BYE freezes when downloading, image not making it from camera to laptop

[jtackett]

Hello,

 

Searching through the forum has me suspicious that the problem I'm having may be the dreaded missing "image ready for download event" issue. Would you please mind helping rule that possibility in or out?

 

I have been using a Canon 550D on Windows 8 with BYE 3.1.3. with no issues for quite some time. Last week began running into issues where BYE will say the image is downloading, but it never actually downloads and I have to end BYE with the task manager because it has locked up. After this happens, the image which the camera is attempting to download never makes it anywhere. I tried different USB cables, different USB ports and a different computer with the same results. I also removed the battery for several minutes.

 

Last week I gave up on imaging the night this happened, removed the battery and came back to it the next day. I reinstalled EOS Utility and reset the camera settings in the menu. Not sure if any of this helps, but something worked. I was able to download again and imaged several nights in a row with no problem except one night where I found the BYE hung up waiting on the image to download. The next night everything worked fine.

 

Tonight I launched into a sequence of darks, but when I aborted the sequence after awhile, BYE locked up waiting on a download. The same tricks that worked last week (removing battery for 10+ minutes, reinstalling EOS utility) aren't working tonight This is all rather inconsistent.

 

Do you think looking at the BYE logfile would help narrow down if it is the missing "image ready for download event" issue? If so, I can email it to you.

 

Thank you for any help. Please let me know if there is more information I can provide.

I have seen a few cameras in the past not firing the image ready for download event and your scenario seems in line with this.

 

Yes, I would be able to tell your if this is the issue by looking at the log file.

Thank you, Guylain. I will send the log file to you in a moment.

Thanks for the log files.

 

Your camera is shutting down.

The camera has actually fired the event StateEvent_Shutdown which means it is turning off on its own.  I do not know why it is shutting down.  Do you have a fully charged battery?  Are you on AC Power?  if yes is it cheap after market ac adapter?  Do you have your camera to shutdown after x minutes?

Thank you for having a look at the log files. Much appreciated. Well that is some interesting information. Now that you mention it the 12V to Canon battery adapter I use has acted fishy in the past. Sometimes the charge indicator on BYE will go from full to about half out of nowhere. On those occasions, I take the battery out of the camera and place it back in. Usually, the battery indicator goes back to full. So there could be something up with that adapter. I will also check the voltage of the marine battery I'm using and the auto power shutoff setting in the camera. Thanks for the leads. It will be a big sigh of relief if it isn't the camera and just an issue with power accessories. 

 

Thanks again,

Jason

Jason,

 

The battery charge property that is provided by the camera  has 5 levels:

 

        public const uint   BatteryLevel_Empty    = 1;   
        public const uint   BatteryLevel_Low      = 30;      
        public const uint   BatteryLevel_Half     = 50;      
        public const uint   BatteryLevel_Normal   = 80;
        public const uint   BatteryLevel_AC       = 0xFFFFFFFF;     
 

So, you should not expect it to count down a percentage at a time throughout your session. Not sure how it behaves when the battery is remove and reinserted without being charged.

Thanks for the details. The discrete steps make more sense now.
