Hi all,

I am trying to use the indi_gphoto_ccd driver under linux. On my laptop, it works, I can even acquire images in bulb mode using a usb-serial adapter with a handmade signal converter.

However, when I connect the Canon DSLR to my small arm box (not a raspberry pi, but a S912 box under armbian), I cannot acquire any images, i obtain the following error (logged through the client):
Error starting exposure

It is a shame because if I use the following gphoto command, I can acquire images on this platform:
gphoto2 --capture-image-and-download --filename "test.jpg"
The latter command works perfectly.

How can I debug this ?

Thank you in advance, this is one of the last problem I have to solve to get myself a proper beginner indi setup.

hi Dolguldur,

not have an answer to your question sorry. But as I'm using a Canon DSLR too, what is the benefit in using indi_gphoto_ccd instead of indi_canon_ccd?

Hey, thank you fenriques !
I think those are exactly the same unfortunately:

/indi/3rdparty/indi-gphoto/CMakeLists.txt:"exec_program(\"${CMAKE_COMMAND}\" ARGS -E create_symlink ${BIN_INSTALL_DIR}/indi_gphoto_ccd \$ENV{DESTDIR}${BIN_INSTALL_DIR}/indi_canon_ccd)\n

uh. you're right. Didn't ever notice that symbolic link in /usr/bin
lrwxrwxrwx 1 root root     15 Jul  9 18:58 indi_canon_ccd -> indi_gphoto_ccd
Thanks.

As weird as it may sound... testing with indi_canon_ccd now works as expected...
I don't really understand how this is possible, probably a switch somewhere in the code, I'll check that later. Now that I can acquire with the indi control panel, I'll check with Ekos, and then setup my python acquisition script.

There is difference, though it probably does not matter for most users. indi_canon_ccd supports multiple canon cameras as the same time, while indi_gphoto_ccd can open support one camera at a time.
