I posted this on the Altera board, but the moderator hasn’t approved it yet. We just received some Arria 10 SoC dev kits (not the gx kits). I’ve been successful with creating a lab network with a DHCP server and the boards intermittently boot up and receive IP Addresses. Sometimes I have to warm boot multiple times to get the LCD to display anything or get the status lights to cycle, indicating it’s booted up. Sometimes I have to cold boot it to get it running. When it does boot and receive an IP address, the web interface works, but I can’t ssh to it. It acts like the sshd isn’t accepting my host or doesn’t allow root to login. The first time I try, I get a certificate:
$ ssh root@192.168.0.28
The authenticity of host ‘192.168.0.28 (192.168.0.28)’ can’t be established.
ECDSA key fingerprint is SHA256:6Roa+AUDD3RyzVleUJS04lWWt7tdVvD1LrZBkHTwADE.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘192.168.0.28’ (ECDSA) to the list of known hosts.
Connection to 192.168.0.28 closed by remote host.
Connection to 192.168.0.28 closed.
Then each time after, I get:
$ ssh root@192.168.0.28
Connection to 192.168.0.28 closed by remote host.
Connection to 192.168.0.28 closed.
Is there any way to connect to the tty and login via USB or RS232?
