    Hi Alper,

    I don't use macOS, but here is the instruction to SSH connect from Ubuntu 22.04:

    Connect the SK-AM62A Ethernet port to the same network with the Linux PC. Boot SK-AM62A with the SDK8.6, run the following command to assign SK-AM62A an IP address (my Linux PC IP address is 192.168.88.110):

    root@am62axx-evm:~# ifconfig eth0 192.168.88.162

    Then on Ubuntu 22.04 PC:

    dev@ula:~$ ssh 192.168.88.162
Unable to negotiate with 192.168.88.162 port 22: no matching host key type found. Their offer: ssh-rsa
dev@ula:~$ ssh -oHostKeyAlgorithms=+ssh-rsa root@192.168.88.162

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is

Please contact your system administrator.
Add correct host key in /home/lb/.ssh/known_hosts to get rid of this message.
