2013-10-20 00:00 <wpwrak> about the hardest bit it correctly aligning the QFN chips. it's easy to overlook having them off by one pin. and of course, that wouldn't go so well.
2013-10-20 00:00 <eintopf> you need some components from (baumarkt) and drugstore, then you can build everything
2013-10-20 00:00 <eintopf> :)
2013-10-20 00:01 <eintopf> QFN http://www.finetech.de/uploads/pics/QFN_processcam_02.jpg
2013-10-20 00:01 <eintopf> something like this?
2013-10-20 00:02 <eintopf> easy....
2013-10-20 00:02 <wpwrak> yup. a lot of solder there, though
2013-10-20 00:02 <eintopf> you need (loetpaste)
2013-10-20 00:03 <eintopf> I have only a soldering iron from weller and solder
2013-10-20 00:04 <eintopf> and some lace in all colours
2013-10-20 00:04 <eintopf> i mean litz wire
2013-10-20 00:08 <eintopf> I think I have more success to build an anelok emulator than to build a real anelok ;)
2013-10-20 00:09 <wpwrak> you need flux, yes. SMT without flux is pretty much impossible.
2013-10-20 00:10 <eintopf> ah flux == loetpaste
2013-10-20 00:10 <eintopf> you mean SMD?
2013-10-20 00:14 <wpwrak> SMD and SMT and more or less synonymous
2013-10-20 00:14 <wpwrak> here's what the MCU looks like: http://downloads.qi-hardware.com/people/werner/anelok/tmp/solder-qfn.jpg
2013-10-20 00:14 <wpwrak> on the right side, i'm also guilty of using too much solder. ah well ...
2013-10-20 00:15 <eintopf> ah freescale
2013-10-20 00:15 <eintopf> wahhh
2013-10-20 00:15 <eintopf> on the front right
2013-10-20 00:15 <wpwrak> kineis kl25. nice little ARM.
2013-10-20 00:16 <eintopf> pin 2-3 from right
2013-10-20 00:16 <eintopf> are conntected
2013-10-20 00:16 <eintopf> maybe :)
2013-10-20 00:16 <eintopf> and in the middle of board
2013-10-20 00:16 <wpwrak> naw. that's just dirt
2013-10-20 00:16 <eintopf> ok
2013-10-20 00:17 <wpwrak> flux residues. they're hard to get rid of
2013-10-20 00:18 <eintopf> but you need flux
2013-10-20 00:18 <eintopf> and antiflux
2013-10-20 00:18 <eintopf> the little coppercolour wire
2013-10-20 00:18 <eintopf> to remove solder
2013-10-20 00:19 <eintopf> you use it but remove it not completely
2013-10-20 00:19 <eintopf> tricky, you need to have the right feeling for this
2013-10-20 00:19 <wpwrak> desoldering braid ? that only goes so far ... if you try too hard, you damage the traces
2013-10-20 00:20 <wpwrak> and yes, flux remover would help to go a bit further. but the ultrasonic cleaner already does a pretty good job.
2013-10-20 00:22 <eintopf> ah ultrasonic cleaner
2013-10-20 00:23 <eintopf> wpwrak: do you could make a layer of varnish on top of your prototype?
2013-10-20 00:23 <eintopf> my solution of all soldering a layer of glue
2013-10-20 00:25 <wpwrak> varnish would complicate rework
2013-10-20 00:25 <wpwrak> glue and soldering ? hmmm ...
2013-10-20 00:27 <eintopf> after soldering I take the hot glue gun
2013-10-20 00:27 <eintopf> and shot it on my board
2013-10-20 00:27 <wpwrak> why ?
2013-10-20 00:27 <eintopf> to prevent loose contact
2013-10-20 00:28 <wpwrak> what are you soldering ? water pipes ? :)
2013-10-20 00:29 <eintopf> no for example the lirc module
2013-10-20 00:29 <eintopf> next time I take a picture
2013-10-20 00:30 <eintopf> but then I would scare you
2013-10-20 00:30 <eintopf> :D

2013-10-20 00:34 <wpwrak> you mean the little grey squares in the middle ? they're solder paste

2013-10-20 16:40 <apelete> [    1.970000] couldn't find an available UDC
2013-10-20 16:41 <apelete> "missing bulk" message seems to come from ep_config_from_hw() which is called by musb_init_controller()
2013-10-20 16:42 <apelete> reading from musb_core.c code, couldn't see what's needed in order to get the usb endpoints config right
2013-10-20 16:43 <apelete> mth larsc: I added a j4740_musb_set_vbus() in glue layer but that didn't cut it, any idea ?
2013-10-20 17:06 bzb has quit [Remote host closed the connection]
2013-10-20 17:31 <DocScrutinizer05> set vbus is a tricky thing, since it depends on the particular device and how it implemented VBUS-boost and charging. Make DAMN SURE you switch off the charging before you enable vbus boost, or you might fry the hardware
2013-10-20 17:36 <DocScrutinizer05> you also don't want to enable 5V VBUS boost before you disabled any gadget driver that would try to start ENUM when detecting 5V on VBUS. Likewise you don't want to enable gadget mode (B) in musb_hdrc (after exit from hostmode A and thus disabling the booster) before any voltage buffered in capacitors on VBUS got discharged and voltage level is <2some Volt. Otherwise, see above
2013-10-20 17:38 <apelete> DocScrutinizer05: thanks for the warning, wasn't aware of that :). how am I supposed to swith off the charging on the nanonote ?
2013-10-20 17:38 <DocScrutinizer05> sorry, no idea
2013-10-20 17:39 <DocScrutinizer05> no schematics at hand
2013-10-20 17:40 <apelete> maybe I shouldn't be using the usb port to power the device (like I'm doing right now), and rely on the batteru instead until vbus setting is ok
2013-10-20 17:40 <apelete> s/batteru/battery
2013-10-20 17:40 <qi-bot> apelete meant: "maybe I shouldn't be using the usb port to power the device (like I'm doing right now), and rely on the battery instead until vbus setting is ok"
2013-10-20 17:47 <DocScrutinizer05> booster and charger powering concurrently doesn't hurt either of both.
2013-10-20 17:47 <DocScrutinizer05> powering VBUS
2013-10-20 17:48 <DocScrutinizer05> what does harm is booster and battery charging circuitry enabled concurrently
2013-10-20 17:49 <DocScrutinizer05> battery charging circuitry is always enabled, or gets started/enabled as soon as 5V on VBUS get detected
2013-10-20 17:49 <DocScrutinizer05> it doesn't matter if a external power source is connected to USB

2013-10-20 19:07 <mth> afaik the NanoNote doesn't support host mode; is VBUS ever driven by the device?
2013-10-20 19:12 dos1 has joined #qi-hardware
2013-10-20 19:43 <wpwrak> there's no host mode nor is there anything to drive VBUS

2013-10-20 20:04 <apelete> mth: does that mean the set_vbus() call shoud return without doing anything ?
2013-10-20 20:06 <mth> I don't know if it can be empty or should disable vbus in some register
2013-10-20 20:06 <apelete> I used the jz4770 set_vbus() function as an example for jz4740
2013-10-20 20:06 <mth> does the old UDC driver contain any hints?
2013-10-20 20:07 <mth> the 4770 does support both device and host mode, so it's different from the 4740
2013-10-20 20:11 <wpwrak> openshot turned out to be surprisingly usable. limited, but at least the basic things aren't so hard to figure out.

2013-10-20 20:23 <apelete> in 4770, vbus setting seems to be handled with :

2013-10-20 20:24 <apelete> I guess jz4740 only need the "else" part, or am I overlooking something here ?

2013-10-20 20:35 <apelete> been following on the mailing list, it baffles me how fast you're making this :-)
2013-10-20 20:43 <wpwrak> thanks ! :) it's actually not all that fast. alas, "real work" and the occasional social obligation get in the way ...
2013-10-20 20:52 <apelete> yeah well, since you're making both the hardware and software, it seems to be moving along pretty well if you ask me
2013-10-20 20:52 dandon has joined #qi-hardware
2013-10-20 20:56 <apelete> looking at the video posted earlier make me want to buy one of these already. I hope you'll be able to get it manufactured :)
2013-10-20 21:00 <wpwrak> hehe, so do i :)
2013-10-20 21:11 <mth> I'm not sure you have to set the mode at all, if the pdata already states it is host-only
2013-10-20 21:11 <mth> but it would be worth checking the musb code that reads the pdata
2013-10-20 21:12 <mth> sorry, device-only
2013-10-20 21:25 <apelete> mth: ok, will check what's in the pdata. any idea about that "musb-hdrc: missing bulk" ?
2013-10-20 21:25 <mth> endpoints for bulk transfers?
2013-10-20 21:26 <apelete> I guess so, but can't figure out where the usb endpoints are supposed to be configured
2013-10-20 21:27 <mth> /* Max EPs scanned. Driver will decide which EP can be used automatically. */
2013-10-20 21:27 <mth> 	.num_eps	= 6,
2013-10-20 21:27 <mth> (from struct musb_hdrc_config)
2013-10-20 21:28 <mth> so the musb core probably checks the hardware regs to figure out how many endpoints there are
2013-10-20 21:29 <apelete> so the number of ep found by usb core should match .num_eps in struct musb_hdrc_config ?
2013-10-20 21:46 <viric> grmbl there is no free codec for *interlaced* video. Neither theora or vp8 supports it.
2013-10-20 21:50 <apelete> mth: just tried ".num_eps = 4" in struct musb_hdrc_config since the old udc driver is advertising 4 endpoints
2013-10-20 21:50 <apelete> still getting "musb-hdrc: missing bulk" during boot though
2013-10-20 21:55 <mth> it says the number scanned, so the number found will be <= the number scanned
2013-10-20 21:56 <mth> adding logging to the scanning code would be useful
2013-10-20 21:56 <mth> to see if it is called, and if so, why it is rejecting endpoints
2013-10-20 21:57 <mth> is the hardware powered and its clock started before the scanning happens? (not sure if both are configurable, but most likely at least the clock is)
2013-10-20 22:05 <apelete> ok, will add logging to ep_config_from_hw() in musb_core.c to see what's happening exactly
2013-10-20 22:05 <apelete> thanks for the hint
