| 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: https://github.com/enjoy-digital/litex/commit/948527b0fe8e4bfee8b5010dd8dc119655db2758 | 06:54 |

| cr1901_modern | mithro: 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 itself | 07:00 |
| cr1901_modern | upstream* | 07:00 |

| _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 litex | 07:47 |
| _florent_ | cr1901_modern: basically, with new version, it was not possible to load a firmware with serialboot and then execute it | 07:48 |
| cr1901_modern | Well I guess I could try to duplicate your setup and run a bisect this weekend | 07:49 |
| 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_modern | I can't bisect if I can't duplicate your problem :P | 07:51 |
| _florent_ | cr1901_modern: that's related to the vexriscv update | 07:58 |
| _florent_ | cr1901_modern: to reproduce, use latest litex, prepare a design where you load a firmware with serialboot and verifiy it works | 08:00 |
| _florent_ | cr1901_modern: then just update vexriscv to latest version and see if it's working or not | 08:00 |
| cr1901_modern | _florent_: Okay will do | 08:03 |

| shorne | hmm, network is kind of working too | 13:05 |
| shorne | I can ssh | 13:06 |
| CarlFK | ohh nice | 13:13 |
| CarlFK | does it do dhcp? | 13:13 |
| shorne | CarlFK: I just did 'ifconfig eth0 192.168.100.50 up' | 13:15 |
| shorne | and I ssh'd back to 192.168.100.100 on my local machine | 13:15 |
| shorne | and it worked | 13:15 |
| shorne | The prompt to access the host identity didn't work , so I did 'ssh [email protected] -y' | 13:16 |
| shorne | -y to disable key checking | 13:16 |

| shorne | there is an ssh server running by default too, it seems to work, I cant log in though even after creating a user | 13:21 |
| shorne | anyway, need to go to sleep | 13:22 |
| CarlFK | see ya | 13:24 |
| _florent_ | shorne: cool thanks. Are there some instructions i can follow to replicate your results? | 13:51 |

| shorne | CarlFK: that hardware doesnt exist in qemu | 20:06 |
| shorne | that is expected | 20:07 |
| CarlFK | shorne: got it - thanks | 20:07 |
| shorne | We probably should add something that provides the details, there might actually be something in qemu | 20:08 |
| CarlFK | I 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 there | 20:19 |
| shorne | _florent_: I updated the "random notes doc here" | 20:59 |

| shorne | mithro: 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 setup | 21:01 |
| shorne | CarlFK: what instructions are you following? | 21:02 |
| shorne | CarlFK: 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 |
| shorne | shenki: FYI, I was able to see linux networking working on my arty board with the latest litex firmware. i.e. SSH works | 21:05 |
| shorne | (using your liteeth linux driver) did you have problems with that before? | 21:06 |
| shenki | shorne: i recall initially having issues. I think the last time I touched it it was working | 22:21 |
| shenki | shorne: the driver is very inefficant, due to very simple hardware | 22:22 |
| shenki | shorne: you also might find it does not free memory, so your system will eventually oom | 22:22 |
