Preparations [Download here the starter archive] containing skeleton files + scripts. Extract it somewhere in a new directory (e.g., create rauc-lab). The code structure will become (mostly is, but some are TODO) as follows: rauc-lab/ ├── artifacts/ # <-- you'll create this │ ├── flash_spl.bin # A working flash.bin image you already have │ ├── flash_emmc.bin # Your new flash.bin (see tasks) │ ├── linux.itb # A kernel image (after removing the init… text/html 2025-08-07T20:54:29+03:00 http://ocw.cs.pub.ro/courses/ass/labs-2025/04/tasks/02?rev=1754589269&do=diff 02. Disk image & Debian You’ll be running scripts in ./scripts, either one by one or all together via ./run-all.sh. The scripts are templates — you may need to complete missing parts (search for TODOs)! 2.1. Install Debian into an empty directory Yes, really, you can easily do this! text/html 2025-08-07T15:35:10+03:00 http://ocw.cs.pub.ro/courses/ass/labs-2025/04/tasks/03?rev=1754570110&do=diff 03.

RAUC Finally, it comes down to installing RAUC into the Debian partitions. 📄 Our script: 15-install-rauc.sh is already complete. Feel free to read and understand it. This script will: * Mount both rootfsA and rootfsB * Uses QEMU and chroot to install: * rauc * your ca.cert.pem (certificate used to sign the update images) * system.conf * rauc-mark-good.service
