10:05 | topi`_ | has anyone successfully used more than 1 UART on HB? |
10:20 | Humpelstilzchen | topi`: doesn't it only have 1 uart on the io headers? |
11:12 | topi` | Humpelstilzchen: indeed, but since the i.MX6 has several UARTs and they're muxable on those same output pins, I'd bet there is a way... |
11:13 | topi` | perhaps I have to wait for jnettlet to reappear :) |
11:16 | vpeter | topi`: Isn't this just a matter of defining new uart in device tree and set correct pins for it? |
11:20 | topi` | I'd guess so |
11:20 | topi` | but i'm not an expert on device trees |
11:21 | vpeter | let me show it. |
11:26 | Humpelstilzchen | topi`: I havn't found any and I checked all muxes |
11:26 | Humpelstilzchen | topi`: there is always usb.. |
11:26 | vpeter | topi`: this is for udoo - http://pastebin.com/e2XJwwjy |
11:27 | vpeter | You need to check if correct pins are available on some gpio pins. |
11:34 | Humpelstilzchen | the hb2 might have uarts |
11:35 | Humpelstilzchen | oh the solid-run homepage doesn't work |
13:12 | Gluino | what's the latest version of the kernel for the HB ? and where can i find it ? |
13:28 | Artox | Gluino: 3.14.53 is the latest that SR provides |
13:29 | Artox | other than that, mainline works too |
13:29 | Artox | https://github.com/SolidRun/linux-fslc |
13:29 | Artox | your favorite distro should ofc also have it |
13:29 | Gluino | so what's the difference between SR kernel and others ? |
13:29 | Artox | "others" |
13:29 | Artox | I can only talk about SR, and mainline |
13:30 | Artox | cause thats all I know |
13:30 | Artox | SR developers made sure that all hardware features work properly, and that the system runs stable. |
13:30 | Gluino | when i tried mainline, there were no device tree |
13:30 | Artox | and they made sure that all advertised features work, such as VPU, GPU |
13:31 | Artox | when I tried mainline, it worked |
13:31 | Artox | and there were |
13:41 | Gluino | ok, i'll try |
14:45 | topi` | Ignition fails, "couldn't resolve download.solid-run.com" in the debug dialog |
14:46 | vpeter | topi`: DNS problem on your computer? |
14:46 | topi` | oddly enough, "curl http://download.solid-run.com/" works on my macbook (connected to the same wifi) |
14:55 | topi` | I've had nothing but problems with Ignition, maybe I just need to flash a readymage image |
14:55 | topi` | readymade |
16:30 | topi` | I managed to install Debian/WHeezy from Ignition's offerings, but now I have a black HDMI screen after "successfully installing" |
16:30 | topi` | the U-Boot screen does appear normally |
16:31 | topi` | hm, the monitor is blinking, so there's no HDMI signal at all |
16:32 | Artox | topi`, did you install XFCE or CLI |
16:32 | Artox | if XFCE, jsut give it some time |
16:32 | Artox | first boot is slow |
16:37 | topi` | what?? CPU1: failed to boot: -38 |
16:37 | topi` | that's what I got on the serial wire |
16:37 | topi` | Artox: the CLI variant, but it started up now. for reasons pretty much unknown |
16:38 | Artox | good |
16:38 | Artox | so its an i1? |
16:38 | Artox | as far as I know (and I dont know much) its trying to boot all CPUs, until it fails, and then settles that all have been found |
16:39 | topi` | OK :) |
16:40 | topi` | darn the debian/wheezy is SLOW to boot compared to jessie |
16:40 | topi` | I've been spoiled by jessie :) |
16:40 | topi` | or bsically any modern Linux that has dropped ancient sysv init |
16:49 | topi` | what do I have to remember to take off in order to use the ttymxc0 from my application? |
16:50 | topi` | I need to talk to another module over UART. So I don't want interference from gettys etc |
16:50 | topi` | I took serial console off of /etc/inittab, but how do I disable kernel from writing to UART? |
16:58 | Artox | topi` check uEnv.txt |
16:58 | Artox | console=ttymxc0,115200 |
16:58 | Artox | you want to get rid of that piece |
16:59 | Artox | or so I think |
16:59 | Artox | make sure that a console=tty stays |
17:01 | topi` | right |
17:02 | topi` | the only good thing about the SD card is that you can just put it in your macbook and fix the damn uEnv.txt after screwing it up ;) |
17:07 | vpeter | topi`: Or you can use USB Mass Storage directly from u-boot :) |
17:13 | topi` | oh? |
17:13 | topi` | that'd be useful with the upcoming HB Edge when booting from its eMMC |
17:14 | vpeter | check if you have command named ums in u-boot. |
17:52 | topi` | it seems there are two UARTs identified by this kernel. ttymxc0 and ttymxc3 |
17:52 | topi` | I wonder where the latter is going... |
17:53 | Artox | 3 is going to Bluetooth, topi` |
18:41 | Humpelstilzchen | topi`: bluetooth |
