<TheLinuxBug>
I have followed http://linux-sunxi.org/Boot_Android_from_SdCard but the A10 will not boot, just sits there. Does this method work for the A10? Am I missing something easy here?
<mripard_>
not all of them, but GMAC, MMC and USB do, yes.

only spi uses ddma on demand
<MrBar>
very good
<MrBar>
now i can use ddma engine for my games
<MrBar>
mripard_, thanks a lot
<mripard_>
and so now not using ddma is actually good?
<mripard_>
seriously?

mripard_, i just found great project http://abyz.co.uk/rpi/pigpio/ they just handle pio with dma and i plan to port it on sunxi partially
nemunaire has joined #linux-sunxi
<MrBar>
mripard_, yes it hacky way to do it from kernel point of view
fredy has joined #linux-sunxi
<MrBar>
but how it useful? what you think about?
<mripard_>
I don't see what you can't already do through /sys/class/gpio
<MrBar>
mripard_, speed
<MrBar>
i plan to handle PIO ports directly an even with ddma
<MrBar>
and work at near bus speed
<mripard_>
you can't drive the GPIOs with DMA.

why not?

i can

MrBar: except that the PIO has no way to report to the DMA controller that it has something to transfer
<mripard_>
nor does it have any kind of FIFO that would buffer the data waiting for the DMA controller to fetch them
<MrBar>
yes there no support for interrupts planed
<mripard_>
it's not just interrupts
<mripard_>
there's no way to reliably extract data from the PIO using DMA
<MrBar>
mripard_, Continuous mode
<MrBar>
of dma
<MrBar>
we can get buffer then process it
<MrBar>
so i testing it now

Turl: I need the pll3 and pll7 because I need the HDMI controller to start working
<leviathanch>
so that the others from AW can fill in the gaps they do not have docs for
<leviathanch>
but first the controller needs to get a proper clock
<leviathanch>
Turl: does that mean I need to write my own clock driver first?
<Turl>
leviathanch: yeah
<Turl>
leviathanch: as far as I recall, no other clock has the fractional thingy
<leviathanch>
okey
<Turl>
leviathanch: btw, wy are you worrying about the clock? cant you get it to work with what uboot already did for you?
<Turl>
why*
iamfrankenstein has quit [Ping timeout: 250 seconds]
<leviathanch>
obviously it didn't work properly
<leviathanch>
because when I configure pll enable within the HDMI controller, nothing is working
<leviathanch>
there is a tristate at the clock input of the hdmi controller
<leviathanch>
but enabling/disabling it doesn't do anything
reinforce has quit [Quit: Leaving.]
<Turl>
leviathanch: but hdmi is working before your driver kicks in, right?
<leviathanch>
uhm
<leviathanch>
I'm using mainline u-boot...
<leviathanch>
does it have hdmi by now?
<Turl>
yeah, on sun4/5/7i iirc
<Turl>
(and by extension on mainline too, via simplefb)
<leviathanch>
hmm
<leviathanch>
okey
<Turl>
mainline linux*
<leviathanch>
it would be handy to have the ddc clock and hdmi clock and the pll3/7 in linux
<leviathanch>
in order to have the capability of changing the modes

<TheLinuxBug>
Okay, so is there anyone who can provide a good image for sdcard for Android for A10 or a link to where to get it to work right? I followed the wiki step by step but it never boots. The only thing I have been able to hack together so far is using Android release 1 from Olimex with the kernel from the android images provided for A10. However, it seems to have issue with ethernet a bit and also is lacking in the sunxi apps such as xbmc. If anyone has
<TheLinuxBug>
Either that or directions which work to create a good booting Android sdcard
* TheLinuxBug
has a hard time pondering why there isn't already one provided on the linux-sunxi wiki but he will take whatever he can get at this point :x

If someone can provide directions on making a good image I would also be happy to provide a permanent link to it on the wiki serverd from one of my servers, if that sweetens the deal any, lol

TheLinuxBug: Most people around here work on "normal"/"mainline" Linux; there are comparatively few people around here who work on android stuff.
<TheLinuxBug>
well I bought 3-4 of the boards without NAND on them
<TheLinuxBug>
and I had a buddy who wanted to use android
<TheLinuxBug>
unfortunately right now it seems the only 'easy' way to make android happen is in the NAND
<TheLinuxBug>
seems no one has ever made an sdcard image
<TheLinuxBug>
I would be happy with the default image in fact that comes with it
<mnr>
Sorry, no idea - I don't use android at all.
