Waiting for bootloader on setup

Hello everyone,

I try to upload firmware to px4 connected by USB.
Use this command from guide.
make px4fmu-v3_default upload

After compiling i got this line and nothing happened?
waited for bootloader

I waited about 1 hour. Nothing happend.

My current system is wsl Ubuntu 22.04.3.

I know that my px4 works. My drone flight. I uploaded firmware by QGCS and Mission planner. All worked fine.
What’s wrong? i couldn’t find any topics about this.

I think you did not run this command before upload:
bash ./PX4-Autopilot/Tools/setup/ubuntu.sh
You can folow this page to do what you want.

Apologies for responding to a year-old thread. Have you found a solution? Could it be that you did not mount your pixhawk to wsl?
