| walzert | @smurray: thanks for your commit, the generator seems to work with my files. hope that I'm able to test these generated files in an low-can-service until the EG meeting tomorrow | 17:23 |
| smurray | walzert: good to hear | 17:23 |
| walzert | smurray: there is a small issue in the generator that could/should be fixed the two example json files are missing ' "version" : "2" ' | 17:24 |
| smurray | walzert: what's the impact of that? | 17:25 |
| walzert | the tests files are not able to be used. | 17:26 |
| walzert | "ERROR: Unhandled exception - type must be string, but is number | 17:28 |
| walzert | " because the geneator expect the version with a number | 17:28 |
| smurray | do you mean with the generator? I see no code in agl-service-can-low-level that ever looks at the version | 17:28 |
| smurray | okay, I didn't try regenerating all of the examples, only agl-vcar, as I'd assumed they'd match, guess that assumption was wrong | 17:29 |
| walzert | (as a string) | 17:29 |
| walzert | yes I mean the files in the generator | 17:30 |
| walzert | low-level-can-generator/tests/basic and signals.json | 17:30 |
| smurray | ah. I can update those, sure | 17:31 |
| walzert | okay thank you very much. | 17:32 |
| smurray | the command given in the CMake isn't particularly accurate now, there are no application-generated.cpp files in low-can anymore | 17:32 |
| smurray | realistically, the only useful test at this point is if it can regenerate agl-vcar or the other json files in low-can | 17:34 |
| smurray | those json files in low-level-can-generator are a bit trivial | 17:34 |
| walzert | smurray: yeah you are right. so transfer the agl-vcar to that? | 17:38 |
| smurray | walzert: I'm not inclined, tbh. If this stuff survives in the production profile, it'll need significant rework, actual tests can maybe be added then | 17:41 |
| smurray | walzert: AFAICT Toyota seem to be saying they will contribute a CAN stack, we'll perhaps hear more next week at the workshop | 17:42 |
| walzert | smurray: okay thank you. so going forward to the service, I have to copy my file in the plugins folder as default-signals.cpp or is there more to do?? | 17:48 |
| smurray | walzert: that's the easiest approach | 17:48 |
| smurray | walzert: if you did want to be able to switch between two different sets of messages, you'd need to tweak the cmake file in plugins to build another plugin, then it's possible to switch by tweaking the binding config json | 17:49 |

| fivel | i was thinking with Linux in general, but was starting with AGL as it seems to have the drivers in the kernel, whereas mainline 5.x doesn't mention it atm. | 19:47 |
| fivel | and the folks who wrote the MOST drivers appear to be involved with AGL | 19:47 |
| *** walzert has quit IRC | 20:01 | |
| *** vrubiolo1 has quit IRC | 20:04 | |
| *** walzert has joined #automotive | 20:04 | |
| *** walzert has quit IRC | 20:06 | |
| fivel | so hoping someone knows where I can go to find out how to make that work. | 20:30 |
| smurray | fivel: iirc, the MOST drivers made it out of staging in 5.7 or 5.8 | 20:48 |
| dl9pf | and before they're in the staging/unstable submenu | 20:49 |
| smurray | fivel: but I've not looked to see what docs there are in the kernel tree | 20:49 |
| fivel | ah, cool. | 20:49 |
| smurray | If AGL is anything to go by, if you're running the stack from a Linux host, you need the Unicens daemon to drive things | 20:50 |
| smurray | you'll probably need to get some direction from the Microchip developers, I suspect. I don't see them on channel, you may have to email them | 20:50 |
| smurray | or there's a AGL connectivity expert group call tomorrow, they tend to call into that | 20:51 |
| fivel | thanks. firstly I'll see if I can get a kernel to build with it. | 20:53 |
| fivel | then work out how to wire it to a MOST controller (I'm assuming its an I2C interface) | 20:54 |
| smurray | fivel: for AGL we've only used the USB adapters from Microchip, I've no idea what the chip on those does, tbh | 20:56 |
| *** Newami has quit IRC | 21:12 | |
| fivel | oh, do they have a MOST to USB adapter? I hadn't come across those. | 21:13 |
| smurray | fivel: yep. I can't find it right off on microchip.com. Note that they talk up the INICnet name more than MOST at this point | 21:17 |
| fivel | I've found googling for anything MOST is near impossible because of the clash with "most" :/ | 21:18 |
| fivel | its hard to find things | 21:18 |
| fivel | and its quite niche | 21:18 |
| smurray | fivel: I actually have old adapters at this point, they switch the physical layer / connectors after I got mine | 21:18 |
| smurray | *switched | 21:18 |
| fivel | do you use them with a MOST network yourself? | 21:20 |
| smurray | fivel: AGL uses them for an audio in some of the demo setups for tradeshows, e.g CES | 21:22 |
| smurray | fivel: I think this is where you'd get h/w from, but the USB adapters we were given for AGL don't jump out at me: https://www.k2l.de/products/ | 21:23 |
| smurray | fivel: we were using one of the SLIM amplifiers, but the connectors on that board are different than what I see on the ones in the SLIM category there | 21:24 |
| smurray | fivel: it'd likely be easier to just email Michael Fabry at Microchip and ask, or ping the AGL ml | 21:24 |
| fivel | thanks | 21:33 |
