Setting Up a remote FPGA Farm using DSEII with SSH

[Pedro_Borges]

Hi, we are trying to set up a remote FPGA Farm using DSEII and SSH to make the connection between a Windows PC and an Arch Linux Server (running on an Intel® Nuc). At the beginning, we were following this video: https://www.youtube.com/watch?v=WdO5VOQkl7s&pp=ygUNZnBnYSBmYXJtIGRzZQ%3D%3D but we didn't find it useful enough.

We then found this response: https://community.intel.com/t5/Intel-Quartus-Prime-Software/remote-farm-machine-setup/m-p/1344201 and followed the steps.

Both computers have Quartus Prime Software Installed and we have already managed to get an SSH connection via PuTTY using keyfiles without the need of a password. But when we try to make an exploration using DSEII it outputs the following error message:

We are not sure if we are setting up the parameters correctly. We have tried from the gui and from the console and both of them display the same error message specified above. We would like to know if we have misunderstood some of the settings or if we have wrote them using a bad syntax.

Here are the settings that we used for both tries:

private_key: C:\Private_key\id.rsa.ppk

Local to Remote Path Mapping: D:\Pedro\FIUADY\Servicio\Quartus;/home/lab/Codes/FPGA

Initial Working Directory: /home/lab/Codes/FPGA

Hi,

Based on the error message you got, the machine is not able to get the IP address of the local host. In the DSE II Server Settings, go to the Host field and enter the IPv4 address of the local machine.

Hi, thanks for your response!

I entered my IPv4 Address in additional arguments as "--host 127.0.0.1" and it worked!

But now I'm having another issue, I would be happy if you could help me with this one too:

What could cause this?

Hi,

I'm not a DSE II expert. May I know if this the peewee.py file is yours/part of your design or something that comes with the DSE II and has to be used by it?

Regards,

Nurina

[Pedro_Borges]

Hi again,

peewee.py file is totally from DSEII and I have no idea why we are getting this error. I will check out the links you provided and hopefully find out.

Thanks and regards.
