04:58.52ManoftheSeaIs this the right place to get help with making rootfs on SDcard for working with a10 devices?  Or is there a seperate channel for that purpose? mnemoc?
05:25.36TurlManoftheSea: yeah
05:25.45TurlManoftheSea: you won't be able to run the kernel on qemu though
05:26.09TurlManoftheSea: I suggest you use a chroot + binfmt with qemu-static-arm
05:28.36ManoftheSeathanks turl.  I will attempt to figure out what you said, but it looks useful.

05:35.21ManoftheSeahas found info on the internet. Will have more questions tomorrow
05:42.55ManoftheSeaok, I think I got debootstrap --second-stage running in a qemu chroot.
05:43.20ManoftheSeaTomorrow, I find out if my uboot and kernel match correctly.  MK802 mk. II here.
05:47.31TurlManoftheSea: I was suggesting debootstrap with --foreign, then installing qemu-user-static on your pc (sets up binfmt by itself even), then copy /usr/bin/qemu-arm-static yourchroot/usr/bin
05:47.49Turlthen chroot to the arm install and run the second step (debootstrap --second-stage or so)
05:48.23ManoftheSeaYep.  Thanks, turl, I found all that just from your mention of the programs.  I have completed the second stage, and an finalizing the debootstrap now.
05:49.07TurlI think there's even a guide of it on the wiki
05:49.38Turlhttp://linux-sunxi.org/Debian :)
05:50.16ManoftheSeahmm, I didn't find that yet.

11:31.58hnoTurl, MALI apparently have a static region it's allowed to DMA to, other regions apparently gets copied by the CPU.. Saw some post in developer.arm.com forum about performance issues and ARM pointed to possible kernel/userspace mismatch in allowed direct access memory region.

14:33.23TurlQuarx: :)
14:33.47Turlneeds to push his 4.2 work to github
14:33.53Quarxoo
14:33.59Quarxwhat works?
14:36.10TurlQuarx: it boots, wifi works, audio works
14:36.23TurlQuarx: need to test hwcomposer, it wasn't loading due to bad version
14:36.40TurlQuarx: we are affected by the same mali issues as the exynos people
14:37.27Turlmaybe need to adjust mountpoints, haven't checked what's the new ones on 4.2
14:38.33RaYmAnmountspoints need fixing, otherwise android crashes
14:39.03Quarxon razr we didn't change anything
14:39.08Quarxafter 4.1
14:39.23Quarxbut on defy i still can't get work sd-ext
14:39.59RaYmAnyou didn't add that silly patch that just hacks around having to change mountpoints?
14:40.16TurlRaYmAn: well it didn't crash for me o.O
14:40.32RaYmAna lot of people decided to fix the symptom rather than fix the cause
14:40.37Turlunless CM merged that patch
14:40.45RaYmAnthey might have I guess
14:41.00TurlRaYmAn: what's the new mountpoints btw?
14:41.16Turlwe have internal+external vfats
14:41.30Quarxon defy i can browse sdcard only via adb, android didn't see files and sd%)
14:41.33Quarxbut it's mounted
14:43.55RaYmAnTurl: well, not mount points per say I guess, but the mount stuff in init.<device>.rc: http://pastebin.com/0gkkvSnA
14:44.48TurlRaYmAn: well I've been using /storage/sdcardX since 4.1
14:44.58TurlI didn't add any of the other emulated crap though
14:45.37Turlwhere do you mount stuff with vold?
14:46.17RaYmAnTurl: of course, that was required in 4.1. This is required in 4.2
14:46.38Turl/storage/sdcard0 is a symlink, where do you mount it then? :p
14:47.50RaYmAnI mount internal eMMC data on /data as always
14:48.06Turlyeah but that's not internal vfat
14:48.08Turl:)
14:48.23RaYmAnyeah, there's not really any place for internal vfat anymore :P
14:48.45QuarxRaYmAn: any changes for sd-ext?
14:49.07Quarxdefy doesn't have internal vfat
14:50.45jinzoMotorola Defy is using an A10?
14:51.08Turlno, it has an OMAP3 CPU
14:51.18RaYmAnthis channel might have become mostly a10, but it is still a generic channel ;)
14:51.27jinzoah ok, sorry - I loked at your android github repo and had to ask
14:51.55jinzoRaYmAn, I actually tought because of "Repo entries for CM7/9/10 Nightly builds, Motorola Defy,Defy+,Bravo. Ainol Novo7 Aurora(A10) "
14:52.05Turlcpu wise it should be roughly equivalent on performance
14:52.17Turlboth are cortex a8 and the clocks are fairly similar
14:52.58jinzobut it's very nice to see someone is working on a A10 CM (and I quite like ainol as a company)

14:57.23Quarxi wonder why they no release official 4.1
14:57.25jinzo(and they're quite interesting, every new product "line" they out has a new processor - and everything in there has the same on - A10 for previous, AML8726-M6 for current ad ATM7029)
14:58.03jinzoprobably because they wish to make money off the new ones - they're pumping new products at high pace and like I said - newer the same platform
14:58.38jinzoI really don't know why underdogs like them don't go with CM all the way
14:59.03Quarxbut almost all sources available for 4.1 (from allwinner)

15:31.24hipboiA31 first
15:31.25hipboiA20 later
15:31.25hipboijust like A10 and then A13
15:31.52Turlso allwinner doesn't have A20 chips yet?
15:32.12hipboisorry, i don't know
15:32.26hipboii only know the time order
15:33.28TurlA20 is pin compatible with A10 and has Mali GPU
15:33.35hipboiyes
15:34.01Turlpersonally I think it would be a better fit (lima hint hint :) ) and faster to make for you guys
15:34.16Turland I think it has sata so you don't need to lose features

15:35.52ManoftheSeaGood morning guys
15:36.43GumbootYay gigabit!
15:36.43ManoftheSeaI'm messing with a MK802 mkII, and I think I got my root fs all set up and qemu-debootstrapped.  I see some reference to "issue 46", but the page doesn't load.
15:37.05ManoftheSeaWhen I try to boot, no output.
15:38.23Turldid you flash uboot to your card and set up kernel properly?
15:38.51Turlalso, what output are you expecting?
15:38.52ManoftheSeaI have an 8 GB SDcard, with SPL at 8k and uBoot at 32k, then a 32MB partition formatted vfat with uImage and script.bin, then a root partition.
15:39.27ManoftheSeaTurl: I have the MK802v2 hooked up to HDMI.  I thought I'd get a console.  no?

15:39.48TurlManoftheSea: did you enable fbcon? your best bet is to use uart though
15:40.01Turlthere's a lot of stuff that could go wrong
15:40.05Turland you cannot catch it with hdmi
15:40.12Turlyou probably need an uboot environment/uEnv.txt to add rootwait btw
15:42.57ManoftheSeahmm...  I like your suggestions, but I have no idea what you're actually saying.  uart requires taking the case off the stick and connecting to JTAG?

15:44.23Turlthere's a pic pointing at the uart pins there
15:45.45ManoftheSeaso, not serial.
15:47.24ManoftheSeayeah, that's not the same one.  I have a mk2, which has 2 micro-usb
15:47.34ManoftheSea(and a full size USB)
16:12.51ManoftheSeaok, I don't have a boot.cmd.

16:57.38ManoftheSeaso, "first-steps" doesn't say what to do with boot.scr.  Does it go on the boot partition?
16:58.00Turlyes, together with script.bin and uImage
16:58.33ManoftheSeaand you mentioned using fbcon.  That goes in /etc/modules?
16:59.16Turlpossibly, don't know for sure
16:59.46Turlprefers =y instead of =m if he is going to use the feature, =n otherwise
17:00.05ManoftheSeaok, I'll check the .config
17:00.12ManoftheSeaI don't have the module, it seems
17:02.27ManoftheSeasays no.  Guess I need a toolchain and a recompile.  Whee!  Thanks again, Turl

19:08.04hnoManoftheSea, for small changes to the boot procedure uEnv.txt is simpler.
19:22.23techn_hno: finally I found trigger for that boot problem :/
19:23.31techn_If I comment out sunxi_gpio_set_cfgpin(SUNXI_GPB(22), SUN4I_GPB22_UART0_TX); \ sunxi_gpio_set_cfgpin(SUNXI_GPB(23), SUN4I_GPB23_UART0_RX); , device boots
19:24.19techn_I'm wondering why it's so.. and why lichee u-boot  doesn't have those lines :/
19:30.39ManoftheSeahno, it looks like I shouldn't be expecting HDMI out, right?  So, I need to get the usb->uart before I can do more.
