Open-source embedded debugger with gRPC API for programmatic hardware control.

• Debug ARM Cortex-M via ST-Link, J-Link, or CMSIS-DAP probes
• gRPC API for programmatic control (halt, step, read memory, set breakpoints)
• RTT logging with 1MB/s throughput
• DWARF symbols for source-level debugging
• SVD peripheral decoding for register inspection
• Rust type support (Vec, Option, Result pretty-printing)

• aether-core - Probe communication, symbol resolution, RTT handling
• aether-ui - egui-based GUI
• aether-agent-api - gRPC server for remote control

• Rust (latest stable)
• Linux: libusb-1.0-0-dev, libudev-dev
• Windows: May need Zadig for USB driver setup

Aether is a workspace with several components. You can build them individually:

cargo run --package aether-ui

# Start the daemon
cargo run --package aether-agent-api --bin aether-daemon

# Use the CLI to interact
cargo run --package aether-agent-api --bin aether-cli -- probe list

The firmware is excluded from the default workspace build to speed up environment setup.

cd aether-demo-fw
cargo build

The UI will auto-detect connected debug probes.
