| 10:04.24 | RaYmAn | mnemoc: are there any reasons for not merging sun3i, sun4i and sun5i? I mean, other than the devices available, they seem pretty identical? - the minor differences could easily be #ifdef'ed |
| 10:08.29 | *** join/#arm-netbook ZaEarl (~malmrose@203-97-164-178.cable.paradise.net.nz) |
| 10:08.33 | mnemoc | RaYmAn: their reason is that they provide only partial sources to each manufacturer |
| 10:09.03 | RaYmAn | mnemoc: I more meant as far as we are concerned :) |
| 10:09.20 | RaYmAn | e.g. => 3.4 branch |
| 10:09.20 | mnemoc | RaYmAn: our goal is to merge them, first step is plat-sunxi, but human resources are VERY limited |
| 10:09.53 | RaYmAn | yeah, I'm aware |
| 10:10.09 | RaYmAn | I'm obviously asking these questions because I do want to try and find time to pitch in =P |
| 10:10.12 | mnemoc | in 3.4 I'm trying to clean the script handling, then gpio, plat-wide |
| 10:10.47 | mnemoc | RaYmAn: many drivers also need to be unified, specially the disp beast |
| 10:11.20 | RaYmAn | ok, I might take a stab at comparing mach-sun5i to mach-sun4i and merging sun5i specific stuff (with suitable #ifdefs).. Even if it's -> mach-sun4i, it's still a step in the right direction |
| 10:11.24 | RaYmAn | yeah |
| 10:12.14 | mnemoc | sun4i and sun5i are easier to merge than sun3i, which was abandoned by allwinner before 2.6.36 (our older code available) |
| 10:12.21 | RaYmAn | yeah :/ |
| 10:12.41 | mnemoc | but looking carefully sun3i is also very similar to it's bigger brothers |
| 10:13.46 | mnemoc | RaYmAn: the greatest help at the moment would be a new sunxi kms driver |
| 10:14.22 | mnemoc | libv suggested using omapdrm as template^Winspiration |
| 10:14.53 | RaYmAn | yeah - I suspect I'm nowhere near familiar enough with sunxi to do that |
| 10:14.54 | RaYmAn | :P |
| 10:15.11 | mnemoc | RaYmAn: no one is :) |
| 10:15.43 | RaYmAn | I suppose :P |
| 10:15.44 | mnemoc | a less agressive step would be to flatten the sun[45]i drivers |
| 10:16.04 | mnemoc | because they currently use layer after layer of some OS-agnotisc fybar |
| 10:16.06 | mnemoc | fubar |
| 10:16.23 | mnemoc | which we need to peel off |
| 10:16.24 | RaYmAn | sounds like tegra in 2.6.32 variant :P |
| 10:17.09 | mnemoc | if you can remove the layers and wrapper it will be much simpler to add fbcon support |
| 10:17.16 | mnemoc | and to merge sun4i and sun5i video dirvers |
| 10:17.36 | mnemoc | and there is no special knowledge needed for that |
| 10:17.52 | mnemoc | at the end, you'll know enough to implement the sunxi kms driver :) |
| 10:18.31 | mnemoc | deal? :) |
| 10:19.01 | RaYmAn | lol |
| 10:19.06 | RaYmAn | sure, i'll be done in around 3 years |
| 10:19.07 | RaYmAn | :P |
| 10:19.28 | mnemoc | sooner someone begins, sooner we'll get it done :) |
| 10:20.27 | RaYmAn | yeah - I guess I should start with actually making current source work on my a13 devices |
| 10:21.03 | mnemoc | we have a sun5i branch awaiting for such work |
| 10:21.49 | mnemoc | it un-removes sun[34]i, and un-removes the code Tsvetan got binary-only |
| 10:22.26 | mnemoc | also turned random chinese encodings into utf8, and `dos2unix` |
| 10:22.31 | RaYmAn | lol |
| 10:23.08 | mnemoc | it's 3.0.8, but much cleaner and complete that the mess on their SDK |
| 10:23.22 | mnemoc | but needs to be merged into our main branch |

| 10:26.31 | mnemoc | once we get lichee3-sunxi working, forwarding the new sun5i stuff will be trivial |

| 10:30.54 | mnemoc | oh, nice |
| 10:32.39 | mnemoc | we really need to merge wip/lichee3-sunxi/import-sun5i :) |
| 10:33.16 | RaYmAn | I guess |
| 10:33.32 | mnemoc | all yours :) |
| 10:35.54 | RaYmAn | I'm just wondering if it makes more sense to figure out differences, then just adapt sun4i to work? |
| 10:36.40 | mnemoc | i'm more fond to "Baby steps" (easier to debug breakages), but it's up to you |
| 10:40.19 | mnemoc | the reason to keep the lichee3 branch alive is because it mostly remains compatible with the close tree, and so people can use it build modules without replacing the whole world |
| 10:40.35 | mnemoc | but I'm probably over-caring about that use case |
| 10:43.25 | RaYmAn | ah, I guess that sorta makes sense |
| 10:43.38 | RaYmAn | but I'm not sure it warrants further development in that branch =P |
| 10:44.05 | mnemoc | been a different mach- it can be shared |
| 10:44.31 | RaYmAn | it just seems a bit silly to have to maintain two branches that are mostly identical |
| 10:44.33 | mnemoc | also as that's our starting point for sun4i support, it's easier to diff with whatever allwinner releases |
| 10:45.12 | mnemoc | no development goes there, only importing releases/leaks to then forward port |
| 10:46.56 | mnemoc | but as I said, I don't have an strong defense for it, and if it's an obstacle to get help, f* lichee3 |
| 10:47.25 | RaYmAn | My issue is probably not having a clue how different sun4i and sun5i is |
| 10:47.42 | mnemoc | at lichee3 level you can diff straight away |
| 10:48.02 | mnemoc | in the main branch it's harder because sun4i has been improved |
| 10:48.10 | mnemoc | at 3.4 level, it's even harder |
| 10:48.53 | mnemoc | because of api changes, etc |
| 10:49.01 | mnemoc | and plat-sunxi work |
| 10:49.20 | mnemoc | that's why I find value on the lichee3-sunxi branch |
| 10:50.00 | mnemoc | while the official 2.6.36 helps us find the diffs between sun3i and sun4i |
| 10:50.08 | mnemoc | lichee3 does the same for sun4i vs sun5i |

| 16:47.09 | lukestuts | But then hangs. |
| 16:47.18 | rm | I am fighting here with an MK802 that doesn't boot from an SD card... |
| 16:47.25 | lukestuts | At first, I thought it was a 512MB vs 1G ram thing |
| 16:47.32 | lukestuts | But now I am not so sure |
| 16:47.43 | lukestuts | Ah, that sounds like a similar thing |
| 16:47.54 | lukestuts | We have a Large Number of A2000s here |
| 16:47.56 | DonkeyHotei | they all have 512MB |
| 16:47.59 | rm | I have 2 MK802, 512MB and (supposedly)1024MB |
| 16:48.06 | lukestuts | Approximately 1/3 of them have this problem |

| 16:48.08 | rz2k | post boot0/1 output |
| 16:48.33 | rm | rz2k, maybe I am too stupid or LiveSuit is too chinese for me |
| 16:48.37 | lukestuts | Is boot0/1 output the output from UART? |
| 16:48.46 | rz2k | yes |

| 16:49.19 | lukestuts | ok, shall I put it on pastebin or similar? |
| 16:50.12 | rz2k | lukestuts: then, if it goes to u-boot you will see whats happening there, it should execute initial stuff like loading script.bin to exact address and etc. if this stuff fails u-boot will tell you |
| 16:50.21 | rz2k | paste that to pastebin |

| 16:53.25 | lukestuts | This is the boot output when booting from nand (using A10's ICS): http://pastebin.com/Sgmm0u9V |
| 16:54.21 | rz2k | rm: common tactic with livesuit: select firmware, press flash without anything attached, you will see obvious message about that nothing is attached, now press FEL button and attach device |

| 16:55.03 | rz2k | dont close error message, wait 5-8 minutes |
| 16:55.33 | rz2k | flashing will go background |
| 16:55.47 | lukestuts | rz2k: Is there a way to use LiveSuite with the A2000? |
| 16:56.04 | rz2k | lukestuts: now paste whats happening if you boot from SD |
| 16:56.31 | rz2k | lukestuts: yes, all sunxi devices use livesuit/phoenix protocol called eFex to flash internal nand |
| 16:56.36 | lukestuts | Will do, just reimaging my card to make sure it's the right image! |
| 16:56.57 | lukestuts | So I just have to have the A2000 on the same LAN? |
| 16:57.24 | lukestuts | Got to say, these are great things |
| 16:58.15 | rm | it's not LAN based, you need to connect it to a (Windows) PC via USB |
| 16:58.55 | lukestuts | Ah, so I need to make a USB connector for the internal USB inside the A2000? |
| 16:59.11 | rm | I think one of the external ones will work |
| 16:59.19 | lukestuts | USB A-A? |
| 17:00.08 | rz2k | pokes mnemoc |
| 17:00.46 | rz2k | I dont have mele so I cant say anything about what port you need to use to connect it to livesuit |

| 17:05.13 | rz2k | in mailing list, there was a guy who had mele with bad DDR3 |
| 17:05.31 | lukestuts | Is there an archive that I can read? |
| 17:05.32 | rz2k | he excluded 16MB from being used and that fixed it |
| 17:05.58 | lukestuts | Aha found gmane |
| 17:06.38 | rz2k | also, if you have a mele that you can kill for the fun, do a reball/reflow of DDRs |
| 17:08.01 | rz2k | my ly-f1 tablet had "init SDRAM fail" from boot0 or really unstable android, reflow helped for some time. |

| 17:22.51 | lukestuts | I'm also running up this freezing board that I pastebinned earlier and it's now sending Different backtraces while loading the kernel |
| 17:23.09 | lukestuts | Which suggests bad ram imho |
| 17:23.17 | rz2k | (apart from getting 50/50 init DRAM fail from boot0 on start) |
| 17:23.42 | lukestuts | rz2k: this is pretty much exactly what i have :( |
| 17:23.51 | DonkeyHotei | the guy on the mailing list with bad ram had the A1000 iirc |
| 17:24.07 | mnemoc | dram init args are hardcoded in boot0, it may fail with different chips |
| 17:24.08 | lukestuts | when you say reflow with a soldering station, you mean an infra-red heatlamp thing? |
| 17:24.27 | rz2k | no, cheap air chinese crap |
| 17:24.52 | rz2k | I got it for $40 bucks few years ago, still it didnt die or something |
| 17:25.12 | mnemoc | it would be nice to check if there is correlation between between init failure and dram IC models |

| 17:27.50 | rz2k | lukestuts: you can reball/reflow small BGAs with air, big ones like northbridges or CPUs will need infra-red and preheaters beneath the board |
| 17:28.15 | rz2k | (infrared station is $1k + minimum) |

| 20:31.57 | mnemoc | rm: if you can to force a cmdline (including your root=) use CONFIG_CMDLINE and CONFIG_CMDLINE_FORCE |
| 20:32.16 | rm | bus error again |
| 20:32.43 | diego_ | rm: |
| 20:32.58 | diego_ | rm: try this-> ulimit -c unlimited |
| 20:33.03 | diego_ | rm: run again |
| 20:33.08 | diego_ | rm: file core |
| 20:36.04 | rm | looks like the bus error is not because of the change |
| 20:38.03 | diego_ | I suspect a bug in the compiler |
| 20:38.19 | diego_ | if it is the compiler that gave you the bus error |
| 20:42.25 | rm | I had time/date set incorrectly |
| 20:42.35 | rm | let's see if that was the problem |
| 20:48.14 | rm | yes, after fixing the time and make clean it seems to build |
| 20:48.41 | rm | and I switched to CONFIG_CMDLINE anyway, just did not know there was CONFIG_CMDLINE_FORCE |
| 20:49.07 | rm | mnemoc, is "mem=" needed on 2.6.38? |
| 20:53.23 | mnemoc | 2.6.38? |
| 20:54.02 | rm | ewwwr |
| 20:54.11 | rm | 3.0.38 |
| 20:54.52 | mnemoc | unless you have something defective you shouldn't need mem= at all |
| 20:56.25 | mnemoc | what mem= your stock image passes? |
| 20:57.19 | rm | CONFIG_CMDLINE="mem=448M@0x40000000 console=ttyS0,115200" |
| 20:57.27 | rm | this is from https://github.com/amery/linux-allwinner/blob/allwinner-v3.0-android-v2/arch/arm/configs/sun4i_defconfig |
| 20:57.32 | rm | my stock image does not pass mem= |
| 20:59.58 | mnemoc | you can ignore that one |
| 21:00.46 | mnemoc | it's just the normal 512-64 |
| 21:03.07 | Turl||webchat | rm: can't you just use root= on cmdline? |
| 21:05.07 | rm | I considered it would be nontrivial to change the command line that the NAND bootloader passes |
| 21:05.45 | rm | seems easier to hardcode it in the kernel |
| 21:06.00 | Turl||webchat | the 'nand bootloader' is uboot usually |
| 21:06.19 | mnemoc | rm: be sure to force it, or root= from bootloader will win anyway |
| 21:06.20 | rm | right |
| 21:06.58 | rm | CONFIG_CMDLINE_FROM_BOOTLOADER=n , CONFIG_CMDLINE_FORCE=y |
| 21:07.14 | mnemoc | :) |
| 21:07.28 | Turl||webchat | rm: or if you want to use the ultimate hack, https://github.com/Atrix-Dev-Team/kernel-MB860/commit/0e2a7def19e5fc6d3f0f3aa3e17ed0c0fd67585a |
| 21:10.04 | rm | yay someone's SoC is even messier than 'ours' |
| 21:10.13 | mnemoc | :) |
| 21:14.27 | Turl||webchat | I hope you never get to see nvidia .32 kernel :D |
| 21:15.06 | Turl||webchat | It'll make you want to vomit, RaYmAn here can testify too :P |
| 21:38.16 | hno | rm, it is almost trivial to change the nand bootloader command line using serial or fw_setenv. |
| 21:39.00 | hno | if using u-boot. If not using u-boot then the command line is in a separate file in nanda. |
| 21:40.20 | hno | if using u-boot then the environment is in the "env" nand partition. |
| 21:41.12 | rm | I don't have serial at the moment |
| 21:41.38 | rm | and it's an MK802, afaik it doesn't have serial RX (input), no? |
| 21:44.24 | lukestuts | hno: how do you change the kernel options that u-boot passes when booting from SD? |
| 21:49.23 | mnemoc | boot.scr? |
