rsyslog replaces busybox syslogd/klogd (VIRTUAL-RUNTIME_base-utils-syslog,
trimmed PACKAGECONFIG) and becomes the only log writer: the appended
/etc/rsyslog.conf sets the inputs and the ff_line format and includes
the per-logger rules that `forgectrl --render-syslog` renders from the
machine settings at boot. forgefirm-logrotate becomes forgefirm-logging:
render before rsyslog starts (S19), sweep the pre-syslog log files into
/data/forgefirm/legacy-logs once, and rotate the tree at boot and hourly
by rename + HUP instead of copytruncate. Pins bumped to the pushed
forgectrl (syslog emitter, Logs tab, export), grblHAL-glowforge (syslog
emitter) and python3-gfhardware apps (syslog handlers, capture dir);
the CI harnesses set FFLOG_STDERR=1 so failure diagnostics keep the
controller's log lines. BRINGUP carries the bench validation checklist
(Next work item 14); this is an image change and rides the next flash.
SAFETY.md and the safing figure name GPIO4_06 for what it is - the
readback of the chain's HV_ENABLE output through U24 (the factory net
label E-STOP is kept as a note); BRINGUP records the rename, the
device-tree polarity flip that makes bit 4 read as HV_ENABLE itself,
the removal of the estop_halts_motion opt-in, and the bench check for
the flash that ships it. Recipe pins move to forgectrl 801f1f3,
grblHAL-glowforge b629c18 and python3-gfhardware c3d1790 (PV 0.1.5).
Loop pull sets interlock_latch_reset + interlock_latch within one 50 ms sample and both clear on reinsert; charge_pump_alive tracks the run and falls 0.45 s after the last charge-pump pulse (matches the measured R*C); estop follows it on both edges. Note that an interlock trip parks grblHAL in Door:0 until a cycle start.
docs/SAFETY.md documents the control board's laser safing chain as
reverse-engineered and bench-verified - parts, every net with its SoC pin,
Linux exposure and polarity, the logic, and the software layers ForgeFIRM
stacks on it - with docs/img/safety-chain.svg. Linked from the README.
BRINGUP: Next work item 11 records the interlock-latch finding (an open
loop never tripped the latch; the kernel now drives INTERLOCK_LATCH_RESET)
and the charge-pump watchdog readback, both code-complete and pinned,
bench validation on the next image.
forgectrl ed2934b, grblHAL da4c8eb, forgefirm-app (gfhardware) 6c7534a -
all pushed and fetch-verified, license population checked for the
multi-license recipes.
- kas/README.md: the real-time rationale rests on the feeder's bounded
queue depth, not ring size; the ring is 16 MiB (~84 s at 200 kHz,
~28 min at the 10 kHz cloud tick), a capacity for cloud-mode preload.
- BUILD.md, kas config, release checklist, cold-build workflow: only
forgefirm and meta-openglow (branch scarthgap) are cloned as
siblings; every ForgeFIRM source repo is fetched by pinned SRCREV.
- UPDATE-SYSTEM.md reads as the present-state design: the cloud-mode
compatibility baseline is the cloud client's configured firmware
version, not release metadata; decisions and open items listed
plainly.
- README.md states what GRBL mode still needs the Glowforge service
for (camera-referenced homing) and what runs without it.
- BRINGUP.md: generic build-host and fwup-lab references, the retained
reproductions of the no-fire drill, the System tab.
- LIGHTBURN.md: the arm-window timeouts are machine settings.
- forgefirm-image.bb describes forgectrl as the machine-services
daemon and points at the right backlog entry.
- American spelling throughout.
Pulls in the coarse-pacing fix for parked wait-for-operator states (a
machine left in Door or Hold no longer pins ~28% of the core), plus
P10's grblHAL CI/tests and the mlockall-root-only change. Fetch-verified.
Adds pacing_test.py (dry hold/resume + CPU measurement) and records the
diagnosis and bench validation in BRINGUP.
Phase 5 A-1 emission witness and A-5 HV telemetry pass on live burns;
A-2 lid-IR characterized as a weak signal at 40% (gate left watch-only);
pgood confirmed unusable as a witness on this PSU. Phase 4 X-3 (0.1s
job-based disarm on M2) and G-10 (disarm counts down in Hold) pass.
Adds live_fire_drills.py (arm-lifecycle sampler over TCP + HTTP).
K1/K2/K3 pass on image 20260814223300 with software witnesses
(fire_test A/B/U reproduce the scope-pinned reference); GATE A is
closed and live fire permitted. The campaign caught the liveness
probe's inverted doors-bit guard (forgectrl 424f185, hot-deployed,
probe live-verified MOTION OK).
gate_a_kernel_drills.py stages the three remaining GATE A kernel
drills (controlled-stop deceleration floor, resume waypoint with the
latch locked, mid-ramp latch unlock) with software witnesses and the
PSU-connector scope point. lid_ir_ambient_baseline.csv is the
fire-watch ambient anchor (600 samples, lid closed, machine idle);
BRINGUP records the baseline statistics and the idle verification of
the emission/fire/HV evidence plumbing.
grblHAL CI runs the emission harness, the new armed-window lifecycle
harness, and the switch-map truth table on every push; forgectrl and
the kernel module build -Werror in CI. All three pipelines green.
Emission witness, lid IR fire watch (watch-only until characterized),
faults/HV telemetry, measure-laser cleanup, and the head I2C error fix
(rides the pending image flash); bench items listed.
BRINGUP gains the Phase 4 (stale-gate cluster) record - code-complete,
host-verified, hot-deployable, bench drills listed. LIGHTBURN.md now
describes the job-based armed window: relock at program end, on a
sender change, or after the spindle-off grace (counting even in Hold).
Code-complete and host-verified across forgectrl, the GRBL controller,
the cloud clients, and the kernel module; kernel rows ride the pending
image flash, bench drills listed.
- Move the passwordless-root debug-tweaks image feature out of the
shared kas config into forgefirm-image-dev.bb, so the release
forgefirm-image built from the same config is not passwordless-root.
release.sh gains a gate that reads the built rootfs /etc/shadow and
fails on an empty root password, plus a config-level guard that
debug-tweaks is not present in the resolved kas dump. (B-1)
- The installer copies ffboot out of the signature-verified new rootfs
it already mounts, instead of fetching and executing it from a mutable
GitHub raw ref. (B-2)
- Record audit remediation Phase 2 (GATE B) status in BRINGUP.md,
including the bench pass still required to close the gate.
- LIGHTBURN.md: mandatory "Before you cut" safety section; the
walkthrough now reflects the firing machine (dry runs need the
layer output off or M5; live first-cut instructions); the homing
entry documents homing_mode and the gfcloud method; the machine
address is a placeholder.
- README.md: condensed safety section linking the full text and the
regulatory notes.
- INSTALL.md: "Regulatory and legal" section ahead of the install
steps; routine updates route through the panel updater rather than
the installer.
- BRINGUP.md: the release signing key is described as held offline
(no on-disk path); bench address and credential notes removed;
Next-work item 7 corrected (the installer embeds the production
release key); status entry for audit remediation Phases 0-1; the
GATE A kernel drills join the pending image-flash checklist.
- bench scripts: the target host comes from GF_HOST (or argv) instead
of a hardcoded address.
- laser_stream_test.py: per-session controller runs with a hermetic
cooling-verdict publisher; new assertions that every stream
terminates with FIRE clear (including M3 held to stream end) and
that no FIRE bit rides a zero-step gap; a cycle-churn session
exercises the stop/start seams.
Audit findings D-1, D-2, D-3, D-5, D-10, D-12, B-10, and the harness
half of D-4/G-1.
Add Next work item 9: the panic handler, control_12v removal, decay-mode
state tracking, module build hygiene, SDMA/EPIT/GPIO probe guards and
head_make_safe are code-complete and build-verified, with the bench check
each one still needs and a note that the batch ships with a full image
flash rather than a module hot-swap.
kas/README: drop the control_12v residue (the node is gone), state that
the buzzer driver is not part of ForgeFIRM, and record that the pre-SPDX
LICENSE strings remain only in layers this build does not use.
The controller now maps the door pair and the interlock loop onto the core's
safety-door signal, with the e-stop bit behind a machine setting. Records what
is gated and what is deliberately not, the answer to the audit's latch-reset
question, and the bench items the change still needs.
The interlock_circuit bitmask is fully mapped: b0/b1/b3 from the scope
experiment already recorded in the gate section, b2/b4 from the factory decode
the attributes were ported from, and the armed kill-mid-FIRE drills read the
mask consistently across armed, firing, idle and disarmed states. Trip recovery
was exercised in commissioning runs.
The safety-mapping item now says what is actually left of it: door and e-stop
evdev into the controller's feed-hold and halt path, plus the question of a
software reset path for the laser latch.
README: replace the stalled REST/GUI roadmap with what the firmware does -
GRBL mode over TCP for LightBurn/UGS/cncjs, optional cloud mode, the web
control panel, cameras, A/B install beside the factory firmware - plus the
supported hardware incl. the 8 MP camera limitation and a real roadmap.
kas/README: xvclk is the board's 24 MHz oscillator; the pin/push rule covers
every source repo; camera and motion sections are hardware-validated, with the
OV8856 caveat spelled out; the device-tree item closes with the control_12v
residue named; forgectrl is the machine-services daemon with two supervised
controllers.
LIGHTBURN.md: drop the pre-first-light status line.
BUILD.md: state the NXP firmware licensing and where the EULA lives on the
machine. The image now installs firmware-imx-lic, so the EULA text ships beside
the VPU/EPDC blobs it covers; a bbappend declares that package at parse time,
which is what makes it installable from an image recipe.
Record the finished shared-services state: forgectrl is the one
machine-services daemon behind both controller modes, both controllers
are cooling-engine clients, and the drill and soak coverage that proves
it. Attribute the cooling policy records to the engine's present home.
Add the remaining polish as Next work item 8 - diagnostics as engine
modes, the rail-policy remainder, cloud per-job fan profile
confirmation, /cool/status cosmetics, and button edge detection.
The runbook operational sections now describe the machine as it runs:
forgectrl as the machine-services daemon (supervisor, pulse-device
broker, motion-liveness gate, cooling engine, cameras), controllers
spawned and supervised rather than init-started, standalone driver
runs as the bench/debug exception, diagnostics suspending the active
controller through the supervisor, the cooling engine as the thermal
owner with the drivers as thin clients, and the new /mode and /cool
endpoints. A dated correction closes the no-motion record with the
DRV8825 wedge diagnosis and the liveness/homing hardening; the
cold-start section gains the first-light and shared-services
milestones.
Hardware facts from the 2026-08-11 bench session: the DRV8825 drivers
can come out of a 40 V rail power-up unserviceable (playback and
counters run, motors dead; recovery is a longer true power-off, at
worst a machine power cycle) - so counters/anchors are never proof of
motion and the rail stays up. The head accelerometer is the motion
truth (device mapping, bench-characterized thresholds, read-rate
limits), and every probe move goes +X first - a cable lives at the
end of left travel.
