Hi Guillermo, It seems to be snapshot specific. The intro tutorial doesn't use the snap shot and that is why it works. This should work. I do recall seeing something like this before - Wesley New might have encountered this.
Please can you send me the exact git hash of the mlib_devel and casperfpga you are using. You could also try use the casperfpga in: https://github.com/casper-astro/tutorials_devel/tree/workshop2019 as a sanity check? The caper-astro/casperfpga repo has recenty been updated and merged into master: https://github.com/casper-astro/casperfpga/commits/master. Therefore, the "tutorials2019" branch has been deleted for casperfpga. I would first try the https://github.com/casper-astro/tutorials_devel/tree/workshop2019 casperfpga version used in the tutorials_devel repo and then the https://github.com/casper-astro/casperfpga/commits/master. If the problem still occurs for both then we can explore the toolflow version. I assume you are still running casperfpga using Python 2.7 and the toolflow in Python 3? I am now using python virtual environments.
