[Solved] Checksum does not match

I am trying to install ROS2 foxy support on my ROSbot 2.0.
I am looking at ROS2 Demo for ROSbot 2.0 | Husarion for guidance.
After Flashing STM32 firmware to rosbot-2.0-fw-v0.14.3.bin.
The following operation fails:
source /home/husarion/husarion_ws/install/setup.bash
ros2 launch rosbot_description navigation_demo.launch.py

Hi EdSeymore

This question is redundant to the one from this topic. When you succeed with flashing the firmware, those errors should disappear, so I hope you don’t mind me closing this thread and redirecting it to your other question.

Best regards,
