zyp | did you do a pci rescan? | 00:45 |
---|---|---|
nwest | didn't know that as a thing to do, but I just tried `echo 1 > /sys/bus/pci/rescan` and no change | 01:04 |

nwest | aha, I'll need to work out the exact sequence, but it's a bit of a crapshoot now. the rescan is an important bit, but there's some order of not having module loaded, load gateware, load module, rescan that does seem to work but is sensitive | 01:13 |
nwest | thanks | 01:13 |
nwest | the confounding info here is I'm operating over a TB3 extension board, so cable gets plugged/unplugged between some uses. It will consistently work if I do | 01:16 |
nwest | 1) rmmod | 01:16 |
nwest | 2) load gateware | 01:16 |
nwest | 3) init / load module | 01:16 |
nwest | 4) rescan | 01:16 |

j4cbo | so, i'm using litex for a very small system (iCE40, SERV softcore) where I really don't need anything the litex BIOS provides but will instead just put all my code (<4kB) in block RAM | 01:36 |
j4cbo | is there a way to get the litex Builder to compile it for me as part of building the SoC, the way it normally builds the BIOS, or do i need to just compile my code myself and use compile_software=False and soc.initialize_rom()? | 01:36 |

nwest | Also seems to reliably work if I | 03:26 |
nwest | 1) rmmod litepcie before unplugging | 03:26 |
nwest | 2) load gateware | 03:26 |
nwest | 3) init.sh (insmod) | 03:26 |
nwest | no rescan required. Any ideas if there's some hotplug detach events that could be caught to handle this unplug nicer? | 03:26 |
