cr1901_modern_florent_: Could you elaborate on what you mean by this commit? I want to update to a future version which provides Lite and Min variants:

cr1901_modernmithro: If you read the above, I used my own local copy w/ changes to test "vexriscv.lite". But at present there is no such thing in litex itself07:00

_florent_cr1901_modern: it seems there was a regression with vexriscv version later than this one, it was not working correctly on hardare. I haven't found time to see if it was related to vexriscv itself or integration in litex07:47
_florent_cr1901_modern: basically, with new version, it was not possible to load a firmware with serialboot and then execute it07:48
cr1901_modernWell I guess I could try to duplicate your setup and run a bisect this weekend07:49
cr1901_modern_florent_: Do you remember the commit and your setup from when it started crashing (which board? was it custom firmware? litex-buildenv? Just the LitexBIOS plus serialboot?)?07:50
cr1901_modernI can't bisect if I can't duplicate your problem :P07:51
_florent_cr1901_modern: that's related to the vexriscv update07:58
_florent_cr1901_modern: to reproduce, use latest litex, prepare a design where you load a firmware with serialboot and verifiy it works08:00
_florent_cr1901_modern: then just update vexriscv to latest version and see if it's working or not08:00
cr1901_modern_florent_: Okay will do08:03

shorneCarlFK: that hardware doesnt exist in qemu20:06
shornethat is expected20:07
CarlFKshorne: got it - thanks20:07
shorneWe probably should add something that provides the details, there might actually be something in qemu20:08
CarlFKI really just want to tell me what I have done - I look at my screen, I see a prompt, I'm not sure how I got there20:19
shorne_florent_: I updated the "random notes doc here"20:59

shorneI am not sure if there is a better one20:59

shornemithro: I updated that old linux bootstrap docs from H2U to Litex-Buildenv, I hope that is OK, also I added a few notes on network setup21:01
shorneCarlFK: what instructions are you following?21:02
shorneCarlFK: when you say "tell what I have done" you mean just to know that you are on qemu or a real board?  If its a real board you will usually see "[FLTERM]" because we use that to connect to the boards serial device at '/dev/tty...'21:04
shorneshenki: FYI, I was able to see linux networking working on my arty board with the latest litex firmware.  i.e. SSH works21:05
shorne(using your liteeth linux driver) did you have problems with that before?21:06
shenkishorne: i recall initially having issues. I think the last time I touched it it was working22:21
shenkishorne: the driver is very inefficant, due to very simple hardware22:22
shenkishorne: you also might find it does not free memory, so your system will eventually oom22:22
