zypdid you do a pci rescan?00:45
nwestdidn't know that as a thing to do, but I just tried `echo 1 > /sys/bus/pci/rescan` and no change01:04

nwestaha, 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 sensitive01:13
nwestthanks01:13
nwestthe 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 do01:16
nwest1) rmmod01:16
nwest2) load gateware01:16
nwest3) init / load module01:16
nwest4) rescan01:16

j4cboso, 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 RAM01:36
j4cbois 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

nwestAlso seems to reliably work if I03:26
nwest1) rmmod litepcie before unplugging03:26
nwest2) load gateware03:26
nwest3) init.sh (insmod)03:26
nwestno rescan required. Any ideas if there's some hotplug detach events that could be caught to handle this unplug nicer?03:26
