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
<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
