| 13:46.19 | mnemoc | openning the chitech again |
| 16:01.37 | SQlvpapir | lkcl, I think I got a bounce on a mail sent to lkcl@lkcl.net, but since I'm using a smarthost the massage is not quiet clear. anyway bottom line was "I'd be happy to put in ~180USD including the SO-DIMM." |
| 16:02.01 | lkcl | SQlvpapir, great - that's absolutely fantastic. |
| 16:02.09 | lkcl | what's your email again? |
| 16:02.45 | lkcl | teis isn't it |
| 16:07.29 | SQlvpapir | yup, lkcl@lkcl.net down? - should I use your google hosted address? |
| 17:26.37 | mnemoc | lkcl: I took a full set of the pictures, my netbook includes the switch and the vga controller. you can download the "raw" bunch at http://geeks.cl/projects/chitech/chitech-mnemoc-2010-04-02.tar.bz2 |
| 18:07.06 | lkcl | SQlvpapir: no it's not down, the spam filtering is very very strict. i usually have to white-list people. |
| 18:07.12 | lkcl | mnemoc: ooo, you staaar. |
| 18:09.52 | mnemoc | lkcl: i'm going to clean the pictures of the SoM and add the marks |
| 18:11.14 | mnemoc | lkcl: my crappy camera made them a bit rounded, but they are sharp enough to be easy readable |
| 18:12.39 | mnemoc | uhm... more than a bit rounded |
| 18:32.09 | mnemoc | lkcl: is '1' the edge of the the short side or the edge of the long side? |
| 19:09.29 | lkcl | mnemoc: there's an arrow on the top of the SO-DIMM socket. right or wrong, i'm taking the pins _inside_ as "odd" meaning 1,3,5 |
| 19:09.43 | lkcl | and the pins on the _outside_ of the SO-DIMM socket as "even" |
| 19:09.58 | lkcl | so the arrow on left marks pin 1 |
| 19:10.27 | mnemoc | lkcl: i don't see any arrow... |
| 19:10.58 | lkcl | on the top of the white plastic of the SO-DIMM socket. look more closely. it's raised in the plastic. |
| 19:11.10 | lkcl | there is no "marked" arrow, it's in relief |
| 19:11.18 | mnemoc | lkcl: but anyway short or long side comes first? |
| 19:11.26 | lkcl | i don't know what you mean |
| 19:11.30 | lkcl | either by side |
| 19:11.33 | lkcl | nor by "first" |
| 19:11.39 | lkcl | nor what you're referring to |
| 19:11.42 | mnemoc | the socket has two parts |
| 19:11.52 | mnemoc | one with fewer pins than the other |
| 19:11.53 | lkcl | yes. |
| 19:11.54 | lkcl | no. |
| 19:12.07 | lkcl | there are exactly the same number of pins, top and bottom. |
| 19:12.24 | mnemoc | one has 20, the other 80... |
| 19:12.26 | lkcl | you mean the break? |
| 19:12.29 | mnemoc | yes |
| 19:12.30 | lkcl | right, ok. |
| 19:12.49 | lkcl | the part with 20 on a side is where you will see the arrow |
| 19:12.54 | lkcl | on the top |
| 19:13.16 | lkcl | that is the industry-standard sign for "start counting from 1 from here" |
| 19:13.18 | mnemoc | i'm looking at the picture, i closed the netbook long ago |
| 19:13.26 | mnemoc | and i still don't see the arrow |
| 19:13.27 | lkcl | ok. |
| 19:13.51 | lkcl | can you see the word "foxconn", upside down, which is in _inverse_ relief |
| 19:13.54 | mnemoc | but if the 1 is the first of the short block, i can count from there |
| 19:13.56 | lkcl | etched into the plastic |
| 19:14.27 | lkcl | it's on the _inner_ side. |
| 19:15.08 | lkcl | on the photo that jon took, IMG_3142.jpg, it's very very clear. just below the letter "n" of "foxconn". |
| 19:15.42 | lkcl | but - yes, the _inner_ side, first of the short block, we're designating "1" |
| 19:15.44 | mnemoc | don't keep making rounds, i only wanted to know from where to start counting as I do not see the arraw |
| 19:16.03 | lkcl | on the _outer_ side, designate even numbers, 2 to 200 |
| 19:16.08 | lkcl | inner side 1 to 199 |
| 19:16.26 | lkcl | so, inner side, first 20 pins, is 1 to 39. |
| 19:16.28 | lkcl | sorry |
| 19:16.35 | lkcl | outer side, first 20 pins, 2 to 40 |
| 19:16.53 | mnemoc | 1 .. 39 <break> 41 .. 199 |
| 19:16.56 | lkcl | check with the page |
| 19:17.05 | lkcl | http://elinux.org/index.php?title=CT-PC89E_SO-DIMM |
| 19:17.14 | lkcl | i've marked some of them as GND already |
| 19:17.32 | mnemoc | just confirm: 1 .. 39 <break> 41 .. 199 |
| 19:17.42 | lkcl | yep, that's it. |
| 19:17.57 | mnemoc | :) |
| 19:18.03 | lkcl | but double-check against the existing pins: the point is that i could have made a mistake |
| 19:18.25 | lkcl | get one of those pins wrong and we're fucked, it's $1000 down the toilet and we have to do another batch. |
| 19:18.49 | lkcl | i'd rather not do that :) |
| 19:19.21 | lkcl | ok - i'm going to stare at the PCB under the magnifying glass with a cloth over my right eye :) |
| 19:19.23 | lkcl | brb... |
| 19:19.29 | mnemoc | i'll make a picture including both sides |
| 19:19.49 | mnemoc | in layered format so you can play in your gimp |
| 19:20.05 | lkcl | star |
| 19:24.29 | lkcl | yaay, another pin. pin121 = DM9000 "chip select" |
| 19:24.30 | lkcl | yaay |
| 19:28.45 | lkcl | yaap, pin 115 = IOR#, 117 = IOW# |
| 19:55.13 | mnemoc | lkcl: look at http://geeks.cl/projects/chitech/ctpc89e-sodimm.png |
| 19:55.20 | mnemoc | (.xcf at the same location) |
| 19:56.17 | mnemoc | lkcl: I was thinking in writting 1/20 21/40 .... in the corresponding pin |
| 19:56.20 | lkcl | ta |
| 19:56.23 | mnemoc | aligned to those lines |
| 19:56.41 | mnemoc | unless you prefer another approach |
| 19:58.00 | lkcl | mnemoc, apologies for not making it clearer: by "SO-DIMM socket" i meant "SO-DIMM socket". as in "the SO-DIMM socket" |
| 19:58.09 | lkcl | as in "the SO-DIMM socket on the CT-PC89E motherboard" |
| 19:58.13 | lkcl | not "the SO-DIMM" |
| 19:58.17 | mnemoc | oh |
| 19:58.18 | mnemoc | ok |
| 19:58.21 | lkcl | there is no arrow on the SO-DIMM |
| 19:58.28 | lkcl | nor the word "foxconn" |
| 19:58.36 | lkcl | because it's on the SO-DIMM socket |
| 19:58.39 | mnemoc | ok, np |
| 19:58.47 | lkcl | which explains the confusion |
| 19:59.04 | mnemoc | btw, i think the ten soldering points in the upper right of my link is the JTAG |
| 19:59.13 | lkcl | but, it turns out that the SO-DIMM will be useful anyway |
| 19:59.23 | lkcl | but it's harder to identify things from that at the moment |
| 19:59.41 | lkcl | i'll need the SO-DIMM photos when i get the break-out boards, so it's not work wasted. |
| 20:00.10 | lkcl | also, actually marking the line down the "middle" of the pin itself (partially obscuring it) is clearer |
| 20:00.15 | mnemoc | i have a picture of the socket too |
| 20:00.34 | lkcl | because otherwise you wonder, "hmmm... is the red line indicating that pin 39 is to the left of the red line, or to the right?" |
| 20:00.48 | mnemoc | do you want me to finish numbering the module before I switch to the socket? |
| 20:00.56 | lkcl | if the line's actually _on_ the pin, there's no confusion |
| 20:01.02 | lkcl | the socket's more useful for now |
| 20:01.06 | mnemoc | ok |
| 20:01.28 | lkcl | we can get to the SO-DIMM later. |
| 20:01.48 | lkcl | doesn't want today to be a "3 pin" day :) |
| 20:02.16 | mnemoc | :) |
| 20:03.37 | mnemoc | now i do see the arrow |
| 20:03.54 | mnemoc | the inner side is odd, the outer even? |
| 20:04.01 | mnemoc | well... sure |
| 20:04.04 | mnemoc | the arraw |
| 20:04.06 | mnemoc | arrow |
| 20:04.09 | lkcl | okaay, let's see if i can get pins 22 and 20 on the right-hand PCI-e, they're supposed to be RESET and |
| 20:04.11 | lkcl | yes. |
| 20:04.18 | lkcl | inner is ODD because the arrow points to 1 |
| 20:04.32 | lkcl | that's the logic i made up, and i'm sticking to it :) |
| 20:04.38 | mnemoc | :) |
| 20:04.42 | lkcl | if it's wrong, it's consistently wrong and that's fine. |
| 20:04.51 | lkcl | a bit like electrons being -ve charged... :) |
| 20:04.58 | mnemoc | line from the middle of the pin, up |
| 20:05.14 | lkcl | yes. well, through the pad. through the middle of the pad. |
| 20:05.15 | mnemoc | one with line, four without, and so on |
| 20:05.20 | lkcl | yehhh |
| 20:05.25 | lkcl | missing the first 4. |
| 20:05.39 | mnemoc | ok |
| 20:05.46 | lkcl | so, 1,3,5,7,<mark9>,11,13,15,17,<mark19>.... |
| 20:05.57 | mnemoc | ok |
| 20:06.06 | lkcl | and if you want, do 2,4,6,8,<mark10>... on the top as well |
| 20:06.49 | lkcl | double-check with that SO-DIMM web page, to see if you have some GND pins correct, esp when you get half-way! |
| 20:06.59 | lkcl | complete pain to mis-count and have to undo beh |
| 20:16.39 | mnemoc | lkcl: look at http://geeks.cl/projects/chitech/ctpc89e-sodimm-socket.png and comment |
| 20:24.19 | lkcl | mnemoc: ah - good marking.... unfortunately very unclear photo! |
| 20:24.20 | lkcl | :) |
| 20:24.38 | lkcl | e.g on this: |
| 20:24.38 | lkcl | http://lkcl.net/arm_systems/CT-PC89E/photos/IMG_3142.jpg |
| 20:24.51 | lkcl | you can clearly make out the individual tracks |
| 20:24.54 | lkcl | ohh... wait.... |
| 20:25.02 | mnemoc | your camera is better than mine |
| 20:25.10 | lkcl | i have a proxy on which does image compression, gimme 1 sec... :) |
| 20:25.13 | mnemoc | and i assumed you were testing without the module |
| 20:26.45 | mnemoc | those pictures are the best i can get from my camera |
| 20:27.02 | lkcl | neeh, sadly it's not my camera |
| 20:27.08 | lkcl | yes, i'm testing without the module |
| 20:27.47 | lkcl | the photo of the SO-DIMM is very clear, though |
| 20:28.30 | mnemoc | ok, i'll take another of the socket |
| 20:29.06 | lkcl | you can make out the colours. |
| 20:29.08 | lkcl | hmmm |
| 20:29.22 | mnemoc | ? |
| 20:29.38 | lkcl | just wondering what's the best use of peoples' time, that's all |
| 20:30.08 | mnemoc | what do you mean by make out the colours? |
| 20:33.17 | mnemoc | i moved up the marking of the even part at http://geeks.cl/projects/chitech/ctpc89e-sodimm-socket.png |
| 20:33.57 | mnemoc | for taking another picture I need to wait for tomorrow, but having the marking style clear I can finish it tomorrow morning |
| 21:13.06 | lkcl | ack |
| 22:05.36 | lkcl | hooraay, i found one of the audio codec pins so i know where to start on those |
| 22:23.54 | *** join/#arm-netbook zecrazytux (~zecrazytu@78.40.125.105) |
| 22:33.16 | mnemoc | lkcl: awesome! :D |
| 22:42.38 | *** join/#arm-netbook zecrazytux (~zecrazytu@78.40.125.105) |
| 22:54.57 | lkcl | yep. got 5 more pins, and i think i've found the area for the SD card, but it is hard to tell |
| 22:55.08 | mnemoc | :D |
| 22:55.12 | lkcl | there's a batch of resistors, capacitors etc. in the way |
| 22:55.39 | lkcl | but it looks like pins 41,43, .... 49, 51 |
