wolfBoot, the secure bootloader from wolfSSL, has a new target: ST’s STM32G4 family of mixed-signal Cortex-M4F microcontrollers. The port has been validated on the NUCLEO-G491RE board (STM32G491RET6: 512 KB flash, 96 KB SRAM, 170 MHz). Why the STM32G4 The G4 family lands in a sweet spot for industrial and motor-control designs: enough FPU and DSP […]

wolfBoot adds support for the Xilinx Zynq-7000 (ZC702)
We are pleased to announce that wolfBoot now ships an upstream port for the AMD/Xilinx Zynq-7000 SoC, verified end-to-end on the ZC702 Evaluation Kit (XC7Z020). The port covers QSPI cold-boot, SD-card cold-boot, JTAG-loaded development, and signed Linux/U-Boot payload chain-loading. All of this comes from a single TARGET=zynq7000 build target. This rounds out wolfBoot’s Xilinx coverage. […]
Read MoreMore TagwolfBoot now support fTPM as Root of Trust in TrustZone
With wolfBoot 2.8.0, TrustZone became an increasingly important part of the platform’s security model. That release expanded wolfBoot’s ability to place cryptographic services inside secure TrustZone enclaves, including PKCS#11 support via wolfPKCS11, and PSA Crypto with DICE attestation through wolfPSA. In both cases, the benefit is clear: sensitive cryptographic operations and security-critical state can live […]

Ransomware now targets medical devices, not just IT systems. Once malicious code runs on a device, it can disrupt patient care. The best defense is preventing execution. wolfSSL blocks ransomware before it runs: wolfBoot – Prevents unauthorized firmware from executing at startup wolfCrypt – Encrypts storage and secures firmware updates to prevent tampering wolfSentry – […]
Read MoreMore TagWhy Secure Boot Is Now an FDA Expectation
The FDA now expects medical devices to use a secure boot. Without it, devices can run unauthorized firmware, including malware or compromised code from supply chain attacks. wolfBoot is a secure bootloader for embedded medical devices. It uses wolfCrypt to verify firmware signatures before allowing code to run. Only authenticated firmware executes. For additional security: […]
Read MoreMore TagA Second Helping of Security for the Raspberry Pi Pico
Last year, we wrote about the support we added for the Raspberry Pi Pico in wolfSSL. Since then, we haven’t been sitting idle. The wolf pack has been busy adding even more security goodness to the Pico ecosystem. If you thought TLS on a $1 microcontroller was impressive, wait until you see what we’ve been […]
