**** BEGIN LOGGING AT Mon Dec 17 02:59:58 2012 Dec 17 10:01:38 hi Dec 17 18:14:19 aha, I love freenode. Guess a channel name, and it's right here. Dec 17 18:16:24 Anyway, I just acquired a GTA-01 and with a Debug board V2, kit appears complete *except* the FPC that goes between the debug board and the phone is missing. Dec 17 18:16:42 myself: oh Dec 17 18:16:51 myself: do you need it right now, right there? Dec 17 18:17:22 Not at all, I was just wondering if anyone knew the Mouser or Digikey part number for the FPC so I can throw it into my next parts order. Dec 17 18:18:45 I'd like to add that partnumber to the http://wiki.openmoko.org/wiki/Debug_Board_v2 page too, when it can be identified. Dec 17 18:20:06 myself: http://openmoko-public-mailinglists.1958.n2.nabble.com/Part-No-Of-FPC-Connector-on-debugboard-td3502543.html Dec 17 18:20:35 I feel strange talking to myself, heh Dec 17 18:21:39 myself: so it's rather likely it's "Hirose FH12-45S-0.5SH(55) (45 pins, pitch 0.5 mm)" Dec 17 18:22:40 Oh. That's the connector. But I see in the photos here: http://wiki.openmoko.org/wiki/Connecting_Neo1973_with_Debug_Board_v2 that the cable itself narrows and is not a plain cable.. Dec 17 18:23:43 I'll doublecheck the nooks and crannies in the box then, just to make sure it's not hidden in there somewhere. If it's really missing, I'll ask again here for help in figuring out how to obtain a replacement. Thanks. :) Dec 17 18:24:03 myself: good luck! Dec 17 18:24:53 myself: i do not think an FPC that doesn't narrow won't work :) Dec 17 18:25:31 Oh Dec 17 18:25:35 I see the other side now Dec 17 18:25:49 Meh, that cable really looks custom Dec 17 18:27:26 Well, it would seem sensible to me, to have used the same connector on both boards, and a straight cable between them. Surely there's a good reason it was done the present way, but it makes the cable less generic. Dec 17 18:28:03 I am puzzled about that decision too Dec 17 18:32:47 I'm encouraged by this notion, sidestepping the cable entirely: http://www.almesberger.net/misc/idbg/ Dec 17 18:33:12 myself: if you need only serial then do not bother at all, just solder to the uart testpoints. Dec 17 18:35:04 yeah, kinda thinking that. Or enlarge my collection of FPC breakouts and make an adaptoid. :) Dec 17 18:36:45 myself: you can get the cable from golden delicious or Pulster most probably. Dec 17 18:39:12 myself: i guess you already have an arm jtag adapter so probably you can "simply" use a straight fpc cable and a small adapter board. Dec 17 18:40:01 well, the debug board is such an adapter, so yes Dec 17 18:40:53 With luck nobody will break anything severely enough to require jtag recovery. Dec 17 18:41:13 I was just hoping, if it was a $2 cable from Mouser, to pick one up and toss it in the box just to be prepared. Dec 17 18:42:03 myself: just do not reflash uboot and you should be safe, yes. Dec 17 18:45:44 okay wtf: http://www.pulster.eu/index.html?d__ombdsm__OpenMoko_Bondage827.htm Dec 17 18:49:06 myself: lol Dec 17 22:13:25 hah! Dec 17 22:13:50 well, Goldelico should still have a few debubo-FPC Dec 17 22:14:25 while I wonder if I have *one* still Dec 17 22:15:53 if you don't need the gold plating on the ends, you can etch your own FPC. The base material is available, though not exactly inexpensive Dec 17 22:18:39 IIRC on debubo there's a 2.54mm dual row post connector in parallel to the FPC connector (probably not assembled). You could use a female post connector, usual flat cable, and etch a tiny connector board from thin PCB. solder that to other end of the flat ribbon cable to connect it to GTA01 Dec 17 22:42:49 well, you'll need to hack the debubo a tiny bit to replace FPC by post connectors: connect CN1-7 GSM_EN -> free pin J1-17; CN1-43 RXD -> free J11-6; CN1-44 TXD -> free J11-8 Dec 17 22:43:43 take care as this may render J1 and J11 non-conformant to any "usual" JTAG cables you might want to use with debubo. Dec 17 22:45:18 nNOR_WP (CN1-8) you may emulate on your mini-PCB on GTA01 end of FPC replacement: just add a dublication of the R70,R71 circuitry as found on debubo Dec 17 22:46:24 so you seem to get all needed signals on J1 + J11, to 'emulate' CN1 Dec 17 22:47:12 myself: ^^^ Dec 17 22:47:21 PaulFertser: ^^^ Dec 17 22:47:39 well, o/ **** ENDING LOGGING AT Tue Dec 18 02:59:58 2012
