| 20:28.21 | hno | I don't get why one would want an EC in an A10 design, unless it's also the keyboard controller. But the A10 can also act as keyboard controller. |
| 20:28.36 | L84Supper | I'll find out later |
| 20:29.12 | L84Supper | maybe they didn't place the ESD parts down since it's so awful you really don't want to even use it |

| 21:25.15 | hno | The dram_para section looks very odd. |
| 21:26.54 | hno | plus that JTAG is also enabled on PF which collides with SDCARD usage, but that should not have any effect on SPL. |

| 21:31.47 | rm | with exactly the same OS image still on it |
| 21:31.50 | rm | and it didn't work |
| 21:33.51 | mnemoc | but there could be 512 meles needing a different initializatin, isn't it? |
| 21:34.28 | mnemoc | dram i mean |
| 21:35.29 | mnemoc | hipboi_ may now |
| 21:40.09 | hno | Yes. DRAM setup is a bit messy. If the board is using significantly different DRAM then SPL would not be able to load u-boot. |
| 21:40.35 | hno | and the dram_para section in script.bin from the failing board looks very odd. |
| 21:42.14 | hno | maybe the livesuite DRAM probing mentioned for A13 is also applied to A10 in newer releases which would explain why it's not in script.bin. If so then we need to get boot0/boot1 from the NAND to find actual DRAM parameters. |
| 21:43.21 | mnemoc | do we know to do that from `fel` yet or only from extracted livesuite images? |
| 21:43.36 | hno | Ah, nice. The EOMA68 A10 boards will have almost full GPIO capability. |
| 21:43.43 | hno | mnemoc, neither. |
| 21:45.12 | hno | apparently livesuite patches boot0/boot1 on the fly when programming the flash. |
| 21:45.39 | hno | no idea how phoenixcard is supposed to work with those firmwares. |
| 21:46.17 | hno | phoenixcard needs working DRAM parameters for the SDCARD. |
| 21:46.33 | hno | and can't probe the target board. |
| 21:47.25 | mnemoc | the best way for us i think is to find the magic address to dump using `fel` |
| 21:47.43 | hno | it's not a magic address. |
| 21:48.31 | hno | boot0 & boot1 is in the first erase blocks of the first NAND. |
| 21:49.40 | hno | but neither kernel NAND driver or u-boot NAND driver exposes raw NAND access. Only logical NAND access with block translation layer. |
| 21:50.23 | mnemoc | hipboi!!! |
| 21:50.35 | mnemoc | :( |
| 21:51.18 | hno | Well, the raw nand access layer is obviously there in the driver, but only accessed via the translation layer. |
| 21:51.52 | mnemoc | it's not the nicest driver to research... |
| 21:52.11 | hno | there is also a simplified raw nand access layer with comments sayint it's for u-boot to access the boot area, but have not got those to work. |
| 21:56.12 | hno | the driver is not that bad to research. |
| 21:57.22 | mnemoc | nicer than the disp drivers for sure |

| 22:33.03 | xenoxaos | hno, back to the DRAM on different boards not allowing things to load.... if the timings in the SPL were close to the actual timings of the dram, BUT NOT quite right, would uboot load intermittently/kernel loading be completely unreliable? |
| 22:36.10 | hno | Not sure. |
| 22:37.39 | hno | penguin42, MPEG Transport Stream interfaces, for DVB intefacing etc. |
| 22:38.16 | penguin42 | hno: Hmm, so yeh I've come accross MPEG Transport streams, but I've never seen an interface on a CPU for it - what do they look like from software? |
| 22:39.00 | hno | Unknown. All I know is that the A10 contains MPEG TS demultiplexers. |
| 22:39.33 | hno | there is no driver in the kernel sources that I am aware of. |
| 22:39.55 | penguin42 | hno: Interesting, I can see why - MPEG is a pain to decode in software, it's all stupidly aligned bit strings |
| 22:40.55 | hno | I think you can even make them feed VE directly, enabling decode without touching the ARM core. |

| 22:43.04 | hno | ping continues as long as interrupts works basically. |
| 22:43.09 | rm | want 500MB (524288000 bytes) |
| 22:43.09 | rm | got 500MB (524288000 bytes), trying mlock ... |
| 22:43.12 | rm | and that's all |
| 22:43.26 | rm | can't ^C it, can't ssh again |
| 22:44.20 | hno | Have you tried with just the first mem block? |
| 22:44.38 | rm | yeah, I will try now |
| 22:45.46 | rm | but I verified it has 2x512MB RAM chips |
| 22:46.28 | rm | and 2nd "but": even the Boot0 has "RAM: 512MB" |
| 22:47.19 | hno | Then it only configured 512MB in the DRAM controller. |
| 22:49.16 | hno | boot0 reads DRAM configuration from a header section in boot0. In the tools I have seen this header section is populated from script.bin when the firmware image is built. |
| 22:49.49 | hno | but the dram_para section in your android version seems empty? |
| 22:49.56 | rm | hm, so I basically have a firmware image for a 512MB board |
| 22:50.22 | hno | but a boot command line for 1G board? |
| 22:50.40 | *** join/#arm-netbook tuliom (~tuliom@186.214.73.165) |
| 22:50.48 | rm | this is supposedly an 1G board |
| 22:50.59 | rm | maybe I should find a different firmware |
| 22:51.04 | hno | From where is that boot command line? |
| 22:51.14 | rm | I hardcoded it into my kernel |
| 22:51.20 | hno | Ok. |
| 22:52.30 | hno | So you livesuite flashed it, and then replaced kernel & root? |
| 22:53.39 | hno | Yes, you need a 1G firmware for a 1G board, unless the automatic probing & detection by livesuite on A13 applies to later versions for A10 as well. |
| 22:54.56 | hno | Actually you need a firmware which is for your exact board type. Cross-flashing is only possible between devices with exact same DRAM configuration. |
| 22:58.39 | rm | I flashed it, then replaced linux.ini and added bImage |
| 22:59.02 | rm | and the bImage has "root=/dev/mmcblk0p2" hardcoded |
| 23:00.38 | rm | okay, now running with a 512MB kernel, 317MB available, testing 275MB - seems fine (at least does not fail/lockup instantly) |
| 23:08.11 | penguin42 | watches the A10 factory video - I'm always amazed by how much manual stuff is still in all this |
| 23:09.23 | specing | robots are expensive |
| 23:10.14 | penguin42 | and probably harder to train on anything less than vast production runs |
| 23:10.19 | rm | imagine if you had to sit 10 hours a day fitting widgets into gadgets |
| 23:10.38 | rm | and then feel grateful that you have your current job / living conditions |
| 23:10.56 | rm | s/10/16/, maybe |
| 23:11.27 | penguin42 | someone has at least given them fume extractor fans |
| 23:11.53 | rm | also there's no "the" video, I know at least three |
| 23:12.33 | penguin42 | http://armdevices.net/2012/06/18/jwd-7-allwinner-a10-tablet-factory-tour/ is the one I'm currently going through |
| 23:12.59 | rm | http://armdevices.net/category/factories/ |
| 23:13.40 | hno | penguin42, yes, but even in the most fancy of the factories they don't have any good lamps. |
| 23:14.14 | penguin42 | hno: That seems an odd economy; you'd think that would make a big difference to the number of screw ups |
| 23:16.43 | penguin42 | heck, the mk802 one is a bit more basic - a guy hand screen printing (literally screen with paint on) each individual one |
| 23:17.42 | rm | yes, I was amazed by this |
| 23:18.09 | rm | one would think a simple matter like painting a hunk of plastic into one solid color would be automated |
| 23:18.29 | penguin42 | yeh; or even if you were going to do it manually you could do say 5 at a time |
| 23:18.53 | rm | I don't remember if it's visible that he does 1 at a time |
| 23:19.01 | penguin42 | nod it is |
| 23:20.02 | penguin42 | http://www.youtube.com/watch?feature=player_embedded&v=rkR6_7cw4p8#! about 1:40 |
| 23:21.00 | penguin42 | if you're going to want to shave pennies off stuff that just would seem so easy |
| 23:22.04 | specing | A funny thing happened with the industrial revolution: first they started replacing human workers with machines, then they just move everything over to china |
| 23:22.11 | hno | penguin42, they only have one guy doing paint job, and that's likely the only task he is good at doing. Seem to keep up fine with the production rate. |
| 23:22.24 | *** join/#arm-netbook nibb (~jyuyu@7.188.218.87.dynamic.jazztel.es) |
| 23:22.59 | penguin42 | hno: Shrug, I doubt he couldn't do some of the other tasks - like the nice girl who basically just wipes a screen |
| 23:24.01 | penguin42 | specing: The interesting question is what happens next, as the chinese get more prosperous and want to get paid more, does the production move to the next cheapest country or do they pick up some more mechanisation |
| 23:53.05 | hno | rm, confusing. Seems same firmware is used on MK802 and MK802+? |
