Illegal instruction (core dumped)

[ilysec]

Hi there,

I am trying to run

~/.local/lib/python3.10/site-packages/mavsdk/bin/mavsdk_server serial:///dev/serial0:921600

And I get the following result:

[09:38:36|Info ] MAVSDK version: v2.2.0 (mavsdk_impl.cpp:26)

I tried reinstalling grpcio as mentioneed in #345:

pip3 uninstall grpcio
sudo apt-get install python3-grpcio

However, nothing seems to solve the "Illegal Instruction" problem.

Ok. This is on what hardware and what OS?
