🚀 Ensuring reliable OTA updates for embedded Linux systems

Forlinx Embedded shares a detailed guide on implementing Over-the-Air (OTA) firmware upgrades using RAUC (Robust Auto-Update Controller) on the OKMX8MM platform (NXP i.MX8M Mini) running Linux 4.14.

🔧 Key highlights:

✅ Secure and robust update mechanism for industrial applications

✅ Dual-slot A/B update strategy to ensure rollback safety

✅ Integration with systemd, U-Boot, and RAUC configuration examples

✅ Practical verification steps for real-world deployment

🚀 Seamless OTA Upgrades for Forlinx OKMX8MP-C

We’ve implemented a robust OTA upgrade process for the Forlinx Embedded OKMX8MP-C development board running Linux 5.4.70. Using RAUC, our approach ensures:

Lossless upgrades: Dual-system partitions prevent downtime during updates.

Flexible deployment: Upgrade packages can be applied via network, SD card, or USB.

Rollback capability: If an update fails, the system safely reverts to the previous version.

Highlights include: ✅ Environment setup with Ubuntu 22.04 and GCC 7.x ✅ Partition and rootfs configuration for A/B system upgrade ✅ RAUC-based bundle creation and deployment ✅ Safe system upgrade and boot partition switching
