Add an NSH command to format a device with littlefs, analogous to
mkfatfs for FAT filesystems. The command unmounts the mount point,
then remounts with forceformat to format and mount in one step.
Enable the command on boards that use littlefs as primary storage
(airbrainh743 and kakuteh7v2), and document it in the airbrainh743
flight controller page as a recovery procedure for a corrupted
flash filesystem.
Usage: mklittlefs /dev/mtd0 /fs/flash
Make the logger practical on small flash storage (e.g. 128 MB W25N
NAND) while keeping the existing SD-card behaviour sensible.
- Move cleanup from boot to log start so logs can be downloaded via
MAVLink FTP before deletion.
- Delete individual .ulg files (oldest first) instead of whole
directories, prioritising the naming scheme not currently in use
(session dirs vs date dirs).
- Add SDLOG_MAX_SIZE (new, default 1024 MB): maximum size of a single
log file. When reached, the log rotates to a new file. The value is
also reserved as headroom in the cleanup threshold.
- Add SDLOG_ROTATE (new, default 90): maximum disk usage percentage.
Cleanup guarantees (100 - SDLOG_ROTATE)% free at all times, even
during writing of a new log file. 0 disables space-based cleanup,
100 allows filling the disk.
- Repurpose SDLOG_DIRS_MAX as an orthogonal directory-count cap
(default 0 = disabled). Useful for capping log usage by count
independent of disk size, e.g. in SITL.
- Drop the implicit ~300 MB free-space floor that used to fire even
with SDLOG_DIRS_MAX=0; space is now governed entirely by
SDLOG_ROTATE + SDLOG_MAX_SIZE.
- Split pure parsing helpers into util_parse.{h,cpp} and add unit
tests (loggerUtilTest.cpp).
- Simplify get_log_time to rely on clock_gettime (set by the GPS
driver); safer string handling in directory parsing.
- Reset _total_written in LogFileBuffer::reset() so callers reading
get_total_written() between stop and start don't see stale counts.

* docs(sim_sih): link Hawkeye visualizer, add stub page
Replaces jMAVSim display-only mode references in the SIH page with Hawkeye,
which is purpose-built for this role and actively maintained. The 3D
visualization section now covers the hawkeye command, the port alignment
with SIH (UDP 19410), and links out to the full Hawkeye documentation.
Adds a short sim_hawkeye/index.md stub covering what Hawkeye is, install
on macOS and Linux, and basic SIH usage. Everything else (multi-vehicle,
ULog replay, HUD modes, CLI reference) lives at px4.github.io/Hawkeye
and is linked from the stub, so PX4 docs don't carry the maintenance
burden of two parallel sources.
Also updates the port reference table: UDP 19410 is now labeled
"Hawkeye visualizer" instead of "jMAVSim display-only", and adds the
page to SUMMARY.md nested under SIH Simulation.
* docs(update): subedit

Update safety.md, remote_id.md, and releases/main.md to document the extended COM_ARM_ODID parameter and the new in-flight failsafe behaviour that will be introduced in PX4 v1.18.
Homebrew 4.5 (April 2026) stopped auto-tapping cross-tap
dependencies declared in formulae, as a security + performance
change. The px4-dev meta-formula pulled in packages from
osx-cross/arm, PX4/px4, and discoteq/discoteq, so 'brew install
px4-dev' now aborts before any real work unless every tap has been
added explicitly. On macos-latest CI runners the chain broke at the
first unreachable dep (discoteq/discoteq/flock) and subsequent make
steps failed with 'ccache: command not found'.
Since Tools/setup/macos.sh is the canonical install path and already
tapped osx-cross/arm and PX4/px4 before calling brew install, the
simplest fix is to inline the package list and call brew install
directly. The px4-dev meta-formula will be kept upstream as a
deprecated no-op so older copies of macos.sh on long-lived branches
and cached Docker images keep working.
The inlined package list is the same set px4-dev depended on, minus
the dead-weight flock dependency that hadn't been invoked in the PX4
build since the NuttX 9.1.x era. See the accompanying PX4/homebrew-px4
PR for formula changes.
Docs updated to match: docs/en/dev_setup/dev_env_mac.md no longer
names the px4-dev formula, describes the package list directly.
Verified locally on macOS ARM64:
- ./Tools/setup/macos.sh runs to completion with both taps and all 13
packages resolving correctly
- make distclean && make px4_fmu-v6x_default builds successfully
