wolfSSL is excited to announce wolfBoot support for Aarch64 platforms with out-of-the box examples for Xilinx ZynqMP and Raspberry Pi 3+.

On the Xilinx Zynq UltraScale+ MPSoC wolfBoot can replace U-Boot to provide enhanced support for feature such as:

Boot failure detection and use of alternate secondary image. Update swapping of partitions. Image integrity checking SHA256 or SHA3-384. Validation of the signature using ECC P256, ED25519 or RSA (2048-bit or 3072-bit). Root of trust options: Key embedded in wolfBoot image partition Key from TPM 2.0 module using wolfTPM (ST33 / SLB95670 / ATTPM20) Key from secure elements such as ST-SAFEA100 and ATECC608A

New Features:

Added Aarch64 boot/startup support Added configuration templates for Raspberry Pi 3 and Xilinx ZynqMP UltraScale+ Added Xilinx Zynq QSPI bare-metal Driver Added NO_XIP option for full ext_flash_* API on all partitions Added Xilinx SDK Project Template Added support for DTS image partitions Added Aarch64 GICv2 initialization code Added wolfBoot signing tool in Native C (tools/keytools/sign.c) (and Visual Studio project) Added libwolfboot functions: int wolfBoot_fallback_is_possible(void); int wolfBoot_dualboot_candidate(void); Performance improvement to only hash application firmware image once
