Infineon, Secured by Thistle

Keeping AI models up to date on edge devices can be complex, but ctuc (Thistle Update Client in C) and the Thistle Security Platform makes it effortless. Designed specifically for MCU firmware updates, ctuc enables seamless over-the-air (OTA) upgrades—including partial updates—so you can refresh AI models without a full firmware rewrite.

What typically takes senior firmware engineers 6–12 months to implement, ctuc simplifies with robust A/B update support and rollback capabilities, ensuring reliability even if something goes wrong. And with secure boot handled by the Board Support Package (BSP), your device remains protected every step of the way.
