[-7] I/O problem when I'm trying put file into camera - Raspberry Pi3B+ #108

Closed kelerek closed 3 years ago

Hi Jim,

I have a problem with sending file into camera on my Raspberry Pi3B+. When I'm using func:
try: gp.check_result(self.camera.folder_put_file(self.camera_folder_path, self.pic_up, gp.GP_FILE_TYPE_NORMAL, self.convert_to_camera_file, self.context))

except Exception as e: print("Upload Error: "+ str(e))

After using that func I'm receiving this error: [-7] I/O problem.

Have you some advices how can I solve this problem?

If an operation fails (e.g. it's not supported) the USB connection (or other connection) could be left in an undefined state. Resetting the connection might help (maybe a camera.exit camera.init cycle) but you might need to unplug the camera or even reset it.

After a few attempts I didn't find solution.
I can't only send back picture to camera, because USB has some problem with sending back. Program was showing this "[-7] I/O problem" error until reset camera by taking out battery. My camera has ability "sending files to camera".

Have you tried doing it with the gphoto command? If this doesn't work then there is probably a bug in the driver for your camera, or no one has successfully "reverse engineered" the USB commands to do it. Try asking on the gphoto mailing list.
