04:49 Artox http://www.adafruit.com/products/1287
04:49 Artox I wonder if this one'd do a good job
05:13 Artox its not touch
05:13 Artox but its really small
05:14 Artox and put on a stand, makes for a nice screen
05:14 Artox (if not for working on it, but at least for entertainment and testing
05:14 Artox )
09:19 RickHull how much desktop resolution can the i4pro push via HDMI? is there any way to run 2 displays?
09:22 RickHull ah, looks like 1920x1080 http://wiki.solid-run.com/MicroSOM_i4
09:26 jnettlet RickHull, by changing the clocking we can actually go up to 2560x1440. I haven't verified this on the CBi, but xobs has it running on his novena which is the same SOC
09:29 RickHull ah, cool. how is it changed?
09:45 jnettlet RickHull, This is for the drm driver, but basically just adding the proper pixel clock. https://github.com/xobs/novena-linux/commit/17ed10f9fb7eda1925d642dbed50dbed55889275
09:53 RickHull ah, I see. I'm running arch from about 6 weeks ago (via ignition)
09:55 RickHull one product I'm interested in, maybe to produce somehow, is a good mechanical keyboard with an embedded SoC
09:55 RickHull carry that around instead of a laptop, use local displays
09:56 RickHull maybe be able to plug into your tablet or phone in a pinch
09:56 Arto 09:56 * Artox votes for "Plug into tablet"
09:58 xobs 2560x1440 is a bit slow, but it does work :)
09:59 RickHull 30Hz? 1920x1080 runs at 60 right?
09:59 RickHull or slow in terms of the GPU pushing more pixels?
10:00 RickHull Artox: need tablets that support being used as external display, first :(
10:00 Artox indeed
10:00 RickHull or perhaps just use the kb/soc's bluetooth chip and present as bluetooth to the tablet's OS
10:00 Artox thats why I am voting
10:01 Artox else I'd jsut grab a hdmi->hdmi adaptor and plug the hb in
10:03 xobs I don't have accelerated video working yet, so it's using software to draw 2560x1440. And also 1920x1080 to the internal LCD running on the LVDS ports.
10:08 RickHull xobs: able to run both simultaneously? can both be accelerated? can cubox use LVDS?
10:08 malte the cubox aint got a lvds port
10:09 RickHull headers even?
10:09 jnettlet HB only supports single channel LVDS so up to 720p
10:09 jnettlet maybe 1440x900 if you push it
10:09 RickHull i saw 1920x1200 somewhere
10:09 RickHull here wiki.solid-run.com/MicroSOM_i4
10:10 jnettlet that is if you have dual-channel lvds setup.
10:10 RickHull oh
10:10 jnettlet the microsom can drive that but none of the current hardware supports it
12:26 MarcusVinter jnettlet, Thanks for that. I'll give it a shot now :D
12:31 jnettlet k
12:57 bedlore Hi Guys
12:58 bedlore I got a cubox-i4pro which may have an ethernet problem
12:58 bedlore I loaded up openelec (5.0.2) and most boots no ethernet connection appears
12:58 bedlore wifi works fine but is too slow of course
12:59 bedlore how do I diagnose if the hardware is faulty?
13:01 bedlore I suspect its over heating
13:02 dz0ny bedlore: connect it to pc/router and observe ethernet port :)
13:02 bedlore I let it cool down before restarting and now its working again
13:02 dz0ny noramly two leds on router pc/blink
13:02 bedlore when its not working there is no led activitiy
13:03 dz0ny sounds like hw issue
13:04 bedlore I read something about giga-speed issues, but that doesn't result in the interface dying all together right
13:04 dz0ny yep
13:04 MarcusVinter jnettlet, thank you very much. worked like a charm :)
13:04 dz0ny bedlore: in any case, when it happens next time
13:05 bedlore is their a command from CLI I can watch for errors or info
13:05 dz0ny attach dmesg output
13:05 dz0ny $ dmesg will output kernel errors among other things
13:06 bedlore ok. so its working now, should I tail dmesg and make it work hard to see if it fails with a message?
13:06 dz0ny if device goes poof it should display something there
13:06 dz0ny mhm
13:06 bedlore hmm, where does openelec keep the dmesg log, can't find it to tail
13:06 dz0ny you enter dmesg :)
13:07 dz0ny or /var/log/syslog i think
13:07 bedlore nope
13:07 bedlore oh maybe..
13:07 bedlore no, no syslog in openelec
13:08 dz0ny I have no idea what openelec uses these days
13:08 dz0ny sry
13:08 bedlore probably just in memory
13:08 dz0ny anyway dmesg is your friend
13:11 bedlore CPU temp currently 43 C
13:14 dz0ny hm thats normal i think
13:14 dz0ny hell my HDD is hotter :D
13:15 bedlore ok, can't get it to fail now :(
13:15 bedlore maybe not putting on top of my amp is helping
13:15 bedlore gets hot up there
13:49 jnettlet MarcusVinter, excellent. Just let me know if there is anything else I can help out with.
13:51 MarcusVinter Thanks buddy. I think we're almost there now, looking great :)
