In the meantime, if you get the above error, you can use the version of wiringPi already available on the system (if it is installed) by typing the following command.
sudo mv /opt/freelss-1-26/lib/libwiringPi.so /opt/freelss-1-26/lib/libwiringPi.so.bak
If you continue to have problems, you can run the following command to use only the system installed libraries as opposed to those packaged with FreeLSS.
sudo mv /opt/freelss-1-26/lib /opt/freelss-1-26/lib.bak

Uriah,

Stuff like this must drive you crazy! Thanks for all the great support.

I finally updated to 1.26, and am having this problem too. Is there any way to start FreeLSS from the command prompt?

thanks for the tip, trying it now.

Looks like the issue is from the wiringPi library that freelss uses. noticed this message, perhaps there is a new wiringpi lib available
- expecting BCM2708 or BCM2709. Please report this to projects@drogon.net

+1 on this error

unable to determine hardware etc......

After a bit of googling, I have found a way to get the system up and running again by downgrading the kernel version.

I used:

sudo apt-get update
sudo apt-get dist-upgrade

then downgraded kernel to ver. 4.4.50 by using:

sudo rpi-update 52241088c1da59a359110d39c1875cda56496764

FreeLSS now runs on startup, and this will do me for now until hairu gives out a better method

Dusting off this project after a few months. Was probably calibration problems and could not get any good scans.

Updated to 1.26 via web UI. Then software would not start.

Used instructions at https://github.com/hairu/freelss to update manually. Still wont automatically start.

Tried sudo /usr/local/bin/freelss , got
Unable to determine hardware version. I see : Hardware BCM2835

Looked at downloaded source code, freelss/src/Main.cpp is version 1-11

Done apt-get update & upgrade

The Pi board is the standard board that came with the kit - . Using wired connection to eliminate any wifi issues, and KVM on pi board.

any ideas? can download new SD card image if that is easiest fix

Thanks in advance
