Avatar²

What Avatar² is

Avatar² is a free, Apache-2.0 licensed Python framework for dynamic analysis of embedded-device firmware. It coordinates targets, memory layouts, and execution plans to distribute firmware execution across targets, which communicate through protocols with emulators, analysis frameworks, or physical devices. Documented targets include GDB, OpenOCD, J-Link, QEMU, and PANDA. OpenOCDTarget connects to physical hardware over JTAG, while JLinkTarget supports SWD and JTAG. PANDA support includes execution recording and replay, as well as loading, unloading, and listing analysis plugins. Memory layouts define regions and forwarding rules for reads and writes between targets. The project documents installation through pip, source, or Docker; QEMU and PANDA are Docker defaults. It supports Linux and lists ARM Cortex-M3 and x86-64 architectures. The README provides target build scripts for Ubuntu 20.04; other distributions are not officially supported, though they may work with modifications. Maintained by EURECOM’s Software and System Security Group, the project directs users to a public mailing list and an invite-based Slack community.
