RE: How to Update?
Wow I take that back, I just haven't used this PI3 in so long, the base image had the camera disabled. Both USB and Onboard camera work perfectly it seems in the latest build. Nice work dude!
RE: How to Update?
Awesome, glad to hear that. Let me know if any unexpected bugs crop up.
RE:
When I initially start the device (the pi) everything loads, and the info on the PICamera is shown. It grabs an initial image, and it displays it, it shows BOTH my USB cam and my PiCam. But then some time immediately after, it disconnects the Picam, the USB stays running/good.
I see the following error all though the syslog, but its not super helpful. Any thoughts on what might be helpful to troubleshoot? Thanks!

RE: How to Update?
Just as a heads up, I've tried searching the syslog for anything more helpful and haven't seen anything yet that indicates an initial error/issue.
RE: How to Update?
Ah, sorry, missed the first message, hm, somehow it gets stuck while taking a photo. I should have inserted an interesting logger trigger when this happens. Will make a branch that does this so we can look where did it get stuck.
A stuck camera should get auto re-connected in the master, does that succeed?
RE: How to Update?
After updating from RC1, I get this error while starting,

Any help?
RE: How to Update?
You must have updated from the repo without re-flashing. Please don't do that for this bump. They switched over to libcamera and we added TurboJPEG as a dependency. You probably don't have it installed
RE: How to Update?
No, it never recovers. Just constantly tries to take a pic with the PICamera, and can't, times out, retries.
I should note I've tried a Variety of ways to BREAK this, and so far, everything is working really well. You can hot swap cameras in and out, and they just get picked up. Its slick.
One thing that I'm working to do, is create a Nozzle cam, and a bed cam. Idk how many other people are going to use a setup like that, and not asking for anything special, just know that that is my use case 🙂 PiCamera for the Bed cam, and a USB camera for the close up nozzle cam.
RE:
You say you've tried a variety ways to break this. Do you mean USB cameras? The PiCamera hardly takes one photo regardless what you do. Right?
I have created a branch called diagnose-stuck-cameras in SDK and PrusaLink. If you instal these, any time the camera is determined to be stuck, it should output a ~300-500 lines of output including the stack traces of all threads. I'm interested in the stack trace of the thread(s) named Photographer

RE: How to Update?
Where is this logged to? Not seeing it in syslog...
RE:
Would you consider hopping into the discord server for instant messaging stuff? https://discord.gg/ntFX3wk
It should be in the syslog. If it's not i'm suspecting either the install not working, or maybe i screwed up somewhere.
Did you do
git fetch git checkout diagnose-stuck-cameras [sudo ]pip install .
for both the SDK and Link?
RE: How to Update?
Found the picamera problem in the master, if anyone else is looking at this, it fixed in a branch diagnose-stuck-cameras and soon will be in master
RE: How to Update?
I am stuck with a loop of downloading the .ini file, where do I upload it?
RE: How to Update?
Okay, this thread is getting very long and off topic. I'll create a new one for @bendrumin - https://forum.prusa3d.com/forum/postid/637611/
RE: How to Update?
Thank you 😊
RE: How to Update?
If it can help someone else... I have upgraded from 0.7.0 rc1 ro 0.7.0 rc3 with:
prusalink stop sudo apt-get update sudo apt-get upgrade sudo apt install git python3-pip pigpio libcap-dev libmagic1 libturbojpeg0 libatlas-base-dev pip3 install -U https://[email protected]/prusa3d/Prusa-Connect-SDK-Printer/archive/refs/tags/0.7.0rc3.tar.gz pip3 install -U https://[email protected]/prusa3d/Prusa-Link/archive/refs/tags/0.7.0rc3.tar.gz prusalink start
I am now trying to make it work with Home Assistant but I get an error.
RE: How to Update?
So how IS it actually done via SSH?
RE: How to Update?
Thanks @Mathieu.
RE: How to Update?
Just a reminder, going from 0.6.x to 0.7.0 uing this will not make your picameras work. Everything else hopefully will. Flash the rc3 image to have that work
