Question:After flashing the image of Jetson Nano, the TF card cannot be recognized on a Windows computer?

 Answer:

Due to the partition problem, the TF card with the image of the Jetson Nano programmed cannot recognize the drive letter normally on the Windows computer. If you need to reformat it, search for Disk Management in the search bar of windows and open the Disk Management interface. Find the removable disk where the TF card is located (be careful not to mistake it for another disk), right-click and select Delete Volume, then create a new volume and format it by default. After the default format, the drive letter of TF will be recognized again. At this time, the space and memory of the TF card are incorrect. Note that you need to use the formatting software to quickly format the new drive letter again. After formatting, if the memory space of the TF card is normal, the new image can be re-programmed normally.

Question:Why doesn't the motor work after setting up?

 Answer:

Please make sure that you have installed the codes of Waveshare instead of NVIDIA's. The drive codes of the motor are different between Waveshare's and NVIDIA's. If you have updated the one from NVIDIA's, please remove the Jetbot folder and download ours by following step 5.
