A couple of nights ago, my camera started playing up. After successfully recording five exposures of 300 seconds, at the end of the next imaging period of 300 seconds, the captured image was not downloaded to the RPi4 with the Indi driver indicating that there was an 'unknown error', and the camera display showing the number of remaining exposures on the SD card continuing to flash. When eventually, after various steps of attempting to get it to carry on working, I went to turn off the power the screen showed an animated rotating image saying Recording...Remaining Images :1. Since then I have tried various cures including changing power supply from mains adapter to battery and back, updating the camera firmware to the latest version, and changing SD cards, even though the images are not normally saved to the SD card.
Has anyone encountered this before, and any good ideas for solving the issue?
One final 'cure' remains for me to test, to attempt to drain down the internal power source which maintains the date and time and camera optional settings. I have removed the main battery, but I haven't a clue how long I will need to leave it to drain down, or if this may be any help at all! By the way, the camera seems to function quite normally when used in standard camera modes (P, AV, T, Auto etc) with shortish exposure times up to half a minute.
I am using the Astroberry Server 2.0 on my Raspberry Pi 4 4GB, and have carried out a sudo apt update && sudo apt upgrade, but otherwise not looked deeper at which Indi driver I am presently using.
