<jas-hacks_> hste: Got another GK802 to play with ;)
<hste> jas-hacks_: nice :) what cpu on this?
<hste> jas-hacks_: someone donated it? or accept to order one from boss at home? :)
<jas-hacks_> hste: Same as my old one, but its behaving differently it doesn't switch 1680x1050 resolution. Tries to goto 1080 instead
<hste> the hdmi part is strange...
<jas-hacks_> hste: its donated but looks used
<hste> jas-hacks_: have u compared wolfgar's wandboard kernel with your gk802 kernel?
<jas-hacks_> hste: I'm not expecting any differences, although he had problems with DMA.
<hste> jas-hacks_: "Set iMX6DQ/DL max speed back to 1GHz" is one for me I think

<hste> jas-hacks_: I got this one rtl8192cu:rtl92cu_init_sw_vars():<0-0> Failed to request firmware! on the 4.0.0 kernel now
<hste> using the wandboard rootfs
<jas-hacks_> hste: did you try my rootfs
<hste> jas-hacks_: using 3.0.35-02874-g0f6602f-dirty
<hste> jas-hacks_: yes I tried that before, and it worked
<hste> jas-hacks_: nice to have u back in buisness btw :)
<jas-hacks_> hste: good to be back
<jas-hacks_> hste: Have put one of there heatsinks (the big one) on it http://www.ebay.co.uk/itm/290928301990?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

<hste> jas-hacks_: and temp is ok with it?
<hste> jas-hacks_: its about the size of mine
<jas-hacks_> hste: Since I can't get the resolution to 1680x1050 its difficult to run my old test. Need to workout how to overload the GPU at 720p
<hste> jas-hacks_: why is that a problem?
<hste> jas-hacks_: u can start many tests from the terminal at once with glmark2&;tuturial7& etc
<obinou_> jas-hacks_: \O/ I got 2 GK802 . Overheat problems through
<obinou_> I'm not very happy with the foam between the case and the IMX - look very cheap to me
<jas-hacks_> obinou_: Yes the SOC looks like a 'cheap' version although it seems to have a metal lid. It's apparently the "whitebox" version what every that means
<jas-hacks_> obinou_: best to get a heatsink
<obinou_> mhhhh ok - mine doesn't have the metal lid : The foam is directly on the green chip
<obinou_> I was wondering on how to replace this piece of foam
<jas-hacks_> obinou_: if you remove the foam, what does the soc look like?
<jas-hacks_> obinou_: can you read the part number
<obinou_> (I also have a sabre light, so I can compare
<obinou_> yes
<obinou_> hold on
<jas-hacks_> The sabre light has the 'lidded' version which I guess should be much better
<obinou_> SC60888YM10AC , SBAH1241 , X0AHSBJ
<jas-hacks_> I have the same one
<obinou_> I think I'll just let it openned with a big heatsink. However I recomedded it for other, non-geek people, and for them , form factor was a plus .
<jas-hacks_> obinou_: I have re-placed the foam with a copper shim + a southbridge heatsink.
<obinou_> mhhh ok
<obinou_> within the original metal case ?
<jas-hacks_> obinou_: You could try replacing the with just a copper shim + casing
<obinou_> I'll try that
<jas-hacks_> but casing may get hot
<obinou_> even with the foam , the case gets rather hot
<obinou_> so yes I think it'll be worse
<hste> I saw someone added a coopershim on top of the foam to get it well connected to the alu-case
<hste> I use the foam under my heatsink. I think the "foam" leads heat well
<jas-hacks_> foam is not very conductive, so I expect copper shim to be better on its own. Alternative is a 5v fan http://smg.photobucket.com/user/371/media/GK802HS.jpg.html
<obinou_> interesting, since I happen to have some left from another project. Are them efficient ?
<jas-hacks_> obinou_: the fan?
<obinou_> yes
<jas-hacks_> The guy cut out a hole from casing for better airflow.
<jas-hacks_> and claims it works well.
<obinou_> ok
<obinou_> thanks for the info.
<obinou_> I have no time to work on this now, but I work on i.mx6 for my payday job (on phytec modules) .
<obinou_> so I hope I'll be able to help in the future
<jas-hacks_> the imx6 phytec module is very small
<obinou_> I did not had it in hand yet - it's supposed to come in a few weeks from our provider. I currenlty work on sabrelite
<jas-hacks_> Does sabrelite get hot under load?
<obinou_> yes, but nothing unbearable (you can keep your finger on the metal plate)
<obinou_> I do load it especially with float calcullation (opencv)
<jas-hacks_> obinou_: Are you designing your own board or just using others?
<obinou_> We are designing our own daughter-board for the phytec module (for a civilial drone)
<obinou_> with heavy width , and power constraints
<obinou_> and weight also of course
<jas-hacks_> obinou_: ... that sound interesting ... don't need a realtime kernel
<obinou_> Currenlty no , since all the flight control is still offloaded on a separate, STM32-based autopilot , linked to the imx by a serial link
<obinou_> on the long run, yes, certainly
<obinou_> in fact that's the reason why I'm woking in this company
<obinou_> To adapt preempt-rt , or even Xenomai if needed, on this
<jas-hacks_> RAM size must be so limited STM32?
vstehle has quit [Ping timeout: 260 seconds]
<obinou_> jas-hacks_: yes it is - i'm not into the autopilot thing, my main task is on Linux and I don't really know STM32
<obinou_> but the autopilot now is somehow limited, so it's planned to replace it by the i.mx6 one day
<obinou_> but we will need much more evolved stuff, like CPU partitionning and alike
<obinou_> to keep the realtime stuff usable (maybu with fastirq ? )
<jas-hacks_> obinou_: nothing like a challenge, will be good to know how you get on
datagutt has joined #imx6-dongle
<hste> jas-hacks_: I compiled your 4.0.0 kernel with 1Ghz hack and vpu 352. System running normal when only doing gpu stuff. Heat up to 70 and down to 66
<obinou_> jas-hacks_: will let you know - but I don't expect to work on that part until october
<jas-hacks_> hste: With 352 is it any better?
<hste> jas-hacks_: looks same to me. Havn't tested totem with a movie.
<jas-hacks_> hste: I think the 352 is more for video throughput
<hste> I thought it might rized voltage so it should get warmer, but temp looks same
<hste> jas-hacks_: but lowest cpufreq is now 352000
<hste> jas-hacks_: as describe in one of the comments on https://community.freescale.com/thread/309304
