Hello
Ii am doing the same things like in this link. I am just using the Lepton3.5 Camera and use the breakboard v1.4.

When I want to start my

I have use ‘install libgtk2.0-dev and pkg-config’ install libgtk2.0-dev and pkg-config

Have you tried “sudo apt-get install libcanberra-gtk-module”? Not sure if this is what is needed.

Thank you for your reply,
but the following problem still occurs

Hi,
We don’t have much exerience about the application. Would suggest check with the github owner for further suggestion. You may confirm which Jetpack version is used for the application. It may be validated on certain version.

Something to add about why you might check with the actual software vendor: If there is something in the software that expects a certain GPIO pin to be used, and it is different hardware, then you’d need a device tree edit or a program edit to work with the Jetson’s GPIO. I have no idea if this is the case, but it is important to know that some hardware does need to be told about customizations to use it. A USB camera would not have the issue since it is plug-n-play, but something with an alternative interface (e.g., MIPI CSI) which is intended for another platform (e.g., a different model of Jetson, or a Jetson module that is the same but on a different carrier board) can break how it works. The vendor of the software might be able to point out some issue.
