Hi!
I have a red pitaya that I am supposed to use for my masters project. I have had no success in doing the most trivial of things, like following tutorials, partly because my universities security policies are unbending in that I cannot under any circumstances allow my RP to get online. So for instance right now I am stuck just trying to get the git repository with the examples over to my RP.
I have a RedHat machine, with an extra ethernet card to connect to RP.
It seems the only way I can transfer something to the RP is with sftp (so I have to make a tarball if transferring more than one file). I cannot use scp from SSH because the network doesnt allow me that either apparently. ( I get the message: ssh_exchange_identification: read: Connection reset by peer. So I am just assuming its something to do with the network)
I am not sudo on the PC (also university regulations) and I can therefore not paste stuff directly to the SD card. Ive tried using a larger SD card and partitioning it so as to be able to write directly but I have not succeeded in that.
I wonder if anyone has any tips? Someone who has developed offline? I imagine that using STFP would be an incredible hassle if I have to make changes in a lot of different files.
Is it even possible to have a smooth workflow with RP development when it is not allowed internet access?

Re: Developing on RP without internet access
You can connect a USB cable between the RP (the USB socket next to the power one) and your computer. This sets up a virtual COM port that you can use SSH with. Of course, you may run into a problem if any hardware drivers need to be installed given your policy restrictions. Another possibility - again depending on how locked down you are - is to do a direct PC-to-RP Ethernet connection.

Thanks for your reply John! Its like the second time I have ever gotten a reply here! Yay!
I finally figured out how to circumvent the problem and can use scp now.
Now to figure out how to program the FPGA...

Hi mnordgard,
you might want to check out my project PyRPL at http://pyrpl.readthedocs.io. You only need to install PyRPL on your client computer, all software installation on the RedPitaya is handled automatically by the client..

Hi lene85!
Im sorry for the late reply, I checked out your project and it looks very smooth but to be honest I am just overwhelmed with the things I have been trying to do lately and I dont know if I can afford the time to attempt to learn yet another approach.
But thanks a lot! It is cool that there is people out there actually trying to make the RP easier to use, and helping out in the forum.
