Problem using Upm library in Python

[JHrib]

Hello, everyone.

I am trying to use the upm library in Python on Intel Galileo Gen 2. More specifically I want to read data from ADS1115. The problem is that whenever I want to import upm, the Python returns me an error: "No module named upm". This means that my image does not have upm installed and for some reason, I can't install it.

I try to install upm using:

opkg install upm

results in error:

opkg_install_cmd: Cannot install package upm

I attached detail error. What is a workaround to install upm lib which will work in Python? I would like to avoid building the package as I have to install for few (5) devices.

My OS version:

3.8.7-yocto-standard

ID=iot-devkit

NAME=iot-devkit (Intel IoT Development Kit)

VERSION=1.5 (panda)

I would be willing to change OS for a different version if that would help me use upm.

Kind regards

Hi JernejH,

I've not installed/used upm-python, but I found some references which may be useful:

https://software.intel.com/en-us/upm-sdk IoT UPM SDK - Overview | Intel® Software

https://iotdk.intel.com/docs/master/upm/installing.html upm: Installing UPM

https://github.com/intel-iot-devkit/upm/blob/master/docs/installing.md upm/installing.md at master · intel-iot-devkit/upm · GitHub

HTH,

Fernando.

Hi, Fernando.

Thank you for your answer.

I tried this command:

bash echo "src intel-iotdk https://iotdk.intel.com/repos/3.5/intelgalactic/opkg/i586/" > /etc/opkg/intel-iotdk.conf opkg update opkg upgrade mraa upm

returns me this error:

/bin/echo: /bin/echo: cannot execute binary file

Any idea, how to fix this error?

Kind regards

Jernej

Maybe you did not include all the ' and/or ` described at the page/url... try the one-step-by-line version, which I think is that described at https://github.com/intel-iot-devkit/upm/blob/master/docs/installing.md upm/installing.md at master · intel-iot-devkit/upm · GitHub:

echo "src intel-iotdk https://iotdk.intel.com/repos/3.5/intelgalactic/opkg/i586/" > /etc/opkg/intel-iotdk.conf

opkg update

opkg upgrade mraa upm

HTH,

Fernando.

PS: always try all the possibilities you find in different sites in case some of them do not work.

Hi, Fernando.

I solved my problem. The solution was using different OS image I got https://iotdk.intel.com/images/3.5/ here. I guess I was using wrong Intel Galileo image or something. With the new image opkg install upm works like a charm.

Kind regards
