Integrators can declare read-only parameters in a per-board YAML file:
readonly_params.yaml.
There are two ways to define the read-only params:
- "block": default writable, explicitly list params to be locked
- "allow": default readonly, explicitly list params to be writable
Enforcement is activated by `param lock` in rcS after all startup
scripts have run, so board defaults and airframe scripts can still set
params during init.
The feedback via MAVLink uses the new
MAV_PARAM_ERROR_READ_ONLY as part of the PARAM_ERROR message.
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
---------
Co-authored-by: Hamish Willee <hamishwillee@gmail.com>
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.
