| 11:49 | topi` | Artox: is it possible to build the SR debian image in such a way that there will be DTB's for both the Dual/Quad and the Solo variants? |
| 11:49 | topi` | and choose between the dtb's in UBOOT |
| 11:49 | topi` | right now, I get lots of errors about missing processors, missing Audio etc etc |
| 11:50 | topi` | (this on a HB Gate / Solo) |
| 11:51 | topi` | and if I would get a suitable example .dtb from jnettlet that enables my RS485 click board, then I'd be all set :) |
| 11:51 | jnettlet | topi`, this is a problem with device-tree and linux and still exists upstream as well. |
| 11:52 | jnettlet | we have started a discussion on it, but there isn't a simple solution for this, other than making enormous amount of device-tree files. |
| 11:52 | jnettlet | those errors, are harmless |
| 11:52 | topi` | yes |
| 11:53 | topi` | IIRC some older (like more than year old) debian image actually contained dtb's for both the Solo and Dual/Quad and chose between them at boot time? |
| 11:53 | topi` | of course, at that time there was only a single HB variant |
| 11:53 | topi` | I mean the baseboard |
| 11:53 | jnettlet | We have variants for the two families. One for the iMX6S/DL and another for the iMX6Q/D |
| 11:54 | jnettlet | and we do auto select in u-boot |
| 11:55 | topi` | yes, and this didn't work for my Gate since I got those "error starting processor N" messages |
| 11:56 | topi` | or maybe that always happens despite of the chosen dtb? |
| 11:56 | jnettlet | that is a kernel bug |
| 11:56 | topi` | OK |
| 11:56 | topi` | then let's not worry about it :) |
| 11:56 | topi` | can you point me towards a DTB that would allow me to send data via the RS485 click? |
| 11:56 | jnettlet | I need to backport rmk's fix. |
| 11:57 | topi` | sorry, I just naively assumed it was easily fixable by a correct dtb |
| 12:01 | jnettlet | topi`, it should just work. It should be available over uart3 |
| 12:03 | jnettlet | the device would be /dev/ttymxc2 |
| 12:03 | topi` | OK, I'll try |
| 12:03 | topi` | I'm also a bit new to the RS485 :) but what the customer wants, we (try to) implement it... |
| 12:04 | topi` | the Click stuff is great, we can even offer a backup GPRS modem via a Click board if customer wants it |
| 12:04 | topi` | what kinds of boards have folks at SR tested with the Gate? |
| 12:05 | jnettlet | https://github.com/torvalds/linux/blob/master/Documentation/serial/serial-rs485.txt |
| 12:06 | jnettlet | topi`, I have a handful of boards. There isn't a good way to do easy hotplug support. I have played around with device-tree overlays which is the way to go, but the userspace for that is very clunky |
| 12:06 | jnettlet | but pretty much everything should work because all the click boards have simple interfaces, spi,i2c,uart |
| 12:07 | jnettlet | it just may take some device-tree hacking |
| 12:12 | topi` | right |
| 12:13 | topi` | there's just very little documentation in the wiki for the Gate |
| 12:13 | topi` | but I guess you guys have hands full of stuff right now with all these new boards etc |
| 12:19 | jnettlet | topi`, yeah and the guys that handle most of that just started school again for the semester :) |
| 12:19 | jnettlet | I am slowly getting things caught back up |
| 18:04 | vpeter | mk01: Can I PM you? |
| 21:36 | ngochai | Hi guys, |
| 21:37 | ngochai | where can I find the official SPL and u-boot.img for my hummingboard pro? |
| 21:39 | Artox | ngochai: http://www.solid-run.com/wiki/doku.php?id=products:imx6:software:development:u-boot |
| 21:40 | ngochai | Artox, I can't find any link to download those files on that page |
| 21:43 | Artox | neither can I |
| 21:43 | Artox | but it isn't hard to build |
| 21:44 | ngochai | or is there a way to get those files from a Ignition sd card? |
| 21:44 | Artox | Wellllllll |
| 21:44 | Artox | not really |
| 21:44 | Artox | there is |
| 21:44 | Artox | but it isnt any easier |
| 21:44 | ngochai | I don't know the actual sizes of those file |
| 21:45 | Artox | neither do I |
| 21:45 | Artox | thats why it isnt easier |
| 21:45 | Artox | just build them? |
| 21:45 | Artox | or is that a problem? |
| 21:45 | ngochai | that's the problem :) |
| 21:45 | Artox | got a suggestion |
| 21:45 | Artox | extract them from debian |
| 21:45 | ngochai | how? |
| 21:46 | Artox | https://repo.solid-build.xyz/debian/jessie/bsp-imx6/armhf/u-boot-cubox-i_2013.10.1444737373-1_armhf.deb |
| 21:46 | Artox | if you manage to u8npack the .deb |
| 21:46 | Artox | you will have all you want |
| 21:46 | Artox | I need to get some rest now |
| 21:46 | ngochai | great |
| 21:46 | Artox | have fun |
| 21:46 | ngochai | thank you |
