We have two robots (ROSbot2 pro) where firmware is not updating using the latest Husarion Ubuntu 20.04 ROS noetic image. Other other robots using same image update firmware without issue. We don’t know why these two robots should be different.
Attempt 1 Can't init into bootloader: Can't read port or timeout
Attempt 2 Can't init into bootloader: Can't read port or timeout
Any guidance will be gratefully received, thank you.
