Hi
I´m trying to get Virtualhere to run on Boot at my RaspberryPi Zero
I´m installing using the scrip at https://github.com/virtualhere/script
An as far I can understand from the FAQ Virtualhere should run at boot if it was installed by the script but it dosen´t.
I´m running a Pi Zero with Zero4U usb HAT. Connection is a 4G LTE USB modem and it works fine to ssh into the machine but when i do ps -A there is no vhusbdarmpi there.
Any sugestions?
.
What does
systemctl status virtualhere
say?

Its very unusual to have a segfault in virtualhere. Usually its some kernel bug.
Could you try the vhusbdarm binary like this
1. First uninstall the current server like this
curl https://raw.githubusercontent.com/virtualhere/script/main/uninstall_server | sudo sh
2. Then can you install the generic server like this
curl https://raw.githubusercontent.com/virtualhere/script/main/install_server | sudo sh
See if that still crashes when you reboot the pi0w.
If it still crashes can you run the server manually like this
sudo /usr/local/sbin/vhusbdarm
and see if it runs
Same fault as before whith
Same fault as before whith Generic Server

And it runs fine on
sudo /usr/local/sbin/vhusbdarm
.
Ok so if it runs fine manually after its all booted then it must be some boot service it is missing.
Could you edit the /etc/systemd/system/virtualhere.service and change the After line and add a line after that like this
After=network-online.target
Wants=network-online.target
Then save the service file and reload like this
systemctl daemon-reload
systemctl enable virtualhere.service
Then power off/on your pi0w and see if it starts ok now
Same problem now.

Im re- testing raspbian on my pi0w but i cant seem to find a bootable image. The one from the raspberrypi website doesnt work with the pi0w. The pi0w wont boot and nothing in the serial console either.
Where did you download your raspbian image from for the pi0w?
I ran the raspberry pi imager

I don´t have p0w i only have p0

OK that is the issue then. VirtualHere needs to have a network interface up before it starts. It wont start with no network interface at all.
So you need to run virtualhere after your modem is initialized. You cannot run that boot script, you need to write a custom script to do that. I dont know much about your modem other than you need to run a script to start virtualhere if it has a network interface in /sys/class/net (not including lo)
I use a USB ethernet device
I use a USB ethernet device but mabey that is initilized to slow to then?
I´m using that during my config and testing. Later the point is that the Pi, a mobile broadband and a "SportIdent Device" are going to work as a Online Readout for Orienteering courses.
.
Yes virtualhere needs to start after at least one interface has been created by the linux kernel during boot. It doesnt need to actually connect to a network. I just needs to exist in /sys/class/net
Normally a linux box has at least one network interface that the kernel boots and thats why virtualhere has a "After=network.target" in the script. However there is no network interface built-into the board so virtualhere cant start.
