Greetings, esteemed community. I need help. I am a beginner working with this microcontroller. All I found was the standard way to flash the cube through Mission Planner. But I have my own code, my own firmware on STM32CubeIDE. How can I flash the Cube with my firmware using this development environment? I also have an ST-Link v2 available, but I also need help on how to connect these 4 cables (the board set up is HannStar K MV-4 with Type-A connector). …

Purchase an STLinkv2 ([search on amazon](https://www.amazon.com/s?k=STLinkv2&crid=2NZ96UDD87WGC)) Ensure you have an [ArduPilot build environment setup](https://ardupilot.org/dev/docs/building-the-code.html) If using Windows PC running WSL2 (and VSCode) as I do then you will need to download and install [WSL USB Manager](https://gitlab.com/alelec/wsl-usb-gui/-/releases) to allow WSL2 to access the PC’s USB ports Open the Cube’s carrier board and connect to the STLink as shown below [stlink-cube-wiring-corrected] …
