<NiteHawk> the trivial commands like "ver" or "hexdump" of a few bytes do work however, though?
<swiftgeek> yep
<swiftgeek> at least ver
<swiftgeek> not sure what would be safe to hexdump on A33
<NiteHawk> hang on - with 0x42400000 you're reading DRAM, not SRAM. so you *did* initialize DRAM by loading and running SPL, right?

<NiteHawk> if you can read SRAM (e.g. "./sunxi-fel read 0x2000 0x1000 test.bin"), then I nevertheless suspect that DRAM isn't initialized

<swiftgeek> NiteHawk: that works
Leepty has quit [Remote host closed the connection]
<NiteHawk> then it looks as if FEL has trouble accessing DRAM...
<swiftgeek> i guess those devices using nand tend to brick themselves easily? xD

<swiftgeek> i guess i will need to fetch some firmware and move it to VM to flash
<NiteHawk> well... FEL is somewhat fragile, as it doesn't seem to do exception handling. so once the ARM cpu borks up, FEL is expected to fail (it will no longer return / respond to queries)

<KotCzarny> unrelated to linux-sunxi, but i've received package from ali
<swiftgeek> hmmm somehow i get keyboard working in uboot but not after booting archlinux (OTG, A33)
<KotCzarny> 2 months late, SOAKING WET
<KotCzarny> and it was waiting 1 week at post office and still WET
mhlavink has quit [Ping timeout: 240 seconds]

<plaes> did it work? :)
<KotCzarny> havent' checked yet
<jelle> what's inside the package?
<KotCzarny> waiting for things to dry a bit
<plaes> electronics, I assume:P
<KotCzarny> 2 relays, 18650 holder and voltage meter
<jelle> *ouch*
<KotCzarny> seriously, i cant imagine package history to be THAT wet after a week

<swiftgeek> usbid is on ph8
<swiftgeek> and ID is always pulled up
<swiftgeek> (well at least together with µSD card which works)
<swiftgeek> hmm i guess this could be a culprit in sun8i-q8-common.dtsi
<swiftgeek> &usbphy {
<swiftgeek> usb1_vbus-supply = <&reg_dldo1>;

<swiftgeek> can't tell though whether it is host or otg one
<KotCzarny> have you tried dumping android script.bin ?
<swiftgeek> yes
<KotCzarny> and comparing config?
<swiftgeek> well i cannot compare it it's device tree
<KotCzarny> you can use it as a hint source
<swiftgeek> i have only OTG on this device so can't realy tell
victhor has joined #linux-sunxi
<swiftgeek> KotCzarny: i do have schematics
msevwork has joined #linux-sunxi
<swiftgeek> most likely my issue is that i cannot tell otg from host in device tree

<MoeIcenowy> for host mode you also need to load g_* to work
<MoeIcenowy> this is a bad thing
<swiftgeek> ^^
<MoeIcenowy> but you'd admit it
<swiftgeek> can somebody add this to wiki
<swiftgeek> the best would be something of different colour to provide nice warning

INdek has joined #linux-sunxi
<swiftgeek> yep sun8i-reference-design-tablet.dtsi has it
<swiftgeek> can we add it to sun5i-reference-design-tablet.dtsi as well?
<MoeIcenowy> I think in sun8i-reference-design-tablet.dtsi it's disabled
<MoeIcenowy> gsl1680 needs some tweaks in dt
<swiftgeek> MoeIcenowy: that's quite important there are few chips to pick from
<swiftgeek> afair there was supposed to be something magic upstreamed that would auto-detect chip
<MoeIcenowy> there won't be such a magic
<MoeIcenowy> something is digitizer-specified
<swiftgeek> yeah but on one model
<swiftgeek> you can get like 3 different touch chips
<swiftgeek> (same board etc)
<swiftgeek> they just whack whatever was cheapest/more available
<MoeIcenowy> yes
<MoeIcenowy> I have seen many digitizers are sold with a touch chip on its FPC
<swiftgeek> well i didn't see those in Q8
<MoeIcenowy> yes
<MoeIcenowy> For allwinner tablets I only see this kind of configuration for my A31s Colorfly E708 Q1
<MoeIcenowy> other tablets I have seen this are Atoms
<swiftgeek> anyway that disabled portion is still nice to have
<swiftgeek> less change is needed to enable touch :P
|Jeroen| has joined #linux-sunxi
<swiftgeek> also wasn't there some kind of overlay for devicetree for even smoother config?

<MoeIcenowy> are your system on SD card?
<parazyd> yes it is
<parazyd> haven't put anything on the emmc
<MoeIcenowy> try to alter mmcblk0p2 to mmcblk1p2

<parazyd> indeed seems so
<parazyd> although now
<parazyd> [ 3.630708] EXT4-fs (mmcblk1p2): couldn't mount RDWR because of unsupported optional features (400)
<MoeIcenowy> I don't know the key to this problem
<parazyd> yeah i'm googling it already
<MoeIcenowy> maybe you should try to create your rootfs with mkfs.ext3, not mkfs.ext4
<MoeIcenowy> 3.4 kernel is tooooooo old
<parazyd> but thanks for the tip
<parazyd> this board has overheating issues with mainline
<MoeIcenowy> you can low down the boot frequency in U-Boot
<MoeIcenowy> but it must be admitted Banana Pi did a bad board design here
<willmore> Yeah, you're seeing options in a EXT4 that aren't supported by that old kernel.
<parazyd> willmore: meaning i made the filesystem with a recent e2fsprogs?
<parazyd> probably
<parazyd> MoeIcenowy: can you point me to some documentation on this uboot voltage control?
<MoeIcenowy> not voltage control
<MoeIcenowy> but frequency control
<willmore> parazyd, do what MoeIcenowy said and use EXT3. It's more likely to be compatable with an old kernel
<MoeIcenowy> the Banana Pi M2+ board supports no voltage control
<MoeIcenowy> this is weird
<parazyd> yeah it's an unusual board indeed
<Ke> IIRC using nouid32 mount option helped for me on ext4
<Ke> or option
<Ke> anyway ext4 is definitely recommended, just figure out what the feature is
<MoeIcenowy> I'm trying to criticize the guys from BPi ;-)
<MoeIcenowy> P.S. currently the new Banana Pi vendor is no longer Sinovoip -- a new company called BPi Technology (比派科技) is splited up from Sinovoip

<MoeIcenowy> P = Plus
<NiteHawk> MoeIcenowy: weren't they forced to transfer the "BPi" name to a non-profit intermediate as a result of the constant bickerings between LeMaker and SinoVoip?
<MoeIcenowy> NiteHawk: nope
<jelle> MoeIcenowy: this translates to a weird sentence: "Affordable board certainly can not make you comfortable with, probably white is such a meaning"

tkaiser has joined #linux-sunxi
<tkaiser> MoeIcenowy: Maybe 9 months ago I reviewed M2+ and said that I don't understand why they did not at least use SY8113B to switch between 1.1V and 1.3V. Then Lion Wang (SinoVoip CEO) said that it would be hard to source this IC. Later I realized that there is SY8113B on the board but they forgot GPIO regulation.
<MoeIcenowy> Ah-oh
<MoeIcenowy> tkaiser: another problem
<willmore> Face, meet palm. Palm, meet face.
<tkaiser> MoeIcenowy: I still don't get who does the ODM work (obviously not SinoVoip judged on how less they know about their own hardware) and who produces stuff. But also that doesn't matter that much.
<MoeIcenowy> what's the real voltage of VDD_CPUX on M2+ ?
<MoeIcenowy> on schematics it says 1.2V
<MoeIcenowy> on linux-sunxi wiki it says 1.3V
<tkaiser> MoeIcenowy: According to their schematic it's 1.2V but in reality 1.3V. Confirmed by super moron called @sinovoip in their forum.
<tkaiser> But of course they don't update schematic. And they don't kick out this guy responsible for all this mess (doing 'documentation' while giving a sh*t about correctness)
<tkaiser> MoeIcenowy: Several people measured and it's 1.3V. Anyway... simple conclusion: Stay away since it's not worth the hassles :)
<willmore> ^^^^
<MoeIcenowy> tkaiser: can BPi M2+ work properly without throttling at 816MHz?

<apritzel> parazyd: have you updated the dtb as well? Because that's where the fix actually is, you could have even used the old kernel image, IIRC
<parazyd> yep
<parazyd> hmm
<parazyd> wait

<agin_> jernej: hey there
<jernej> hi
<agin_> I wonder if we have any more clues on this Composite uboot thing
<agin_> funny that when I change the UI Enable Bit, the display doesn't blank
<jernej> sorry, no, I forgot to bring TV out cable
ErwinH has joined #linux-sunxi
<jernej> probably something in 2 days
<agin_> do you have the OPi Zero?
<jernej> yes, I have
Mr__Anderson has quit [Quit: Leaving.]
LargePrime has joined #linux-sunxi
<agin_> oh good
<jernej> but I rather develop on H3...
<agin_> you will have composite working in 2 days?
FrostyBytes has joined #linux-sunxi
<jernej> no, in two days I will have a cable :)
<FrostyBytes> what is the status of support of graphics on pine64?
<jernej> FrostyBytes: currently none
<agin_> jernej: My uboot as is has composite out on the Zero, but it's very green and messed up as you will see
<FrostyBytes> so howcome some distros (e.g., ubuntu) reportedly work with graphics on pine64?
<jernej> FrostyBytes: BSP kernel
ErwinH has quit [Ping timeout: 240 seconds]
<jernej> agin_: don't worry, I will take a look
<FrostyBytes> so noone has RE the BSP kernel to see how it initializes gfx?
<agin_> sorry FrostyBytes, I dont have a Pine64!
<FrostyBytes> agin_: I buy you one if you willing to do the work, haha
<jernej> FrostyBytes: My HDMI driver for U-Boot should work on A64 with minimal changes which would enable simplefb driver
<agin_> FrostyBytes: jernej is the video master though!
<jernej> but again, I'm waiting on a special cable :)
<FrostyBytes> simplefb would be a great starting point
<jernej> agin_: Not really, I just put together code from different sources :)
<agin_> yes jernej's HDMI should work.... with a bit of massaging?
<jernej> you mean on A64? Mostly clocks and proper addresses...
<FrostyBytes> I have zero skills at massaging silicon
<agin_> jernej: I noticed your HDMI code uses lcd_tcon1, but infact init's TCON0,
<jernej> heh, there is some confusion due to datasheet naming. I will try to make it less confusing
<jernej> in the future versions
<agin_> jernej: I might have some time to work on it this week
<agin_> do you have any tips?
<jernej> not really, just dig into BSP code :)
