I have an old Pixhawk1 but recently I have some problems loading a new firmware either because I installed macOS Big Sur or because there was an update to Qgroundcontrol.
When I try to load the firmware from Mac I get this message
If I try to load the firmware from Virtual box with Ubuntu 18.04 I get this other message
I also tried to load firmware using the development environment via the command make px4_fmu-v2_default upload but it asks forever for the board as you can see in the image below. I disconnected and reconnected multiple times but nothing.
Last but not least, after booting up in Qgroundcontrol it says No CPU load information and it does not allow me to arm it.
Any help would be greatly appreciated.
Thanks a lot
