<stoupaxyz> LIST
<stoupaxyz> Hi all, I'm working on A10s-OLinuXino-Micro board iwth 4GB NAND. The MMC boot is working nicely, but I'm not able boot Linux from u-boot (sunxi branch) as I'm unable to load kernel from NAND. Is NAND boot from u-boot possible with current sunxi branch? I must admit that I'm lost in the status of flash support...
<oliv3r> stoupaxyz: tha sounds about right, you can't boot from nand currently
<stoupaxyz> ok, thanks - and with lichee-dev branch? I tried it but there is no borad support
<stoupaxyz> *board
<oliv3r> you can't
<oliv3r> there's the boot0->boot1->boot.axf->u-boot chain, for which there is nand support
<oliv3r> but other then that, no nand support
<oliv3r> the kernel supports nand just fine
<stoupaxyz> ok, I was afraid of that...
<stoupaxyz> And do you know how cubieboard is booted? Cubian supports NAND boot. Linux is started diretcly from boot.axf?
<stoupaxyz> w/o u-boot?
<oliv3r> nope, it's chainloaded via lichee-u-boot
<oliv3r> e.g. via boot0
<oliv3r> our u-boot only does mmc/tftp, no nand
<oliv3r> if you want nand boot, you need boot0/boot1/boot.axf/u-boot chain that's pre-installed
<oliv3r> (you could recompile it from the lichee branch, but no point on doing so really
<stoupaxyz> ok, understand. Thanks for information! Bye.
<oliv3r> noprob, bye :)

<tomboy64> gis there a way i can get access to uEnv.txt on nanda on my cubietruck without actually flashing something?
<tomboy64> e.g. via usb otg?
<Turl> tomboy64: you can boot any system using an sd card and then access it
<tomboy64> Turl: my problem is, i am trying to boot an sd card but just get a blinking cursor, nothing else happening.
<tomboy64> Turl: a few days ago i put root=/dev/mmcblkp2 in my nanda's uEnv.txt - and when i try to boot the nanda it locks in a cycle of rebootage
<tomboy64> so i think it's that thing trying to boot from the wrong partition here
<libv> tomboy64: blinking cursor is good
<libv> means that disp and lcd are loaded
<libv> tomboy64: try making tty0 your console
<tomboy64> hehehe

<hno> [7] have avoided Allwinner NAND driver in u-boot because there is just too many versions, and using the wrong version results in the NAND being automatically reformatted.
<hno> plus it's not the path we want to go.
<oliv3r> hno: i will be working a little bit to improve BROM
<oliv3r> hno: i know it's not utterly usefull, but it's still a 'nice to have' i'd think
<hno> Yes, better understanding of BROM migh be useful, and if nothing else it's good learning to try to read ARM assembly.
JohnDoe_71Rus has quit [Quit: KVIrc 4.0.4 Insomnia http://www.kvirc.net/]
<hno> but seriously, there isn't much more to learn from BROM. It's function is very limited.
<oliv3r> i know, but I don't know asm; so i'm getting that from that
<oliv3r> and i was gonna see what is needed for SPI-NOR to boot; i saw you've added some comments
<oliv3r> also, i think it'll be cool if we have it all documented at least
<[7]> are there even devices with spi-nor?
<oliv3r> so yeah besides the 'cool' factor, nothing much
<hno> Hm.. one thing might be interesting. Which ECC modes do the NAND loader support? I think there is at least three modes.
<oliv3r> spi-nor with u-boot, sata with OS is what i'm aiming at
<oliv3r> hno: and you thinka ll 3 are in brom?
<hno> oliv3r, I am talking about the NAND loader in BROM yes.
<oliv3r> since that's probably the biggest chunk, i may very well do that last; but yeah i could in theory still be helpfull
<hno> the SPI-NOR part is trivial, haven't felt there is any need to even try reversing it.
<oliv3r> when i started it, i didn't realize you allready commented the key parts :)
<hno> getting OS on SATA means adding SATA support to u-boot, which in itself is an interesting project.
<oliv3r> anyway, it's a cool arm-asm learning project
<hno> indeed.
<oliv3r> well platform ahci for mainline is almost done
<oliv3r> it works (tm) now
<hno> good
<oliv3r> so just gotta sort some things, maybe toss a few things around
<oliv3r> but it's quite minimal
<oliv3r> so once that's accepted upstream or close to; i'll add it to u-boot aswel
<hno> excellent
<oliv3r> so i'm excited for that
<hno> looking forward to that, a lot.
<oliv3r> with a 256k SPI chip, we could boot from sata without nand
<oliv3r> btw, how's your bitcoin business going?
<oliv3r> the last month most have been crazy with the current conversion rate
<oliv3r> i'm even thinking of trying to mine 1 or 2 coins myself, but no clue how long it would take my x64 CPU (dunno if i can do GPU in linux)
<hno> Yes. You only need the SPL in SPI flash so 256k is plenty.
<hno> it's not my business, only one of the "slaves" in it. But it's doing quite well. Every time orders are opened it sells out in some hours.
<oliv3r> with bitcoin prices going up to 1k it's very interesting
<oliv3r> but looks like i need about 100 days of full GPU usage for 1 bitcoin
<hno> Trying to mine bitcoins with a CPU is quite meaningless today, and haven't been supported by the main mining applications for a long time. Even GPU mining is pretty much meaningless (and thus removed from the mining software already) and it's several orders of magnitude faster than CPU mining.
<oliv3r> yeah i'm reading as you type that
<oliv3r> you need an asic really; not even an FPGA
<oliv3r> asic is quite better then an FPGA
<oliv3r> i guess the butterflylabs.com bitcoin mining card would have been awesome :)
<oliv3r> oh well
<hno> th BFL ones are obsolete too..
<oliv3r> what does your company produce?
<hno> an bitcoin mining ASIC, and full miners built around it. kncminer.

<oliv3r> ah cool
zeRez has joined #linux-sunxi
<oliv3r> how much they going for?
<hno> oliv3r, prices are listed in the shop, but all sold out at the moment.
<hno> second-hand prices on ebay are way off the scale.
<hno> crazy world.
<oliv3r> yeah
<oliv3r> with prices going from ~200 -> 990 USD in 6 weeks everybody wants in
<libv> aren't those asics obsolete the second you get them?
<oliv3r> well if you can get 2-4 bitcoins at the new rate (and that may be even go up) it may be profitable (like as some vacation money)
<libv> price of the device + power to drive them < what you can earn
<oliv3r> i know some people try to get horrible rich
<oliv3r> libv: well the thing is, the last 6 weeks, prices went up 8x
<oliv3r> it spiked at 1000 USD per bitcoin
<libv> that's speculation
<libv> purely
<oliv3r> all the old GPU + power stories where at 200 USD per coin
<oliv3r> i'm just bummed out i didn't mine a bit when it all started
<oliv3r> :p
<libv> imho not worth the hassle

<oliv3r> if i had 5-10 bitcoins then, or bought them when they where in the 20's of dollars a pop; i'd gottan a nice amount of money for them now ;)
<oliv3r> oh well; all after the fact
<libv> oliv3r: that's what everyone thinks _today_
<libv> might be quite different tomorrow

<libv> like with everything that is being speculated on
<libv> if only you had bought it when it was cheap, many many months ago

<oliv3r> bummed out is all :p
<oliv3r> the cash would have been awesome
<oliv3r> even just a few hundred bux
<libv> oliv3r: there's always some goldrush going on somewhere.
<hno> hehe,, there is worse things you can do with bitcoin speculation..

<oliv3r> oh interesting
<oliv3r> hah! a friend of mine bought half a bitcoin a few years ago; but he forgot his password
eebrah_ has joined #linux-sunxi
<oliv3r> while it's only 'half' it's still 400 USD or so
<oliv3r> i wonder what happens with all those 'lost' bitcoins
<libv> oliv3r: stop caring, now :)

<oliv3r> just being distracted
<libv> :)
<oliv3r> actually; rough week; so i'm relaxing atm really
<oliv3r> though I did play with sunxi ahci today and it does seem to work now!
<libv> worrying about having missed a goldrush is not going to help you relax :)
<hno> oliv3r, a lost bitcoin is.. lost.
<oliv3r> just need to talk to mripard_ on what the proper way is (i didn't quite understand it frmo his e-mails) and probably get involved with linux-ata
<oliv3r> hno: so what if, in time, everybody looses their bitcoins. with real money, you re-print it; with bitcoins, the value soars?
eebrah has quit [Ping timeout: 272 seconds]
<oliv3r> until thers none left?
<hno> bitcoins can be divided in very very small pieces.
<hno> 10^-8

<focus2> Allwinner 64 bit CPUs - how many ethernet? They should put on at least to gbit or the device will under perform in server applications
<focus2> (two gigabit ethernet ports i meant)
eebrah has joined #linux-sunxi
<libv> focus2: where?
<oliv3r> focus2: doesn't exist yet :p
<oliv3r> might be a90
<focus2> libv: hopeful that some allwinner engineers listening :)
<libv> focus2: allwinner is which end of the market?
<libv> only wondermedia (via) and telechips are lower
<oliv3r> arm 64 bit will be all over in 2 years, even low end
<libv> 2years is a very long time in the current environment
shineworld has joined #linux-sunxi
<focus2> libv: the 64 bit will outshine a 1gbit ethernet - even with a page turn limit of 10MHz and 8 bytes to a 64bit word, that gives you 80M bytes per second = 1 gbit of data in worst case, but usually if handled by DMA, page change is less frequent and easily get throughputs of 100's of megabytes per second. Easily need 2 x gbit ethernet to handle it.
<libv> ...
<focus2> For server applications all that the outside world sees is through the gbit interface - so they should put at least 2 gbit ethernet to keep the 64 bit CPU busy :)
<Turl> oliv3r: I believe they're supported (ahb gate and a mod0) but you're welcome to verify and try them :)
<oliv3r> wingrime: ^
<Turl> oliv3r: wingrime wanted it merged upstream though :p

<libv> "age"?
<libv> [7]: you mean like, 6 months ago?
<oliv3r> mripard_: so rewriting or adding to ahci_platform.c is needed then? well i guess i wasn't wrong when I said we need an ahci_platform_register() :p
<libv> or was that already a year
<[7]> kinda
eebrah has joined #linux-sunxi
<mripard_> oliv3r: yeah, probably :)
<mripard_> but you never explained what ahci_platform_register was supposed to be :)
<libv> [7]: this whole bitcoin mining thing does rather smell like a ratrace :)
