The kas configuration takes the pinned-remote meta-openglow block, with its commit in the lock file (d655e1e, the read-only rootfs), so a fresh clone builds the release without a sibling checkout. The lock keeps the upstream layers where they were. releases/v0.0.1 carries the acceptance artifact the bench exported for this image: campaign c-20260909160235-7649 on 20260909150456, 83 tests, 83 satisfied, none inherited, release authorized. The release gate recomputes every test's fingerprint from the manifest inside the release rootfs and signs only when the recorded results agree.

# ForgeFIRM - kas build configuration (factory Glowforge control board)
|
|
# ============================================================================
|
|
# The forgefirm repo is the BASE: it controls the build and the output firmware
|
|
# images land here (build/tmp/deploy/images/glowforge/). The install, build and
|
|
# release procedures are on the documentation site: https://docs.forgefirm.org/
|
|
#
|
|
# Target : Yocto Scarthgap (5.0 LTS) + linux-fslc 6.12 (mainline LTS)
|
|
# Machine: glowforge (i.MX6 Solo SOM inside Basic/Plus/Pro)
|
|
# Distro : forgefirm
|
|
#
|
|
# kas generates bblayers.conf and local.conf.
|
|
#
|
|
# Run from the forgefirm repo root so outputs land inside it:
|
|
# cd forgefirm
|
|
# kas build kas/forgefirm-glowforge.yml # fetch layers + full build
|
|
# kas shell kas/forgefirm-glowforge.yml # interactive bitbake env
|
|
# kas dump kas/forgefirm-glowforge.yml # show resolved config
|
|
#
|
|
# Reproducible pins (after first checkout):
|
|
# kas lock kas/forgefirm-glowforge.yml # writes kas/forgefirm-glowforge.lock.yml
|
|
