scp back and forth to Xilinx embedded platform

When scp .xclbin files from the host machine to the embedded platform or scp results back to the host machine, we don’t want to type in id/password every time.

When first boot the embedded platform(ZCU102 for example), at ZCU102, vi ~/.profile,

ifconfig eth0 10.10.7.1 netmask 255.0.0.0

When ZCU102 boots, it will automatically set its ip as 10.10.7.1(an example addr).

From workstation to ZCU102(for example)

Set a neighboring ip for the workstation like 10.10.7.2. Then, at workstation, generate ~/.ssh/id_rsa_zcu102 and ~/.ssh/id_rsa_zcu102.pub In ~/.ssh/config,

Host zcu102
    HostName 10.10.7.1
    User root
    IdentityFile ~/.ssh/id_rsa_zcu102
    StrictHostKeyChecking no

Then, in ZCU102, mkdir .ssh and vi ~/.ssh/authorized_keys, add id_rsa_zcu102.pub. Finally, at workstation, try ssh zcu102 to login without typing id/password.

From ZCU102 to workstation

At ZCU102, cd ~/.ssh,

dropbearkey -f id_rsa -t rsa

to generate id_rsa. Public key is shown in terminal. Copy public key to workstation’s ~/.ssh/authorized_keys. Try ssh -i ~/.ssh/id_rsa USER_NAME@10.10.7.2.
