ChirpStack Gateway OS on RPI Zero

[sergi_jini]

Hello,

I am experimenting with ChirpStack Gateway OS mesh and want to try it with RPI Zero.

I got the image from here Raspberry Pi Zero W image (base image).

All works fine, I can login the Luci GUI and configure all the parameters, except of the Gateway Mesh tab, where I see below error. As I understand it is more related with OpenWRT part rather than Chirpstack.

Anyone having same problem?
I have several RPI Zeros laying around so I thought it would be a good idea to utilize them as relay Gateway hosts instead of RPI CM4

Note this happens on Base image only, Full image is ok (but I prefer not to have Chirpstack server on the Gateway itself)

Does your system have the ubus?

Try this, if not:
ubus
$ git clone git://git.openwrt.org/project/ubus.git
$ cd ubus
$ mkdir build
$ cmake …
$ make
$ sudo make install

thanks for the hints @LouneCode. I’m bit slow on responses.
Yes let me check and feedback

I think I might have found the problem. I was looking at the Chirpstack Gateway OS repo, and noticed a difference between the bcm2708 and bcm2709 makefiles.

In the .config for the bcm2709, you’ll see that:

CONFIG_PACKAGE_chirpstack-gateway-mesh=y

but in the .config for bcm2708, it’s:

# CONFIG_PACKAGE_chirpstack-gateway-mesh is not set

Does anyone know if this is a conscious decision for some compatibility reason to do with really old raspberry pis? Or is this just an omission that no one’s encountered yet?

Just to close the loop on this for anyone searching in the future, I opened a github issue, and a fix should be included in the next release of the gateway os.

I see it on GIT it is solved and closed already? Thanks @ambrotos for pointing out the potential root cause.
Will wait for the next OS release to test it.
