Since a few days ago, whenever I tried to launch
rosbot_ekf using the Husarion Ubuntu 20.04 ROS noetic image, I got
unable to sync with device, possible link problem or link software version mismatch such as hydro rosserial python with groovy Arduino.
Therefore, I tried to update the firmware of ROSbot. I followed the instruction here (CORE2 | Husarion and Firmware update fail - ROSBot2 Pro - #2 by Karol_Konkol) and ran
./flash_firmware.sh on tinkerboard. I got an error as shown below.
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 ....
I also tried to reinstall the system and run
./flash_firmware.sh to solve this problem. However, I still got the same error.
Now I have no idea how I can fix it. Everything worked fine before. Any guidance will be gratefully received. Thank you in advance.
