EdgeForge unblocked a new edge product line stuck on unstable HAL layers. We owned BSP integration end-to-end — kernel config, HAL contracts, CTS-inspired validation, and reference AOSP builds per board — so application teams could ship against a trustworthy image family instead of chasing vendor flakes.
AOSP and BSP integration kits for edge devices, including HAL adapters, driver bring-up, and device validation suites.
Narrative
How the engagement moved from constraints to a shippable system.
Approach
We owned BSP integration end-to-end: kernel config, HAL contracts, CTS-inspired suites, and reference AOSP builds per board.
Solution
EdgeForge BSP delivers reproducible images and a validation matrix that application teams can trust.
Scope
What we delivered
Reproducible AOSP images for three board variants
HAL contract and driver bring-up documentation
CI flash + validation matrix
CTS-inspired device suites
Application team integration guides
Highlights
What stood out
Three board variants under one image family
HAL contract tests in CI for every flash
Application teams unblocked within a quarter
Clear ownership between vendor, BSP, and app layers
Engagement flow
A repeatable rhythm from discovery through hardening — tuned to this product’s constraints.
01
Board triage
Ranked instability sources across kernel, HAL, and vendor blobs.
02
Contract definition
Wrote enforceable HAL contracts and validation expectations.
03
Image factory
Automated reproducible builds and flash pipelines per board.
04
App handoff
Enabled application CI against golden images with clear defect routing.
