hitendrahi all, has anyone tried using a gps dongle with AGL on M3 board? If so, which one?14:24

dl9pfhitendra: most dongles exposing a tty device should work out of the box.  (but note there is no service binding using it right now)14:49

mranostayyeah i'd say 95% of GPS dongles are just UARTs15:14
mranostayusing standardish NMEA codes15:15
mdpjobol's https://github.com/iotbzh/af-gps-binding exists out of tree..but ultimately that needs integrated into a generic location services binding that handles multiple sources.15:22
jobolright15:23
jobolfulup proposed a layered arch for audio15:24
jobolcould apply here15:24
mdpright, similar situation as location data can be pulled from (based on industry best practice in mobile frameworks) at least BT, WiFi, and GPS sources15:25
joboldamn you're right15:26
mdpsomething for "the list" of APIs to be done for AGL..the list is long15:26
mranostaymdp: and AGPS from GSM towers15:26
mdpmranostay: correct15:26

mranostaymdp: of course the plus with a USB GPS dongle it is a discoverable bus :)16:04
mranostayof course pps support is impossible but that doesn't really matter :)16:04
mdplol16:05
mdpthe "discoverable bus" meme never gets old :)16:05
mdpmranostay: it would be even better if we had the actual automotive i/o boards for these baseboards (like kingfisher) instead of mucking with usb nonsense.16:06
mdpmranostay: at some point I'm going to put together a low-level unit test case that shows the SCO/isochronous issues I saw with m3ulcb's usb hci.16:07
*** ctbruce has joined #automotive16:07
mdpmranostay: another distraction after pyro stuff16:08
mranostaymdp:  USB really isn't fun ever :)16:09
mdpno, at least I'm not fixing it with a production line down in shenzhen..that's when it really sucks. beer story sometime ;)16:09
mranostaymdp: at intel i sat inbetween a USB maintainer, and a ACPI spec writer.. not sure who hated life more :)16:12
mdphehe16:13
mdpgah, I hated working on the rapidio spec..the technology, yay..spec and trade association politics...brrrrrrrr16:13

hitendramdp@, seems like af-gps-binding reads gps data stream from socket vs gps dongle shows up as serial port,17:27
mranostayhitendra: it reads it from gpsd17:29
mranostaywhich is pretty standard17:29
hitendrakool, is gpsd baked into AGL?17:30
mranostayseems not but i do see the recipe17:33
*** claneys has quit IRC17:35
hitendrayup, i see it too, meta-openembedded/meta-oe/recipes-navigation/gpsd17:47
hitendrabut its not there on the agl running on m3 board17:48
hitendrawonder why? missing dependency?17:49
*** jlrmagnus has quit IRC17:50
mranostaynot in a package group likely17:51
dl9pfhitendra: likely hasn't been added to a packagegroup, yet.  for quick try add18:09
dl9pfIMAGE_INSTALL += "gpsd"  to your conf/local.conf  .18:09
dl9pfAnd of course: patches to the packagegroups welcome!18:09
*** jlrmagnus has joined #automotive18:14

khemdl9pf: yes I got a mail notification18:58
khemI think you need something like https://github.com/varigit/meta-variscite-fslc/commit/e8b08164386ec1d39b0249015ca61861d1d4a69719:00
mranostaykhem: seems a bit hackish :)19:06
mranostaykhem: is the host gcc build natively in OE or is it using the host one of the system?19:07
khemits using from host19:13
khemon and off I have felt like we should build gcc for build host too19:14
*** ctbruce has quit IRC19:16
dl9pfkhem: the old u-boot is hardcoding "cc" ...19:18
dl9pftrue, HOSTCC19:19
khemhmm19:22
dl9pfi tried u-boot-mkenvimage-native19:24
khemYeah I see19:24
dl9pfshould I pass HOSTCC and use it as in your link above ?19:25
khemI think you could. For now I applied your patch but it would be better to adapt the patch I pointed to19:26
khemsend a follow up19:26
dl9pfsure, will do right away19:33
