| mithro | shorne: Is or1k in upstream gdb? | 01:56 |
|---|---|---|
| shorne | mithro: yes, for bare metal debugs | 02:36 |
| shorne | i.e. not linux apps (yet) | 02:36 |
| shorne | mithro: the sim build is coming along, it seems litex added verilator --threads support (a new feature in litex). The debian version of verilator does not support threads yet, but I think your conda version does. | 02:37 |
| mithro | shorne: Maybe | 02:37 |
| shorne | Do you have any good way to not wait so long for getting results from a travis build? | 02:38 |
| mithro | shorne: Cancel the ones you don't care about? | 02:38 |
| shorne | I see | 02:39 |
| mithro | shorne: I generally try and run things locally first | 02:39 |
| shorne | I have created a docker image that kind or reproduces the environment... | 02:39 |
| shorne | yeah, it works locally, just the travis image is so different then my fedora workstation, hence the docker image | 02:40 |
| mithro | shorne: Got a link to th elogs? | 02:42 |
| shorne | https://travis-ci.org/timvideos/litex-buildenv/jobs/437930041 | 02:51 |
| shorne | mithro: the line is here: https://travis-ci.org/timvideos/litex-buildenv/jobs/437930041#L3770 | 02:52 |
| mithro | shorne: You can enable travis on your own repo | 02:52 |
| shorne | yeah, I was thinking to do that too, also my repos have "debug" access | 02:52 |
| mithro | ethernet.c:6:10: fatal error: event2/listener.h: No such file or directory | 02:55 |
| shorne | I think that was fixed... | 02:56 |

| tpb | Title: Merge aece561e401dfc981d27e75994d3fd07f73cf69c into 0eab7302da7584eee… · timvideos/litex-buildenv@57151f7 · GitHub (at github.com) | 02:58 |
| shorne | mithro: you gave a commit id? event2 missing was due to missing libevent2-dev package | 02:58 |
| mithro | shorne: Ahh | 02:58 |
| shorne | I added it to .travis.yml... which brings the question, should I add that to download-env-root.sh too? | 02:58 |

| mithro | shorne: So, typing "make gateware" seems to start verilator and start the HDMI2USB firmware? | 03:01 |

| tpb | Title: Snippet | IRCCloud (at www.irccloud.com) | 03:02 |
| shorne | mithro: yes, its part of the build _run_sim(), is that not normal? It seems the same on arty if I recall | 03:04 |
| shorne | mithro: did your <enter> work? after typing 'help'? | 03:04 |
| mithro | shorne: Well, "make gateware" not ever ending means the travis build will fail | 03:04 |
| mithro | shorne: no | 03:05 |
| shorne | ok, ill change the build to no longer do that then | 03:06 |
| shorne | need to debug the <enter> think too. I debugged the uart and can see the letters being typed | 03:07 |
| shorne | mithro: but I didnt see <enter> characters coming through, it might be a termios thing | 03:08 |
| mithro | shorne: The problem is likely \r\n verse \n | 03:08 |
| shorne | the code dues try to inter an | 03:10 |
| shorne | mithro: verilator stub does try to insert a '\r' it might be wrong | 03:11 |

| mithro | shorne: Can I push to your branch? | 03:12 |
| shorne | shorne: what do you mean by push? | 03:13 |
| mithro | shorne: I have two minor fixes to your change | 03:13 |
| shorne | mithro: oh, I didnt see your changes | 03:15 |
| shorne | I keep force pushing updates | 03:15 |
| shorne | like a few minutes ago | 03:15 |
| mithro | shorne: Yes, and I want to force push to your branch too | 03:15 |
| shorne | sure, do you want me to give you access? | 03:16 |
| shorne | mithro: do you need access? | 03:16 |
| mithro | shorne: I think I can already because of your pull request | 03:16 |
| mithro | shorne: 383c8be72f1d9287a98fbd3a068887fdcad2f96f | 03:17 |
| shorne | ok, let me see | 03:17 |
| mithro | shorne: Didn't fix the `make gateware`issue though | 03:18 |
| shorne | mithro: I see , b/scripts/enter-env.sh | 03:22 |
| shorne | mithro: looks good, I got it | 03:22 |
| shorne | did you see my comment about the firmware.fbi in `targets/sim/base.py` | 03:22 |
| shorne | mithro: I dont think we should be creating the file name there, but we are... | 03:23 |
| mithro | hrm... | 03:25 |
| mithro | https://www.irccloud.com/pastebin/T36ngSdd/ | 03:25 |
| tpb | Title: Snippet | IRCCloud (at www.irccloud.com) | 03:25 |
| shorne | mithro: for one we do it in make.py, for 2 the current way doesn't support '.linux' | 03:26 |
| shorne | mithro: I saw this error too | 03:28 |
| shorne | I had to edit the installed verilator .h file | 03:28 |
| *** rohitksingh has quit IRC | 03:29 | |
| shorne | something wrong with how they define the #ifdefs for defining fatal_difference() | 03:30 |
| mithro | Yeah, looks like "#if defined(VL_THREADED) && defined(VL_DEBUG)" | 03:32 |
| shorne | mithro: on my file /usr/share/verilator/include/verilated.h | 03:32 |
| shorne | yead, I changed to | 03:32 |
| shorne | #if defined(VL_THREADED) //&& defined(VL_DEBUG) | 03:33 |
| shorne | we probably need to send patch upstream | 03:33 |
| shorne | but I didnt have time yet ;) | 03:33 |
| shorne | We could also patch the .cpp file I guess | 03:34 |
| mithro | shorne: Looks like it's already upstream | 03:37 |
| mithro | shorne: Should be updated in conda soon | 03:39 |
| mithro | oh look, riscv is also in gdb 8.2 | 03:44 |
| shorne | mithro: cool, sorry baby woke up will be away | 04:02 |
