Dear June, I am sorry you are encountering this problem. SKARAB has only been baselined and fully tested using Python 2.7 for casperfpga. Yes, some attempts have been made to port it to Python 3.8, but as far as I am aware there have been issues that were never fully sorted out. It looks like you may be encountering those.
I would try to run it using Python 2.7 first. NB: SKARAB baseline testing suggested versions: *Toolflow*: Ubuntu 18.04LTS, Python 3.6 (Virtual environment), Matlab R2018a, Vivado 2019.1.1. *casperfpga*: Ubuntu 18.04LTS, Python 2.7 (Virtual environment) It should be pointed out that work has been done on the toolflow to get it to work with Ubuntu 18.04LTS, Python 3.8, Matlab R2021a and Vivado 2021.1. NB: Please note that we had issues running some of the tutorials and that the base driver IP for Ethernet and most drivers remain at the Vivado 2019.1.1 version for SKARAB, so it is not fully ported at all levels. It should be pointed out that at this point our DSP team are currently using SKARABs for new development with these new versions, so they may end up sorting all these issues out in the long run, but if you want a fully baselined and tested SKARAB version now then I would stick with the recommended baseline versions. Good luck!
