  • [01:51:38] <xxiao> i'm syncing my rowboat repo, it may take a while, haven't done that for 2 months

  • [03:24:44] <Borillion> thank you so much
  • [03:24:52] <xxiao> i compiled it and it appears to be ok
  • [03:24:58] <Borillion> do you want to paste bin it?
  • [03:25:00] <xxiao> let me put somewhere you can download, you're welcome
  • [03:25:02] <xxiao> ok, wait

  • [03:25:59] <xxiao> http://pastebin.com/SMLWreyK
  • [03:26:14] <xxiao> it's super simple, it's just that it took me a while to sync my rowboat repo here
  • [03:26:20] <Borillion> its silly that the hardware manufacturer would make a 2 chip with the same device id's and reverse the x and y on the resistive one
  • [03:26:22] <xxiao> anyway try that, good luck
  • [03:27:34] <xxiao> is usb touchscreen as good as those non-usb ones
  • [03:27:51] <xxiao> those 4-wire ones assuming this is resistor-based
  • [03:28:56] <Borillion> Its not horrible, more responsive than I thought it was going to be
  • [03:29:13] <xxiao> how much is this thing
  • [03:29:33] <xxiao> a while ago someone i don't know asking me to get lcd7 working with rowboat on beaglebone
  • [03:29:56] <Borillion> usually the cheap android tablets that are resistive have a plastic sheet that sits above the touchscreen by as large as a 1/4 inch gap
  • [03:30:01] <xxiao> i did not have anything to test with then, not sure if that guy can use a usb-touchscreen
  • [03:30:16] <Borillion> and thats why they are awful
  • [03:30:32] <Borillion> it worked out of the box for me
  • [03:30:36] <Borillion> one sec let me get it
  • [03:31:11] <xxiao> the lcd7 is quite expensive, if your usb one works well and cheaper, i can reply that guy an email to suggest him try that
  • [03:31:23] <Borillion> xxiao, I have this http://www.amazon.com/Lilliput-669GL-70NP-T-HB-RV-Brightness-Screen/dp/B003H3B218
  • [03:31:23] <xxiao> i only know he is from boston...
  • [03:32:15] <Borillion> shockingly it has a 1920x1080 resolution
  • [03:32:19] <xxiao> is this the usb one which the patch refers to?
  • [03:32:40] <Borillion> the chip in it and its configuration is identical yes
  • [03:32:50] <xxiao> ic
  • [03:33:09] <Borillion> its not faytech brand tho, I bet one is the clone of the other :P
  • [03:33:22] <xxiao> i would expect a 'normal' 7" resistive lcd cost less than $30...
  • [03:33:44] <xxiao> considing those low-end tablet 7" can go as low as $50
  • [03:34:01] <xxiao> considering
  • [03:34:23] <xxiao> i was told you can buy 7" resistive android for $50-60 in south china now
  • [03:37:41] <Borillion> wow thats a good deal, I had a bad experience with those tablets lol

  • [14:34:16] <aholler> hope will die last
  • [14:34:26] <mru> so often that a second more or less matters?
  • [14:34:43] <koen> it needs to be ready within 10 seconds
  • [14:34:52] <mru> my usb-powered beagles stay on for months at a time
  • [14:34:53] <koen> anything below that is nice to have
  • [14:35:22] <mru> last reboot was caused by usb hub psu failing
  • [14:35:34] <mru> while I was in hong kong, naturally
  • [14:35:42] <koen> we're at 8s now, judging from tests that can drop down to 6s if we only start all the nodejs stuff ondemand
  • [14:36:02] <mru> starting stuff on demand is cheating
  • [14:37:11] <koen> you say that like cheating is a bad thing :)
  • [14:37:32] <mru> starting the service the first time it's needed won't make it actually usable any quicker
  • [14:37:43] <mru> in fact, it is likely to make it seem slower
  • [14:37:59] <mru> since the first request will have much higher latency that way
  • [14:38:16] <aholler> i was at 8s or such 2a ago on a 200mhz atmel armv4. and I cheated through displaying the a picture right from u-boot (1s) which was the same as fully booted ;)
  • [14:38:36] <mru> yes, that's a neat trick
  • [14:39:22] * guyzmo thinks about his android phone taking like 1 minute to boot
  • [14:39:44] <aholler> it depends all on what you want to start. things like usb and network need their time
  • [14:40:06] <mru> but until they are started, the system is not ready
  • [14:40:29] <mru> deferred service startup is just cheating by stopping the clock too soon
  • [14:40:42] <aholler> I rember scsi-times with 10-20s wait for settle at boot ;)

  • [14:42:11] <mru> no, he doesn't
  • [14:42:12] <koen> mru: heh, no
  • [14:42:29] <koen> guyzmo: ubuntu and linaro "experts"
  • [14:42:55] <guyzmo> heh, I was just kidding ;)
  • [14:43:18] <koen> gentoo supports cross builds just fine
  • [14:43:51] <mru> or so say the dozen or so dev boards on my desk
  • [14:44:00] <aholler> try no-keep-memory and reduce-memory-overhead, or try gold
  • [14:44:46] <koen> aholler: the next angstrom release will use gold, it's a lot better with memory and cpu
  • [14:44:52] <aholler> gentoo doesn't care much about cross, if it works it's just luck
  • [14:44:58] <koen> aholler: but this build is for the old release, still gnu ld
  • [14:45:12] <mru> aholler: then I must be having a huge amount of luck
  • [14:45:33] <mru> and I don't usually have any at all
  • [14:47:07] <aholler> anyway, all my arm-boxes are recompiling everything since 2 days with gcc 4.7 ;)
  • [14:47:42] <mru> make sure you turn off the auto-vectoriser with that
  • [14:48:07] <mru> I'm looking at some 10x slowdowns caused by it
  • [14:48:21] <lautriv> aholler, apropos compiling....i have here 3.4 booting and 3.5-rc1 freezing with identical config. did you alredy try 3.5 ?
  • [14:48:49] <mru> apparently they improved it in 4.7 so now it tries and fails on things it didn't attempt before
  • [14:49:05] <aholler> lautriv: no, 3.3 and 3.4 is no go here on omap. ehci doesn't work
  • [14:50:06] <mru> some of my beagles are still on 2.6.32
  • [14:50:15] <aholler> mru: i would't remark such slowdowns. the only thing I've took care off was the speed up in 3.3 (those fs-readahead thing)
  • [14:51:08] * lautriv would love to have a 2.6.32 but this target was left alone and then re-supported lately, reason for 3.5-rc1 which got a bunch of patches.

  • [16:22:06] * k4rtik (~k4rtik@122.179.93.147) Quit (Quit: leaving)
  • [16:22:31] <jet> I mean, I have a problem to program an arduino with a accelerometer through a i2c bus
  • [16:23:01] <jet> I wonder if I can use a beaglebone to do like an oscilloscope to understand what is going on, on the bus
  • [16:23:10] <jet> would it be fast enough?
  • [16:23:34] <guyzmo> jet - you can use GPIO pins to watch for binary inputs, or you can use the analog input (but you'll need to adapt the voltage)
  • [16:24:01] <jet> my bus is 3,3v
  • [16:24:19] <guyzmo> analog input runs at 1.8v
  • [16:24:42] <jet> ah??? i would need to adapt :-)
  • [16:24:45] <jet> but would it be fast enough for i2c? how fast can I read input?
  • [16:24:57] <guyzmo> I never tried the analog input, so I can't tell
  • [16:25:41] <guyzmo> ahah
  • [16:25:50] <guyzmo> from the official documentation : "Sample rate is 00K samples per second."

  • [16:26:21] <aholler> why analog, I think using the gpios just as a logic analyzer should enough. off course, seeing missing terminators would be really possible
  • [16:26:35] <aholler> s/would/wouldn't/
  • [16:26:36] <guyzmo> aholler - I agree
  • [16:26:47] <jet> since the unit is "K", I think it's probably not fast enough...
  • [16:27:12] <aholler> high speed i2c is 400kHz
  • [16:27:33] <aholler> not sure if a msp is able to do that
  • [16:27:37] <jet> so it's better to be at least 800k samples per second
  • [16:28:25] <aholler> just make it triggers when the level changes

  • [16:29:52] <guyzmo> jet - but if I were you I'd prefer using an external logic analyzer or oscilloscope
  • [16:30:12] <guyzmo> (you can even use arduinoscope)
  • [16:30:29] <jet> arduino is definitely not fast enough
  • [16:30:58] <guyzmo> well, aren't you talking to an arduino ?
  • [16:31:31] <jet> oscilloscope is a bit expensive, that's why I was thinking about beaglebone
  • [16:31:54] <jet> yes, my original problem is between an arduino and accelerometer
  • [16:32:00] <guyzmo> ah ok
  • [16:32:09] <guyzmo> so it's not the i2c bus you're trying to debug
  • [16:32:19] <jet> but arduino, is not fast enough to read with a regular input, a i2c bus
  • [16:33:07] <jet> my arduino is plugged to the accelerometer with a i2c bus
  • [16:33:10] <guyzmo> well, you'd better get some logic analyzer from seeedstudio (like the pirate bus)
  • [16:33:29] <guyzmo> they're cheap, work well and on linux
  • [16:34:53] <aholler> anyway, you already have something on the bone, it's i2c ;)
  • [16:35:24] <aholler> so if something doesn't work, look what happens, e.g. if the level changes at all
  • [16:40:09] <aholler> linux has bitbanged i2c too (i2c-gpio), that could help too

  • [16:48:35] <aholler> maybe someone wants to implement bitbanged i2c using js with cloud9 ;)
  • [16:50:12] <jet> what is bitbanged?
  • [16:52:01] <aholler> without hw-support, by just changing gpios and reading their level
  • [16:53:26] <aholler> you don't have to reach 100kHZ or 400kHz as the master dictates the clock, so you can use almost every hw for i2c
  • [16:53:50] <aholler> (if the hw is the master)
  • [16:53:57] <jet> I'm not sure gpios is fast enough??? It would need to read like 800k samples per seconds to do 400kHz
  • [16:54:24] <jet> ah, yes, we can slow down the bus...
  • [16:54:32] <aholler> you first have to get it to work at all, regardless how fast it is

  • [21:26:48] <zhivko> mru: what then?
  • [21:28:30] <dm8tbr> you took a random binary that was compiled for softfp and ran it in a hardfp userspace. that's highly likely to have undesired side-effects if it uses FP

  • [21:53:18] <zhivko> dmitbr: I tryy to crosscompile program in c++ with gnueabi crosscompiler - but it obviously doesn't put (ld-linux-armhf.so.3) for interpreter.
  • [21:53:39] <dm8tbr> then you are using the wrong cross compiler
  • [21:54:05] <zhivko> dm8tbr: so here is maybe the right question for you: how to define compiler option so it would set (ld-linux-armhf.so.3) for interpreter?
