| fury | That’s starting to sound like an AGL issue...hmm. Lemme ssh into my build server and see. | 00:19 |
|---|---|---|
| fury | Hmm. Seems like it got past that step but I was building for porter since that was my most recent build. Haven’t done qemu in a while. I’ll try that one | 00:37 |
| fury | hmm, libhomescreen failed :/ | 00:50 |
| LoveMHz | fury: Thanks | 00:50 |
| LoveMHz | Seg fault? | 00:50 |
| fury | | Could not find qmake configuration file linux-oe-g++. | 00:50 |
| fury | different than the one you failed on, think this is earlier in the process than that | 00:51 |
| fury | I could swear I ran into an issue with libhomescreen once before and I worked around it O_o | 00:52 |
| fury | about 3 weeks ago cause i have that exact error in my pastebin account | 00:55 |
| fury | well, dunno how i worked around it...guess i didn’t O_o | 00:58 |
| fury | hope a bitbake –continue agl-demo-platform resolves it. oh boy iOS 11’s new auto-em dashing is going to make it really annoying to type commands into an SSH client | 01:02 |

| fury | Hi! How’s it hangin? | 01:41 |
| akilaw | fine | 01:41 |
| akilaw | the pastebin output is not for my PR right? | 01:42 |
| fury | Right. I’m trying to build AGL for qemu to see if there’s a problem causing segfaults in the compilation | 01:42 |
| fury | And I keep running into other things :D | 01:42 |
| akilaw | can you see this | 01:42 |
| akilaw | Here is the PR https://github.com/GENIVI/genivi-dev-platform/pull/97 I added zebra recipe | 01:43 |
| fury | I see it :D | 01:45 |
| fury | I wish I knew enough about GDP to be able to comment. I haven’t used it. Prolly should | 01:46 |
| akilaw | its ok <fury> | 01:48 |
| fury | gah. Looks like I have to delete my build folder and start over again | 01:52 |

| LoveMHz | I was about to say don't look at me. I'm just a web dev guy with a EV car project haha. | 02:02 |
| akilaw | oh really | 02:03 |
| LoveMHz | 75' Datsun 280Z conversion. | 02:04 |
| akilaw | my story is also similar to yours | 02:04 |
| LoveMHz | awesome. any details? I'm just starting but eager to hear anyones story on the subject. | 02:06 |
| akilaw | I worked on electric car project | 02:07 |
| akilaw | its a high performance electric car | 02:08 |
| LoveMHz | nice, I wanted to do something a bit more but looks like I'm going with a single Warp9 and simple battery set up. maybe next time. | 02:10 |
| fury | LoveMHz: my build of qemu worked, may be the Ryzen thing. You might try pinging the mailing list to see if anyone else has tried it and/or worked around it | 02:13 |
| fury | I had a bunch of old temp files laying around that were breaking my build, once I blew away the directory and reinitialized it, it brought everything over from the sstate cache and everything was fine | 02:13 |
| LoveMHz | I'll try it on another system first. Would hate to bother anyone on the list because of a possible CPU issue. | 02:13 |
| fury | On the contrary, not a bother, it’s another data point that may help track it down and fix it | 02:14 |
| fury | Or at least save someone else some head scratching wondering why their fancy new setup is failing | 02:15 |
| fury | Someone with more knowledge of yocto or AGL might have some ideas | 02:16 |
| LoveMHz | That's true. | 02:16 |
| fury | Does seem strange to me that it’s always that same recipe. I woulda thought if it was the Ryzen bug that it’d just be randomly failing all over the place | 02:21 |
| LoveMHz | Maybe it's Ubuntu then. | 02:22 |
| fury | Could be. I’m rocking 16.04 with no problems. You could rule that out by trying the AGL SDK Docker image; I think it contains all the necessary things to build an image | 02:24 |

| fury | https://github.com/iotbzh/xds-server/blob/master/README.md#how-to-run | 02:29 |
| *** JordonWu has quit IRC | 02:29 | |
| fury | do everything up to `bash ./xds-docker-create-container.sh 0 docker.automotivelinux.org/agl/worker-xds:3.99.1` - skip the xds-server stuff unless/until you get a working image building environment. (Or you could try downloading one of the snapshot builds for qemu, if you don’t want to customize the image and just want to run it/use the SDK) | 02:31 |
| LoveMHz | No idea what I want to do, but I'm thinking I'll have to do a bit more than just app development. | 02:33 |
| fury | But I’m not very familiar with how to run the qemu images - I’ve pretty much always run it on bare metal (Raspberry Pi, Porter, even wandboard back when that thing worked) | 02:33 |
| fury | Yeah, if you want to change which drivers are built, or customize one of the built in demo apps, you’ll definitely have to have a custom image (I’m juuuust starting to get pretty familiar with how to do that, and I’ve been farting around with AGL on and off for a couple years :) | 02:34 |
| fury | Sometimes I learn slow tho | 02:34 |

| fury | smurray: just a heads up, i added a jira issue for that whine i'm hearing in the radio, with all the research i've done so far... haven't tracked it down but basically, the rtl_fm command line works fine with a sample rate of 256000. https://jira.automotivelinux.org/browse/SPEC-708 | 18:47 |
| fury | dunno if you wanted it to be assigned to you or me (since i'm prolly the only one that hears it :D) | 18:47 |
| fury | i'm not quite sure how i'd submit a change to the gerrit for the radio app... i do repo upload for the main repository | 18:49 |

| smurray | fury: you'd do a "git review" in your clone of the radio app. I'm not sure I'd really want the sample rate to be configurable, tbh | 20:50 |
| fury | Yeah I just did it to figure out if there was a setting that worked better. As far as I can tell, raising it just makes everything quieter and doesn’t get rid of the whine (whereas it does on the command line O_o) | 20:51 |
| smurray | fury: I'll experiment some. In my tests with the command-line program I never got rid of it in my setup | 20:52 |
| smurray | fury: cheap dongle plus the hack that is rtl_fm is unlikely to result in great performance, I suspect | 20:52 |
| smurray | fury: once I've got a few other JIRA issues cleared, I can tinker with GNU radio on a desktop and see if it can do better with the dongle than rtl_fm can | 20:54 |
| smurray | fury: when I've played with gqrx and the like in the past, FM radio was kind of crap as well, so I'm not sure | 20:55 |
| mranostay | smurray: yeah rtl-sdr isn't really meant for analog signals | 20:55 |
| mranostay | smurray: wonder if "HD radio" would work easily | 20:56 |
| fury | smurray: cool, no big rush, I’m just sitting here kinda dumbfounded I have a different experience with the rtl_fm command line utility than with the radio app which as far as I can tell is using the same code | 20:56 |
| fury | HD radio would be fun | 20:56 |
| mranostay | but i suspect that is only an North America thing | 20:56 |
| fury | yeah, it’s DAB elsewhere right? | 20:57 |
| mranostay | no clue | 20:57 |
| mranostay | fury: which antenna do you have anyway? | 21:00 |
| mranostay | telescopic or the little duck antenna | 21:00 |
| fury | Big telescoping one. Few feet long | 21:01 |
| mranostay | fury: could adjust it to 1/4 or 5/8th wavelength to see if that helps | 21:02 |
| fury | Hmm. How long’s a wavelength? | 21:02 |
| fury | I did fiddle with the length of the antenna quite a bit trying to pick up signal better but didn’t hear any change in the noise | 21:02 |
| mranostay | ah nm then | 21:03 |
| fury | Big metal building, surprised I even pick up the 3 stations that I do :P | 21:03 |
| smurray | mranostay: HD radio is still very experimental in GNU radio AFAIK | 21:04 |
| mranostay | fury: ah yeah if you have metalized windows that will be a problem | 21:04 |
| mranostay | in my old flat i couldn't get gps or ADS-B traffic at all | 21:04 |
| smurray | fury: note that my rtl_fm_init function might end up tweaking the params differently than the command-line tool | 21:04 |
| mranostay | smurray: if i remember correctly even traffic data is TDM sent over HD radio as well | 21:06 |
| fury | smurray: I looked line by line between command line main and rtl_fm_init/play, didn’t see a whole lot of difference | 21:07 |
| fury | init & start rather | 21:07 |
| mranostay | smurray: how much cpu does rtl_sdr take to decode audio? | 21:07 |
| smurray | mranostay: iirc something like 15% of a core on porter | 21:08 |
| smurray | mranostay: it's not something you'd ever ship in a real car | 21:08 |
| mranostay | ah better than i would have thought | 21:08 |
| mranostay | but yeah | 21:08 |
| smurray | mranostay: at least w/o getting better quality, etc. for that much cpu | 21:08 |
| fury | it’s pretty light, until I cranked up the sample rate to 1m lol | 21:09 |
| fury | But yeah. I wonder if there’s a better off the shelf USB dongle I could get | 21:09 |
| mranostay | fury: meh they are all the same really | 21:09 |
| mranostay | only issue is i've noticed they overheat and the PLL loses lock | 21:10 |

| *** joone has joined #automotive | 21:12 | |
| mranostay | fury: yeah there are some that are FM radios that you configure over i2c but get audio in | 21:13 |
| mranostay | very low overhead esp if you have a audio codec that route it directly | 21:13 |
