| CarlFK | mithro: I get that - but so far it hasn't helped me understand what is going on when things are broken. | 03:28 |
| CarlFK | mithro: I think it only helps when things don't error, and in that case, not sure it helps. | 03:28 |

| CarlFK | mithro: I've keep paying attention to 'that' (the tails of the outputs) and figure something out - I suspect just styling it different, or even putting it in it's own ``` block will be ok | 03:37 |
| mithro | CarlFK: maybe | 03:37 |
| CarlFK | mithro: back to my arty problem - just booted firmware and linux on qemu. now I am at export CPU=or1k CPU_VARIANT=linux PLATFORM=arty TARGET=net FIRMWARE=firmware | 03:38 |
| CarlFK | source ./scripts/enter-env.sh | 03:39 |
| CarlFK | Already sourced this file. | 03:39 |
| CarlFK | is that ok? | 03:39 |
| mithro | CarlFK: that is fine? | 03:39 |
| CarlFK | mithro: im still confused about the 2 sets of export ... enter-env.sh | 03:40 |
| mithro | CarlFK: ? | 03:41 |
| mithro | CarlFK: You mean "Re-enter LiteX Environment" and "Test loading the gateware and HDMI2USB bare metal firmware via serial" ? | 03:42 |
| CarlFK | ye | 03:42 |
| CarlFK | mithro: yes | 03:42 |
| mithro | CarlFK: The first one is "how you re-enter the litex environment" -- it is a general step, -- the second one has the first step of "re-entering the litex environment" | 03:43 |
| mithro | CarlFK: or more I guess set the "export CPU=or1k CPU_VARIANT=linux PLATFORM=arty TARGET=net FIRMWARE=firmware" values correctly... | 03:44 |
| CarlFK | mithro: I've been thinking of reworking this somehow: https://github.com/timvideos/litex-buildenv/wiki/HowTo-LCA2018-FPGA-Miniconf#resuming-development | 03:48 |
| tpb | Title: HowTo LCA2018 FPGA Miniconf · timvideos/litex-buildenv Wiki · GitHub (at github.com) | 03:48 |
| CarlFK | mithro: not change the lines...but the way the doc talks about it | 03:48 |
| mithro | CarlFK: "Re-enter LiteX Environment" and "Resuming Development" are the same I guess... | 03:49 |
| CarlFK | mithro: like it is a dupe of the lines right above it, so remove those lines ad say "for any of these script to work, both now and if you ever start a new shell, set these vars and run this script:" | 03:49 |
| CarlFK | right | 03:49 |
| CarlFK | Re-enter can be "rember, you need to [link to Resuming... | 03:50 |
| CarlFK | mithro: er, wait. this is what I was confused about. let me ask again: | 03:51 |
| CarlFK | mithro: even in the same shell, if I do this: export CPU=or1k CPU_VARIANT=linux PLATFORM=arty TARGET=net FIRMWARE=firmware | 03:52 |
| CarlFK | do I need to source ./scripts/enter-env.sh ? | 03:52 |
| mithro | CarlFK: If you haven't entered the environment | 03:53 |
| CarlFK | mithro: so if I am still "in" I can do the export.. ; make gateware-load ? (no enter-env.sh?) | 03:55 |
| mithro | CarlFK: Well, you will need to rebuild the gateware | 03:55 |
| CarlFK | does this rebuild the gateware? source ./scripts/enter-env.sh | 03:56 |
| CarlFK | mithro: looks like that step is missing. which may explain why the arty isn't booting .. something. I've been trying to re-verify and see what went wrong, and that's hard when I am also trying to verify the docs | 03:58 |
| mithro | CarlFK: If you change CPU/CPU_VARIANT/PLATFORM you need to rebuild gateware | 03:59 |
| mithro | If you just change the FIRMWARE value, you shouldn't need to rebuild it | 03:59 |
| CarlFK | mithro: CPU/CPU_VARIANT/PLATFORM is the same for qemu and arty? | 04:01 |
| mithro | CarlFK: yes? | 04:02 |
| mithro | The only thing which changes is FIRMWARE | 04:03 |
| CarlFK | mithro: just checking. I was expecing qemu to be it's own platform | 04:03 |
| mithro | From FIRMWARE=linux for Linux and FIRMWARE=firmware for HDMI2USB Bare Metal firmware | 04:03 |
| mithro | CarlFK: qemu emulates existing platforms | 04:03 |
| mithro | CarlFK: It pretends to be an Arty, or an Opsis, or a Atlys depending on what you set the PLATFORM value to be.... | 04:04 |
| CarlFK | mithro: oh neat | 04:04 |
| CarlFK | mithro: ok, im blocked here. im sure I followed howto, but Arty isn't booting. http://paste.ubuntu.com/p/fvGb5J9V6Q/ | 04:05 |

| CarlFK | mithro: yay!! it's loading.. loaded firmware | 04:06 |

| nrossi | mithro: So I managed to get the symbiflow-arch-defs build going in OE (https://github.com/nathanrossi/meta-hdl/commit/e2a85fa2407ec88bf56636857cb17332802b810f), but it currently fails to route the ice40 hx8k murax test no idea if that is expected or not? | 14:56 |

| mithro | nrossi: I think we ran travis-ci out of memory | 18:35 |
| nrossi | mithro: makes sense. If i set CI in my build everything runs to completion, so it might just be broken | 18:36 |
| mithro | nrossi: Okay, I'll poke some people | 18:37 |
| mithro | nrossi: So it seems like many of the pieces needed to make a "litex-buildenv" equivalent using yocto / bitbake / openembedded are falling into place... | 18:37 |
| *** lufijP has joined #timvideos | 18:39 | |
| mithro | nrossi: I would love to formulate a more concrete plan on how to such a "litex-buildenv" thing a reality but not sure how to do it. Still got mostly random notes in https://docs.google.com/document/d/1hBvcE83vDRn5EVzcv4Qv_dcGlDuXp5pNI-_yzrEOwxs/edit ? | 18:40 |
| tpb | Title: LiteX BuildEnv based on Yocto - Google Docs (at docs.google.com) | 18:40 |
| nrossi | mithro: so i started playing with getting litex building a target within oe https://github.com/nathanrossi/meta-hdl/blob/wip/recipes-examples/litex-demo/litex-demo.bb | 18:42 |
| tpb | Title: meta-hdl/litex-demo.bb at wip · nathanrossi/meta-hdl · GitHub (at github.com) | 18:42 |
| mithro | nrossi: Yeah, I saw.... | 18:42 |
| nrossi | mithro: but i hit some issue that i suspect are related to the splitting of code between litex-buildenv and straight litex | 18:42 |
| nrossi | mithro: although i was trying to build lm32 on a tinyfpga-bx platform, which i believe is not exactly fully completed? | 18:43 |
| mithro | nrossi: Happy to take a look if you have something more I could try? | 18:43 |
| mithro | nrossi: Should be working in some configurations -> https://travis-ci.org/timvideos/litex-buildenv/builds/436206846 | 18:44 |
| mithro | nrossi: C=lm32.lite P=tinyfpga_bx F=stub T=base is green | 18:44 |
| *** lufijP has quit IRC | 18:45 | |
| mithro | nrossi: Looks like you might need to supply the cpu variant to be the "lite" configuration of the lm32 | 18:45 |
| nrossi | mithro: ah ok, is the "base" target some default in litex? | 18:45 |
| mithro | nrossi: Dunno how it maps to "litex.boards.targets.simple" .... | 18:46 |
| mithro | nrossi: It's defined here -> https://github.com/timvideos/litex-buildenv/blob/master/targets/tinyfpga_bx/base.py | 18:46 |
| tpb | Title: litex-buildenv/base.py at master · timvideos/litex-buildenv · GitHub (at github.com) | 18:47 |
| nrossi | mithro: i see, yer thats what i was confused about, there appears to be duplication/splitting of targets/platforms between litex and litex-buildenv. I was not sure what the purposes of that was, I suspect its just so that you don't need to put it into the litex repo itself? | 18:49 |
| nrossi | mithro: i will have a better look at getting that going tomorrow. Also I have a number of questions around various pieces (litex/symbiflow/etc) and how to better integrate them/etc. I will write them down for you and query you on them tomorrow. It is getting quite 'early' (~5am) so im going to head off for now :) | 18:56 |
| mithro | nrossi: SGTM! Feel free to dump them in the google doc here -> | 18:57 |

| CarlFK | mithro: if I set up a nic with: sudo ifconfig enx00e04c680b24 inet 192.168.100.100 up - and then try to boot firmware on qemu, will the hardware 192.168.100.100 interfere with the tap setup? | 23:33 |
| CarlFK | mithro: qemu isnt working and that's my guess | 23:33 |
| mithro | CarlFK: I think so, but unsure | 23:33 |
| CarlFK | mithro: thanks - thats more than enough for me to look into that more | 23:34 |
| mithro | See the advanced network setup which allows both | 23:34 |
| mithro | I've forgotten a lot of my Linux networking voodo | 23:35 |
| CarlFK | mithro: simply del-ing the eth interface fixed my problem, so yeah, that was it | 23:55 |
