I am currently working on a computer vision project with the Leo Rover. I need to collect camera images and IMU data simultaneously at a high rate using ROS. I have been encountering issues collecting data.
I thought that maybe using a micro SD card with a higher write speed could improve this process. Therefore I used this command to copy the content and partitions of my old SD card
sudo dd if=/dev/sdb of=~/raspberry_backup.img bs=4M status=progress
I flashed it onto my new sd card with the command :
sudo dd if=~/raspberry_backup.img of=/dev/sdb bs=4M status=progress
When I checked the content of the new SD card with the file manager, everything was exactly like my old sd card. However, when I plugged it in the rover the light blinked indefinitely and never emitted any wifi signal. The ethernet connection doesn’t work either. I tried to plug the old card in the rover but it also doesn’t work anymore.
I am using the Leo Rover < 1.8 with the Husarion Core2-ROS board.
