acathlaI'm trying to use LiteX on a Papilio Pro board (spartan 6), it works but the sdram initialization fails. What's the best way to debug that?12:09

geertuIs there an easy way to reinstall litex after an OS upgrade? I upgraded from Ubuntu 20.04 to 22.04 LTS, and now lxterm can no longer find the litex Python packages19:50
somlogeertu: maybe `python3 setup.py develop --user` in each of the distinct litex[-*] and pythondata-* repos will put the right symlinks back into your .local/<whatever> directory?19:56
somlothat is, if you're reluctant to just let `litex_setup.py` do its thing (which I haven't in a loooong time) :)19:57
geertusomlo: I did try messing with litex_setup.py, but I got lots of scary warnings and errors.  Probably my copy is too old to work well with the new Python in 22.0419:58
geertuFWIW, my .local has almost no symlinks, and the few that are present are not related.20:00
geertuI have litex stuff under /usr/local/lib/python3.6/ and /usr/local/lib/python3.8/20:03
geertuUsing "python3.6 /usr/local/bin/lxterm" instead of plain "lxterm20:03
geertu" does something, but fails later when trying to talk to the OrangeCrab. Doh20:03
geertu"sudo python3 setup.py develop" in the litex dir worked20:08
geertuHowever, download fails after a few seconds. Seems like the USB device disappears at random times.20:09
geertuReplugging the board fixed that. Back into business, booting 6.2-rc3...20:12
geertusomlo: thx!20:13
cr1901Huh, I think litex_setup.py has gotten much better over the years. I run it once per week20:16
somlogeertu: I have a bunch of *.egg-link files in $HOME/.local/lib/python3.XX/site-packages, and I'm sure they got there via `setup.py develop --user`, a long time ago21:32
somlothey match the "pythonic" folder structure of my various litex* git repositories21:33
somlobut this would all break if I upgraded my python version (.local/lib/python3.XX -> python3.YY), at which point I'd probably have to re-learn how to set things up :)21:34
somlolitex_setup.py used to 1. do a `git clone [--recursive]` on a list of repos, then 2. do a `setup.py ...` driven by a bunch of options on the command line21:35
somloand probably still does -- haven't needed to touch it in a while :)21:35
