| smurray | hitendra: the yocto default policy is to backport upstream fixes onto the version of OpenSSL that a particular yocto release shipped with, it is very rare that they would update it to a new version. If you need actual 1.02l, you'll need to backport the new recipe from the master branch of upstream | 00:26 |

| smurray | mranostay: rtl_fm and the derived code in the radio binding do not use gnu radio, but the custom hacked decoder that fury mentioned | 00:27 |

| hitendra | thanks smurray@, also fury@ pointed me to a post talking about some TP-Link wifi dongles use the Realtek chipset, my dongle seem to be the one, so i'm adding the drivers and testing to check if that's case, will confim it first thing tomorrow | 00:47 |
| hitendra | *some* dongle meaning the one we're using i.e. same as on ces demo 2017 wiki | 00:48 |
| chbae | FYI: hitendra: I updated openssl to opembedded-core and you can find 1.02l in master branch of openembedded-core. | 02:10 |

| CTtpollard | is the sdimg file from the ALG download server working for raspi3 or do I need to use the rootfs & uimage? | 14:37 |
| CTtpollard | *AGL | 14:37 |
| CTtpollard | do you know leon-anavi? | 14:37 |
| fury | the sdimg worked for me a week ago (master snapshot 07-06 b445) as did the dab rc2 release (3.99.2) but not sure if anything's changed since then | 14:38 |
| CTtpollard | cheers fury | 14:39 |
| fury | no prob :D | 14:39 |
| leon-anavi | CTtpollard, I am always building my own images :) | 14:44 |
| CTtpollard | leon-anavi: Yeh :) I just wondered if sdimg was still working, I thought I read something about switching to rootfs & uimage recently | 14:48 |
| CTtpollard | maybe I'm wrong, it is friday afternoon after all :) | 14:48 |
| *** jlrmagnus has joined #automotive | 14:53 | |

| nathani_ | thanks fury mranostay smurray. | 15:42 |
| fury | to actually answer your question, gnuradio might be a better thing to use for a higher quality demo, but I'm not sure that anybody would actually use an SDR, gnuradio or not, in production. so I guess it depends on how much work it'd be to change from using the rtl_fm based code to something based on gnuradio. If you'd like to fool around with the demo radio app to replace it, I'm sure patches are welcome :) | 15:50 |
| fury | I have an annoying high pitched whine in my case under the rtl_fm based demo radio, but I'm planning on replacing the SDR with a "real" tuner that can do more better | 15:52 |
| nathani_ | what real tuner are you thinking about? | 15:52 |
| fury | I could get rid of the whine from the command line version of rtl_fm, though, which is weird, cause passing the same parameters (or so I thought) doesn't do the same thing in the demo radio app | 15:52 |
| smurray | fury: I find the whine comes and goes on my setup, so who knows | 15:53 |
| *** akilaw has joined #automotive | 15:55 | |
| fury | I was prolly gonna start looking at any tuner that has a driver in the mainline kernel, http://elixir.free-electrons.com/linux/latest/source/drivers/media/radio | 15:55 |
| fury | cause I don't feel like writing a new driver :P | 15:55 |
| smurray | fury: mdp had some ideas, might be worth pinging him next week when he's back from vacation | 15:56 |
| fury | smurray: weird. when I listen through the command line it's almost pristine (I'm in a big metal building with horrible reception, surprised I get any channels) | 15:56 |
| *** CTtpollard has quit IRC | 15:57 | |
| fury | I compared the source code and I couldn't find any differences in how they worked, as far as the parameters that got rid of the whine on the command line utility | 15:57 |
| nathani_ | I did some testing the other day from the command line, i was able to get some reception, but nothing like my car radio | 15:57 |
| nathani_ | using a laptop and gnuradio, it was very comparable to my car | 15:58 |
| smurray | fury: I'll poke around some more, the configuration bit is a bit messy | 15:58 |
| smurray | nathani_: that's kind of an apples and oranges comparison, the rtl_fm decoding is purposely simplified to work on low-end h/w, a full gnu radio chain likely has better filtering | 15:59 |
| smurray | nathani_: the issue is you're not going to want to burn that much CPU to listen to the radio | 15:59 |
| nathani_ | absolutely | 15:59 |
| *** [AD]Turbo has quit IRC | 16:00 | |
| smurray | nathani_: there are many phillips and silabs AM/FM tuner chips, issue is none of them are available in a cheap, convenient form-factor | 16:00 |
| fury | this minnowboard turbot quad core is so beefy, though, might be fun to try gnuradio on it | 16:00 |
| nathani_ | yes, that's what i've found. hardly any even have demo boards. | 16:01 |
| smurray | fury: I have no doubt it'll work better, I even discussed it as a possible project for AGL with gnu radio folks at one point | 16:01 |
| smurray | fury: but it'd be likely easy to build something that had problems on rpi, porter, etc. | 16:02 |
| fury | yeah | 16:02 |
| smurray | it's the tension between viable demo and production software. No vendor will use SDR for AM/FM in a product | 16:03 |
| smurray | so the question is what's good enough for a basic demo | 16:04 |
| *** mfritzsch has quit IRC | 16:05 | |
| fury | I demoed AGL for a few minutes to the local OSS meet up group, turned on the radio for a few seconds then quickly went back to Bluetooth cause the ringing, think that probably qualifies as "good enough" | 16:06 |
| fury | one of them wants to put it in his car :P | 16:07 |
| fury | I'll have to add a section on "can you put it in your car?" when I make the full presentation. I've seen a couple people here and there who've wanted to do that, and there's lots of DIY car head unit projects out there | 16:11 |
| fury | obviously it's meant as a starting point for a product, but as-is, it's got just about all the things DIYers want | 16:12 |
| smurray | fury: mdp was looking at some of the diy carputer sites for radio h/w ideas, it's kind of slim pickings as streaming seems to have killed the USB AM/FM adapter market | 16:16 |
| smurray | fury: he had something in mind to experiment with, but I don't have a link handy | 16:16 |
| fury | Yeah, that was my thought too, most people with the wherewithal to do this have smartphones, smartphones have plenty of ways to get audio, I usually use Pandora or YouTube for music myself | 16:18 |
| fury | some of them even have FM tuners built into them lol | 16:18 |
| fury | or you can fake it with iHeartRadio in some areas | 16:19 |
| fury | would probably be even neater to have a reference implementation of SDL, from what I understand, that talks directly to apps like Pandora, Spotify, and iHeart Auto | 16:26 |
| fury | I think it's getting integrated into GDP for next release | 16:26 |
| *** claneys has quit IRC | 16:33 | |
| fury | man these random lockups are annoying...did I just happen to get a couple of dud boards or is there something that AGL is doing which it doesn't like that GDP is not doing? | 16:41 |
| *** toscalix has quit IRC | 16:42 | |
| *** jlrmagnus has joined #automotive | 16:44 | |

| nathani_ | I recently changed my e-mail that I'm using with git. Changing my gerrit contact e-mail and updating my ssh key, didn't seem to work. So I registered a new account. Does someone have to approve me in order to submit changes for review? | 18:51 |
| nathani_ | I'm still getting a permission denied (publickey) error | 18:51 |
| mranostay | pretty sure there is a settings field to add different emails in gerrit | 19:00 |
| nathani_ | I did try that first, but i got the key error. so i assumed the email was the problem | 19:01 |
| nathani_ | i'll ask simon? | 19:01 |
| mranostay | sometimes you'll have issues if your email doesn't match your systems username | 19:01 |

| fury | guess i got a couple of duds | 19:55 |
| fury | either that or two equally bad power supplies? | 19:55 |
| nathani_ | mranostay, yes git review is attempting to use my computer's username for login | 20:02 |

| *** jlrmagnus has joined #automotive | 20:21 | |
| fury | aaaaaaaaaaaaand agl locked up again. this time i have the debug option set in the boot args. but still nothing showing in the serial console except a bunch of these about every 90 seconds: | 20:24 |
| fury | [11351.077098] systemd-journald[167]: Sent WATCHDOG=1 notification. | 20:24 |
| fury | that was the last thing i saw | 20:24 |
| fury | https://pastebin.com/FhB1EjdY | 20:27 |
| fury | think the last thing i can think to try is to use a lab power supply with a 6A capacity, but given that the options they sold it with are 5v2a or 5v4a, i would think my 5v4a and 5v3a power supplies ought to work just fine | 20:29 |
| mranostay | fury: iirc 4A is good enough | 20:29 |
| *** jlrmagnus has quit IRC | 20:29 | |
| fury | yeah. i'm gonna try the same power supplies with my wandboards just to double check | 20:31 |
| smurray | interesting that the paclient segfaulted. Have you tried booting up with memtest86 and testing the memory? | 20:34 |

| fury | pinged the mailing list and contacted the vendor to see if they have the same issue, we'll see how it goes i guess | 22:23 |
| fury | smurray: thanks for the suggestion to try memtest, saves me from having to figure out how to get the wandboard going again :P | 22:24 |
| fury | or get another power supply | 22:25 |
| fury | with that pattern that the LSB is set to 00 or 01 in the tests that it fails, I guess as long as whatever OS doesn't use address 0 it'd be fine? | 22:26 |
