Hi,

I am new to the ARTIQ system. I plugged my Hardware to power and connected SFP0 [Ethernet to a LINKSYS router].

I adjusted the router addresses as

Reason being as mentioned in the documentation IP for the device would be: 192.168.1.75 [But I am unable to ping the device back].

Now I tried to run simple LED program mentioned in the documentation at Getting started guide

I tried running this code with beta version as well as stable version, but the error code is the same [respectively],

I suspect there is an issue with device_db.py as well as Gateware/Software version. I tried to download a version supported by the Gateware, but it is hard to find. Please suggest me some solution.

I am adding device_db.py which I'm using and some supporting photos. Please let me know if I connected the SFP connector properly.

Thanks in advance.

Sometimes, red LED [ERR] glows over Fastino.
