OTA field updates are a common requirement in modern embedded device deployments. The larger the amount of devices to control, the more important is having a good infrastructure that is reliable in updating and smart in rolling out the software.
Once the bootloader on your embedded device is up and running the development of kernel and userland in PTXdist-based BSPs is usually based on booting from network. Thus there is no need for the developer to write the boot media with a new image.
Before the ELC-E conference starts in Prague, Berlin hosts the All Systems Go conference, the successor of the systemd conference. In times of increasing IT security incidents with IoT devices, updating such systems in a secure and reliable way becomes more and more important. Michael Olbrich's talk outlines the challenges and possible solutions for a robust update process.
The autumn conference highlight is the Embedded Linux Conference Europe (ELC-E), which takes place in Prague this year. The Pengutronix team will be present with four talks and two demo points / showcases, presenting current open source projects (RAUC, labgrid, etnaviv).
