apt update; apt upgrade), it's not clear what you are looking for...

    Again, the idea of OTA updates that store a full copy of a firmware in a partition and then boot from that is for cases where the device only runs one piece of code (microcontroller). For two reasons. 1) it cant update its code while running. 2) it needs to be able to fall back in the event of an incomplete download or corrupt data. Again this is all handled by apt-get and other package managers so just go ahead and automate them.

    That's part of what the package manager does. It's certainly not perfect, but you don't really think it is just plain dumb do you? That stuff has been around for 20 years and is used in probably the broadest context that any software could be, meaning, apt has been deployed everywhere for a long time. You should try to learn about that first, before you assume it doesn't cover most of what you want. After that, you should investigate automated configuration managers such as chef or puppet, and conventional, efficient methods of incremental backup such as rsync...

    Hawkbit + rauc (or) swupdate might be a solution

Use Hawkbit as a deploy server.

And rauc (or) swupdate as a client on RaspberryPi side.
