| shorne | mithro: good news | 03:20 |
| mithro | shorne: ? | 03:22 |
| shorne | mithro: on the toolchain working | 03:24 |
| shorne | I didnt check the rest yet, still messing with the sim networking stuff | 03:25 |
| mithro | shorne: ahh, not "I have good news" but "congratulations on the good news" | 03:25 |
| shorne | mithro: yes.. did you see _florent 's comments on the uart \r\n changes. He recons we should change our firmware to change how we detect commands to be inline with the litex BIOS | 03:31 |
| shorne | easy change, but I didnt want to break anything | 03:31 |
| mithro | shorne: I think we moved to \r\n to be more compatible with other terminals? | 03:31 |
| shorne | mithro: as I see here: https://github.com/timvideos/litex-buildenv/blob/master/firmware/ci.c#L235-L294 | 03:31 |
| shorne | it looks like we use \n for telnet sessions and \r for uart connections | 03:31 |
| shorne | we ignore \r, and \n respectively | 03:31 |

| shorne | mithro: so cr/lf on output, but input is just the one | 03:33 |
| shorne | I see the patch | 03:34 |
| shorne | that is what telnet was already doing, but opposite . Maybe we just copy telnet? | 03:35 |
| mithro | https://github.com/timvideos/HDMI2USB-litex-firmware/pull/341/commits | 03:35 |

| shorne | yeah, I see that as CR-LF on outout | 03:36 |
| shorne | (mostly) | 03:37 |
| shorne | well... BIOS doesnt so it quite correct then either | 03:38 |

| shorne | mithro: now with the latest verilator + c++ packages it seems the conda environment needs libevent and json-c | 03:47 |
| shorne | let me try to just install the conda channel ones | 03:47 |
| shorne | i.e. | 03:47 |
| shorne | 86_64-conda_cos6-linux-gnu/bin/ld: cannot find -levent | 03:47 |
| shorne | x86_64-conda_cos6-linux-gnu/bin/ld: cannot find -ljson-c | 03:47 |
| mithro | Hrm, I wonder why that didn't fail on travis? | 03:47 |
| shorne | The verilator travis? or litex-buildenv travis? | 03:47 |
| shorne | verilator itself doesnt need it, these libs is brought into the verilator simualtor by litex | 03:47 |
| mithro | Oh - the libevent / json-c is just needed for the litex? | 03:47 |
| shorne | mithro: yes | 03:47 |
| shorne | Ill see if I can get the regular conda libs to satisfy those dependencies, its still complaining after installing | 03:48 |
| mithro | shorne: export PLATFORM=sim ? | 03:49 |
| shorne | yes | 03:50 |
| shorne | Before it was working find for me, because I used 'fedora's' verilator | 03:50 |
| shorne | which used g++ | 03:50 |
| shorne | but now I am getting this with the new conda verilator | 03:50 |
| shorne | I did 'conda install json-c libevent' | 03:51 |
| shorne | it installed the .so files in 'build/conda/lib' | 03:51 |
| shorne | its still not linking | 03:52 |
| shorne | looking into it... | 03:52 |
| mithro | AssertionError: ROM contents not found! /home/tansell/github/timvideos/HDMI2USB-litex-firmware/build/sim_base_or1k/software/firmware/firmware.fbi | 03:52 |
| shorne | Final build command is | 03:52 |
| shorne | x86_64-conda_cos6-linux-gnu-c++ -lpthread -ljson-c -lm -lstdc++ -ldl -levent veril.o dut_init.o verilated.o verilated_vcd_c.o Vdut__ALL.a modules.o pads.o sim.o libdylib.o parse.o -lpthread -ljson-c -lm -lstdc++ -ldl -levent -pthread -lpthread -latomic -o Vdut -lm -lstdc++ | 03:53 |
| *** rohitksingh_work has joined #timvideos | 03:53 | |
| shorne | oh... I thought I fixed that issue | 03:53 |
| shorne | are you using CPU_VARIANT=linux? | 03:53 |
| mithro | shorne: oh - yes | 03:54 |
| shorne | yeah, I have a patch for that, havent pushed yet | 03:54 |
| shorne | one second let me push | 03:54 |
| mithro | ethernet.c:6:10: fatal error: event2/listener.h: No such file or directory | 03:55 |
| shorne | pushed | 03:56 |
| shorne | yeah, that is part of 'libevent' | 03:56 |
| shorne | meaning '-I''s are getting passed fine | 03:56 |
| shorne | Sorry, I mean, for me, I can see the -I's are being passed during the compile phase | 03:57 |
| shorne | but during link phase its not adding the -L's if that makes sense | 03:57 |
| shorne | I dont have any special LDFLAGS/CFLAGS set | 03:58 |
| mithro | What do you have in /home/tansell/github/timvideos/HDMI2USB-litex-firmware/third_party/litex/litex/build/sim/core/modules/variables.mak ? | 04:00 |
| shorne | https://gist.github.com/2bc9e612094d159bbd8bf330b668d8b8 | 04:01 |
| tpb | Title: variables.mak · GitHub (at gist.github.com) | 04:01 |
| shorne | NOthing special | 04:02 |
| shorne | mithro: do you know where we inject build/conda/... paths into LDFLAGS / CFLAGS? | 04:08 |
| shorne | is that build into the conda binaries with RPATH or something/ | 04:09 |
| shorne | ? | 04:09 |
| shorne | mithro: It looks like it... one minute | 04:14 |
| mithro | ./build/conda/bin/x86_64-conda_cos6-linux-gnu-cc -print-search-dirs ? | 04:17 |
| shorne | yeah... I ran it | 04:22 |
| CarlFK[m]1 | mithro: pong | 04:23 |
| shorne | mithro: it seems to be looking for stuf under, ./build/conda/x86_64-conda_cos6-linux-gnu/ | 04:24 |
| shorne | but libs get installed under ./build/conda/lib | 04:25 |
| shorne | ok, I am going to remote verilator and these toolchains for now | 04:28 |
| shorne | need to work on something else | 04:28 |
| mithro | shorne: I have to run too | 04:34 |
