We have run into an issue with our data flash logs when using v 2.78. It seems the on board logger is recording only the later of our 35-45 minute missions. Perhaps there is a simple fix for this issue but we don’t quite know how to address it. We clear the logs after each mission so there should be ample storage space on the APM. It looks like there is 87 events where the camera trigg was recorded yet we have 310 images in the file. I would attach a copy of the log but it exceeds the limit of the file size allowed. If anyone would like to review them please send me a location to where I can send them. I would be happy to. Thanks for having a look and I look forward to a resolution.
