| 01:47:40 | Sammy | Oh~ Hi ~ Yo ~ |
| 09:43:09 | seletz | morning |
| 12:04:22 | Sammy | erikm: a question ... |
| 12:04:31 | erikm | hmm? |
| 12:05:09 | Sammy | erikm: from board assabet when gpio 17 low then led will be on right ? |
| 12:06:32 | erikm | Sammy: IIRC yes |
| 12:08:51 | Sammy | if that so , ledinit: |
| 12:08:52 | Sammy | ldr r0, GPIO_BASE |
| 12:08:53 | Sammy | ldr r1, LED |
| 12:08:54 | Sammy | str r1, [r0, #GPDR] /* LED GPIO is output */ |
| 12:08:55 | Sammy | str r1, [r0, #GPSR] /* turn LED on */ |
| 12:08:56 | Sammy | mov pc, lr |
| 12:08:57 | Sammy | then this line will be use GPCR right ? |
| 12:09:16 | Sammy | not GPSR ?! |
| 12:10:54 | erikm | yes, assabet has reversed logic for the LED |
| 12:11:29 | erikm | all other boards need to *SET* the GPIO in order to turn a LED on, assabet needs to *CLEAR* the GPIO |
| 12:11:46 | Sammy | so when blob goes here then led won't light right .? |
| 12:12:09 | erikm | *nod* |
| 12:12:15 | erikm | don't bother |
| 12:12:28 | Sammy | ok :) |
| 12:12:34 | erikm | in case of error, the blinking still works |
| 12:12:49 | Sammy | yeap .... |
| 12:13:47 | Sammy | erikm: do you have any experience change some h/w from ipaq ? like SDRAM |
| 12:14:32 | erikm | no, I didn't change anything on my ipaq |
| 12:16:23 | Sammy | from your solding experience , will you do that ? |
| 12:16:40 | Sammy | like change ram from 32 to 64 ... |
| 12:17:16 | erikm | depends on the DRAM |
| 12:17:31 | Sammy | some of my friend do that before , and work fine :) |
| 12:17:44 | erikm | if it is BGA I wouldn't do it |
| 12:17:55 | Sammy | http://www.pdaordie.com/newsdetail.asp?NewsID=253 |
| 12:18:06 | Sammy | and |
| 12:18:14 | Sammy | http://www.pdaordie.com/newsdetail.asp?NewsID=255 |
| 12:18:46 | Sammy | I know , no one can do it by himself from BGA .... |
| 12:19:27 | Sammy | maybe you can't see the word , but the picture is very clear |
| 12:20:06 | Sammy | and this page is some of my friend in taiwan play something on ipaq , |
| 12:20:59 | Sammy | I would like change on my ipaq too , but I afread that can't run bootldr , kernel ,etc... |
| 12:21:07 | erikm | hmm, removing then RF shielding from the CPU and DRAM can be pretty hard |
| 12:22:08 | Sammy | need some tool , here in chinese we call that hair dryers |
| 12:23:25 | Sammy | I don't know how to say that words ? |
| 12:24:02 | Sammy | so if I change that , should I need to change anything on bootldr to run it ? |
| 12:24:04 | erikm | hot air gun, IIRC |
| 12:24:21 | erikm | bootldr doesn't autoprobe memory |
| 12:24:25 | erikm | blob does |
| 12:25:00 | Sammy | hot air gun ... oh~ |
| 12:26:46 | Sammy | erikm: but in this time bootldr can boot WinCE and linux .... |
| 12:27:07 | Sammy | I hope someday blob also can do that too... |
| 12:34:05 | Sammy | erikm: what do you think if blob can loading from ethernet via CF even PCMCIA ? |
| 12:34:58 | erikm | on the ToDo list |
| 12:35:09 | erikm | will go in for blob-2.0.6 |
| 12:35:55 | Sammy | Amm... so what's software should we need ? |
| 12:37:24 | Sammy | I mean in our client , what software should need to help file transfer ? |
| 12:37:41 | seletz | erikm: hi |
| 12:38:23 | Sammy | hello seletz :) |
| 12:44:27 | erikm | Sammy: what do you mean with "client"? |
| 12:44:31 | erikm | hello seletz |
| 15:16:20 | prpplague | seletz: morning |
| 15:16:48 | seletz | prpplague: hi ya |
| 15:17:06 | seletz | prpplague: got new ideas? |
| 15:18:43 | seletz | playing "boot with a ro root fs" .... |
| 15:35:02 | prpplague | seletz: ya been tossing around some ideas |
| 15:35:27 | prpplague | seletz: let me finish this call and i'll chat with you about them |
| 15:36:24 | Sammy | erikm: I mean like when we download kernel and ramdisk , need " uuencode " |
| 15:37:12 | Sammy | so if we downlaod via ethernet CF card maybe we need some s/w another terminal |
| 15:37:29 | Sammy | to transfer them ... |
| 15:37:38 | erikm | Sammy: the idea is to do that automatically |
| 15:37:39 | Sammy | or something like that ... |
| 15:38:09 | Sammy | oh , |
| 15:39:29 | Sammy | erikm: does blob ever think about dual boot ? |
| 15:39:44 | erikm | Sammy: dual boot between? |
| 15:40:16 | Sammy | or multi boot between linux and linux or linux and Wxx |
| 15:40:44 | erikm | Sammy: the idea is that the param list would allow you to set the preferred kernel download method |
| 15:41:12 | erikm | I don't do any Wxx, so I really have no idea how to boot such a beast |
| 15:41:41 | Sammy | or one in flash , another in CF or external storage ... |
| 15:53:13 | prpplague | seletz: ok, back |
| 15:53:30 | prpplague | seletz: here's what i'm thinking |
| 15:54:22 | prpplague | seletz: a sa-1110 board with flash, ram, and ucb1200 |
| 15:54:59 | prpplague | seletz: the board would be sized to fit in a standard off-the-shelf pactech abs plastic box |
| 15:55:32 | prpplague | seletz: the rest of the pcb would be breadboard style perf |
| 15:57:38 | prpplague | seletz: with the rest of the sa signal brought out to some sort of easy to use connector such as an idc header |
| 15:59:20 | prpplague | erikm: what do you think? |
| 15:59:36 | prpplague | erikm: any suggestions? |
| 16:00:39 | erikm | prpplague: sounds cool |
| 16:00:56 | erikm | prpplague: hint: get the balloon2 and put it on some kind of bread board |
| 16:01:40 | prpplague | erikm: where can you purchase a balloon2? or are you saying just use the balloon2 design? |
| 16:01:58 | prpplague | http://www.tekoenclosures.com/enclosures/handheld.htm |
| 16:02:24 | seletz | prpplague: one moment pls |
| 16:02:29 | prpplague | seletz: np |
| 16:02:56 | seletz | prpplague: ahhhh, YES! |
| 16:03:58 | seletz | prpplague: though i will talk to the rapid-prototyping people. Display is still a issue with those cases. |
| 16:04:27 | seletz | prpplague: and what about the keyboard? |
| 16:05:20 | prpplague | seletz: yes i've not worked that out yet |
| 16:05:35 | seletz | prpplague: sorry, but what's a "breadboard"? |
| 16:05:50 | erikm | prpplague: for balloon2, see http://www.lart.tudelft.nl/gallery/projects/ |
| 16:06:12 | prpplague | seletz: guess thats a US tech slang.... |
| 16:06:29 | prpplague | erikm: ya i've dl'd the specs and have been looking them over |
| 16:06:41 | erikm | seletz: no, it's not US tech slang |
| 16:07:16 | prpplague | seletz: https://www.jameco.com/cgi-bin/ncommerce3/ProductDisplay?prmenbr=91&prrfnbr=3634&cgrfnbr=501&ctgys= |
| 16:07:45 | erikm | seletz: bread board is an board on which you can build standard .1 inch through hole projects |
| 16:08:04 | erikm | seletz: pretty nice until the contacts wear out :( |
| 16:08:30 | prpplague | seletz: thats what it traditionaly thought of as a breadboard, however something like this is more of what i'm talking about https://www.jameco.com/cgi-bin/ncommerce3/ProductDisplay?prmenbr=91&prrfnbr=2722&cgrfnbr=501&ctgys= |
| 16:08:44 | seletz | prpplague: ahh, those white prototype boards? x/y type connectors? |
| 16:09:34 | seletz | ?? |
| 16:09:36 | seletz | ugh |
| 16:10:06 | seletz | ah, ok. |
| 16:10:10 | seletz | i see |
| 16:11:14 | prpplague | wahoo, my maxim samples have arrived |
| 16:11:27 | seletz | prpplague: actually exatly this was my idea: build a base cpu module with just enough to run linux. Have all io and processor pins accessible through connectors. mount it on a base board, which can contain for ex. PCMCIA, Ethernet and so on. |
| 16:12:09 | seletz | prpplague: should fit easy into those cases. |
| 16:16:52 | prpplague | seletz: ya sounds good |
| 16:31:14 | prpplague | seletz: what are your feelings about having the 4x4 keyboard matrix? |
| 16:35:01 | seletz | prpplague: i would not like a membrane keyboard. |
| 16:36:20 | seletz | prpplague: I'll have a meeting in munich on wednesday. Perhaps the cases can be modified to have a real keyboard. |
| 16:36:37 | prpplague | seletz: real it what way? |
| 16:36:53 | seletz | prpplague: read => non-membrane. |
| 16:37:22 | prpplague | seletz: i gathered that, but i'm not sure what other choices we'd have |
| 16:38:29 | seletz | prpplague: i'd like to have a keyboard like those in IR remote controls (sorry, i dont know the exact term). Made of rubber, you know them. |
| 16:39:00 | prpplague | seletz: ya i know the one |
| 16:39:13 | seletz | prpplague: we would in any way have to somehow modify the case for the display. |
| 16:39:51 | seletz | prpplague: agreed? |
| 16:40:19 | prpplague | seletz: i'd like to keep the modifications down, maybe we can find a standard case that will support the lcd better |
| 16:40:27 | prpplague | https://www.jameco.com/cgi-bin/ncommerce3/ProductDisplay?prmenbr=91&prrfnbr=5124&cgrfnbr=501&ctgys= |
| 16:40:43 | seletz | looking |
| 16:41:03 | seletz | prpplague: cool |
| 16:42:39 | seletz | prpplague: well, if we would take something like this, things woudl get quite easy: two rectangular holes in the upper part of the case. |
| 16:44:07 | prpplague | http://www.pactecenclosures.com/ |
| 16:44:14 | prpplague | check out some of those cases |
| 16:45:12 | prpplague | seletz: ya two holes and maybe a plastic silk screen to go over the panel to cover screw holes and such |
| 16:47:03 | prpplague | seletz: check out the ts model |
| 16:47:38 | seletz | have it |
| 16:48:07 | prpplague | seletz: you've got one of the TS cases? |
| 16:48:33 | seletz | no found it on their web page ... |
| 16:48:39 | prpplague | ahh |
| 16:48:40 | Sammy | later |
| 16:48:46 | prpplague | Sammy: later |
| 16:48:52 | seletz | bye |
| 16:49:30 | seletz | prpplague: the monochrome display i have here would probably quite easy fin in. |
| 16:49:48 | seletz | s/fin/fit/ |
| 16:50:38 | seletz | 13.4x9.5 cm |
| 16:51:45 | prpplague | seletz: ya and i have some kyocera color displays that would fit as well |
| 16:54:07 | seletz | prpplague: do you want those cases for prototype or for release models? |
| 16:57:43 | prpplague | seletz: if they can be easily modified to do the job, why not use them? |
| 16:58:57 | seletz | prpplague: people like to buy cute products? |
| 16:59:43 | prpplague | seletz: true |
| 16:59:59 | prpplague | seletz: i'm shooting for flexible and cheap |
| 17:00:07 | seletz | prpplague: me too. |
| 17:00:08 | prpplague | seletz: KEU-5LP , that one is cute lol |
| 17:00:21 | seletz | googleing |
| 17:00:38 | prpplague | seletz: XPL |
| 17:01:43 | prpplague | man there are lots of possible cases there |
| 17:02:55 | prpplague | seletz: hmm, CR-48 |
| 17:03:35 | seletz | prpplague: yup. the XPL are cool. battery cases. |
| 17:04:29 | seletz | prpplague: want some chip card reader built in? |
| 17:05:39 | prpplague | seletz: its a plus, but nothing nessary |
| 17:05:53 | prpplague | seletz: POS is always of interest to the managment |
| 17:06:51 | seletz | argh. my f***ing initrd doesn't work anymore. GRRRR |
| 17:08:06 | prpplague | doh |
| 17:08:44 | prpplague | TR-9VB/2AA |
| 17:09:06 | prpplague | that one has enough room for two pcbs and has a nice layout for keyboard and lcd |
| 17:10:14 | prpplague | seletz: what kind of price range do you think we can get for the core board with sa-1110,16mb flash,32mb ram? |
| 17:11:16 | seletz | prpplague: Well, i think we should get around $300. Quite a guess right now, but that would be reasonable. |
| 17:12:23 | seletz | prpplague: w/o PCMCIA and display, no power regulation etc |
| 17:12:36 | seletz | prpplague: and no ethernet. |
| 17:12:41 | seletz | prpplague: CORE board. |
| 17:13:37 | prpplague | seletz: so should expect to pay around $300 per unit for manufacturing? |
| 17:15:04 | seletz | prpplague: just the board. But wail 'till i had the meeting at wednesday. |
| 17:15:14 | seletz | s/wail/wait |
| 17:15:20 | seletz | please |
| 17:15:21 | seletz | :) |
| 17:15:26 | prpplague | lol ok |
| 17:17:04 | seletz | prpplague: But i think we'll definitely able to beat the price of the sample device. |
| 17:17:51 | seletz | prpplague: what do you think? |
| 17:18:21 | prpplague | seletz: sounds good as a start |
| 17:18:39 | seletz | i meant the intermec stuff. |
| 17:20:41 | seletz | But they look _really_ cute. The 700 series i mean. |
| 17:22:28 | prpplague | seletz: ya well i've been talking to management and the hardware staff, and i think the project might take a little different direction |
| 17:22:43 | seletz | prpplague: whic one? |
| 17:23:25 | prpplague | seletz: i think they are more interested now in making a generic device that can be used for alot of commercial application |
| 17:23:46 | seletz | prpplague: ah, ok. Suits me. |
| 17:23:50 | prpplague | seletz: i.e. configurable |
| 17:24:01 | prpplague | seletz: i've got to work out some more details |
| 17:24:02 | seletz | prpplague: HW-configurable? |
| 17:24:06 | prpplague | seletz: ya |
| 17:24:50 | seletz | prpplague: ah. different options, different hw, different case but same base system, i.e. Linux and StrongARM core board. cute. |
| 17:25:30 | seletz | prpplague: so the goal is to keep the core HW board as little as possible? |
| 17:25:51 | seletz | prpplague: to have more options for cases etc. |
| 17:25:53 | prpplague | seletz: ya, we found this over the weekend |
| 17:26:42 | seletz | prpplague: But still a hand-held type of product, i.e. battery, no power cords or external ac adaptor |
| 17:27:00 | seletz | prpplague: thus "low power" |
| 17:27:29 | prpplague | seletz: http://www.keith-koep.com/trizeps.html |
| 17:27:56 | seletz | looking |
| 17:28:08 | prpplague | seletz: ya we'd want it to be low power but have the option to use an ac adaptor |
| 17:28:47 | seletz | prpplague: price? |
| 17:28:53 | seletz | oh |
| 17:29:15 | prpplague | seletz: the base unit runs about $195EU |
| 17:29:30 | seletz | just saw it |
| 17:29:57 | prpplague | seletz: what do you think? |
| 17:30:36 | seletz | cheap |
| 17:31:43 | seletz | to be honest, hard to beat. |
| 17:32:51 | prpplague | seletz: ya thats what i was thinking |
| 17:33:04 | seletz | specially if one thinks: you could probably build a base board to fit those DIMM boards which hold all trizeps variants, i.e. 16/16 16/32 and so on |
| 17:33:05 | prpplague | seletz: maybe we should just design something around their core? |
| 17:33:49 | seletz | prpplague: well, the extension boards look not so good OTOH. |
| 17:34:02 | seletz | prpplague: well, that's what i think now. |
| 17:35:02 | seletz | prpplague: lets design base boards which suit your needs and put those triceps things on it. |
| 17:35:13 | prpplague | seletz: ya their boards didn't look very good, and the price was way too high |
| 17:35:34 | prpplague | seletz: thats what i'm thinking as well |
| 17:36:03 | prpplague | seletz: since your closer to that area, you want to feel out those guys and see if they are stable? |
| 17:36:08 | seletz | well well. BUT let me nevertheless talk to my buddies at wednesday. |
| 17:36:37 | seletz | prpplague: i even think to order a dev board. Those look good. |
| 17:37:05 | seletz | prpplague: well, lets see .... |
| 17:37:09 | seletz | looking |
| 17:37:47 | seletz | ugh |
| 17:37:59 | seletz | they have cotulla trizeps |
| 17:38:36 | seletz | PXA250-400 |
| 17:38:42 | seletz | trizeps II |
| 17:48:46 | seletz | prpplague: just submit a request for docs on tose trizeps. |
| 17:59:13 | seletz | prpplague: still there? |
| 17:59:44 | prpplague | seletz: ya sorry, working on a customers system |
| 18:00:39 | seletz | prpplague: np, we'll see after wednesday. Have just skimmed the trizeps doc, they look good. We'll see. |
| 18:12:48 | prpplague | seletz: ok sounds good, i'm headed to a conference in austin, won't be back till thursday |
| 18:14:39 | seletz | prpplague: ok, see ya |
| 18:16:54 | seletz | going home |
| 18:16:59 | prpplague | seletz: night |
| 18:17:12 | seletz_home | prpplague: bye |
