Dear All,
I recently installed a ubuntu mate on a Rpi3 (with an SD of 128Go). I installed a full prepared image installed "nafabox" it is a mate distrib with all tools already installed, very easy). I read many posts with some equivalent troubles with canon DSLR, sometimes it gets resolved but solution is not described. I spent nights testing many settings and i can't get away from having troubles with the camera connected to the pi3 & indi.... So i finally come here to seek for help as i am totally lost.
On the config side : i want to control everything from the rPI3 : Meaning : the mount (NEQ6) and the DSLR and store my night session shoots also. I will control from a wifi tablet everything.
In Ekos all seems OK at first view : the DSLR is recognized and connected, i can change settings (ISO, etc..) the control seems all perfect.
but, If i try a "preview" from ekos or a shooting of 2 exposures, the camera starts and finish the exposure at the right time expected, but the file cannot be retrieve from the camera. Then i cannot try again, i have to cycle power off from the camera, stop the indi then restart everything back.
I tried many many times with many many different settings :
- i unchecked firstly the preview to avoid loading the shoot on the screen, avoiding maybe filling too much of memory
- tried with FITS, tried in Native. [expecting FITS takes longer and may add troubles]
- tried with RAM saving, tried in SD (option save and delete) [expecting the RAM was getting filled?, but i would be surprised]
- tried with fast exposure 0,2 and tried with 20sec : same results
- When i do a "live view" from ekos control panel : i can see the live view. when i stop it stops well (note than from time to time the miror doesn't go back and the software is not able to start a shooting.. but it appears rarely to be honest)
- I tried to do firstly a live view of a few seconds then the shooting : same results.
- i tried to also do a first shoot from the camera body prior to start the shooting from ekos/indi : same results
- Lately i also tried with the gphoto driver and redid all same config testing... [ i read in several posts than for canon DSLR it was sometimes better to use gphoto]
-> the results with gphoto is that i get a message box saying the indi driver crashed (always at the end of the exposure) ! (independently of the settings FITS/NATIVE/RAM/SD etc...)
- i updated the full packages (update & upgrade) indi, ekos and kstar.
-> redid all testing, but same results
- I also downloaded "gphoto2" but i don't know how to know if it is used by indi or not ... there is no list of a driver "gphoto2" in equipment list available at configuration
- It seems the software is not able to get the file from the camera, and the software stayed blocked at the end of exposure 1 and cannot start exposure 2.
I thought about a memory problem, so i created a large swapfile on the linux side (10Go !).
-> again doing all testing again, and nothing better and swapfile is not filled more than 5Mo
To be highlighted : Yesterday after swaping from SD to RAM it works once !! i thought it was OK, but i redid the same shooting a second time and it didn't work anymore .. i did the same manipulation once again : swapping from SD to RAM and shoot => no result
Also to be highlighted : I was able to make it work but changing from RAW shooting to JPG shooting ! ... but clearly i cannot work like that ... All seems pointing a problem because of a too big file to transport ... but a 40Mo RAW file is not that much !
I am trying to attach you Two log file of the ekos/indi : First one with the normal indi_canon driver, and second one with the gphoto driver. (with FITS and NATIVE testing on each one) At each end of exposure i received a "unknown event" error in the log then the driver crashed or stay blocked...
I hope some of you can get some ideas and could help me on that,
thank you very much to each of you for reading me and helping
