  3. [00:01:24] <nerxgas> no
  4. [00:05:47] <mazzanet> hmm i'm having a curious issue

  11. [00:11:18] <nerxgas> can i factory reset my beagleboard?
  12. [00:12:44] <thurbad> hold on, I've got a boot script that may work
  13. [00:13:45] <thurbad> although it kinda looks like you've told it not to look for any boot scripts
  14. [00:15:05] <mazzanet> in newer versions of uboot you need 'mmc rescan' first
  15. [00:15:44] * Xerion_ (~xerion@5419A766.cm-5-2c.dynamic.ziggo.nl) has joined #beagle
  16. [00:15:49] <nerxgas> ..
  17. [00:16:01] <thurbad> yeah, I don't have the boot cmd portion at the moment
  18. [00:16:09] <mazzanet> before you can read anything
  19. [00:17:05] <mazzanet> nerxgas: reset and type this at the uboot prompt
  20. [00:17:14] <mazzanet> mmc rescan 0; fatload mmc 0:1 0x80300000 uImage; fatload mmc 0:1 0x81600000 uInitrd; bootm 0x80300000 0x81600000
  21. [00:17:54] * djlewis_ (~quassel@75.15.64.180) has joined #beagle
  22. [00:18:03] <nerxgas> Ramdisk image is corrupt or invalid
  23. [00:18:48] <mazzanet> bootm 0x80300000
  24. [00:19:01] <djlewis_> nerxgas: i meant the MLO version or Xloader version
  25. [00:19:07] <mazzanet> try that now
  26. [00:19:27] * buq2_ (~buq2@dsl-trebrasgw2-fe98de00-17.dhcp.inet.fi) has joined #beagle

  28. [00:19:59] <djlewis_> nerxgas: the one on the console, not on the file
  29. [00:20:01] <nerxgas> it said ramdisk image is corrupt or invalid
  30. [00:20:04] * pfoetche1 (~pfoetchen@winc043.informatik.uni-wuerzburg.de) has joined #beagle
  31. [00:20:16] <thurbad> you probably don't have a ramdisk
  32. [00:20:17] * javaJake_ (~javaJake@unaffiliated/javajake) has joined #beagle
  33. [00:20:26] <mazzanet> do you have a file on the sd called uInitrd
  34. [00:20:27] <mazzanet> ?
  35. [00:20:39] <thurbad> thats not usually partof angstrom
  36. [00:20:42] <nerxgas> no
  37. [00:21:12] <nerxgas> just MLO, u-boot.bin and uImage
  38. [00:21:14] <djlewis_> nerxgas: if you have a older xloader or MLO in nand it will not work with newer kernels
  39. [00:21:30] <mazzanet> angstrom doesn't have an initrd?
  40. [00:21:34] <mazzanet> curious
  41. [00:21:44] <nerxgas> how do i get a current version of xloader
  42. [00:21:50] <thurbad> yeah, but he's hosed his uboot environment on a c4
  43. [00:22:00] <djlewis_> nerxgas: what version is showing on the console

  54. [00:22:31] * Xerion_ is now known as Xerion
  55. [00:22:39] <djlewis_> thurbad: if he gets the beagboard.org prompt he has a bootloader
  56. [00:23:00] <djlewis_> nerxgas: U-boot ... what?
  57. [00:23:12] <thurbad> yes, he's getting throughto u-boot
  58. [00:23:24] <djlewis_> i think the 1.5 is late enough
  59. [00:23:31] <nerxgas> U-Boot 2011.06-dirty (Jul 19 2011 - 17:30:34)
  60. [00:23:40] <thurbad> but modified the bootcmd variable
  61. [00:24:43] <mazzanet> anyone got any ideas on my ehci issue?
  62. [00:24:50] * ds2 (noinf@netblock-66-245-251-24.dslextreme.com) has joined #beagle
  63. [00:26:08] <thurbad> does it give the same problem if you're not using the otg?
  64. [00:26:38] <nerxgas> i dont know
  65. [00:27:00] <thurbad> that one was for mazzanet
  66. [00:28:42] <djlewis_> nerxgas: revC4 or XM c4?
  67. [00:28:50] <nerxgas> revc4

  72. [00:30:14] <djlewis_> then just try to boot again
  73. [00:30:16] * jonpry (~jon@c-24-17-200-206.hsd1.wa.comcast.net) has joined #beagle
  74. [00:30:27] <nerxgas> i typed that in and it told me about correct usage
  75. [00:31:02] <nerxgas> oh nevermind
  76. [00:31:30] <nerxgas> looks like its doing stuff now
  77. [00:31:35] <jonpry> anyone ever notice bad things about the tps659x0 in audio slave mode? from what i can tell the oversampling pll cannot lock if your a few ppm from its idea of 48khz
  78. [00:32:26] <djlewis_> "stuff" sounds positive?
  79. [00:32:32] <nerxgas> that did it
  80. [00:32:43] <nerxgas> it booted up into gnome
  81. [00:32:47] <djlewis_> cool
  82. [00:32:52] <nerxgas> thanks
  83. [00:32:55] <djlewis_> u-bet
  84. [00:33:05] * jevin (~jevin@ec2-174-129-222-35.compute-1.amazonaws.com) has joined #beagle
  85. [00:34:34] <thurbad> last time I cleared nand was right before an sd pin broke off in my beagle.... while I know it's totally unrelated I haven't tried since :P
  86. [00:35:12] <djlewis_> thurbad: bummer
  87. [00:35:41] <thurbad> was less than a month old too
  88. [00:36:11] <djlewis_> thurbad: yeah, but when it gets to stinkin, ya gotta flush it :)
  89. [00:38:10] <djlewis_> mazzanet: did you mention which board ?
  90. [00:41:08] <mazzanet> thurbad: i have stuff conencted to both ports
  91. [00:41:09] <mazzanet> c4
  92. [00:45:15] <thurbad> anyone know which package has the bluetooth daemon, I installed bluez4 and it complained that the bluetooth init scrip twas missing
  93. [00:46:19] <djlewis_> mazzanet: again. erv or XM?
  94. [00:46:23] <djlewis_> rev
  95. [00:46:47] <mazzanet> revc4
  96. [00:47:11] * djlewis_ would hope the powers that be would have a more distinctive naming system
  97. [00:47:41] <djlewis_> mazzanet: oh, the model that is supposed to have the EHCI fixed ;)
  98. [00:48:27] <mazzanet> i'm probably pushing it's limits though
  99. [00:48:32] <djlewis_> mazzanet: what is connected to the port and all devices?
  100. [00:48:34] <mazzanet> i have a webcam on the host port
  101. [00:48:38] <mazzanet> and a powered hub on the otg port
  102. [00:48:40] <djlewis_> I was going there
  103. [00:48:45] <mazzanet> which has a 3g modem hanging off it
  104. [00:49:13] <mazzanet> ...and a gps
  105. [00:49:27] <mazzanet> ...and a wireless keyboard dongle
  106. [00:49:34] <thurbad> maybe you just flooded the port ~.~
  107. [00:49:42] <djlewis_> mazzanet: i am not certain any of the revxx series ever got ehci right
  108. [00:50:18] <mazzanet> it's fine up until about the 2 hr mark
  109. [00:51:42] <ds2> RevC's have EHCI just fine.
  110. [00:51:57] <ds2> RevA, RevB's have issues with signals
  111. [00:51:58] <djlewis_> mazzanet: of course it is. Then it's time for a break ;)
  112. [00:52:16] <djlewis_> ds2: bull
  113. [00:52:33] <ds2> djlewis_: it works for me
  114. [00:52:41] * djlewis_ goes and gets his boots on.
  115. [00:52:59] <ds2> Rev C2, C3 have performance issues for some units
  116. [00:54:03] <mazzanet> ds2: see my issue ^ ?
  117. [00:54:27] <djlewis_> ds2: load your revC with a couple of 640x480 streaminf webcams for a couple hours
  118. [00:55:00] <mazzanet> djlewis_: webcam only takes a snapshot every 2 mins
  119. [00:55:23] <ds2> djlewis_: I am convinced that is a software issue. I went throught that when I was doing the laser pointer thingie
  120. [00:55:28] <djlewis_> mazzanet: I dont expect the 3G is running constantly
  121. [00:55:30] <ds2> mazzanet: sorry, I missed it
  122. [00:55:34] <mazzanet> 3g is
  123. [00:55:49] <djlewis_> sounds expensive
  124. [00:55:49] <mazzanet> ds2: after roughly 2 hrs i get ehci-omap force halt
  125. [00:55:57] <mazzanet> ds2: and lose both ports
  126. [00:56:01] <ds2> mazzanet: what kind of device?
  127. [00:56:09] <djlewis_> listed above
  128. [00:56:36] <mazzanet> ds2: webcam on host port, powered hub with 3g modem, gps and wireless keyboard receiver on the otg port
  129. [00:56:38] <ds2> my backscroll doesn't go very far. got disconnected
  130. [00:56:48] <djlewis_> sorry
  131. [00:56:59] <mazzanet> djlewis_: quota charged not time
  132. [00:57:25] <ds2> I suspect a problem with handling ISOC ep's more then an actual hw problem
  133. [00:57:34] <ds2> ISOC in general is a mess
  134. [00:58:03] <mazzanet> isoc?
  135. [00:58:10] <ds2> Isochronous
  136. [00:58:19] <ds2> what's used for multimedia devices
  137. [00:58:21] <djlewis_> well, our beagleboard world is intended for developers and hobbyists, not prime time ;)
  138. [00:58:25] * Ceriand|desktop (~Ceriand@unaffiliated/ceriand) has joined #beagle
  139. [00:58:51] <ds2> if you loose both ports, that is almost most certainly not the hw
  140. [00:59:02] <ds2> the 2 parts are completely unrelated
  141. [00:59:23] <ds2> there are 3 USB controllers on the OMAP3530 - EHCI, OHCI (I think), and MUSB
  142. [00:59:45] <ds2> EHCI is what is on the host port, MUSB is what is on the OTG port. OHCI is not brought out
  143. [01:00:05] <ds2> djlewis: there are production devices using the same parts
  144. [01:01:03] <mazzanet> ehci-omap ehci-omap.0: force halt; handshake fa064814 00004000 00000000 -> -110
  145. [01:01:04] <djlewis_> ds2: certainly, but most likely custom software
  146. [01:01:24] <ds2> djlewis: which is my point... it is a SW issue not a problem with the classic boards
  147. [01:01:41] * djlewis_ is not convinced
  148. [01:01:44] <ds2> the xM's use diff silicon so it isn't a simple comparism
  149. [01:02:00] <mazzanet> scrap my time comment
  150. [01:02:14] <djlewis_> mazzanet: how so?
  151. [01:02:36] <djlewis_> two hours or qouta, not time
  152. [01:02:41] <mazzanet> i've got... 45 mins, 2.5 hrs, 1.5 hrs
  153. [01:02:53] <mazzanet> two hours*
  154. [01:02:53] <djlewis_> before failure . .
  155. [01:02:56] <mazzanet> yeah
  156. [01:02:58] <ds2> if you are loosing both ports, it is something higher up that is breaking
  157. [01:03:57] <djlewis_> ds2: show me a commercial product that utilizes so much usb of the omap
  158. [01:04:34] <ds2> djlewis: define 'so much'
  159. [01:05:28] <ds2> YES. 3G dongle is HS
  160. [01:06:33] <ds2> not sure if anyone has used all 3 but using 2 definitely has happened.
  161. [01:07:07] * scrp3l (~scrp3l@201.250.187.157) Quit (Quit: Ex-Chat)
  162. [01:07:16] <mazzanet> i'm only doing it this way because the webcam seems to need it's own port
  163. [01:07:28] <mazzanet> otherwise i get bandwidth errors
  164. [01:07:48] <ds2> that sounds like a SW issue in how it manages microframes on a HS port
  165. [01:14:11] <mazzanet> actually scratch all that
  166. [01:14:30] <mazzanet> i don't think i'm losing musb
  167. [01:14:48] <ds2> =)
  168. [01:15:01] <mazzanet> as i still have 3g
  169. [01:15:20] <ds2> what kernel, btw?
  170. [01:15:43] <mazzanet> 2.6.35

  232. [04:51:53] <julumme> hi,
  233. [04:52:25] <julumme> I wonder if someone could help me out on some native compiling questions on BB
  234. [04:53:19] <julumme> I'm running Robert Nelson's Ubuntu image currently, and everything seems to work more or less
  235. [04:53:54] <julumme> I am however a bit new to the whole development on arm, and don't yet understand some fundametal stuff
  236. [04:54:13] * prpplague (~prpplague@ppp-70-249-157-222.dsl.rcsntx.swbell.net) Quit (Quit: Leaving)
  237. [04:54:54] <julumme> my goal is to use serial infra transceiver on the beagle, but for that it looks like I would need to recompile the lirc modules
  238. [04:55:16] <julumme> currently I have them installed, but dpkg-reconfigure complains that I don't have kernel sources to compile against
  239. [04:55:40] <julumme> I wonder what would be a suggestion from someone who knows about this stuff what should I do
  240. [04:55:58] <julumme> first of all, I don't have any kernel sources downloaded, nor do I have any tools on the Beagle to compile natively anything
  241. [04:56:00] <dm8tbr> as you are using ubuntu: ask on #ubuntu-arm
  242. [04:56:10] <julumme> oh, interesting
  243. [04:57:24] <dm8tbr> even #ubuntu, as you have a generic problem that's architecture independent
  244. [04:58:04] <julumme> thanks for your advice, I'll see what folks might suggest on those channels
  245. [04:58:20] <dm8tbr> np
  246. [04:58:49] <dm8tbr> oh and before I forget: huomenta
  247. [04:59:13] <julumme> wait, how do you know
  248. [04:59:38] <julumme> you deducted from my name, or ? :)
  249. [05:01:05] <dm8tbr> yes
  250. [05:01:30] <julumme> right - well, huomenta huomenta, even though it's already 2pm where I reside ;)
  251. [05:01:32] <dm8tbr> besides I live in herwood forrest. ;)
  252. [05:01:39] <dm8tbr> hehe
  253. [05:02:48] <dm8tbr> (that's hervanta, tampere)
  254. [05:06:03] <julumme> right
  255. [05:06:06] <julumme> :)
  256. [05:06:52] <julumme> I'm originally from Oulu, so I assumed herwood was somewhere in UK ;)
  257. [05:07:01] <julumme> didn't bother googling
  258. [05:09:12] <dm8tbr> the whole herwood thing is mostly only known to TTY students/alumni I guess

  323. [12:12:50] <speakman> So - to day - what kernel is most full-featured and stable for OMAP 35xx currently?
  324. [12:13:46] <koen> the angstrom 2.6.32 kernel
  325. [12:13:57] <koen> but the 3.0.3 angstrom kernel is shaping up as well
  326. [12:13:59] <speakman> angstrom kernel? do they make their own?
  327. [12:14:21] <speakman> (I'm not using Angstrom, but compile my kernel from scratch)
  328. [12:15:00] <thurbad> you can make your own kernel and still use angstrom, but they provide a default kernel
  329. [12:15:26] <speakman> yes, but which kernel is the ??ngstr??m kernel based upon?
  330. [12:15:43] <av500> linux
  331. [12:15:58] <speakman> no really? me too. what an coincident :)
  332. [12:16:01] <thurbad> 2.6.32 was based on omap-psp I believe
  333. [12:16:05] <speakman> oki
  334. [12:16:22] <thurbad> 3 maybe mainline, dunno
  335. [12:16:49] <speakman> Is there lots of stuff in psp which is lacking in official 3?
  336. [12:17:26] <av500> some dsp/isp stuff I guess
  337. [12:25:17] <speakman> ...and why isn't it merged into mainline? :)
  338. [12:25:40] <av500> go on an merge it

  387. [15:21:35] <filippogiuliani> i've the same problem of yesterday, i can't use the UARTs on my beagle board xM
  388. [15:23:09] <filippogiuliani> i tried to rebuild the u-boot paying attention on setting the mux for the UARTs and i think it's right..
  389. [15:25:45] <filippogiuliani> there ins't any configuration for serial port I forgot during the installation of ubuntu?
  390. [15:27:36] <thurbad> did you follow any instructions for setting up the uart?
  391. [15:29:38] <thurbad> also which serial port are you trying to enable?
  392. [15:31:12] <filippogiuliani> i was unable to find any instructions on web.. i tried all four UARTs but i need just two ports..
  393. [15:32:33] <[IDC]Dragon__> av500: pong
  394. [15:32:47] <[IDC]Dragon__> but mostly afk

  397. [15:34:01] <thurbad> there's instructions for uart2 here: http://elinux.org/BeagleBoardPinMux#UART2_enabling_within_U-boot
  398. [15:35:12] <thurbad> that one's a little tricky

  406. [15:43:11] <thurbad> we're using ttyS0 on our board and we didn't have to mess with a second set of muxes
  407. [15:44:49] <Adi_> hello .. have anyone also encontered sudden disconnections while working with the ethernet / USB? ..... with the BB xM?
  408. [15:46:43] <Adi_> problem with the smsc95xx driver with this error: "hub 1-0:1.0: port 2 disabled by hub (EMI?)"
  409. [15:48:17] <thurbad> hmm, does the usb still work after that, or is it just the ethernet portion?
  410. [15:48:52] <Adi_> the usb also goes down
  411. [15:49:36] <Adi_> dmesg says:
  412. [15:50:08] <Adi_> hub 1-0:1.0: port 2 disabled by hub (EMI?), re- enabling ...

  417. [15:50:44] <thurbad> use pastebin when it's more than a line or two
  418. [15:50:57] <Adi_> yep, sorry for that
  419. [15:51:24] <filippogiuliani> maybe could it be because I install the kernel that the guide i followed had suggest me? (http://elinux.org/BeagleBoardUbuntu#Install_Latest_Kernel_Image)
  420. [15:51:44] <thurbad> no worries,I'm not the net police especially during slow periods, but some people still get annoyed

  424. [15:54:49] <thurbad> is it unregistering the driver? that's kind of what it looks like

  437. [15:58:59] <thurbad> ah, so it's up higher in the usb driver stack than the smsc component?
  438. [15:59:21] <av500> maybe
  439. [15:59:26] <NotTooDumb3> av500, Hi..are the synch values dependent on display x and y resolutions? is display data sheet, the only way, to know synch values? thank you.
  440. [16:00:14] <NotTooDumb3> and if we take case of TV, for NTSC, PAL standards the synch values standard irrespective of the display device's size?
  441. [16:00:15] <av500> you can also guess them
  442. [16:00:23] <Adi_> thurbad: i don't know...
  443. [16:00:34] <NotTooDumb3> guess? may never work..
  444. [16:00:37] <av500> as you said, PAL and NTSC are "standards", no guessing needed
  445. [16:00:45] <Adi_> i thought maybe it's a known issue
  446. [16:02:06] <NotTooDumb3> av500, with my omapfb driver for TV, i am going to NTSC mode, but not seeing Angstrom logo, i am using angstrom file system..any suggestions about what i would have missed configuring?

  508.

  588. [18:48:36] <Crofton> what are you doing with them?
  589. [18:49:00] <vielster> I have several 16-bit devices attached, and they work great
  590. [18:49:22] <vielster> but I have an 8-bit SRAM attached and cannot seem to address the device down to single byte resolution

  593. [18:49:44] <Crofton> harder than I can answer
  594. [18:49:45] <vielster> I assumed BE0 would allow me to address odd/even bytes

  596. [18:50:07] <Crofton> there is something funny about that case
  597. [18:50:18] <vielster> but BE0 doesn't do anything when I make accesses to the device
  598. [18:51:41] <prpplague> vielster: unless the sram has a 8-bit A/D latch configuration, you can't get 8-bit accuracy
  599. [18:52:06] <prpplague> (or at least i know a way)
  600. [18:52:25] <vielster> so the byte enables don't work as they should?
  601. [18:52:27] <prpplague> vielster: what sram device are you using?
  602. [18:52:57] <vielster> It's a Dallas NVSRAM
  603. [18:53:15] <vielster> (battery backed SRAM module for non volatile storage)
  604. [18:53:17] <prpplague> ok that doesn't tell me a thing
  605. [18:53:44] <prpplague> vielster: what is the part number?
  606. [18:53:45] <vielster> has a standard 8-bit Assync interface (not address/data latched)

  611. [18:59:51] * prpplague is always amazed at what people try to interface to SoC's without understanding what the interface was designed for
  612. [19:01:55] <vielster> I've connected similar devices to PPC processors, which don't give you A0 or A1, so you have to use the BE (Byte Enable) to address to the byte level
  613. [19:02:51] <vielster> In most bus architectures, if you do an explicit 8-bit read/write, the byte enable signals will allow addressing a finer resolution than the bus width

  617. [19:05:26] <prpplague> vielster: the GPMC on omap3/4 simply wasn't designed to work with 8-bit interfaces
  618. [19:07:03] <vielster> ADDR BE1 BE0
  619. [19:07:40] <vielster> the TRM is not terribly explicit in this regard
  620. [19:07:53] <prpplague> vielster: that would be as if you had two 16-bit devices

  633. [19:12:31] <mru> job done
  634. [19:13:02] <vielster_> the issue is that the code was written to be generic, but assumed contiguous memory
  635. [19:13:28] <vielster_> i guess to be more specific, contiguous, non-aliased memory
  636. [19:13:31] <mru> it is contiguous, just not in the usual way
  637. [19:14:20] <vielster_> there were memory mapped data structures and such
  638. [19:14:31] <prpplague> vielster_: i assume you;ve created a gpmc glue driver, correct?

  663. [19:34:50] <vielster_> I don't know why working outside of the linux kernel is a waste of time...
  664. [19:35:33] <vielster_> our application requires a 200ms boot time and true real time scheduling, so the linux kernel is out
  665. [19:35:46] <jonpry> BE0 would not provide an additional address bit because its only ever driven for even addresses
  666. [19:36:26] <vielster_> and for odd accesses, it would not be driven

  693. [19:59:58] <_av500_> npothing special to boot from SD with an XM
  694. [20:00:19] <_av500_> and demo images should come up with 1280x1024 in dvi

  696. [20:01:30] <cryptision> The Beagleboard seems really cool. I just don't get why the designers insist on using a serial cable. I can see needing if you don't have an compitable monitor. Id like to see an image were someone could get tty over usb or with ssh over eth0. that would be cool. As soon as I get a serial cable, I'll try and code an beagle linux distro for just this sort of situation.
  697. [20:01:50] <_av500_> sure
  698. [20:01:56] <_av500_> you dont need the serial at all
  699. [20:02:04] <_av500_> it just helps

  702. [20:03:05] <_av500_> no idea
  703. [20:03:16] <_av500_> watching the serial logs at boot would help :)
  704. [20:03:27] <_av500_> can be as simple as sdcard not pushed all the way in

  719. [20:16:00] <jamuraa> gst-dsp should work on 3.0+ kernels with the XM rev A? or should I downgrade to the 2.6.xx as listed on the page?
  720. [20:16:55] <_av500_> depends on what dspbridge driver 3.0 has
  721. [20:17:05] <_av500_> maybe they have stopped rewriting it all the time
  722. [20:17:23] <_av500_> but I guess they pretty much stopped working on it
  723. [20:17:56] <_av500_> since nokla is more after directshow these days....
  724. [20:22:35] <cryptision> lol, djlewis at least we don't have to code the beagleboard in COBALT :)
  725. [20:23:06] <_av500_> lol COBALT :)
  726. [20:23:51] <cryptision> For the moment the only feed back on the Beagleboard I get are the green led. The power led comes on then the two sd card led and after that an led near the usb ports. all will go out and the process is repeat. What does that usually mean?
  727. [20:24:07] <_av500_> no idea
  728. [20:25:05] <cryptision> I would imagin that on a normally booted beagleboard, the sd card lights would act similar to a drive activity light. Would that assumption be correct?
  729. [20:25:12] <jamuraa> hard to tell without serial.
  730. [20:25:38] <jamuraa> one of the "sd card lights" is a hdd activity (but inactive on), the other is a heartbeat after boot

  749. [20:37:01] <ds2> if you look carefully, Motorola for some phones had a >1A wall wart with a mini USB connector on it. Good luck finding it
  750. [20:37:02] <cryptision> for right now, I have eth and hdmi connected
  751. [20:37:33] <ds2> if you are careful with modifying the SW, you might be able to get it to co-exists with 500mA
  752. [20:37:43] <_av500_> ds2: motorola married a search company in order to make finding chargers easier
  753. [20:38:09] <cryptision> I rather have enough juice,but I don't want to much juice what would the maximum amount of amperage would the BB take?
  754. [20:38:19] <thurbad> get a good 2000 or 2500mA 5V supply
  755. [20:38:28] <ds2> with those traces, probally 10-20A
  756. [20:38:32] <_av500_> you cannot have too much juice
  757. [20:38:41] <jacekowski> i have 10A
  758. [20:38:46] <cryptision> 10-20a! wow, thats a lot of juice
  759. [20:38:53] <ds2> you said max.
  760. [20:39:05] <_av500_> thats like saying you cannot drink from a lake since it has too much water

  807. [22:36:42] <vielster> if I have a 16-bit SRAM connected, and I want to store a single byte, the BEx signals should represent which byte needs to be written
  808. [22:37:31] <vielster> for instance, if I had two parallel 8-bit SRAM devices, it could be gated with the individual chips write enable or even their chip select

  812. [22:38:26] <vielster> and fast
  813. [22:38:31] * lyakh (~lyakh@dslb-178-009-253-082.pools.arcor-ip.net) Quit (Quit: thanks, bye)
  814. [22:39:10] <ds2> how fast?
  815. [22:39:34] <mru> don't they make small nvrams on i2c and such?
  816. [22:39:41] <ds2> there are less painful ways via a serial bus
  817. [22:39:43] <ds2> heh
  818. [22:39:44] <vielster> yes, but I2C is far too slow
  819. [22:39:48] <mru> spi then
  820. [22:39:55] <ds2> how fast do you need it?
  821. [22:40:11] <ds2> need i.e. are you doing self modifying code and need it to keep up at 1GHz
  822. [22:40:14] <mru> not all that fast if 8-bit is enough
  823. [22:41:02] <vielster> Likely at around 300KB/s (big B)
  824. [22:41:23] <ds2> so 3000Mbs sec
  825. [22:41:29] <ds2> an SPI bus can do up to 48MHz
  826. [22:41:43] <ds2> bah... I mean 3Mbs
  827. [22:41:45] <vielster> that is true, but the SPI bus incurs a lot of overhead in setting up transfers
  828. [22:41:47] * djlewis (~djelwis@adsl-65-64-30-13.dsl.ltrkar.swbell.net) Quit (Quit: Leaving.)
  829. [22:42:03] <ds2> yes but at 48MHz, you are 10x faster then you are requiring
  830. [22:42:23] <vielster> that's assuming you can simply stream data at 48Mbit
  831. [22:42:35] <vielster> we're currently using SPI for other data as well
  832. [22:42:39] <vielster> (CAN)
  833. [22:43:11] <ds2> why stream it? you can't even consume it that fast
  834. [22:45:13] <vielster> high bandwidth usage on SPI is pretty inefficient on the OMAP
  835. [22:45:29] <vielster> unless you can break it into very large chunks
  836. [22:46:00] <ds2> then... :D
  837. [22:46:51] <vielster> from my experience...because the register set is in L3 or L4 region (can't remember off hand), each read/write access is pretty slow
  838. [22:47:19] <vielster> so, setting up the DMA and SPI incur quite a bit of overhead
  839. [22:49:22] <vielster> plus we have other devices on the bus...I think that's actually the more delimiting factor...we're using SPI1 and SPI3 already for other I/O devices
  840. [22:50:59] * kaio (~kaio@fedora/kaio) Quit (Ping timeout: 245 seconds)
  841. [22:51:11] <vielster> and the thought was that the GPMC is available and fast, so use it
  842. [22:51:24] <vielster> but it's not behaving as we thought it would
  843. [22:54:21] <vielster> so the thought was just to replace the 8-bit NVSRAM with a 16-bit NVSRAM on the next spin, but I'm not sure that it will solve the issue because the byte enables will be required to make writes function properly
  844. [22:57:31] <vielster> ds2: do you not agree with using the fastest interface available for accomplishing a task?
  845. [23:00:27] * siegen (~lechaguin@sign-4db60eac.pool.mediaWays.net) has joined #beagle
  846. [23:01:00] <mru> use the simplest interface that is fast enough
  847. [23:03:22] <vielster> okay...gpmc would accomplish that no?
  848. [23:03:40] <vielster> it's an extension of RAM
  849. [23:04:46] * marcompile (~marco@20158006164.user.veloxzone.com.br) Quit (Quit: Ex-Chat)
  850. [23:05:32] <vielster> mru: there is no protocol required to write to NVRAM through GPMC. Through I2C/SPI you are required to write some handler that takes care of different commands/states/etc
  851. [23:06:00] <ds2> the complexities of the GPMC needs to be carefully weighed
  852. [23:06:09] <ds2> and what you described suggests it is non optimal
  853. [23:06:51] <ds2> you are still looking at breaking out a lot of traces (24-30 traces)
  854. [23:07:07] <ds2> and then you have potential EMI issues
  855. [23:07:17] <ds2> it just ain't worth the trouble for such a slow datarate
  856. [23:08:45] <siegen> hi! how can i pass to a GPtimer interrupt handler the reference to an i2c-client
  857. [23:08:46] <siegen> ??
  858. [23:11:47] <ds2> generally, pointers are used.
  859. [23:12:10] <siegen> i have an timer interrupt using dmtimer library which calls a interrupt handler every 10 ms , inside of this handler i would like to read my i2c_client

  861. [23:18:33] <jonpry> i'm not sure that its possible to use the i2c hardware from an interrupt context
  862. [23:20:24] <siegen> not
  863. [23:20:31] <siegen> is not possible
  864. [23:21:02] <siegen> but we can read i2c in the bottom half using workqueues
  865. [23:21:25] <siegen> the only way for functions which can sleep
  866. [23:22:44] <siegen> i need to pass the reference to my i2c-client because in the interrupt hanlder i will queue the work to do it
  867. [23:24:31] <siegen> my real problem is that i need to read some i2c sensors at accurate periodically time (i.e 10 ms) and in userspace app i dont get accurate time due to latencies i guess
  868. [23:24:43] <siegen> so i am moving the code to kernel space
  869. [23:25:19] <siegen> using timer interrupt and trying to read in bottom half of the interrupt handler

  878. [23:56:59] <housel> annoying that beagleboard.conf lists apm in MACHINE_FEATURES but the defconfig doesn't have APM emulation turned on
  879. [23:57:31] <mru> why would you need that?
  880. [23:57:52] <mru> apm was a rather primitive interface in 90s pc bioses
  881. [23:58:17] <housel> I don't, so it shouldn't be in MACHINE_FEATURES
