<anarsoul> jernej: is there hdmi support in u-boot for H6?
<MoeIcenowy> anarsoul: there's some WIP thing
<anarsoul> MoeIcenowy: mainline u-boot incorrectly detects ram size on my board
<anarsoul> SPL says: DRAM: 4096 MiB
<anarsoul> but u-boot later:
<MoeIcenowy> anarsoul: one or forever?
<anarsoul> DRAM: 2 GiB
<MoeIcenowy> once *
<MoeIcenowy> and is your board 4GiB ver?
<anarsoul> yes
<jernej> anarsoul: that's notmal, since algo in U-Boot proper detects only power of 2 sizes
<MoeIcenowy> oh 3GiB support is not yet present
<anarsoul> jernej: so I'll have only 3G in linux? :(
<anarsoul> oops I meant 2G
<MoeIcenowy> anarsoul: yes unfortunately
<anarsoul> darn
<anarsoul> any patches?
<MoeIcenowy> I have some ugly ones
huhligLI has joined #linux-sunxi
<anarsoul> I'm Ok with ugly patches for now
<anarsoul> what about USB and HDMI support in u-boot?
<anarsoul> oh, and ethernet
<anarsoul> :)
<jernej> I did some quick and dirty HDMI support
<anarsoul> (probably I'm asking too much)
<jernej> but I never found time to clean it up
<MoeIcenowy> jernej: btw I changed the reset sequence of the DRAM controlleron H6
<anarsoul> jernej: could you point me to a branch on your github?
<jernej> currently my focus is on ffmpeg request api support
<MoeIcenowy> and according to someone it fixes the wrongly detected size in SPL
<anarsoul> jernej: that's fine, I can clean up u-boot HDMI patches for you
<MoeIcenowy> anarsoul: https://github.com/Icenowy/u-boot/commits/h6-dram see commits at Feb 7
<anarsoul> MoeIcenowy: thanks
<MoeIcenowy> anarsoul: I did some rebase of h6 hdmi at https://github.com/Icenowy/u-boot/tree/h6-hdmi-rebased-1
<anarsoul> thanks again :)
<anarsoul> MoeIcenowy: anything for USB or Ethernet?
<MoeIcenowy> no
<anarsoul> :(
<anarsoul> that's unfortunate
<anarsoul> MoeIcenowy: what about linux? Does it support USB or Ethernet on H6?
<MoeIcenowy> anarsoul: all out of tree
<MoeIcenowy> I'm recently WIP on USB
<wens> usb was posted
<MoeIcenowy> for Ethernet unfortunately there's some problem now
<MoeIcenowy> Pine H64 model A will change Ethernet PHY power design
<MoeIcenowy> to match model B
<anarsoul> and I guess I have model A
<jernej> if it is the same size as Pine64, then it is model A
<anarsoul> yeah, it is
<MoeIcenowy> anarsoul: yes I think only jernej and I have model B now
huhligLI has quit [K-Lined]
<anarsoul> MoeIcenowy: OK, so any out-of-tree patches for ethernet?
AneoX_ has joined #linux-sunxi
<jernej> btw, why change design on model A, if it is already in production?
<MoeIcenowy> check my github
<MoeIcenowy> jernej: because there's more changes
<anarsoul> MoeIcenowy: what branch?
<jernej> that would mean incompatible DT for same model
<MoeIcenowy> mainly on the Pi-2 bus
<MoeIcenowy> jernej: and you should know Pine H64 is never sold now
<anarsoul> jernej: just use another compatible?
<anarsoul> oh
<MoeIcenowy> everyone gets only samples
<jernej> ah, ok :)
AneoX has quit [Ping timeout: 252 seconds]
<anarsoul> yeah, mine has signs of soldering (or rather flux) at the bottom
<MoeIcenowy> anarsoul: remembered my first sample
<jernej> well, H6 is pretty powerful chip, at least on graphics side
<MoeIcenowy> which uses a jumper wire for LPDDR3 1.2V
<MoeIcenowy> ;-)
<anarsoul> jernej: and it's 1.8 GHz :)
<anarsoul> I was going to use it to compile archlinux packages
<MoeIcenowy> anarsoul: as a conservative guy I choose to say it's 1.5GHz
<anarsoul> 1.2 -> 1.8 GHz boost would be useful for sure
<anarsoul> MoeIcenowy: well, A64 isn't 1.2 GHz either
<anarsoul> anyway, I put heatsink on CPU on my H64 board
<anarsoul> I did the same for Pine64-LTS and it never goes above 70C so it never throttles
<anarsoul> Pinebook throttles unfortunately, so e.g. youtube playback is not as smooth as on pine64-lts
<anarsoul> MoeIcenowy: so which branch should I use for ethernet support?
<MoeIcenowy> anarsoul: multiple branches contain it
<anarsoul> h6-integrate?
<anarsoul> I wonder how hard it would be to port ethernet support to u-boot...
<anarsoul> I need it for booting
<MoeIcenowy> not so hard
<MoeIcenowy> it's quite similar to A64
<MoeIcenowy> but you need to have a way to power up PHY
<anarsoul> ATF?
<MoeIcenowy> anarsoul: you can try
<MoeIcenowy> I wrote basic AXP805 code

<aalm> Svenska, looks pretty good to me, but i haven't read other device pages for ages, tho.
<Svenska> thanks for looking. :-)
Yonk__DQ has quit [Ping timeout: 246 seconds]
<Svenska> i don't know what else to add. i don't have uart access, anything else should be good enough
<aalm> do you have any pics of the pcb?
<aalm> (not for the device page, just curious myself)
<Svenska> no, but i can take one. doesn't look anything special to me, though.
<aalm> how much did it cost?
rtgiskard_ has quit [Killed (Sigyn (Spam is off topic on freenode.))]
<Svenska> let me check. nothing outlandish.
<Svenska> (i really prefer aliexpress over wish, but since the swedish post made that prohibitively expensive... idiots)
<aalm> i think i found it on ebay
<Svenska> 422 SEK
<aalm> hmpph, requires logging in to see anything
<aalm> i think i once had the app installed on my old phone, but don't think i made any account there
<aalm> was it that?
<Svenska> definitely not :-)
<Svenska> oh, wait, the second picture looks more like it
<aalm> fifth even more?
<Svenska> the ebay offer has "saintsmart" written on the back
<Svenska> also, my device has 4 GB of flash, advertised was 8/16
<aalm> i found some a33 tablet as "sainsonic" on amazon, but it was gone and no pics left
<aalm> with "QT-7"
<Svenska> hmm
<Svenska> hmm, it's hard to say whether it is the same device or not
<aalm> according to the link above, it appeared in 2015, which is likely given age of a33, so maybe some old stock of smaller models were dumped on wish for cheap
<aalm> w/o branding
<Svenska> but my pcb lists a 2017 date
<aalm> oh
<Svenska> and all timestamps are june 2018
<aalm> cool
<Svenska> still android 4.4 though :)
<aalm> well, i wan't to buy one of those, thnx:]
<Svenska> :-)
<Svenska> hmm. android mentions 7.8 GB available space, but a root shell only shows 2 GB
<Svenska> 2 GB free in /mnt/shell/emulated and 2 GB free in /data and 500 MB in /system
<aalm> btw., did the pcb look similar to this: http://linux-sunxi.org/A33_Q7_V1.0
<Svenska> no, unfortunately not (my board has 4 dram chips)

<Svenska> confirmed to only have 4 GB flash total - android has been patched to show 8 GB
<KotCzarny> ehehe
<KotCzarny> check other system data too
<KotCzarny> you might only have 512M of ram
<Svenska> there is 2.0 GB available in /sdcard and 0.5 GB in /system
<Svenska> no, ram is 1 GB according to meminfo
<KotCzarny> see 'patched' part :P
<Svenska> i checked /proc/meminfo...
<KotCzarny> see 'patched' part :P
dddddd has joined #linux-sunxi
<Svenska> nah
<Svenska> they didn't patch linux, they patched android
<Svenska> df also shows the true sizes
<KotCzarny> afair most a33 tablets come with 512M of ram
indy_ is now known as indy
<KotCzarny> inspect ram chips to be 100% sure
<Svenska> hmm
<Svenska> ...you won.
<Svenska> there are 4 memory chips 1 Gb each (512 MB total), and dd if=/dev/zero of=/dev/null count=16 bs=$((N*1024*1024)) fails for N>350 even after issuing "stop"
<KotCzarny> lol?
<Svenska> according to /proc/meminfo, there are 780 MB RAM free, but dd can't allocate more than 350 MB
<Svenska> and that is with dalvik stopped.
<KotCzarny> let me guess, android says 6.0 ?
<KotCzarny> ;)
<Svenska> no, 4.4.2
<KotCzarny> so at least that part is honest
<Svenska> there might be additional memory chips on the back side of the pcb
<Svenska> and it might be that some kernel parts fix-allocate some memory (think mali, cedrus etc)
<Svenska> so there might be some memory blocked off from userspace, or fragmentation or whatnot
<Svenska> i haven't tried this before on any other system though
<Svenska> okay, on a rockchip tablet i can actually use 800 MB blocks...
<Svenska> it lowmemkills the system_server, but hey... :-)
<Svenska> i am impressed.
<KotCzarny> cheap tablets are cheap
return0e has quit [Quit: Leaving]
<Svenska> no shit :-) the A33-Q8 i got on aliexpress did work as intended, though.
<KotCzarny> yeah, but they should come with honest specs
<Svenska> true, and working cameras might be useful as well (this device has two cameras, both take almost-black pictures)
<KotCzarny> you might get a nice refund if you can still open complaint
<Svenska> let's see...
<Svenska> never done that... first contact with wish
<KotCzarny> on aliexpress it's easy
<KotCzarny> and if you can present evidence it's 100% sure getting positive result
<KotCzarny> (otoh there are many counterfeit goods on ali..)
<Svenska> true, but i have bought there a few times and never felt cheated
<KotCzarny> i've had few dumb buys where seller was faking or just selling blindly
<KotCzarny> or when package got lost during delivery
<Svenska> problem is, sweden wants import tax and made a deal with PostNord which takes a fixed ~8€ fee for every package from china (independent of value!) - but they also made a deal with wish which avoids that fee
<KotCzarny> (i've heard whole containers get stolen)
<KotCzarny> anyway, nite!
<Svenska> so even some 50ct stickers get a 8€ fee on top of shipping and import tax, making aliexpress unattractive
<Svenska> apart from that, the stock firmware is /really/ bad (i.e. the quickbar only has "brightness" and "autorotate", no wifi or such)
