feature-request

## :exclamation: About 💡 For the upcoming v1.15 release, we are asking the Comm…unity for flight tests. This issue will be used for keeping track of all the tests from the Community. If you're unsure about upgrading, please read the preliminary release notes on the PX4 docs. Pay close attention to the Upgrade Guide before deciding if v1.15 is right for you. - [v1.15 Release Notes](https://docs.px4.io/main/en/releases/1.15.html) ## Pending Issues - ## ❓ Why we need flight testing 🌏 Thousands of people around the world depend on the stable release of PX4. 🖐️ Before every major release, as much testing as possible is needed to ensure that our release actually works! 😯 Simply said, **more testing = better release** 🤗 We would like to encourage every community member to join us in improving PX4! ## 🤷 How you can help with flight testing 😱 Even if you have never contributed a flight testing report, fear not! Please follow the steps below for the details of how you can contribute to flight testing. 1. **Select** a category from the "flight testing matrix" below 1. **Flash** the firmware (documented below) 1. **Test** 1. **Upload** the log (documented below) 1. **Report** the test in this issue thread! ### :bookmark_tabs: Flight testing matrix 📖 **Here are the table of things we need tests for.** This will constantly get updated, and your contribution to testing the missing slots (tests needed) will be greatly appreciated! | Title | Description | Vehicle/Hardware requirements | Testing procedure | Test logs | Related issue/posts | |---|---|---|---|---|---| | General | By testing your usual setup, we want to capture any regression / weird behaviors you may notice | Any | Test what you usually use for your personal usage, and report it to the comment below | | | ### How to flash v1.15 beta firmware ![beta_flashing](https://user-images.githubusercontent.com/23277211/230138126-c7b02c00-f07b-4a4f-b6b7-866d69db6520.png) 1. Open QGC 3. Click the Q icon on upper right > Vehicle Setup > Firmware (Step 1 in picture) 4. Connect your flight controller to the computer 5. When the Firmware setup window pops up, click "Advanced settings" checkbox 6. Select "Beat Testing (beta)" from the drop down (Step 2 in picture) 7. Click "Ok" This should automatically flash & reboot your flight controller with the latest v1.15 beta release! ### How to share your log First, retreive the log from the flight controller in QGC Q icon > Analyze Tools > Log Download, and find the log you want to download. ![log_uploading](https://user-images.githubusercontent.com/23277211/230143915-4dad89ec-ab6d-43f3-9e5f-7a4624faa56e.png) Then: 1. Go to https://logs.px4.io/ 2. Click on "Flight Report" tab (this allows public viewing of the log in the [browse page](https://logs.px4.io/browse)) 3. Add the ULog file 5. Fill in the description, feedback, and video URL (if available) 6. Click "Upload" 7. Copy and paste the link of the log, and share it to this thread When posting on this thread, please mention what kind of test it was (especially if it is one of the testing matrix options) & general info behind it! ## Questions? Feel free to ask any questions regarding flight testing in the #dev-team channel in the [discord server](https://discord.gg/dronecode)!

mavlink log handler rewrite for improved effeciency

Fixes https://github.com/PX4/PX4-Autopilot/issues/22998 The main reason for d…oing this is to fix the above issue where a LOG_REQUEST_LIST pegs the CPU at 100% for multiple seconds. If you look at the original code, as it is before this PR, you will see the primary culprit is the redundant calls to stat. I've improved the method of constructing the log list file so that it doesn't take multiple seconds. There's no longer any CPU load during the request_list. Creating the logdata.txt file (with 28 entries) ``` mavlink: create file: 16 events, 1045295us elapsed, 65330.94us avg, min 59106us max 74291us 6038.570us rms ``` Listing the entries (28 of them) ``` mavlink: listing: 16 events, 110504us elapsed, 6906.50us avg, min 6102us max 8128us 989.786us rms ``` I started a log to record the CPU usage while downloading a bunch of logs. The CPU usage during log download remains the same and the download speed remains the same (roughly 5Mbps). ![image](https://github.com/user-attachments/assets/e915fb8a-bf15-4e9f-a299-234295f6ca67) My last remaining concern is USB CPU usage in general. Should we put some kind of artificial cap on USB data rate to limit the CPU usage? Flash increases by **832 bytes** -- almost all of the increase is the added LOG_WARN. In the previous implementation the warnings are not compiled in.

[Sponsored by CubePilot] stm32h7: Reset USART clock selection

PX4:main ← PX4:pr-fix-usart-clock

This resets the USARTs' clock source selection to the default, in case it has be…en changed by the bootloader. This is required if booting from the ArduPilot bootloader which happens to reset the clock selection to PLL. Without this fix, UARTs (including the console) is garbled, so presumably at an invalid baudrate. I suspect this will solve a lot of frustration where serials "just don't work". I have added defines for Pixhawk 6C and 6X, as well as CubePilot Orange and Orange+. I assume we need to add this to a bunch more boards. Depends on https://github.com/PX4/NuttX/pull/319. Needs backporting to v1.14 and v1.15!
