While working on wolfBoot, many people ask us, how is it different from u-boot, and how does it compare to it if I am designing a secure boot strategy for my embedded systems based on microprocessors. While taking the same role in embedded systems, wolfBoot and u-boot are two very different projects. As bootloaders, they […]

wolfBoot: secure boot and more | Unique features to assist and optimize firmware updates
Secure boot. Simple, compact, safe. wolfBoot is the universal secure bootloader designed for embedded systems. Its main task is to ensure that only a trusted firmware image can run on the target device, as indicated by RFC9019. To do so, it uses signature verification on the firmware image every time the device starts or when […]
Read MoreMore TagwolfBoot support for the Xilinx Zynq UltraScale+ MPSoC
wolfBoot support for the Xilinx UltraScale+ was added in 2020 and is a direct U-Boot replacement for improved security. wolfBoot provides enhanced features compared to U-Boot such as: Firmware integrity and signature verification on each boot Image integrity checking SHA2-256 or SHA3-384. Validation of the signature using ECC P256/P384, RSA (2048-bit or 3072-bit), ED25519 and […]
Read MoreMore TagwolfBoot support for the STM32C0 in 2024
We have added wolfBoot support for the new STM32C0. This is a low cost MCU similar to the STM32G0 based on a Cortex-M0 (48MHz). It is a very low cost general purpose 32-bit MCU with up to 32KB flash and 12KB RAM. Our wolfBoot secure bootloader is the only solution available for this platform thanks […]
Read MoreMore TagwolfBoot Support for Renesas RZ/N2L
wolfBoot currently support both Renesas RA6M4 and RX72N MCUs. Supporting other Renesas MCUs for wolfBoot should not be difficult. We are considering the addition of Renesas RZ/N2L support for wolfBoot, which will build on our existing support at the wolfSSL and wolfCrypt level for Renesas RZ/N2L. The Renesas RZ/N2L uses a high-performance Arm Cortex-R52 core […]
