Hi Guido,

I am back and tried your advice. Short story: errors appear in the syslog because /sbin/fxload does not exist on my RPi! I am puzzled by this. If firmware has always been loaded, how did my system work if fxload does not exist? Anyway, see below for details.

Here's the output from journalctl -f when I plug in the camera:

Jun 16 18:42:56 indi-pi systemd-udevd[709]: Process '/sbin/fxload -t fx2 -I /lib/firmware/qhy/QHY5II.HEX -D ' failed with exit code 2.

Of all the files mentioned in the command line, it's /sbin/fxload that doesn't exist. I searched for "ubuntu fxload" and found a link back to INDI (Raspberry Pi) , which says this:Perhaps this is the issue? (BTW, I don't understand what it means)

This is the first time I built INDI from the git repo. Before this, I downloaded compiled packages from that same URL. Things magically worked, but if I make it myself, perhaps there are other prerequisites I need?

Thanks,

Charles

So I tried anyway and installed fxload. It doesn't seem to work. Below is the output from journalctl -f, and attached is the output from indiserver -v indi_qhy_ccd.

It does seem to work with Ekos briefly (using the streaming option in the config screen). But then it becomes unresponsive and I quit kstars to stop Ekos. I think I'll be uninstalling fxload.

Hi Charles,

Good! At least some progress.

FX3 refers to the Cypress USB interface chip used in these cameras. The FX2 is for USB2 and FX3 for USB3. The QHY5 family only uses FX2.

In the first of your last two posts you see two lines with failing fxload. The second post only shows the second failing fxload line. What is strange is that the device address after "-D" is missing. I guess you have two matching udev rules that trigger fxload. The first one was successful now that you have an actual fxload, therefore the camera briefly worked in INDI.
So you might look for udev rules files in /etc/udev/rules.d and/lib/udev/rules.d and delete the wrong one. Hard to say which one. You can rename a rule file and append ".disabled" (any suffix would do) to try out.

That the camera stopped working in INDI is unrelated to fxload. I have had issues with streaming before, also with a non-QHYCCD camera. I do not use it anymore. With my ZWO ASI 224mc I also have to switch the camera to a different mode (LUMA instead of RGB), which is annoying. I use the focuser tab instead, which can loop single image acquisitions.

Well anyway, it does work now. lsusb shows the product id is now "0921", and Ekos recognizes the device and can loop in guiding to get images. No idea why it's working.

I don't know why that error shows up in the logs indicating that fxload failed. The argument for -D is supposed to be "$env{DEVNAME}", and the fact that it's an empty string certainly seems wrong since every rule in /lib/udev/rules.d/85-qhyccd.rules has the same command argument, which makes a person think it's important...

I grep'd all .rules files on the system and the only one specifying vendor ID "1618" and product ID "0920" is the QHYCCD ruleset under /lib.

So, something else must be loading the firmware, or otherwise hooking the device up? Mystery to me...

Have you also checked /etc/udev/rules.d? Any rules there that match 1618:0920?
udev does not stop with the first matching rule it finds. It executes all of them.
I suspect it finds two rules: one with the error and one successfully loading the firmware.

Hello Oduig,

After looking at several non related issues, I have learned a few things about rules and Ubuntu-Mate. As for the QHYCCD brand of devices, I think I will create a distinct QHY5L-II rule. This prevent the blow out of any KSTARS rule overwrites.

The rules for QHYCCD are INDI-QHYCCDcamera.rule and INDI- QHYCCD.rule. A # is a comment field. The QHYCCD rule has many lines commented out. After reviewing the models, 1618:0921 is not listed. 1618:0920 is listed.

1618:0941 is the PoleMaster. 1618:0940 has a rule. None exist for 1618:0941.

If wildcard is used, then like families of devices would be working. I used a wildcard in getting another USB device to work. That was assigning a TTY port.

I added rules to the default QHYCCD rule files for the missing products that I have. Only one problem exists. The fxload and the -D (devpath) is pretty important. The OS refuses to load QHY5II.hex. This is fx3load being called out.

I will create a custom QHYCCD rule for the two newer devices not supported yet. This should cover me. I would like to know why the -D option is required for UBUNTU- MATE. Usbfs is an old distro of linux. All other QHYCCD models have -D blank.

I grep'd through the rules under /etc/udev/rules.d. There are only 3-4 files there, one of which I put there to assign fixed serial port names to my focuser and telescope.

I did a "sudo find / -name '*.rules' -print" to make sure there weren't unexpected places where rules files were lurking. This correctly found all the rules files under /etc/udev and /lib/udev, as well as under the INDI git repo clone, and no other places.

I've reading about the "udevadm monitor" command this morning. Might this be useful to seeing what's going on when the camera is plugged in? "udevadm test" might be useful, too...

Hello CRW4096,

Yes. Udevadmin looks like a good place to find DEVPATH. The device path is needed with the rules. This tool is the way to get it.

Hello,

Success! I have both QHY5L-II and PoleMaster recognized by EKOS. I created custom rules from 85-QHYCCD.RULES and 85-QHY-CAMERAS.RULES. I preserved the original files in a specific folder. I updated the rules and rebooted the PI. EKOS picked both devices up using Device Manager.

What are the contents of the 2nd file?

@AradoSKYindi:
Where are the INDI-QHYCCDcamera.rule and INDI- QHYCCD.rule coming from? The original INDI 3rdparty drivers come with a QHYCCD rule file called "85-qhyccd.rules".
In this file both pairs 1618:0920 and 1618:0921 can be found. For the first pair the firmware is loaded with the help of "fxload". Then the QHYCCD device renumerates and comes back as 1618:0921, which triggers the second rule which just sets the permission to read/write for everybody.
Same holds for 1618:0940 and 1618:0941.

Ideally there should not be any tinkering necessary with the rules files. I was suspecting that maybe another package or manual editing interfered with the original rules files.

Also a -D without an argument does not make sense. Something must be wrong there.

@AradoSKYindi:
You have both 85-QHYCCD.RULES and 85-QHY-CAMERAS.RULES?
Maybe one is a leftover from an older install or different package.

Ah, I see, Jasem also wonders what is in the second file...
