Joy_Detection_Service Fails to start

[Espanta]

Hi, After following several thread here about camera issue, I found that there is a dependency which fails when trying to load Joy_Detection_service. Here is more details:

• I have Camera V2.1 but it does not work. I ran
• I looked at all cables and they are fully matched with the details on the guides

sudo systemctl status joy_detection_demo.service and below is errors I get

Dependency failed for AIY Joy Detection Demo. Feb 02 11:46:06 raspberrypi systemd[1]: joy_detection_demo.service: Job joy_detection_demo.service/start failed with result 'dependency'.

sudo systemctl start joy_detection_demo.service

Appreciate any help!

I did flash the SD card again and this time, I did not allow update and things are now working. Maybe you would like to consider this as an opportunity to refine guide.

Thanks for reporting this, yes, there are some issues, we'll try to update the guide soon. Let's keep this issue open for now.

I ran into the same issue when I set up my Vision V2 a few days ago - the joy demo initially worked, and after updating, it stopped working. I'm seeing the same errors reported above.

I see that the 2018-11-16 image has kernel 4.14.71, with a driver from staging/myriad: /lib/modules # find | grep vision ./4.14.71-v7+/kernel/drivers/staging/myriad/aiy-vision.ko ./4.14.71-v7+/kernel/drivers/media/usb/usbvision ./4.14.71-v7+/kernel/drivers/media/usb/usbvision/usbvision.ko ./4.14.71+/kernel/drivers/staging/myriad/aiy-vision.ko ./4.14.71+/kernel/drivers/media/usb/usbvision ./4.14.71+/kernel/drivers/media/usb/usbvision/usbvision.ko

The current raspbian release installs kernel 4.14.98, and lacks the aiy-vision module from staging/myriad: /lib/modules # find | grep vision ./4.14.98-v7+/kernel/drivers/media/usb/usbvision ./4.14.98-v7+/kernel/drivers/media/usb/usbvision/usbvision.ko ./4.14.98+/kernel/drivers/media/usb/usbvision ./4.14.98+/kernel/drivers/media/usb/usbvision/usbvision.ko

Perhaps it would be best to not pull in kernel updates until we have a reliable way to rebuild the affected module against a new kernel (would dkms work here? I haven't played with the RasPi's kernel much).

edit Whoops, there's a dkms package already installed for this. I'm not sure why it's not being run already - I'll try triggering a manual build.

It looks like dkms did the trick here. For some reason, dkms didn't have any of the dkms modules set up - I had to dkms add each individual package (aiy/1.1, aiy-vision/1.1, aiy-voicebonnect-soundcard/1.0 leds-ktd202x/1.1, pwm-soft/1.1), then dkms autoinstall to build and install everything. A quick reboot later, and this works on the new kernel!
