| 00:13.55 | GeorgeIoak | Hoping you guys can let me know what I did wrong. Had a working SD card, decided to recompile kernel/modules, and am now stuck at "Waiting for root device /dev/mmcblk0p2..." |
| 00:14.15 | GeorgeIoak | card looks fine on computer |
| 00:14.43 | GeorgeIoak | if i plug/unplug mouse i can see it enumerate on the UART console |
| 00:15.18 | rz2k | libv: awesome! |
| 00:15.19 | aholler | be sure to not have the mmc/fs stuff as module. |
| 00:16.20 | GeorgeIoak | i didn't touch mmc/fs in the kernel compile but what could i check |
| 00:16.42 | GeorgeIoak | this has happened before so i think i'm doing something wrong but i need to save this card |
| 00:18.02 | ZaEarl | libv, I love you, man. |
| 00:18.30 | GeorgeIoak | i see these messages and i think on a good boot there are voltage readings from the axp209, regulator_init_complete: axp20_buck3: incomplete constraints, leaving on |
| 00:22.16 | GeorgeIoak | i see this early in the UART console:[mmc]: sunxi mmc controller using config : 0xb |
| 00:22.42 | GeorgeIoak | but then: pdev->id: 0 |
| 00:22.55 | GeorgeIoak | [mmc]: sunxi-mmc.0: pdev->name: sunxi-mmc, pdev->id: 0 |
| 00:23.30 | GeorgeIoak | the line ends with: off !! |
| 00:26.35 | GeorgeIoak | on some other boot tries i do see voltages on the AXP209 probe but I see mmc 3 power off !! (and MMC0 and MMC1 but nothing about MMC2) |
| 00:29.07 | GeorgeIoak | nevermind, seems like i've got a flaky sd card slot, pushing down on it allowed it to boot now. just what i need to happen ... |

| 00:33.51 | GeorgeIoak | torindel: thanks but i didn't think it was the actual sd slot that could be bad. i thought somehow i was copying wrong files or something and the kernel was just throwing that message |

| 13:42.16 | hramrach | when it's written in the law and the courts just ignore it .. |
| 13:42.52 | hramrach | there is lobbying to make it legal after the fact since so many nice but illegal patents are already granted |
| 13:45.09 | oliv3r | well i'm a paying supporter of the EFF, they should complain too! :p |
| 13:45.11 | bfree | hramrach: it's not that simple, those doing the interpretting of the law to apply it in the real world find that the words "as such" in the law open up a big can of worms and allow things "we" would deem as software patents |

| 15:38.50 | bfree | I know that, I meant who posted it to slashdot ;) |
| 15:53.17 | traeak | hehe libv |
| 15:53.18 | hansg | Turl, I've not actually tried overclocking, so maybe I'm wrong, but before my patch both the cpufreq_max as the scaling_max where 1008000000, and AFAIK you cannot set the cpu higher then cpufreq_max |
| 15:53.27 | traeak | your 2 and 3% are statistically aboutmeaningless |
| 15:53.34 | traeak | but it's cool anyways and thanks for all the hard work |
| 15:54.30 | hansg | But maybe I'm wrong and people are already overclocking through sysfs ? |
| 15:55.11 | hansg | Anyways I guess my patch should be split into 2, one to split cpufreq and scaling min_max defines, and change the scaing_min to 408 |
| 15:55.30 | hansg | And then maybe later another to make overclocking easier. Maybe ... |
| 15:56.12 | mnemoc | hansg: the main problem I see is that android doesn't sleep, it clocks down. so pushing the minimum higher will reduce battery life for them |
| 15:58.16 | mnemoc | a CONFIG_ would solve that. as we have different defconfig for both |
| 15:58.42 | hansg | mnemoc, there is sleep and there is sleep, unless android busyloops, or has very frequent wakeups when idle, the cpu will enter a deep powerstate, eliminating any power consumption differences from just clockfrequence changes, or so I expect |
| 15:59.02 | mnemoc | but surely the split of that patch is welcomed |
| 15:59.33 | hansg | mnemoc, so how about a patch to split cpufreq and scaling min-max into separate defines, and then a CONFIG_ option for setting scaling_min ? |
| 15:59.51 | mnemoc | sounds good |
| 16:00.26 | hansg | mnemoc, TBH I don't care about overclocking (at least not atm), that part of the patch was just a matter of "while I'm at it" |
| 16:01.35 | hansg | mnemoc, ok I'll put fixing that patch to your liking on my todo |
| 16:01.49 | hansg | mnemoc, feel free to merge the 2 display patches in the mean time :) |

| 17:50.10 | Welsh | Just come across this project and I am really interested. Have a few questions though, if someone could throw out answers or where i'd find more info. |
| 17:51.13 | Welsh | What hardware and cards are currently being worked on? Would a keyboard with a passthrough card simply have a usb hub inside it? |
| 17:51.39 | provel__ | wait.... lots of project here |
| 17:51.47 | Welsh | EOMA |
| 17:51.52 | provel__ | ok |
| 17:52.02 | Welsh | Sorry, should have stated that, but the topic said it so i was unsure |
| 17:52.16 | provel__ | I suppose that keybord has a little hub, yes |
| 17:52.40 | provel__ | linux kernel likely supports hubs, anyway |
| 17:52.43 | Welsh | Just thinking that the keyboard would be the simplest to produce as a proof of concept |
| 17:53.37 | provel__ | removing the hub and inserting the eoma? I doubt there's space enough |
| 17:54.16 | Welsh | I mean the keyboard could contain a hub. The EOMA would be a simple usb passthorugh with an single port on it |
| 17:55.16 | Welsh | I don't seem to be able to spell today |
| 17:56.10 | provel__ | hum... you want to connect eoma between a keyboard and a PC? I can't imagine nothing but bad things of that ^^' |
| 17:57.04 | Welsh | the EOMA wiki lists keyboard as one of the proposed form factors |
| 17:57.44 | mnemoc | Welsh: but those all-in-one keyboard things iirc |
| 17:57.48 | Welsh | It's simply a keyboard with a few extra usb's, but pull out the default card and put in a cpu card and you just have to connect a monitor |
| 17:58.05 | mnemoc | Welsh: so a computer without display on a single brick |
| 17:58.15 | Welsh | mnemoc: Yes |
| 17:58.54 | mnemoc | so your keyboard should also have rj45, sata and dvi/vga output |
| 17:59.25 | Welsh | It doesn't have to provide visual if that's on the cpu card? |
| 17:59.57 | Welsh | Sata is easy to do, with a sata to usb on the pasthrough card |
| 17:59.58 | mnemoc | the connectors on the external side of the eoma68 card are all optional |

| 18:01.12 | mnemoc | and so turn the lvds from the pins into dvi or similar |
| 18:01.44 | Welsh | I see what you're saying, but those ports will have no use without the cpu card. |
| 18:02.32 | mnemoc | eoma-based devices are no use without the cpu card |
| 18:02.53 | mnemoc | the passthrough is mostly a debugging tool |
| 18:02.56 | Welsh | Except as tv's, screens, etc |
| 18:03.07 | Welsh | I thought that was the idea |
| 18:03.41 | Welsh | Say you buy a screen, it just passes hdmi through to the lcd |
| 18:03.53 | Welsh | Has usb and a sata port too |
| 18:04.09 | Welsh | but then you can drop in a cpu card, and have an all in one pc? |
| 18:04.30 | Welsh | at least, that was the direction i got from the material I can find on it |
| 18:04.33 | Turl | your screen would have to be EOMA-enabled |
| 18:04.42 | Turl | ie have a EOMA slot where you can put your card in |
| 18:05.31 | Welsh | Turl: Yes |
| 18:05.55 | mnemoc | same with the keyboard, the brain is in the card, even if the card is a dummy |
| 18:06.09 | Turl | so you want something like http://anticultura.blogsome.com/images/sinclair_zx_spectrum.jpg |
| 18:06.24 | Welsh | I get that the brains are in the card |
| 18:06.26 | *** join/#arm-netbook voronaam (~avorona@159.153.138.99) |
| 18:06.59 | Welsh | mnemoc: but you said that without a cpu card the device is useless |
| 18:07.09 | Turl | it is |
| 18:07.19 | Welsh | the card does not need a cpu for you to use the device say, as a normal keyboard or screen |
| 18:07.39 | Turl | you'd need a special card |
| 18:07.44 | Turl | but what's the point then |
| 18:07.49 | mnemoc | a passthrough card counts as a dummy cpu card |
| 18:07.58 | mnemoc | but still a "cpu card" |
| 18:08.06 | mnemoc | without embedded cpu |
| 18:08.08 | Welsh | so it's more the terminology i've been using? |
| 18:08.21 | Welsh | I'd say it was an EOMA card |
| 18:08.36 | Welsh | especially if it didn't have a cpu |
| 18:08.38 | Welsh | hmm |
| 18:09.14 | Welsh | http://elinux.org/Embedded_Open_Modular_Architecture/EOMA-68/Passthrough |
| 18:09.17 | Turl | the point of EOMA cards is that they can be replaced so you can upgrade the "brain" |
| 18:09.24 | Welsh | it's called a "passthrough card" here |
| 18:09.59 | mnemoc | Welsh: but for the eoma-enabled device it's just another eoma card |
| 18:10.06 | mnemoc | no hdmi, but lvds |
| 18:10.14 | mnemoc | even if it originally comes from hdmi |
| 18:10.59 | Welsh | I'm confused as to what we're confused about now |
| 18:11.14 | mnemoc | :) |
| 18:11.36 | Welsh | I was specifically checking on the point: A keyboard with a passthrough card is a plain keyboard, perhaps with extra USB ports. Removal of the passthrough card and insertion of a CPU card turns the keyboard into a fully-functioning computer. |
| 18:12.17 | Welsh | As this would be a simple proof of concept build for me and would give me something to put a pcu card in when one is produced |
| 18:12.25 | mnemoc | yes, have the usb connected you'll get all the usb functionally in the usb of the passthrough |
| 18:12.33 | mnemoc | even if you "forget" to connect the other cables |
| 18:12.56 | mnemoc | in which case it's a fat keyboard with hub |
| 18:13.19 | Welsh | And from all the pictures of what the first cpu card will look like, i had assumed that they would provide a mini-hdmi out |
| 18:13.31 | Welsh | I get that you're saying this might not always be the case |
| 18:13.41 | mnemoc | the eoma68-a10 card is only one example of card |
| 18:14.03 | mnemoc | and all those "external" connectors are outside the scope of eoma68 |
| 18:14.45 | mnemoc | so the keyboard itself needs a dvi/vga connector |
| 18:15.21 | Welsh | which would require a chip inside the keyboard to convert the signals? |
| 18:15.24 | mnemoc | and do the corresponding magic over lvds |
| 18:15.27 | mnemoc | yes |
| 18:16.07 | Welsh | The wiki entry says devices are free to implement only some of the interfaces |
| 18:16.18 | Welsh | CPU cards must implement all though |
| 18:16.48 | Welsh | So a keyboard with no display output would be within EOMA |
| 18:17.05 | mnemoc | yes, you can. but it would be pretty pointless to make an "all-in-one"ish eoma keyboard which won't have display unless the card provides that "out of the standard" |
| 18:18.01 | mnemoc | because you can't assume the card will have any other video output beside the lvds on the eoma68 connector |
| 18:18.20 | mnemoc | even if some (like the a10-based one) has it |
| 18:18.26 | mnemoc | have* |
| 18:18.29 | aesok | ++ |
| 18:19.23 | Welsh | Maybe to start i could break out the pins for lvds inside the keyboard, and leave space for an addon that would provide video out |
| 18:19.43 | Welsh | to reduce initial cost |
| 18:19.46 | mnemoc | will it really make a $diff$? |
| 18:20.11 | Welsh | on a student budget, probably |
| 18:20.19 | mnemoc | people expects to be able to plug a display on an smart keyboard |
| 18:21.06 | Welsh | But including it as standard when there will be no output? |
| 18:21.59 | mnemoc | who would buy an eoma keyboard to only use it as standard usb keyboard? |
| 18:22.34 | mnemoc | by definition the "smart" keyboard will be more expensive than a normal dumb keyboard |
| 18:23.36 | Welsh | besides, wouldn't an lvds -> hdmi converter require hdmi membership? |
| 18:23.57 | Welsh | mnemoc: And this would just be a slightly better than dumb keyboard |
| 18:24.49 | Welsh | If i wanted to go for full price smart keyboard then yes, i could add those things. But i was going for base price proof of concept |
| 18:24.49 | mnemoc | make it dvi in hdmi connector (i.e. hdmi without audio) and not license is needed |
| 18:27.29 | mnemoc | student can carry something like http://support.lenovo.com/en_US/product-and-parts/detail.page?LegacyDocID=MIGR-73183 with the card and sata drive inside, and plug it to any display (vga, dvi, hdmi) and enjoy :) |
| 18:28.07 | Welsh | That would be the final idea, yea. |
| 18:28.54 | jelly-home | incidentally, that keyboard does not work with MK802 or cubie's android images properly |
| 18:29.07 | Welsh | I was going to use the initial keyboard with a raspberry pi or cubieboard, thus the display would be external |
| 18:31.15 | Welsh | My keyboard design without display out would also be useful for somewhere with chin clients or EOMA card screens, as you could still keep the storage in the keyboard, even wifi |
| 18:31.41 | Welsh | But i can see your point about adding a display out if not all cards are going to supply an external one |
| 18:32.46 | mnemoc | adding a battery would be nice too |
| 18:33.18 | mnemoc | a lipo is easy to make optional |
| 18:33.41 | Welsh | I had considered the option, as well as a EOMA card that made it into a blue tooth keyboard |
| 18:33.58 | Welsh | not sure i could do usb over bluetooth though |
| 18:35.40 | Welsh | are there any standards for wireless usb connections? |
| 18:37.11 | Welsh | There do seem to be some wireless usb hubs... looking expencive though |
| 18:38.21 | mnemoc | you'll probably have to export the different components as BT profiles |
| 18:38.27 | mnemoc | not usb as such |
| 18:38.41 | mnemoc | which doesn't really sound... fun |
| 18:39.44 | Welsh | http://www.bargainstock.co.uk/Product.asp?pid=3221 |
| 18:39.53 | Welsh | I'd need a cheaper way to do exactly this |

| 18:47.55 | Welsh | would probably use more power though. |
| 18:49.00 | mnemoc | if you can run the smart keyboard from battery and plugged to the wall you can offer pretty nice flexibility |
| 18:49.45 | mnemoc | even if you have a display available, finding a free outlet isn't normally easy |
| 18:50.03 | mnemoc | i mean, when using it on the go |
| 18:50.36 | Welsh | Yea. I was thinking about making it take 5v anyway, so it could be charged via usb |
| 18:51.28 | Welsh | It will basically be the laptop style dock without a screen with all these add ons |
| 18:51.44 | mnemoc | what about a more flexible input range and common dc connector? like 5.5/2.5mm 5-19V ? :) |
| 18:51.52 | Welsh | maybe i shall do a small one with less features for version one. |
| 18:52.22 | jelly-home | 5-19V?? :-) |
| 18:52.35 | Welsh | mnemoc: was going to have a second connector anyway. But i like 5v, it's so nice :P |
| 18:53.03 | Welsh | Especially if i'm using it with a cubie / pi, i can just use the same plug that normally runs that |
| 18:53.17 | mnemoc | jelly-home: good and inexpensive 5.5/2.5mm 12V/19V power adapters are very easy to find |
| 18:53.35 | mnemoc | and can charge your battery faster than 5V :p |
| 18:55.26 | mnemoc | while 5V power adapters tend of be crap unless they are absurdly expensive |

| 23:27.14 | Welsh | simple EOMA question. Could a low cost android phone be converted to a "franken-CPU-card" for testing? Since there are no CPU cards currently? |
| 23:29.19 | mnemoc | maybe you can build/sell the first passthrough cards? ;-) |
| 23:31.17 | Welsh | That would require me to know about psb design. :P Which i don't yet. I shall look into it though XD |

| 23:32.47 | Welsh | books on pcb design look expensive D: |
| 23:38.15 | mnemoc | around kicad you can probably find good free documentation to get started |
| 23:38.30 | mnemoc | and after all, the passthrough card is quite dumb |
| 23:39.09 | Welsh | It's simply mapping the pins to the outputs right? |
| 23:39.34 | mnemoc | + hdmi/lvds conversion, and the connectors |
| 23:39.39 | Welsh | yea |
| 23:39.51 | mnemoc | so it sounds like the perfect first pcb project ;-) |
| 23:46.14 | Welsh | Trying to find a pcb designer now :P |
| 23:46.40 | specing | haha |
| 23:48.48 | Welsh | eagle freeware allows me a large enough design for PCMCIA cards |
| 23:48.54 | Welsh | :) |
| 23:49.06 | mnemoc | Welsh: kicad? |
| 23:50.03 | Welsh | the kicad site doesn't seem to want to load for me |
| 23:51.10 | Welsh | but eagles 4" x 3" and 2 layers should be plenty for a passthrough, no? |
| 23:51.24 | mnemoc | `apt-get install kicad` |
| 23:51.41 | Welsh | Windows user :P |
| 23:51.48 | Welsh | gets into fire proof suit |
