Once again… many thx.
Ok, I set debuglevel to 9 and checked the log.
After finding some corrupt files (and removing them) firefly now seems to run smooth.
Next issue is that my Pinnacle SB cannot find the server. Read some threats ans it seems that I need a Bonjour/Avahi service to make firefly visible.
Hope you can help me once again: How to activate (install?) those services on my NSLU2 ❓
