Fail to update udev rules


#1

Hi

Trying to setup the Movidius NCSDK 2 API on resin io through a local push. Installation is going well until the install script tries to reload udev rules. This is the part of the script that fails

# Update udev rules
echo "Updating udev rules..."
$SUDO_PREFIX cp $SDK_DIR/udev/97-usbboot.rules /etc/udev/rules.d/
RC=0 
$SUDO_PREFIX udevadm control --reload-rules || RC=$?
if [ $RC -ne 0 ] ; then
    echo "Warning udevadm control --reload-rules reported an return code = ${RC}"
fi
RC=0 
$SUDO_PREFIX udevadm trigger || RC=$?
if [ $RC -ne 0 ] ; then
    echo "Warning udevadm trigger return code = ${RC}"
fi

This is the output I get

Successfully installed mvnc-2.5.0.2

I am getting a return code 2 not sure what this means. Anyone ran into something similar?

@bpecheux I actually built a little test project with the movidius and the RPI3, you can check it out here: https://github.com/resin-io-playground/movidius-rpi3-demo . I actually put together a base image with everything preinstalled for this project. You can see the repo for that here: https://github.com/resin-io-playground/movidius-rpi3-baseimage

Thanks Shaun

I had seen the image before but I was trying to built using the official github repo https://github.com/movidius/ncsdk which appears to be offline right since 08/08/2018. I will give it a try. I noticed that you are using your own fork of the ncsdk. Did you make changes to the Makefile?

Yeah i messed around with the install script here because resin.io base images identified as debian rather than raspbian, but I actually think with the latest built image that might not be the case anymore, so it might not actually be needed.

@shaunmulligan Ok I gave it a try and got a bit farther this time but not quite there yet. I used the movidius base image and I added the following lines at the end of dockerfile (after run pip3 install imutils …) to check if ncsdk was working by running one of the ncsdk hello world example.

WORKDIR /ncsdk/examples/apps/hello_ncs_py

CMD ["python3", "hello_ncs.py"]

and built it on my mac and deployed locally to a raspberry pi 3 model B with a movidius usb key plugged in running Resin OS 2.15.1+rev1 development (supervisor 7.16.6). I used the following command to push over wifi:

sudo resin local push 2d6ae06.local -s .

This is what I got the first time I ran it

No luck. Does not look like the code is able to see the movidius key from the container. Here is what I got the second time I ran it.

Error - Could not open NCS device.

This time the movidius key appear to be stalled may be because it was not closed properly by the previously run and the ncsdk is attempting to reset it unsuccessfully.

Running lsusb on the host gave me this

root@2d6ae06:~# lsusb
Bus 001 Device 057: ID 03e7:f63b Intel

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Am I missing something on the resin os side? Do I need to enable something on the OS for the movidius key to be “seen”. Looks to me like I am back to where I was with the custom udev rules in the ncsdk install not working on the container.

Thanks
