[18:56:09] <_koen_> eFfeM-away: no objections
[18:57:22] <sakoman> robtow: did you see my news on the zd1211 issue?
[18:57:50] <robtow> sakoman - I saw your notes in this channel yesterday!
[18:58:19] <sakoman> there was another this morning
[18:58:44] <ds2> sakoman: so it was a timing thing ?
[18:58:57] <robtow> I didn't see the one from this morning. What's new?
[18:59:09] <sakoman> disabling NetworkManager fixes the firmware download problem
[18:59:26] <robtow> Damn. Really?
[18:59:34] <robtow> Then it worked?
[18:59:36] <sakoman> try just renaming the NetworkManager init and rebooting
[18:59:50] <robtow> Ah.
[19:00:02] <ds2> that'd explain why it works for me in non Angstrom
[19:00:03] <robtow> Where is it?
[19:00:39] <sakoman> it is /etc/init.d/NetworkManager
[19:00:48] <sakoman> just rename it
[19:00:59] <robtow> Excellent. I'll try it.
[19:01:04] <robtow> MOST excellent.
[19:02:54] <_koen_> or just use update-rc.d NetworkManager remove
[19:03:01] <_koen_> that's what update-rc.d is for
[19:05:10] <robtow> Thanks _koen_
[19:05:34] <sakoman> _koen_: is there an easy way to undo a remove?
[19:09:48] * gdm_ (n=gdm@190.173.83.132) Quit (Read error: 110 (Connection timed out))
[19:10:28] <robtow> Hmmm. The SD card I built yesterday from the *29 demo image doesn't have a /etc/init.d/NetworkManager
[19:11:30] <robtow> i did update-rc.d NetworkManager remove
[19:11:32] <robtow> and rebooted.
[19:11:41] <robtow> unplugged the Shireen and plugged it back in
[19:12:14] <robtow> and am still getting the same zd1211 firmware error
[19:12:30] <sakoman> does your image have connman?
[19:12:51] <robtow> If it's in the 29 demo, yes. How can I check?
[19:12:51] <sakoman> if so, then you might want to disable it
[19:13:13] <sakoman> look in /etc/init.d and see if there is a connman init
[19:13:23] <robtow> yes, there is.
[19:13:27] <robtow> I'll disable it.
[19:14:32] <robtow> moved it out of the dir, rebooting.
[19:14:51] <adj> connman is evil. It always messes up my wired lan if I forget to kill it
[19:15:05] * bgamari (n=ben@64.252.153.54) has joined #beagle
[19:16:50] <adj> it has some kind of a twisted mind. Wired LAN usually works well for 5-10 minutes before connman decides that it's time to start generating glitches and disconnecting ethernet
[19:17:20] <robtow> Still got error -110 :-(
[19:18:39] <robtow> It appears to be trying to load two firmwares.
[19:18:54] <robtow> First zd1211b_up, then zd1211b_uphr.
[19:19:06] <robtow> It does not complain about up, just uphr
[19:19:26] <robtow> Wiat I said that wrong.
[19:20:52] <robtow> usb 1.2.1 requests, in order, ub, uphr, up, uphr - then says it can't load uph. And displays error -110.
[19:22:27] <robtow> wait!
[19:23:22] <sakoman> robtow: I don't know what to suggest. I was using my Gnome image and disabling NetworkManager allowed my zd1211 dongle to function
[19:23:41] <robtow> Sakmon - hold on, I'm trying something....

[22:09:22] <crashovrd> been seeing lots of talk about the zd1211
[22:09:33] <crashovrd> so thought i would pipe in
[22:09:54] <crashovrd> the zd1211 firmware is delay loaded until the device is first used
[22:10:02] <crashovrd> so when you load the module, you will see wlan0
[22:10:22] <crashovrd> as soon as you or NetworkManager try to use it, the firmware gets loaded
[22:10:43] <_av500_> djlewis: gm
[22:10:45] <crashovrd> which fails on the devices where the version mismatch occurs
[22:11:26] <crashovrd> i took the known working Fedora 12 source and diffed against the 2.6.32 omap source
[22:11:37] <djlewis> gm _av500_
[22:11:46] <crashovrd> the latter of which is more up to date
[22:11:56] <crashovrd> and could find no significate changes other than clean up
[22:12:28] <_av500_> djlewis: hows der robot?
[22:12:50] <crashovrd> the point that the device fails is right after it sends the initial code to it
[22:13:06] <crashovrd> after that it is locked and useless and any other comm attempts fail
[22:13:22] <crashovrd> even with extending timeouts, the problem persisted
[22:13:39] <_av500_> so what mismatches, the fw?
[22:13:46] <crashovrd> i have kernel premption disabled
[22:13:49] <robtow> crashovrd so what mismatches?
[22:13:59] <djlewis> _av500_: I been testing a new IR distance sensor. Sharp GP2Y0A02YK
[22:14:02] <crashovrd> but it seems like something else is going on during the transfer that creates the problem
[22:14:20] <crashovrd> robtow, the firmware version vs. the expected version in the silicon
[22:14:38] <robtow> crashovrd - I see.
[22:14:39] <crashovrd> it is a read only check that is done to make the determination
[22:14:39] <_av500_> cant the driver be made to load fw immediately?
[22:14:40] <crashovrd> no code is sent
[22:14:47] <robtow> Hmm.
[22:14:59] <robtow> So maybe I need an older version of the firmware?
[22:14:59] <crashovrd> in effect what happens is that certain devices have an extended boot sequence
[22:15:07] * _ANY_ (i=4f0cf60a@gateway/web/freenode/x-smipgnkgudciwzcs) has joined #beagle
[22:15:22] <crashovrd> robtow, i have elimiated firmware as the culprit by diffing it against known working on x86
[22:15:49] <crashovrd> my guess is that there is an IRQ or something happening during the upload to the device that hoses it
[22:15:58] <robtow> hmm
[22:16:11] <_av500_> cant the driver be made to load fw immediately?
[22:16:23] <ds2> why would you want to do that?
[22:17:00] <ds2> that would make things worse
[22:17:01] <crashovrd> _av500_, i am sure it can
[22:17:06] <crashovrd> but that would be a regression
[22:17:08] <_av500_> rulwe out that there is arace between fw upload and device use
[22:17:14] <crashovrd> they purposefull moved it to delay loading
[22:18:36] <robtow> koen built a 32 kernel image yesterday that he gave me that *did* load the firmware on 1st boot, but it hung with a soft lock on subsequent boots.
[22:18:38] <_av500_> well, it does not work :)
[22:19:15] <crashovrd> robtow, that is symptomatic of the problem
[22:19:22] <ds2> robtow: this is on the EHCI port, right? and this IS a modified C3 or a C4, right?
[22:19:25] <crashovrd> once the firmware load fails, the device is locked until powered off
[22:19:37] <robtow> ds2 - C4, stock.
[22:19:54] <crashovrd> so you would need to verify that the firmware loaded, and you got network transfer, and then it refused to reboot
[22:19:59] <ds2> robtow: but it is a EHCI port?
[22:21:13] <ds2> IOW, is it on the full size A connector or on the miniAB connector w/an adapter
[22:21:46] <crashovrd> my tests were conducted on a beagle C3 rev with the cap modfier
[22:21:54] <crashovrd> and on the EHCI port through a powered hub
[22:22:04] <robtow> EHCI, through powered hub
[22:22:30] <robtow> And the device is a two watt Shireen wifi module, which has a separate power cable.
[22:22:33] <crashovrd> in the past, i have connected the zd1211 directly to the EHCI and the failure was identical
[22:22:34] <ds2> trying to eliminate corrupt downloads
[22:22:59] <robtow> the separate power cable goes off to a wall adapter.
[22:26:56] <crashovrd> now that i think about, the only way to load the firmware from a file is after the system is up
[22:27:11] <crashovrd> because the FS needs to be mounted
[22:27:27] <robtow> crashovrd - yes.
[22:27:41] <robtow> Plugging the module in after complete boot results in the same failure.
[22:27:55] <crashovrd> otherwise you would have to embed it in the module and that would be licensing issue
[22:28:00] <crashovrd> because it would have to be GPL
[22:28:07] <djlewis> that used to be a fix ;)
[22:28:16] <djlewis> Plugging in after boot.
[22:28:21] <robtow> crashovrd - precisely!

[22:30:27] <robtow> crashovrd - you also have a need for zd1211?
[22:30:52] <crashovrd> yup. spent several days in the kernel code trying to find a work around
[22:31:50] <crashovrd> but i am by no means a kernel expert especially when it comes to how all the systems work together to get USB and firmware to work
[22:32:02] <crashovrd> i do notice that in other drivers there are mutexs
[22:32:09] <crashovrd> and not a single one in the zd1211
[22:32:27] <crashovrd> which also leads me to believe it may be some sort of concurrency issue

[22:33:46] <crashovrd> _av500_, it doesnt have to be. there are other parts and deals that could be made
[22:33:57] <crashovrd> its finding which is less of a hassle
[22:34:11] <djlewis> yesterday there was mention of many chipset variations in the zd1211 world, unsupported.
[22:35:11] <crashovrd> i think if i get time, i will just wrap the driver in a giant mutex and see what happens
[22:35:13] <crashovrd> :P
[22:35:16] <robtow> _av500_ - yes - I have a STRONG need to use a particular zd1211 module - as it has a 2 watt radio.

[23:34:39] <jav987> but c64 in ti is not listed as fpu but fixed point dsp
[23:34:46] <jav987> instead of floating point dsp
[23:35:04] <jav987> there was this other project that uses a different omap, and is also open source like this one
[23:35:16] <ds2> VFP
[23:35:26] <ds2> does NEON do FP to any level?
[23:35:46] <mru> NEON does single-precision FP

[23:36:47] <mru> it's more complicated
[23:37:11] <mru> the cortex-a8 has a neon+vfp unit
[23:37:36] <mru> it can do two single-precision FP ops per cycle
[23:37:36] <ds2> can NEON do any sort of MAC by itself?

[23:38:52] <ds2> yes
[23:38:59] <mru> yes, both integer and float
[23:39:10] <ds2> I know it can multiple but can it do that in a single instruction w/o bouncing back and forth with the ARM
[23:39:25] <ds2> in that case, I'd argue there is the DSP functionality there already :D
[23:39:34] <mru> it's a SIMD unit
[23:39:45] <mru> not quite what you normally call a dsp
[23:39:46] <jav987> mru, would you recollect a similar project like beagle board but using a bit different components? they gave one once here, but I can't find it in my bookmarks
[23:39:51] <ds2> I only know what Ian taught :D
[23:40:06] <mru> jav987: maybe the hawkboard
[23:40:14] <mru> that has an omap-l138
[23:40:24] <mru> which is arm9 + c674x
[23:40:34] <ds2> but it sounds like it has more then what the BF does and that claims to be a DSP hybrid

[23:40:49] <ds2> yes
[23:40:55] <mru> A8 is way more powerful
[23:40:58] <jav987> mru: that is probably the one. it does say floating point dsp
[23:41:10] <crashovrd> u got CPU, DSP, VFP, NEON, and GPU
[23:41:10] <mru> torusle: yes, but I'm not allowed to say much

[23:43:23] <mru> 6 different arm cores that I know of on it
[23:43:50] <mru> torusle: the omap3 iva2 block contains a c64x+ dsp core and a video accelerator
[23:44:01] <torusle> mru: jep, I know..
[23:44:03] <mru> the video unit is "behind" the dsp
[23:44:14] <mru> so only the dsp can talk to it
[23:44:24] <mru> on omap4 the video accel is directly on L3
[23:44:47] <mru> so you can drive it from the arm
[23:44:52] <torusle> ah, okay.. that may make a difference for the dsp-impaired :-)
[23:44:59] <jav987> the hawkboard contains a c674x
[23:45:11] <mru> torusle: it gives you a choice
[23:45:32] <mru> you might want to use the dsp for something else
[23:45:40] <mru> even if you're not "impaired"
[23:46:37] <mru> torusle: did you ever use any other compiler than gcc with blackfin?
[23:46:41] <jav987> mru: well, thank you for the info.

[23:47:38] <torusle> mru: I dont remember. I used the compiler that I got from AD.
[23:47:46] <mru> I'm wondering if the performance issues are down to gcc suckage
