wolfSSL is announcing wolfBoot support for the STM32N6 series added in PR #720, starting with the NUCLEO-N657X0-Q development board (STM32N657X0H). The STM32N6 is ST’s first Cortex-M55 microcontroller, designed for high-performance edge AI workloads with a dedicated Neural Processing Unit (NPU). wolfBoot provides cryptographic signature verification and secure firmware updates on this new platform. Getting started […]

wolfBoot Adds SD Card Secure Boot for Xilinx Zynq UltraScale+ MPSoC
wolfBoot now supports SD card boot on the AMD/Xilinx Zynq UltraScale+ MPSoC (PR #699). This brings authenticated, signature-verified boot of Linux directly from SD card partitions on the ZCU102 evaluation kit, complementing the existing QSPI flash boot path that has been the sole production boot option until now. The ZCU102 (quad-core Cortex-A53, dual Cortex-R5, FPGA […]
Read MoreMore TagwolfBoot 2.8.0 released
We are pleased to announce the release of wolfBoot 2.8.0, a major update that expands platform support, strengthens PSA and TrustZone integration, and delivers another round of meaningful hardening across the secure boot and firmware update flow. This release stands out for the breadth of hardware now supported. wolfBoot 2.8.0 adds or extends support for […]
Read MoreMore TagwolfBoot vs Intel Slim Bootloader
Since version 2.0.0, wolfBoot runs as a bare-metal bootloader on x86-64 (amd64 / Intel 64), using Intel FSP for silicon initialization — the same approach taken by Intel’s Slim Bootloader. So what sets them apart? Quite a lot. Getting started with wolfSSL? Download the latest libraries here and start exploring. Advanced Cryptography & Quantum Readiness […]
Read MoreMore TagwolfBoot adds DICE and Measured boot via PSA Initial Attestation
Secure boot establishes authenticity (“this image is signed by a trusted key”). But many modern deployments also need attestation: a portable, verifiable way to prove what actually booted to a relying party: during onboarding, after updates, and throughout a device’s lifetime. That’s where DICE (Device Identifier Composition Engine) comes in. DICE composes a device identity […]

ARMv8-M TrustZone (TrustZone-M) gives Cortex-M23, Cortex-M33, Cortex-M35P and related MCUs a clean, hardware-enforced way to split a system into two execution environments: Secure world: the hardware root of trust, key material, security services, and the code that configures isolation. Non-secure world: the main RTOS and application logic, kept away from secrets by hardware boundaries. In […]
Read MoreMore TagwolfBoot TrustZone-M Support on the Nordic nRF5340
We’re excited to announce that wolfBoot now delivers full TrustZone-M support for the Nordic nRF5340, one of the most popular dual-core SoCs in the connected IoT space. Beyond Basic Secure Boot The nRF5340’s application core features an Arm Cortex-M33 with TrustZone-M capabilities, and wolfBoot now takes full advantage of this architecture. By configuring the System […]
