summary
A new reference board called Sparrow Hawk packs 4x Cortex-A76 + 3x Cortex-R52, an AI accelerator for CNN, Raspberry Pi camera/display headers and automotive interfaces (CAN, GPU, USB). Zephyr boots as proof-of-concept on R52 (single-core, serial driver), on A76 with an E2 boot workaround for non-relocatable images, and as dom0/domU under Xen; Yocto/Debian/Xen/Zephyr BSPs and schematics are published on GitHub. Board ships January 2026 for $300 USD.
