<plaes> which u-boot did you use for H3 (Orange Pi PC?)
leviathanch has quit [Read error: Connection reset by peer]
<wens> plaes: jemk has a branch for h3 support iirc
<plaes> yup, saw that
<atx> I do not think that one works on Orange Pi PC
<atx> At least for me, it failed in DRAM initialization
<atx> Someone posted a fix on the mailing list iirc

pmattern has joined #linux-sunxi
<wens> yeah, had something to do with zq calibration
<lemonzest> Banana Pi M3 is available to buy now :), A83T i think
<lemonzest> £52/74euro, dunno dollars
domidumont has quit [Ping timeout: 246 seconds]
<wens> it says pre-order on taobao, 442 RMB
<lemonzest> i ordered mine from aliexpress
<lemonzest> hard release was today
<wens> the bpi m3 uses lpddr3 instead of normal ddr3 dram
<lemonzest> lp = low power?
<plaes> oh cool, hans just pulled jemk's stuff into his repo :)

<plaes> doesn anyone have an idea what this mgray in the dram calibration means?
<jemk> plaes: modified gray code (gray code, but bit 0 normal binary)
<plaes> ok.. this number sequence is weird :)

[7] has joined #linux-sunxi
<plaes> weird, because this isn't documented in mathematics world :P
<plaes> I managed to find similar sequences though: http://fpaste.org/290812/14476078/raw/
<plaes> math seems to check out and it still boots
<montjoie> oh my god it is the first time I open the SDK, they have zipped allk .o files in kernel tree:)
<jemk> plaes: i don't know the reason for this code, one would propably need to know more about the hardware implementation to understand that
<plaes> this is what I got with the new tables: http://fpaste.org/290814/14476086/raw/
<jemk> the code is correct, no problems there. and as long as you dont use para->zq_correction its not even relevant
<jemk> ok, in the version i posted it is used...
<plaes> I pulled the code from your github

<TheLinuxBug> lemonzest> Banana Pi M3 is available to buy now :), A83T i think -- link?
<TheLinuxBug> holy shit
<TheLinuxBug> 20$ shipping to US
<TheLinuxBug> :(
<TheLinuxBug> I assume the m3 is using another SATA -> USB adapater?
<NiteHawk> TheLinuxBug: yup. the A83T doesn't offer native SATA afaik

<ssvb> wens: maybe ddr3l instead of lpddr3?
vishnup has quit [Remote host closed the connection]
<ssvb> plaes: ok, I guess you have already found a usable U-Boot for H3 by now
<ssvb> plaes: jemk also has a h3 kernel branch if you want to try it
iamfrankenstein has joined #linux-sunxi
<plaes> ssvb: yup, got it working
<plaes> ssvb: in case you have time, could you also check this: http://fpaste.org/290847/raw/
<ssvb> plaes: well, first we need a memory testing tool to get some sort of a feedback about our potential changes in this code
<plaes> ok
<ssvb> moreover, even if your change happens to make the reliability worse, different ZQ value in the config file could potentially address this :)
<ssvb> and we even still don't know if the current ZQ value is actually optimal for Orange Pi boards even with the current DRAM code
<plaes> I really don't know anything about this :S
<plaes> I just wanted to figure out how this table was generated

<NiteHawk> ssvb: did you ever notice the FEL transfer speed on the A20 to be considerably lower when no uart is attached?
<ssvb> NiteHawk: no, maybe I need to check this on my hardware
TaD_ has joined #linux-sunxi
<NiteHawk> came across that when testing the progress bar stuff - http://irclog.whitequark.org/linux-sunxi/2015-11-13#14603027
TaD_ is now known as tdack
<NiteHawk> my bpi consistently show ~560kB/s, even with UART attached but minicom inactive, and ~950kB/s when "connected"
<NiteHawk> surprised me a bit, since i didn't expect those transfers to be related to the serial port in any way...
<ssvb> hmm, this is rather strange
<NiteHawk> thought so :D if you find some time, maybe you could occasionally try to reproduce that

<PhilippeBaret> when using livesuit
<PhilippeBaret> trying to solve PANIC messages
<PhilippeBaret> you need to run modprobe -r awusb.ko
<PhilippeBaret> i have this output modprobe: FATAL: Module awusb.ko not found.
<PhilippeBaret> i am running command inside the awsub file where there is such a file though
<PhilippeBaret> any idea ?
ricardocrudo has quit [Remote host closed the connection]
<PhilippeBaret> modprobe -r awusb was the trick, with no ".ko"
mstar_ has joined #linux-sunxi
<TheLinuxBug> The module you are trying to insert is not made for the kernel you are using
<TheLinuxBug> ah
<TheLinuxBug> didn't see your thing about modprobe
<TheLinuxBug> glad you figured it out
