I'd suggest start by trying the casperfpga which is included as a git submodule in the tutorials repo -- https://github.com/casper-astro/casperfpga/tree/a88f9af0b16e6a12fe51884d29c162e76e7c21a6
I'm guessing this is substantially older than the one you are using, and may be python2.7 only. As some wild guesses, you could also try manually setting which memory map to use, by adding, after this line <https://github.com/casper-astro/tutorials_devel/blob/8cdfd2f0fe6ed65d4d9906a22abc48761a2c04cc/roach2/tut_tge/roach2_tut_tge.py#L118> gbe_rx.memmap_compliant=False gbe_rx.memmap = casperfpga.tengbe.read_memory_map_definition(casperfpga.tengbe.TENGBE_MMAP_LEGACY_TXT) If that fails to work, as another stab in the dark, you could try the opposite: gbe_rx.memmap_compliant=True gbe_rx.memmap = casperfpga.tengbe.read_memory_map_definition(casperfpga.tengbe.TENGBE_UNIFIED_MMAP_TXT) Not sure any of this is likely to result in success, but it's the best guess I have!
