cam does not seem to be alive issue

@Alex-Kushleyev
Thank you for the help, I have tried a different cable and it didn't work either, plus this flex is working when I am using it on a different voxl2 -
@giladWDS , it seems that there is a HW issue on the VOXL2 side with J7U. Specifically, any camera connected to it is not detected, which could be either i2c or power issue.
Is it an option for you to connect the AR0144 camera to J8L ?
In order to figure the problem the board would most likely need to be sent back to us for inspection.

Hi, after I had to work on other projects I have finally come back to this and I managed to make the voxl read all cameras when I moved the tracking camera to j8-lower.
now the issue I'm facing is with a frame rate reduction.
it seems that whenever I try to change the frame rate of one of the high-res cameras the server crashes.
this is the server log:Oct 27 12:35:13 root systemd[1]: Started voxl-camera-server.

@giladWDS I did a quick test on my set up with IMX214 connected, and it has no issue with 5 or 10 fps with largest resolution 4208x3120 preview. I am pretty sure i tested slower (than 30) FPS on IMX412 before. Can you please try some other FPS (15, 20, 25) and see if you can find any pattern of cases that do not work? Also what if you disable one of the cameras. I am just trying to think what can cause this..
I will get a chance to test with two IMX412 tomorrow.

@Alex-Kushleyev
I have tested different layouts with different cameras disabled and it didn't work either.
for some reason, the voxl won't accept any other frame rate in the config file other than 30. -
@giladWDS , this is strange. I can set IMX412 to any rate I want, however I am using different sensormodule files - can you please try to use ones from :
/usr/share/modalai/chi-cdk/imx412-fpv/com.qti.sensormodule.imx412_fpv_0.bin
/usr/share/modalai/chi-cdk/imx412-fpv/com.qti.sensormodule.imx412_fpv_2.bininstead of com.qti.sensormodule.imx412_0.bin com.qti.sensormodule.imx412_2.bin (remove or rename these first).
please note that it is possible that the "fpv" version of the sensormodules may not have the full resolution in your older system image (latest ones do), which you can check using
voxl-camera-server -l, but i think it should..Edit: i also tried the modules you used, and works fine for me (i tested using a single camera)
One more thing to try is to lock camera server to faster cpu cores, which can be done in the following way from command line (you should stop the camera server service first):
taskset --cpu-list 4-7 voxl-camera-serverIf this still does not work, please provide output of dmesg and logcat saved to separate files, so i can potentially see the reason for the crash. Thanks! (well, even if one of the solutions works, i would still be curious what error you were getting before!)

@Alex-Kushleyev
It would take some time to do this since I found a workaround compiling the camera server from source with a small fix:
I changed the hal3_camera_mgr.cpp
from:
int32_t frame_rate_rate[] = {fps,fps};
into:
int32_t frame_rate_rate[] = {1,30};
I know this is hacky and will probably bite me if I try to put higher fps for low fps cameras like a tof or something but it works for now.
I will get back to it and update. -
@giladWDS , thanks for the udpate!
I believe we had to use the following line in order to enable fps higher than 30 (or higher than 60, i forget), otherwise the high fps was not working.
int32_t frame_rate_rate[] = {fps,fps};We will keep this in mind, however I am not able to reproduce your issues, so we'll just keep this conversation open.

@Alex-Kushleyev hi
I just stumbled upon the same bug with our voxl-flight-deck module that also refuses to downscale the fps. -
@giladWDS , can you please provide minimal instructions to reproduce on voxl2? I can try it from sdk install, then configure cameras, modify config to lower fps and test.
Regarding flight deck, is it voxl2 flight deck or voxl1?

Perhaps the solution will be to check if desired fps is less than 30, then use the different fps range, but I would like to reproduce first, since i am able to set the fps correctly below 30 as is.
