Kasli can't connect into the ethernet

Swerwuone

I am trying to connect a Kasli v2.0.1 board into our lab's network. Both the board's SFP0 port and the lab computer are connected to an ethernet switch. The led of SFP0 is on and the error light is off. But when I tried to ping 192.168.1.75 on a windows system it failed with timeout. I tried to see all the devices in the network by the command line arp -a and Ipconfig/all but plugging in and out the cable to the Kasli board doesn't change the number of devices shown. It seems the board was never connected into the local network. What should I do?

architeuthis

Have you checked the UART log? All boards have a serial interface at 115200bps 8-N-1 (use something like PuTTY to connect if you're on Windows).

Some ideas

Have you set the netmask together with the IP for the ARTIQ, e.g., 192.168.1.75/22?
Do you have multiple ethernet ports on your computer?
Are you sure the IP range is free and not user by some other services?
Did you run a port scanner (for Windows: angry ip) for the default ports?

I would also advise to check through common problems: https://git.m-labs.hk/sinara-hw/assembly/src/branch/master/src/sw_sup/networking.md#common-problems .

UART logs would also be nice, we have a small guide how to set up drivers on windows and collect them: https://git.m-labs.hk/sinara-hw/assembly/src/branch/master/src/sw_sup/uart_logs.md

Hi, architeuthis, bodokaiser and esavkin! Thank you so much for your reply! The problem seems to be solved.
Following the guide on https://git.m-labs.hk/sinara-hw/assembly/src/branch/master/src/sw_sup/uart_logs.md, I read the following UART logs:

My supervisor told me to connect a cable directly between the Kasli board and the computer, and manually set the computer's IP address to 192.168.1.1. After this, ping 192.168.1.75 command succeeded. I changed Kasli's IP address into 192.168.110.75 using $ artiq_coremgmt -D 192.168.1.75 config write -s ip 192.168.110.75 and $ artiq_coremgmt -D 192.168.1.75 reboot, for the original IP address of the lab computer starts with 192.168.110. Finally I reconnected the computer and the board into the local network and edited device_db.py. Now the Kasli board becomes accessible under the new address and example experiments like led.py are runnable.
