Yes, I leave the images on my Pi and then copy them over.

Bad news. After about 10 successful test runs with the Rock64, this evening it too failed while framing. Previously I had no issues for many minutes. Tonight, the 163M disconnected from Indi in 25s. So, the USB3 bus might not be as big of an issue as I thought.

knro, please let me know how I can help figure this out. I've played with the QHY SDK in the past, and I got a basic PNG imager built.

I'll try to provide more clarity. Here I have the QHY163M setup to focus on an artificial star in my office.


It goes for a while, but then stops capturing. You can see that 35 frames have passed since starting at 10:10:43, but it is now after 10:13. I then click Stop to halt the focus module, and I go to the Imaging module. I try a 1s preview image.

You can see that while the capture began at 10:13:38, it is now 10:15 and no image has been received. Checking to see if the camera is still connected...

... shows that the 163 (properly identified as c164) is still present according to lsusb. I then tell Ekos to disconnect, stop Indi, and restart Indi.

Unfortunately, Indi no longer finds the camera.

This is how the problem manifests for me. I don't know if it is similar or different for rankinstudio.

When my 163M drops from the RPi3, you have to unplug and replug the usb cable and relaunch Indi in order for Indi to see it again. I was having this problem fairly regularly with the Focus module, possibly because my manual focusing takes a while.

I wonder if a watchdog could be put in place? Something that could watch for a lost connection and then reinitialize?

Still, the 168 is a larger sensor, so it would be throwing more data over the bus. @knro, are you connected wirelessly to the RPi?

Regarding the Rock64, there is a thread here about that. So far, I have not encountered a disconnect. However, the available Linux distributions are not up to RPi standards. I’m working through a routing issue with having WiFi and eth0 at the same time. Also, full images transfer slower across the usb3 than RPi’s usb2, 10s vs 7s, but I’ll take that over instability. Another variable, since the Rock64 only has 3usb, I am using a powered hub. I hadn’t tried a powered hub on my RPi.

Does the disconnect problem happen on a laptop/PC with USB3 ports?
I think what you are experiencing is related to the high bandwidth of the camera. I too would have the 163M drop out on my Pi3, no matter what the USB speed setting. I don't see that problem when commented to my Linux PC through. Also, my (new) Rock64 which has USB 3 does not seem to drop the 163M (only have been testing for 2 days).

I tried a number of different ways, including "marco --no-composite --replace" and using MATE Tweak to try the interactions of the Marco WM, but I either get:
1. Icons on the desktop but graphical programs don't display properly (Firefox, Kstars)
2. No icons on the desktop, but Kstars and browsers render properly.
So, for now, I'm going with #2 and have created shortcuts to the apps and utilities in my Applications menu. Now to test out my cameras and see about wifi.

I can also connect a QHY5L-II-M and QHY163M at the same time. However, stability of the faster USB3 devices is questionable on the Raspberry Pi 3. My 163M likes to disconnect occasionally, and I suspect it is due to the high data transfer rate that the Pi cannot handle.

I’ll have to some more testing when I get home. While the command allowed for the desktop icons to show up, both Firefox and Chromium are having display problems. But... I didn’t test the browsers before trying the startup command.

Yeah, the distribution builds aren’t comparable to those for Raspberry Pi. All the builds appear to be “Community” instead of officially made by Pine. Maybe this is an opportunity for StellarRock.

2. The second big issue was that the icons on the desktop did not appear when the Marco compositor was running and it seemed like no matter what I did, they wouldn't appear. I tried a method suggested on this webpage however, and that seems to solve it:

ubuntu-mate.community/t/marco-compositor...ng-on-reboots/8499/3

The solution is to make this command one of your startup items:

marco --no-composite --replace

I now seem to have icons! Were you guys able to get icons on your desktop?

I got my Rock64 earlier this week, loaded xenial-mate-rock64-0.5.15-136-arm64.img, and I was pulling out my hair trying to figure out why icons weren't showing up on the Desktop. I started trying a bunch of different linux builds, but they all had other issues. I'll give it another try with your suggestions. Looks like the flash will get done right before I need to go to work.
Two things I have to do: 1) the ralink wifi adapter I bought doesn't have a prebuilt module, so I'll have to remember how to do that again. Fortunately, I have an older RTL8188 that seems to work although the range is poor. 2) the desktop manager or compositor was occasionally throwing errors and making the menubar inaccessible.

For speed purposes, I got a 32GB eMMC. Are you running off eMMC or SD?

I haven’t had trouble with my RPi3 and QHY5L-II-M. RPi2 would have trouble with too much data being sent through the bus (that was when I used iAstroHub). I only do 1s exposures on my 50x200 guidescope. How long are your exposures?
Now, the usb3 based QHY163M that I have will drop the connection, likely due to bus saturation again on the RPi3’s usb2.
I’m going to upgrade to a Rock64 and see if that helps my situation.

sywong2000 wrote: Hi Wim,
May I ask the fastest FPS (say certain resolution like 640x480) you can achieve on the rock64 usb3?
Thanks
Stephen

I’m curious about this too. While we’ll do long main exposures, we typically do short exposures for focusing. My QHY163M gets about 1 frame per 6.1s at full resolution on my RPi3. The 163M stuffs the USB2 bus and will sometimes drop off the bus, so it would be nice to know the frame rate on the Rock64 (even if it is for other cameras).

Jeff Wilson replied to the topic 'Pi3 and indi Server' in the forum. 2 weeks ago

Chris,
The indi server is not automatically started, but it wouldn't take too much work to make that happen. Rob's script installer for the RPi places a desktop shortcut for starting the server. Placing scripts into /etc/rc.local will allow them to start on boot. I don't usually like this approach since it can be a bit of pain to cleanly shutdown a script.

Add a file called ~/.config/kdeglobals

and put in it:
[Icons]
Theme=breeze

If this works I can easily add that to the setup script. I found the answer here:
www.google.com/url?q=https://forum.kde.o...yC2IJbCFjNA2023L86qg


This worked for me. I just installed kstars on my Linux PC, and the icons were missing. (I had a few difficulties with an existing kstars causing dependency issues) I recalled this thread, and that kdeglobals file got the icons appearing.

Rob, you were right! (It's always nice to hear, right?)
So, I bought a lightning-to-RJ45 adapter, specifically the following:
www.amazon.com/gp/product/B0725PYSP3/ref...01_s00?ie=UTF8&psc=1
I then configured my eth0 for a static IP that matches the IP address my router normally gives it. For those that don't know how to do this, here is a YouTube video:
https://www.youtube.com/watch?v=6qsyPTDU2aYhttps://www.youtube.com/watch?v=6qsyPTDU2aY
Once the static IP address is set, plug in the lightning-to-RJ45 dongle to your iOS device. Open Settings. In the networking menu, below WiFI, you should see a Ethernet option.


Turn Off Wifi on the iOS device. Select the Interface, and configure it for Manual IPV4 Address, using the same subnet mask. My Pi was setup for a static 10.0.1.14, so I made my iPad Mini have an address of 10.0.1.42.


I fired up Cathode (a great terminal app), and I was able to connect to the Pi at the static address. I then ran VNC Viewer on my iPad Mini, and I was able to view the Pi's desktop. Cool!

Now the real test. From my iPad I launched the "Start Ekos Field Wifi", unplugged the RJ45 dongle, turned my iPad's WiFi back on, and there was the Ekos_FieldWifi access point. I had already configured this connection with a password, so I was able to connect. Running VNC Viewer allows me to connect to the Pi from here too.

I am looking forward to testing this in the field... when the clouds clear out.... It is great to have a headed headless Raspberry Pi. Maybe I'll rename it dullahan.
