| 02:11.05 | markvandenborre | I'm fiddling with an embedded a13 board |
| 02:11.18 | markvandenborre | just compiled in full HID support into the kernel |
| 02:11.46 | markvandenborre | (my first cross compile was amazingly easy) |
| 02:12.59 | markvandenborre | this HID device now works; I can verify that by catting /dev/input/event1 |
| 02:13.34 | markvandenborre | (random garble comes out of that every time I press the one key on this HID device) |
| 02:14.46 | markvandenborre | now I want to have this HID device hooked up into a small shell script that I wrote |
| 02:14.57 | markvandenborre | this shell script uses the "read" command quite often |
| 02:15.19 | markvandenborre | in other words, it expects an active terminal |
| 02:16.22 | markvandenborre | what would be the best way forward? change this script so that it picks up key press events from the HID device without being attached to it? |
| 02:16.53 | markvandenborre | auto spawn a terminal in /etc/inittab? |

| 03:18.04 | bsdfox_ | aren't there some unused timers on A10? |
| 03:18.17 | bsdfox_ | why are we using delay() |
| 04:18.02 | lkcl | <PROTECTED> |
| 04:18.32 | lkcl | one such circumstance, a mobile phone's capacitors for the power-up of a GSM Radio ROM simply weren't big enough |
| 04:18.39 | lkcl | so the bring-up sequence was: |
| 04:18.54 | lkcl | * pull GPIO for 5V line power |
| 04:19.01 | lkcl | * pull GPIO for 3.3V line power |
| 04:19.10 | lkcl | pull 2nd GPIO for 2nd 3.3V line power |
| 04:19.30 | lkcl | udelay(10) |
| 04:19.41 | lkcl | pull down the 1st 3.3V power |
| 04:19.47 | lkcl | udelay(10) |
| 04:19.52 | lkcl | pull down the 5V power |
| 04:19.56 | lkcl | udelay(10) |
| 04:20.00 | lkcl | pull them back up again |
| 04:20.03 | lkcl | udelay(10) |
| 04:20.09 | lkcl | pull the GPIO for reset up |
| 04:20.15 | lkcl | udelay 10 |
| 04:20.21 | lkcl | pull everything down again |
| 04:20.23 | lkcl | udelay 10 |
| 04:20.47 | lkcl | by this time, the on-board GSM radio ROM's capacitors had enough charge..... |
| 04:21.07 | lkcl | so it was then possible to do this sequence a *second* time, and the device would come up properly. |
| 04:21.38 | lkcl | you _could_ do all that with timers but it would be absolute hell, and completely non-obvious |

| 05:11.19 | bsdfox_ | lkcl, if you've got a dedicated timer for application it wouldn't be a big deal |
| 05:11.26 | bsdfox_ | and you wouldn't just be burning clock cycles |
| 05:12.06 | bsdfox_ | also, fuck that gsm module |
| 05:12.08 | lkcl | bsdfox_: for the complexity involved due to the asynchronous code that results it's often not worth it |
| 05:12.14 | lkcl | bsdfox_: :) |
| 05:12.26 | lkcl | this was for an HTC Smartphone (reverse-engineered). |
| 05:12.37 | lkcl | people kinda expected to be able to communicate using it :) |
| 05:12.55 | bsdfox_ | yeah that's the problem with reverse engineering |
| 05:13.28 | lkcl | ah no - in this case, that was direct reverse-engineering of the assembly files. |
| 05:13.29 | bsdfox_ | there's probably a straight forward approach to initializing the radio that doesn't require all the funky steps |
| 05:13.38 | lkcl | this was that the... no, it didn't, that's the point. |
| 05:13.55 | lkcl | i examined the assembly code: that was what they were forced to do. |
| 05:14.15 | lkcl | istrc that WIFI was similar |
| 05:14.17 | bsdfox_ | which radio did it use? |
| 05:14.21 | lkcl | it was just poor hardware design |
| 05:14.38 | lkcl | i thiiink.... it was an ericsson chipset. |
| 05:15.09 | lkcl | it just pulled so much current at startup that it couldn't cope |
| 05:15.17 | bsdfox_ | from what I've seen cell phone companies invest much more in hardware than software |
| 05:15.39 | bsdfox_ | lkcl, polling is fine if the code is designed for it |
| 05:15.41 | lkcl | .... qualcomm is run by three lawyers :) |
| 05:16.07 | bsdfox_ | lkcl, qualcomm employs some very good engineers |

| 14:18.47 | lkcl | i checked the schematics that wits-tech designed for us, what they've done is connected the 5V power onto the AXP209's "AC-IN" input :) |

| 14:36.30 | lkcl | yeah as this is being driven by aaron (kde "spark" aka "vivaldi" tablet) we need to listen to his requirements. |
| 14:36.49 | lkcl | they have done a lloooooot of reviews of tablets. an insaaaane amount of testing. |
| 14:37.33 | specing | so this is yet another case of when hardware is being designed for software? |
| 14:38.59 | lkcl | specing: no. this is a case of meeting customer requirements, where customer has been through absolute hell trying to get any kind of reliable hardware *at all* out of china suppliers |
| 14:39.31 | specing | heh :) |
| 14:39.35 | lkcl | what he's found is that the 1st batch is ok but it all goes to shit when they try to redesign the PCB *without* telling them what's going on. |
| 14:40.24 | lkcl | i don't know for sure but one or two companies might even have tried to sell him a unit with a totally different processor - it wouldn't surprise me |
| 14:40.50 | lkcl | and it's like, "nooo, we neeeeed that CPU because we have the F*****G SOURCE CODE FOR IT" |
| 14:41.08 | lkcl | we don't WANT your android GPL-violating turd-in-a-can |
| 14:41.37 | lkcl | but yeah, it is more than that: the build qualities have just been so questionable that he's got fed up with it |

| 14:42.15 | jinzo | and they provide some interesting stuff and quality |
| 14:42.42 | lkcl | jinzo: with GPL-violating linux kernels because they're dealing with AMLogic? |
| 14:43.13 | jinzo | lkcl, they have some older A10 based offerings ;) |
| 14:43.29 | lkcl | jinzo: aaron's been through that one already. they managed to get supply of the linux kernel source code, originally, by one of the *engineers* violating his own company's NDA. |
| 14:43.34 | RaYmAn | allwinner isn't exactly NOT GPL violating though - even if they seem to have gotten slightly better. |
| 14:43.36 | jinzo | The elf II that I ordered for a friend was amazing (for the price ofcourse) |
| 14:43.54 | lkcl | that was one of the engineers working for the ODM. |
| 14:43.58 | jinzo | and it has the usual A10 stuff in it. |
| 14:44.05 | lkcl | great. |
| 14:44.13 | lkcl | now if they'll convert it to EOMA-68, we're good to go. |
| 14:44.21 | lkcl | do you have contact details for them? |
| 14:44.48 | jinzo | and it's not in their active offering anymore - so they could be more inclined to sell it. |
| 14:45.37 | lkcl | well i'm more looking for companies that are willing to redesign casework |
| 14:45.55 | lkcl | and use the PCB design i've been working on |
| 14:46.05 | jinzo | unfortunately no, sales@ainovo.com looks like. |
| 14:46.47 | jinzo | Like I said, I don't have any particual experiance with it - but found the quality of the Elf II really good for the price point (nothing else has came close - and I tried quite some) |
| 14:48.56 | jinzo | But their website is.... an image. This looks like a semi official shop: http://www.ainol-novo.com/ |

| 22:35.49 | slapin_ | hno: /me fails to make reading work |
| 22:38.30 | slapin_ | hno: nand dump reads something weird... |
| 22:41.33 | mnemoc | wrongly initialized dma or something like that? |
| 22:45.17 | slapin_ | gives up for today, it seems it works differently from what I thought |
| 22:45.38 | mnemoc | tried the boot0 variant? |
| 22:46.08 | mnemoc | or it's the same thing? |
| 22:47.03 | slapin_ | mnemoc: which boot0 variant? |
| 22:47.21 | mnemoc | https://github.com/linux-sunxi/linux-sunxi/tree/wip/lichee3-sunxi/import-a10s-sdk/drivers/block/sun5i_nand/src/boot0 |
| 22:48.39 | hno | slapin_, I suspect the data is randomized. |
| 22:51.23 | hno | slapin_, http://fpaste.org/8bTE/ is a full trace of allwinner nand driver reading the partition table. |
| 22:51.49 | hno | whole initialization sequence to bootwait prompt. |
| 22:52.51 | hno | keep in mind that it uses DMA for bulk data transfer and those transfers are not visible, only command sequence and direct SRAM read/writes. |
| 22:53.41 | slapin_ | hno: they always use DMA, can't see how to read without DMA |
| 22:54.05 | hno | mnemoc, it's pretty much the same code as in the bigger driver, just with all other cruft cut out. |
| 22:54.23 | slapin_ | mnemoc: low level part is the same |
| 22:54.23 | hno | slapin_, probably works polling the IO register. |
| 22:54.24 | mnemoc | ok |
| 22:54.52 | slapin_ | hno: IO_DATA always returns 0, will try again... |
| 23:00.03 | slapin_ | hno: no, IO_DATA always reads 0 |
| 23:00.27 | slapin_ | hno: probably it needs to be enabled somehow, but dunno |
| 23:01.21 | slapin_ | also, is it possible, that during read it detects command code and does something different based on it? |
| 23:02.05 | slapin_ | I tried to do command and read data afterwards, it reads some crap (byte 0x30) |
| 23:02.53 | slapin_ | I don't see why reading is different from e.g reading of ID. |
| 23:03.17 | slapin_ | from POV of NAND chip it is the same, just different command code, |
| 23:03.54 | slapin_ | I tried to program it similar, but failed. |
| 23:04.56 | slapin_ | just normal sequence 0x00 CCCRR 0x30 -> DDDDDD doesn't work. |
| 23:06.20 | slapin_ | just if I had oscillooscope or logic analyser.... :( |
| 23:13.11 | focus_it | slapin_: cheap http://www.ebay.co.uk/itm/New-ARM-NANO-DSO201-Oscilloscope-Mini-Storage-Digital-Pocket-Sized-Portable-Kit-/270972259947?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item3f17348e6b |

| 23:48.28 | Mehhh_ | Hey, does it matter if the vfat partition is exactly 83 sectors? |
| 23:48.41 | Mehhh_ | or can I just set it to 10MB or something? |
| 23:55.24 | libv | all that matters is that the spl and u-boot bits that you dd are in the proper location |
| 23:55.27 | libv | uboot can take it from there |
