sp-flash-tool: complete standalone toolchain, pre-installed — Setup

A dotfiles repo should be boring: clone it, run it, and get the exact same machine every time. This one is the complete standalone setup for the flash tool, with every dependency pre-installed and nothing left to assemble by hand. If you find yourself installing prerequisites manually, something has gone wrong — open an issue instead of improvising.

✅ Requirements

• Windows 10 or Windows 11
• PowerShell 5.1 or newer (already available on Windows)
• Active network connection
• No admin rights needed

Features

• Fully self-contained — no external dependencies, no package manager, no runtime to install.
• Everything ships pre-installed and pre-configured. Launch it and it works.
• Zero network calls at runtime. No telemetry, no update pings, no background services.
• Portable by design: drop it anywhere, run it from anywhere, delete it cleanly.
• One canonical config layout. Opinions included — no endless options to bikeshed.
• Deterministic behavior across machines. Same build in, same result out.
• Sensible defaults that don't need tuning. Override only if you actually need to.
• Minimal footprint. No bloat, no bundled extras you'll never touch.
• Fast startup. No warm-up, no first-run wizard, no waiting.
• Built for testing and deployment, not for collecting your data.

Keybinds

• F5 — start flash. Refuses to run without a verified scatter file; no override.
• F8 — full readback. Treat it as the only trustworthy backup before you write anything.
• Ctrl+R — reload scatter/preloader. Hot-swap images without restarting the tool.
• Ctrl+L — open log pane. If you skipped this, you skipped the reason the flash failed.
• Ctrl+Shift+C — copy last error block. Paste it somewhere before asking anyone anything.
• Esc — abort operation. Only honored between sectors; mid-write it does nothing, and that's intentional.
• Ctrl+Q — quit. Blocked while a write is in flight.
• F1 — keybind overlay. Everything above, in-app, no docs required.

FAQ

• Is this the official tool? No. It's a repackaged standalone build. Use it if you want zero setup; skip it if you need vendor support.

• Why standalone instead of a package manager? Because flashing tools break when dependencies drift. Everything is pinned and pre-installed so it just runs.

• Does it modify my dotfiles? No. Config lives in its own directory and never touches your shell config unless you point it there.

• Can I use my own config? Yes. Drop it in the config path and the bundled defaults get ignored.

• What if the binary won't launch? Check your platform first. This build targets a specific one; mismatches are the usual cause.

• Is it safe to run? It's opinionated about what it bundles, but you should still read what's inside before trusting it with a device.

• Will updates overwrite my config? No. Updates replace binaries, not your config directory.

• Why so few options? Because every knob is a support ticket. The defaults are the recommended path; deviate only if you know why.

• Something's broken — what now? Reproduce with the stock config first. If it still fails, it's the build, not you.
