  • Koheron OS is installed on the board.

To connect the board directly to your computer, set up a direct Ethernet connection to the board with a static IP address.

Steps

1. Find the network ID

$ ip addr show | grep -w inet | grep eth
inet 192.168.1.11/24 brd 192.168.1.255 scope global dynamic eth0

The network ID is the broadcast address brd with the parts equal to 255 stripped. Here, the network ID is 192.168.1.
