Update MavFTP code, add MavFTPfs example/tool

This mounts mavftp as a virtual filesystem, which allows for more "human" interf…acing with it. There are caveats. It is obviously slower than doing things on your own machine. but this does allow interfacing using any filebrowser, for instance. So far the filesystem is mounted as read-only. as there's no mavftp interface to write to a sector of a file, we'd have to create an abstraction layer that caches the whole file...

Operate the vehicle within radio range of the radio transmitter. If the vehicle… is unable to operate the radio, we want to make a hard landing on the spot as an emergency response. For this purpose, TERMINATE is added to the radio fail-safe designation. ![Screenshot from 2023-09-21 00-41-25](https://github.com/ArduPilot/ardupilot/assets/646194/01f560e5-ede4-4225-bf59-d93852d42a6e) ![Screenshot from 2023-09-21 00-39-32](https://github.com/ArduPilot/ardupilot/assets/646194/86bdf0a4-ae6e-4bcf-a92a-3c9ca2d72b58)

This PR allows us to populate the [`CAMERA_INFORMATION`](https://mavlink.io/en/m…essages/common.html#CAMERA_INFORMATION) and [`VIDEO_STREAM_INFORMATION`](https://mavlink.io/en/messages/common.html#VIDEO_STREAM_INFORMATION) MAVLink messages from Lua scripts. Sending these messages allows a GCS to auto-configure the video stream to receive video from the payload. Replaces https://github.com/ArduPilot/ardupilot/pull/27594.

Over time the current iteration of the generator has drifted from the actual cod…e, both due to changes within itself and in the used libraries. This PR tracks down how that's happened and makes everything consistent again so that informed improvements can be made. * Code generator is modified to automatically use `sq` and friends. * Old generator versions that generate the current code have been dug up. * Generators ensure the correct version of SymPy is used (1.9) * [Nix](https://nixos.org/) shell script added to conveniently use the correct versions of the generator libraries. * Outdated previously generated code is removed from the repo. * Unused generated code is disabled. No compiler output change (on CubeOrange at least).

Reduce overhead when doing SPI transactions

* Tested on CubeOrangePlus and CubeRedPrimary with Invensensev3 driver * I us…ed debug trace to analyse timeline for read_fifo to check if we have any substantial overhead while doing SPI transactions. It turned out that calling spiStart and spiStop which in turn call dmaStreamAlloc and and dealloc to take substantial amount of CPU call almost 3-4us. Also we were calling Shared DMA mutex lock and unlock when the DMA is not shared between peripherals. * Following changes made SPI transactions much less CPU intensive: - * Do not reset SPI peripheral using spistop and spistart calls if SPI config hasn't changed. - * Also make changes to SPI frequencies for CubeOrangePlus and CubeRedPrimary to match on the bus where possible (minor CPU gain through this, just first part was enough as most transactions are IMU anyways). - * Do not call mutex lock unlock for unshared DMAs. Results: CubeRedPrimary: Before: SPI1 PRI=181 sp=0x20001AA8 STACK= 792/1464 LOAD=13.4% SPI4 PRI=181 sp=0x200021C0 STACK= 872/1464 LOAD=13.4% SPI2 PRI=181 sp=0x20005380 STACK= 896/1464 LOAD=13.3% After: SPI1 PRI=181 sp=0x20001B08 STACK= 792/1464 LOAD= 9.7% SPI4 PRI=181 sp=0x20002220 STACK= 792/1464 LOAD=11.2% SPI2 PRI=181 sp=0x200053E0 STACK= 840/1464 LOAD= 8.3% CubeOrangePlus: Before: SPI4 PRI=181 sp=0x3002AF58 STACK= 668/1464 LOAD=25.5% SPI1 PRI=181 sp=0x3002B668 STACK= 668/1464 LOAD=14.5% After: SPI4 PRI=181 sp=0x3002AF78 STACK= 668/1464 LOAD=19.2% SPI1 PRI=181 sp=0x3002B688 STACK= 668/1464 LOAD= 9.5% >10% total CPU time recovered for both CubeOrangePlus and CubeRedPrimary

GCS_MAVLink: Check if set_message_interval is too fast

ArduPilot:master ← stephendade:loop-interval

opened 10:37AM - 18 Sep 24 UTC

stephendade

+33 -7

From #28101. Ardupilot caps the maximum message rate at 80% of ``SCHED_LOOP_R…ATE``. If a user requests a rate faster than this via ``MAV_CMD_SET_MESSAGE_INTERVAL``, the command now fails and advises the user to increase ``SCHED_LOOP_RATE``. This will prevent user confusion as per the linked issue. Tested in SITL.

DroneCAN: fixed deadlock and saturation of CAN bus

ArduPilot:master ← tridge:pr-fix-can-deadlock

opened 11:00AM - 24 Sep 24 UTC

tridge

+12 -22

This fixes a set of issues found on investigating a watchdog from @lthall PR… depends on: https://github.com/dronecan/libcanard/pull/72 The situation was: - a H7 with mavlink over serial over DroneCAN setup, MissionPlanner connected to the serial port - SERIAL1_PROTOCOL set to GPS, with GPS1_TYPE=AUTO, but no GPS plugged in There were several interacting bugs: - the canard layer could run out of buffer in its allocator part way through a message send, resulting in sending just some of the frames onto the bus, which results in a corrupt message, wasted bandwidth and broadcast() returning false - MissionPlanner sends CAN_FORWARD requests on all connections, regardless of type, which on a CAN serial port means it is requesting to send it's own packets over CAN, resulting in an "infinite" number of packets and complete bus saturation - MissionPlanner issue here: https://github.com/ArduPilot/MissionPlanner/issues/3417 - once the bus was saturated, serial.update() in the DroneCAN thread would not make any progress, which meant it would keep trying to send the same bytes forever, but no full messages could ever be sent, so from the users point of view the CAN bus is dead (the UI shows no messages, as all messages are corrupt) - the lack of a sleep in the DroneCAN thread meant that all threads of lower priority would stop running, including UART threads, the main thread keeps running - the main thread then tries a begin() in AP_GPS for a new baudrate, the UART thread is still stuck in TX from the last set of GPS probe bytes and can't make progress due to the higher priority DroneCAN thread running non-stop - the main thread then gets stuck waiting on the _in_tx_timer boolean lock, causing the main thread to lockup - this triggers a watchdog

AP_GPS: Suppress unnecessary telemetry transmission

ArduPilot:master ← muramura:AP_Suppress_unnecessary_telemetry_transmission

opened 11:56AM - 24 Sep 24 UTC

muramura

+4 -0

If data cannot be obtained from the GPS device, telemetry transmission should be… suppressed. The GCS can detect a device malfunction if it is unable to receive telemetry from the GPS. Since the GCS on the transmitter has a narrow bandwidth, refraining from sending meaningless telemetry data allows the bandwidth to be allocated to other telemetry.

AP_BattMonitor: add option minimum volt option

ArduPilot:master ← robertlong13:pr/sum_monitor_min_voltage

opened 03:10AM - 25 Sep 24 UTC

robertlong13

+28 -6

Alternative approach to #28148 This solves the race condition issue and the W…h consumption calculation. Instead of calling `update_consumed` again, it sums the consumption calculation from the other monitors. This is actually much better than integrating it again manually, especially if the underlying monitors are better at calculating the consumption. I also removed the implementation on the ESC battmon backend (and updated the param docs and comments to match). I don't think it was nearly as important to have this option for the ESC backend and I couldn't use the same trick with that one.

Fix mission item logging

peterbarker

+111 -70

In master we use the "CMD" log message to log both items as they are uploaded *a…nd* when one of the vehicles actually start to execute the commands. This is weird. This PR creates a separate log message, `MISE` which is emitted by the AP_Mission library as it starts the execution of an item. This is a behavioural change; we now log all items, rather than just the ones that the vehicles handle. I've tested Plane creates the messages appropriately, but need to look at the other affected vehicles.

GCS_MAVLink: Common: Allow scripting to receive messages which fail CRC check

This allows scripting to receive messages which the flight controller does not u…nderstand. Note that more work is needed to allow sending. This uses https://github.com/ArduPilot/pymavlink/pull/983. Tested new CRC check with MAVLink 1 and 2. Tested unknown messages by changing the CRC extra of command long in ArduPilot so it would fail its CRC check, it still works as normal in the script.
