How it works · Hardware interaction
Build, flash and debug firmware in one AI loop.
Generating code is the easy half. Flash runs the build, flashes the target, and reads what comes back, so firmware and hardware stay in one feedback loop instead of two disconnected steps.
The build–flash–debug loop
Builds with your toolchain
Runs the build you already use — PlatformIO, ESP-IDF, Zephyr/west, or CMake — and reads the compiler output, warnings and all.
Flashes and watches
Programs the target and streams the serial monitor, so the agent sees what the board actually does after the code lands.
Closes the loop
Build errors and runtime traces feed straight back in as the next iteration — no copy-pasting logs into a fresh prompt.
Evidence through one iteration
- 01
Build
Run the project toolchain and capture the exact diagnostic.
- 02
Resolve
Connect the failure to the board model, source symbols and relevant datasheet evidence.
- 03
Flash
Apply a reviewable change, rebuild it and program the configured target.
- 04
Verify
Read serial or debugger evidence and return the result to the same task context.
Why it matters
The bug shows up at runtime — so the loop has to reach runtime.
Most of firmware is the iteration: build, flash, observe, adjust. By living inside your existing build and serial tools, Flash turns each failed build or odd trace into the input for the next attempt — and meets your workflow instead of replacing it.
