Q.2: Flashing PX4 with custom bootloader using ST-Link - @mwbb
Objective:
- Flash the bootloader & the program?
- Want to flash the firmware at once for mass (many drones) flashing
Answer:
- Need to build both bootloader & app, and concatenate them (use linker)
- Definitely doable via J-Link, Alex does it frequently. It can even start the app too (can perform tests)
- Matthias has flashed the bootloader via betaflight utility before with this. There’s a documentation on this:
Betafpv supported boards flash PX4 bootloader: Holybro Kakute H7 V2 | PX4 User Guide
But you need to take the correct bootloader for that specific board!
Discussion:
- When this gets resolved, PTurner could contribute documentation on how to do this
Q.3: QGC with Airmap - Farhang
Answer: Ramon will help out, as it is related to QGC.
Q.4: Log streaming inconsistency - I am vd40
Setup:
- Pixhawk with Raspberry Pi
- Pixhawk has SD card installed
- Running v1.13 with customization
Problem:
- Pixhawk doen’st log anything sometimes
- ULog Streaming also shows nothing (when checked via Raspberry pi)
Discussion:
- Maybe CPU priority is depressing logging? > Probably not, because the log file itself isn’t even created
- Started happening 2~3 weeks ago
- The occurrences are not that frequent. Quite rare, but it does happen
Answer:
- Vd40 will create an issue and review from beat will be requested
