Siemens Simatic IOT2040

Product support balenaOS
1

Hello,
after being able to deploy some services on a Raspberry Pi, a balenaFin and a RevPi Core 3, now I’m trying to do the same on a Siemens Simatic IOT2040 but… it doesn’t work. The service keeps restarting, and I can’t get even a simple output.

Is anyone being able to successfully run something on this platform?

Cheers,
Matteo

Hi there
Could you share some additional information here? What’s your OS version and the errors encountered? Also, could you share a minimum Dockerfile/compose file we could use for reproducing that behavior? Thanks!

Hi Michael,
I’m running Resin OS 2.12.7+rev2 and all I can see is that the service is restarting over and over.

Hello @mcomisso , can you please allow support access for this device and provide us its uuid or dashboard link?

Hello Alexis,
UUID 328601c294669458351f678aa8afef89 and access granted!

Thanks,
Matteo

Thanks, I’m doing some tests on the device.

Ok, it turns out Debian does not run on Intel quark processors, see https://www.debian.org/releases/jessie/i386/ch02s01.html.en .
And this is the processor iot2000 devices use.
Sorry this took some time :slight_smile:
I’ve pinged our team to remove the Debian base images for iot2000.
You can use Alpine base images instead (I’ve tested one, it works) but you’ll need to adapt your Dockerfile (replace apt-get with apk, etc…).

Hi Alexis,
thank you very much for your support!

I’ll try with Alpine but I’m quite sure that this time it will work as expected.

I suggest your team to also update the “Getting started” page for this device (https://www.balena.io/docs/learn/getting-started/iot2000/nodejs/#adding-your-first-device) since it points to the “simple-server-node” project that uses the Debian stretch image. This is mainly why I ended on using that distro…

Thanks again!

Matteo
