<wens> ssvb: i took a quick look at sun6i dram vs rk3288
<wens> register names indeed match up
<wens> however the rk3288 does not cover the dramcom and mdfs blocks
naobsd has quit [Quit: Page closed]
<ssvb> wens: rk3288 code is very useful because they are defining a lot of constants (even though they are even not using all of them)
<ssvb> wens: and the allwinner code is full of magic constants
<wens> i did a bit of experimenting on a31/a23
<wens> a bunch of stuff needs to be enabled before the dramctl is available
<wens> otherwise poking it seems to hang
<wens> i didn't finish it though
<wens> basics are clocks (pll5, mbus, ahb1_sdram, mdfs?), bring dram controller out of reset, phy dlls
<ssvb> does the code from allwinner work?
<wens> afaik hans tried sun6i_dram.c in u-boot, and yes it worked
Akagi201 has quit []
<wens> he didn't finish integrating it though
<ssvb> if we have something, then it can be cleaned up and improved
<wens> i've added the link to boot0/1 dram init sources, which is more complex than sun6i_dram.c
<ssvb> thanks

<megal0maniac> Hi all. I'm having an issue with an A20 board (Itead IBOX, similar to cubieboard2). When the display sleeps, it won't wake up again. The device is still on and reachable over SSH, but the display doesn't wake up. Is this a known-issue? It sounds familiar
Quarx has joined #linux-sunxi
hipboi has joined #linux-sunxi
<libv> megal0maniac: did you try looking at our wiki?
<libv> megal0maniac: given that it's been 16 minutes, and you still haven't said "oh, right, it is on the wiki", i assume that you haven't, even though the end of your own question should've lead to that
<rellla> megal0maniac: typing a simple "display" in the search box of our wiki leads you to a possible solution.
<rellla> and yes, it's probably a (solveable) known issue
<libv> dpms on disp is pretty broken
<libv> sunxi_kms is solid that way
<libv> but some bastard still hasn't released it.
megal0maniac is now known as Guest49027
Guest49027 has quit [Killed (holmes.freenode.net (Nickname regained by services))]

<rellla> aka libv
<libv> libnand first, killing peoples nand contents really cannot be allowed to take place
leviathanch2 has joined #linux-sunxi
<libv> once all is known about that, and once the new device support strategy takes shape, all libnand drivers for which we have no source should get disabled in the kernel config
avsm has joined #linux-sunxi
<megal0maniac> I did try looking at the wiki, but it's difficult to find something if you don't know what you're looking for. I haven't spent the last 20 minutes hammering away at this because it isn't urgent, I just thought I'd ask in passing here because I was here already and it would take less time for you to point me in the right direction than to bash me for "not using the wiki"
<megal0maniac> I'm going to assume (given that I don't actually know what I'm looking for) that it has something to do with the framebuffer blanking timeout.
<megal0maniac> My understanding of framebuffers tell me that this can't be the cause, but not everybody knows everything.
<megal0maniac> And I will try that solution when I get back to that.
<libv> megal0maniac: so did a search on framebuffer not lead you to display?
<rellla> megal0maniac: yes, i'd try the framebuffer blanking tips first
notmart has quit [Quit: notmart terminated!]
<megal0maniac> libv: I didn't search for framebuffer because I don't fully understand what a framebuffer does. This is my point - it's probably easy to find if you understand the stuff, but I don't, which is why I ask here. For example, right now, I'm trying to disable the fb screensaver, but I need to change a kernel parameter and I don't know how to do that. So now I'm trying to figure out what that is, so that I can change it, so that I can (possibly) fix
<megal0maniac> Whereas if I throw out my question, and you say "oh it's that, try doing this" then I learn something and don't waste half a day reading 99 pages I don't need to and 1 which I do.
Quarx has quit [Quit: KVIrc 4.2.0 Equilibrium http://www.kvirc.net/]
<megal0maniac> I've added consoleblank=0 to the args in boot.cmd and I'll see what happens
<rellla> megal0maniac: You have learned how to manipulate kernel parameters onthefly ...
<megal0maniac> rellla: Have I? I'm not even sure that I've changed anything
<rellla> [15:34] <megal0maniac>I've added consoleblank=0 to the args in boot.cmd and I'll see what happens
<rellla> ??
<megal0maniac> I know what I've done, not necessarily what it means. But I'll take your message as confirmation. Thank you

<quitte> ddc: Hi.
<ddc> quitte: Hi
<quitte> I guess I can make some time right now
<ddc> quitte: appreciate that
<rellla> megal0maniac: you can also use a uEnv.txt . It's plaintext and hasn't to be rebuilt. I recognized, that wiki is really really messed up regarding boot.cmd and uEnv.txt
<rellla> it's no good idea to edit boot.scr with a text editor ... :p
<megal0maniac> I suspected that, but thought I'd try anyway. After the binary header, the rest is plaintext. This page was helpful: https://github.com/linux-sunxi/u-boot-sunxi/wiki
<ddc> quitte: Can you start a private, I don't want to spam the board

<megal0maniac> rellla: Is it not possible for the framebuffer screensaver to be interrupted by a keypress?

hipboi has joined #linux-sunxi
<libv> ddc: please, keep it in here, we all might learn something
<nove> megal0maniac: by what was said a bit earlier, dpms (the display sleep, wakeup) is broken in sunxi 3.4
<libv> ddc: plus, otherwise i might not get my opportunities to make put downs :p
<libv> honestly though: if this is a sunxi problem, keep it in here, others might be able to help, or if not, things can be shaped so they can fit into the wiki
<libv> megal0maniac: ...
<megal0maniac> libv: Yes?
<libv> megal0maniac: so hdmi dpms used to work, but doesn't anymore now?
<libv> because you did something wrong with your boot.scr?
<megal0maniac> libv: Absolutely nothing has changed
<libv> nothing you can spot right now.
<megal0maniac> I added consoleblank=0 to boot.cmd, built boot.scr from that and it still goes into a 'coma'
<libv> megal0maniac: check dmesg
<libv> is that command line at the top?
<libv> or near the top anyway
<megal0maniac> libv: No, I appended it before {extra}
<megal0maniac> Most recent dmesg is [ 941.383798] disp clks: lcd 148500000 pre_scale 1 hdmi 148500000 pll 297000000 2x 0
<megal0maniac> Which just looks informative
leviathanch2 has joined #linux-sunxi
<libv> megal0maniac: nono, iirc, the command line arguments are printed as one of the first lines of the device booting
<megal0maniac> Yip, it's there
<megal0maniac> [ 0.000000] Kernel command line: console=tty0 console=ttyS0,115200 hdmi.audio=EDID:0 disp.screen0_output_mode=EDID:1280x720p60 root=/dev/mmcblk0p2 rootwait panic=10 consoleblank=0
<megal0maniac> nove: Thank you, btw
<megal0maniac> So I'm abandoning the approach of fixing this, and rather trying to disable display sleep entirely as a workaround

<wens> hmm, found another brand of aw/rk devices, called waxberry
<hramrach_> waxberry
<hramrach_> that does not sound too yummy
leviathanch2 has joined #linux-sunxi
<hramrach_> wens: also it does not help much that there is a web page (maybe) claiming that such device is selling unless somebody has it, htere are readily available reviews, etc
<hramrach_> waxberry search gives some Chinese plant
<wens> that seems to be a mistranslation
<hramrach_> no, that seem to be perfectly fine results for the word waxberry
<wens> wikipedia seems to disagree
<hramrach_> if the brand is Chinese and is not searchable in English then write it in Chinese
<hramrach_> oh, it's commonly used incorrect translation of a Chinese fruit
<hramrach_> whatever
<mnemoc> 杨梅 ?
<hramrach_> that looks like the fruit, yes
<hramrach_> bayberry or whatever
<hramrach_> but where are the waxberry devices?
<hramrach_> raspberry pie ..
<hramrach_> ok, given the title the board id probably actually named 杨梅

<hramrach_> for the board size it gives good features I guess
<hramrach_> but sounds a bit expensive and the manuals are in .. Chinese
<wens> they also have a31s hdmi sticks...
<hramrach_> also spec says Ethernet but there is no connector ..
<wens> hehe
<wens> sales team needs some work
<hramrach_> or maybe I misread something. cannot find where it was said in the specs
<hramrach_> there - LANx1 interface
<hramrach_> and Serail port ;-)
bengal has joined #linux-sunxi
<hramrach_> well, no need to bash it for wrong spelling but does not look particularly awesome either way

<hramrach_> maybe iFive with the English site giving 404 is better. At least you know you have to read it in Chinese or look elsewhere
<hramrach_> btw there is a listing of iFive Allwinner A13 tablet on Aliexpress. After looking at the iFive website it seems they do rk exclusively and hence the A13 one must be a fake
