I was just trying to connect to my QHY5-II in EKOS, but the light
On the indi panel staying red.

Also no luck connecting to the camera on RPI with indiserver.
Cant find any errors on the terminal output.

The Camera is working on the same PC with lin-guider.

Any suggestions what i can check?

I don't believe the QHY5-II is supported by the INDI driver. There has been many discussion on QHY support in INDI before if you search the forum, currently no one is working on that unless someone steps in. Also, QHY needs to really work on a creating a proper API for the CCDs, not the hackfest that is currently going on.

There is an unofficial driver for QHY5-II, but I don't know if it works well. bitbucket.org/peppertarts/indi-qhy5ii

Sad to hear the qhy_ccd is not supporting the alccd5L-II camera.
Maybe there will be a official driver later on.
I will try the unofficial driver and report here.
Wish me luck

I did try co compile the unofficial driver mentioned by lupinix.
No luck with that. Packet "lfxload" is not known an i get errors that
libindi is not found. I will try to contact the author.
If that is not working I am stuck. Either have to wait for an official driver,
take another guiding cam or use lin_guider beside of indiserver on
my RPI.

There is no lfxload package, it's a typo. I just compiled it fine, try this:

Yes you are right.
I left the library out and was able to compile the driver on the RPI.
First the camera did not respond. I did notice the red light at the back of the
camera was off. But with a qhy_ccd_test it came on. No idea why that is.
Then i could connect through EKOS with indiserver indi_qhy5ii_ccd.
I can capture and transfer pictures but that is still rather slow.
It will take about 15 sec. to take and transfer 1 picture. That should be to
slow for autoguiding.
Maybe the driver supports ROI somehow to reduce the traffic.

I had the QHY5L-II, couldn't get it to work under Linux correctly, and there is no INDI driver for it. Ended up selling it.

I think other QHY Linux users should follow suit. That should send a message to QHY.

Don't get me wrong, this little camera is great under Windows. Pictures are good if you use darks.
I do know there is some sort of alpha driver for it for Linux, tried it but too many bugs for my liking to be able to use it everyday.

I'm going for an Atik 314L+

Hello Folks,
I am off for holidays in Kroatia for two weeks now.
Right after that with a cloudless night I will try the whole setup
Including the driver for my QHY5L-II- c.
If somebody is interested in the results I will report here.

Then the firmware is not loaded… Maybe an issue with the udev rules?
RPi can be tricky… We have two QHY5-based CCDs (not QHY5-II), both work fine on "normal" computers, but one doesn't work with RPi… (produces difficult pictures) They only differ in the USB PID. I'm looking for a more powerful alternative now, maybe Banana Pi or Cubietruck (need Gbit LAN because we control our stuff entirely over LAN from the office), I hope the second QHY5 works then too
