Bootloader Development

Firmware & Embedded

Secure boot, OTA updates, recovery mechanisms and production flashing solutions, building boot chains where every stage verifies the next and a failed update always falls back to a working image.

We delivered

Bootloader source with signing and key management scripts, an A/B update scheme with tested rollback paths, OTA client integration and update packaging pipeline, and a failure-mode test matrix.

Secure boot chains with signed images and hardware root of trust. A/B and recovery partition schemes with automatic rollback. OTA update clients and server-side update pipelines. Custom U-Boot and MCUboot ports and feature work.

Used for adding verified boot to a product before certification or launch, replacing a fragile update mechanism that has bricked field units, and factory provisioning lines that flash, key and test devices at scale.

Built with U-Boot, MCUboot, TF-A, OP-TEE, SWUpdate and HAB/AHAB.
