QHY 5L II connection problem. Again 2 months 6 days ago #25246

It seems that lately QHY are giving issues. Searched the forum but didn't find anything matching my issue.
I tried to update, upgrade, dist-upgrade and reinstall indi-qhy but nothing seems to work. This is the dump of:
indiserver -vvv indi_qhy_ccd
....
2018-04-18T22:18:29: Driver indi_qhy_ccd: pid=2615 rfd=0 wfd=6 efd=7
2018-04-18T22:18:29: Driver indi_qhy_ccd: sending msg copy 1 nq 1:
<getProperties version='1.7'/>

2018-04-18T22:18:29: Driver indi_qhy_ccd: indi_qhy_ccd: error while loading shared libraries: libqhyccd.so.1: cannot map zero-fill pages
2018-04-18T22:18:29: Driver indi_qhy_ccd: stderr EOF
2018-04-18T22:18:29: Driver indi_qhy_ccd: Terminated after #10 restarts.
2018-04-18T22:18:29: good bye

Have any idea?

Even a full reinstall of indi / ekos doesn't work.
Found in the forum that 2 months ago qhy changed the name of their library from libqhy to libqhyccd but this was fixed immediately after by Jasem.
I'm running Ubuntu 16.04 mate on a rpi3.
Too bad this happens when the weather is nice after months of clouds and snow....

QHY 5L II connection problem. Again 2 months 4 days ago #25297

after further investigation, seems that the libqhyccd version number doesn't match.
The error I get is about version 1:
error while loading shared libraries: libqhyccd.so.1
While in CMakeList file both libqhy version and soversion has been update to the new SDK more than 20 days ago:
set(LIBQHY_VERSION "2.0.0")
set(LIBQHY_SOVERSION "2")

EDITED: wrong guessing: libqhyccd.so.1 is just a symbolic link to 2.0.0

QHY 5L II connection problem. Again 2 months 4 days ago #25298

found a workaround, assuming you have RPI3:
/usr/lib/arm-linux-gnueabihf/libqhyccd.so.2.0.0
could be copied or renamed to:
/usr/lib/arm-linux-gnueabihf/libqhyccd.so.2.0.3
...or, better, just wait for the fix that Jasem did 12 hours ago but not yet available as update.

Check if the Nightly PPA solves the issue or it's the same there?

The nightly version gives me the same error:

Have you installed libqhy or indi-qhy yourself before? You have something on your system that interferes with this. Is this on RPI3 or x86-64 system?

EDIT: Ok I know why. For some reason, the QHY SDK is reserving TOO much memory (~780 MB) but its actual use is very little, but this is leading to errors in memory use. This is not a problem on StellarMate due to memory compression but on a regular RPI3 it would be a problem. I'll try to find out why it is reserving so much memory.

I'm using Ubuntu Mate 16.04 on RPI3 (same as Fenriques posted). Everything was a fresh install from your ppa. For the nightly I simply updated only the qhy package. Thanks for checking.

@bowmangotti: in the meantime, as Jasem implicity suggested, using compressed memory works fine.
Use this script: github.com/novaspirit/rpi_zram
Check the result with the command 'free'

QHY 5L II connection problem. Again 2 months 12 hours ago #25439

Hi,

I have attempted this solution and the problem wasn't resolved for my QHY5-M. It is showing the "Exposure Timeout" error since the update released 08/04/2018.
I have a QHY5-L-ii-c that seems to work without any failures but I would rather not guide using the colour cam. Any suggestions?

Your issue seems not related to the one discussed here. Whenever I have a timeout error I power off/on the camera and restart indi. Usually it is sufficient to fix the issue.
Yesterday a new release was available, have you tried to update?
If this won't fix it I suggest you post here your log file.
