Hi Jeff, The toolflow is normally used with a Python virtual environment setup with Python 3. The casperfpga tool (provides comms to the board) uses just python 2.7. This is the way we use the toolflow and casperpfga at SARAO (South African Radio Astronomy Observatory). We support the SKARAB and Red Pitaya. There are Python 3 versions for casperfpga, but we haven't really tested these on the SKARAB or Red Pitaya.
I have been using Ubuntu 16.04LTS, but I know this also works on Ubuntu 18.04LTS. I still need to test my SKARAB on Ubuntu 18.04LTS, which I will do in the next couple of weeks. Here is some documentation to install the toolflow on your system and explains the virtual environment: https://casper-toolflow.readthedocs.io/en/latest/src/Installing-the-Toolflow.html Here is some documentation to install casperfpga on your system: https://casper-toolflow.readthedocs.io/projects/casperfpga/en/latest/How-to-install-casperfpga.html Here are the ska-sa (SARAO) repos which has the latest for SKARAB and Red Pitaya: 1) https://github.com/ska-sa/casperfpga/tree/devel (casperfpga) 2) https://github.com/ska-sa/mlib_devel/tree/devel (toolflow) Here are the casper-astro repos, which the majority of the CASPER community uses: 1) https://github.com/casper-astro/mlib_devel - this actually does work with the SKARAB and Red Pitaya too. You still need a Python 3 virtual environment if your default python package is 2.7. 2) https://github.com/casper-astro/casperfpga - this should work with SKARAB and Red Pitaya too (Python 2.7) 3) https://github.com/casper-astro/casperfpga/tree/py3-merge - this works with SNAP, but I haven't tested it on SKARAB or the Red Pitaya. It may work on the Red Pitaya, but I believe there are still issues with SKARAB (Python 3) I hope this helps!
