Where Are We Going

Logs, metrics, core dumps, alerting, and OTA are the foundation for firmware observability. They’re not the reason to bet on a specific observability platform for the next two years.

The bet is on what comes next.

We’re building Spotflow toward automated firmware operations. Tooling that doesn’t just collect telemetry but autonomously reasons about it and suggests improvements to your firmware. Our goal is to reduce the time between detection and fix as much as possible to keep the impact minimal.

Let’s imagine pushing a firmware update on Tuesday and waking up on Wednesday to:

  1. [ 01 ] Crash spike detected
    Wed 07:14:02

    The crash rate has risen to 8% on hardware revision NXP Lock Gen2, firmware 1.2.1, following Tuesday’s update. 1,862 devices affected.

  2. [ 02 ] Root cause identified
    + 00:47s

    New BMI330 sensor driver version 3.47.0 contains a race condition in sensor_init().

  3. [ 03 ] Recommended fix
    + 01:05s

    Downgrade the BMI330 sensor driver to version 3.46.0.

  4. [ 04 ] Resolved
    Wed 07:21:48

    New firmware version 1.3.0 with a downgraded sensor driver was deployed to the fleet. Current crash rate is below average, at 1%.

That’s where we’re heading.
