Long Story short … The QMI SDK Guide - Integration with Airvantage V. 1.19 states

Deploy to Raspberry Pi
6.1. Build
6.1.1. Configure toolchain
cd ~
git clone https://github.com/raspberrypi/tools.git
6.1.2. Compile QMI SDK
cd <SDK_ROOT_FOLDER>
make -C pkgs -f pkgs.mak complete -j CPU=rpi
6.1.3. Compile the AirVantage Connector
(cd SampleApps/AirVantageAgent; ./build_avagent.sh rpi)
6.2. Deploy
6.2.1. Copy SDK executables & AirVantage Connector
runtime
scp -r pkgs/qa/qatestrpi build/bin/rpi/slqssdk
SampleApps/AirVantageAgent/build.rpi/runtime pi:/tmp
6.2.2. Start the AirVantage Connector
ssh pi
cd /tmp
sudo ./slqssdk &
sudo ./runtime/start.sh

So… the result is this

Any clues or insights as to why it would be failing here?

Okay research said ln -s arm rpi in both bin and lib, got it to build now… however on the device itself im seeing this…
So im curious now… being we all know the docs are wrong in places and i dont have the source to libfwupdate and libdevicetree, am i facing maybe an EABIT version incompatibility ? EABI4 vs EABI5 on rasbian ? I was told this worked on Raspbian but dont see how its possible if it cant load libs properly

Can you specify the modem you are trying to test with Airvantage?

4

its a Raspberry PI Zero with a 7304 modem

5

I was hoping that you were using an MC7455, which has a built in Airvantage solution.
Unfortunately external/SDK Airvantage doesn’t really work with the MC73xx.
We had a proof of concept for the x86, but it was not too stable for commercial use.
We should probably pull it from the docs.

6

So being that the modem is an MC7304 its pretty much not worth the effort asking for the SDK sources for libfwupdate and libdevtree as your statement is that AirVantage wouldnt really suffice on this modem even if the libraries were built properly for the architecture? And yes I already have an NDA with sierra

7

Local FW upgrade is working well with the SDK or SDK lite.
But I do not recommend integrating the SDK’s AirVantage extension.
MC74xx has a build in reliable AirVantage engine.

8

not sure how one can claim local firmware upgrade is working well on arm 32bit… raspberry pi 0 when you cant even load libfwupdate or libdevtree on raspbian, the agent seem to load and run but if you look at the above error messages

pi@raspberrypi:/tmp sudo ./runtime/start.sh pi@raspberrypi:/tmp bin/slqs_fw_update: error while loading shared libraries: libfwupdate.so: cannot open shared object file: No such file or directory

i doont see how it could be working, which is why i inquired about getting sources to those two libraries so i could compile them natively

and well the MC7304 spoecs stated airvantage tested certified… so what gives… very confusing and frustrating

other ideas are MQTT paho against airvantage

9

If you just want to upgrade the FW on the local filesystem use SDK Lite.
It is a standalone utility : /SampleApps/lite-fw-download.
Actually I’d recommend SDK Lite over SLQSSDK for all projects because it is a library, much simpler to work with.
