(I should have recorded the AXP temp too :()
<oliv3r>
though that looks very accurate in itself to be fair

also temperature variation happens very very rappidly, going from 132 MHz to 960 MHz the temperature changes within seconds to 85 ish
<oliv3r>
the last few degree's happen much slower, but that's obvious
<oliv3r>
cooldown goes about at the same rate, about 1 min to get very close to its final temperature

ssvb: bah, i borked my test, turns out, lightdm was still active, and by killing it, temperature went up slightly (cpubburn gets to spend more cycles heating)
<oliv3r>
it's not a huge difference
<oliv3r>
like 0.5 - 1C
<oliv3r>
and probably only noticeable in the lower ranges

i got 30 MHz via sest_speed, but bogomips are around 408; i should have checked that before doing the last lot of frequencies.

How I get into FEL mode on A23 allwinner? Different from A20 there is no UBOOT_SEL (or BSP) pin, how the A23 datasheet says.
<ricardocrudo>
I found a post about a tablet that uses an A23 chip, someone said to hold a volume+ button. what is necessary to implement this solution or something similar?

wens: nm, I used spaces instead of tabs, just noticed :p

wickwire: /dev/disp doesn't seem to have any locking against concurrent access, and using dri and vdpau both change layers at the same time, sometimes things go randomly wrong
<wickwire>
jemk: thanks for trying, maybe it's just a very specific combination of configurations and/or code versions on specific packages
<jemk>
maybe someone with more disp knowledge could confirm this suspection
<wickwire>
jemk: yes, I admit I'm not that knowledgeable either on the subject
<wickwire>
for now, in my case specifically, I wouldn't consider it dead serious
<wickwire>
but as I've got Qt5 working on cubieboard as well as accelerated GStreamer,
<wickwire>
I'm trying to combine the two into one single graphical/video app
<jemk>
at least i could not find a problem in fbturbo or libvdpau, and the errors look like the layers wouldn't be turned off correctly
<Turl>
libv: he's asking it :p
<wickwire>
or at least be able to produce apps like that
<wickwire>
so I'll be really putting it to the test if/when I manage to combine gstreamer and qt properly
<libv>
Turl: patents are bullshit
<libv>
he's fully on the bs side here
<jemk>
wickwire: if you want to try you could patch the kernel and add some locking to see if it helps
<wickwire>
jemk: I'll have a look and see if I can help
<jemk>
wickwire: something like this, its untested and i don't think it's a good permanent solution, but to test: http://sprunge.us/VZSK
<wickwire>
jemk: thanks for this, I'll have a look as soon as possible and write back if I manage to get it working!

<wens>
ricardocrudo: the s character on your keyboard
<wens>
Turl: what? where?
<ricardocrudo>
wens: ah, ok, I got it. Thanks
<wens>
ricardocrudo: there is also the option of writing 0x5aa5a55a to 0x01f00108, and upon reboot, boot0 will go into FEL mode
<wens>
that is, if you have a working system to begin with
<Turl>
wens: one of the #reset-thing on the usb node I think. I noticed when I did 'replace 8 spaces with tabs' on my editor
<wens>
i see
<wens>
ricardocrudo: it's basically what uboot does when you trigger fel mode from it
<ricardocrudo>
wens: nice! How can I do the first deploy of u-boot?

Hi, does anyone know the difference betwin VDD-CPU and VDD-CPUS in Allwinner A23 or A31? I am developing a board with A23 from scratch and I can't find the information. The same VDD-CPUS apears on A31, but I also can't find the A31 User Manual on the internet, only the datasheet seems to be available. On the A31 EVB, witch I am using as reference for power scheme (similar PMU / AXP221 and AXP223), the VDD-CPUS comes from a LDO (AXP221-DC5LDO or ex
<rafaelMOD>
ternal LDO). Is there any problem with using a switched power on VDD-CPUS or do I have to use an LDO for higher PSR?
<nove>
rafaelMOD: join ricardocrudo and together ask allwinner for the reference design, sdk, datasheets, and all
