[03:57:56] <Dan211> hi there, has anyone had problems with the BeagleBone transmitting serial data at > 115.2k baud?
[03:58:21] <Dan211> It seems to receive OK at higher speeds (500k) but not transmit.
[03:58:43] <Dan211> I have scoped the signal and it seems to be OK, however it cannot be successfully read by my PC
[04:01:26] * Russ (foobar@ip68-106-254-4.ph.ph.cox.net) has joined #beagle
[04:04:40] <jay6981> never seen a uart run at more than 115k
[04:05:32] <aholler_> some usb-dongles are able to do more
[04:05:38] * aholler_ is now known as aholler
[04:06:03] <jay6981> serial is 12v right? lots of reflection afaik
[04:08:06] * dm8tbr regularly uses OMAP3 with 1MBaud
[04:08:28] <mdp> jay6981, you're thinking of rs-232 most likely at that level
[04:08:41] <mdp> serial doesn't mean rs-232
[04:08:57] <jay6981> usb dongles are rs-232 right?
[04:09:25] <mdp> only at the DTE end
[04:09:46] <aholler> Dan211: are you sure the pc-side is able to do more?
[04:09:57] <jay6981> he said he was talking to a PC so I figured 232

[04:10:26] <mdp> for example, beaglebone uarts are 3.3v i/o???
[04:10:56] <mdp> jay6981: hrm, most pcs don't have rs-232 ports now though
[04:11:22] <dm8tbr> the problem beyond 115k2 is that some chipsets don't cope well with them
[04:11:25] <Russ> 12v to -12v is a "typical" voltage swing for rs232
[04:11:36] <Russ> but it could be different depending on hardware
[04:11:37] <mdp> with beaglebone's ftdi???the serial comm never is translated into rs-232 for transmission to the pc
[04:11:38] <jay6981> hm, TIL
[04:11:54] <mdp> Russ, up to +-15V per spec, in fact, iirc
[04:12:15] <aholler> hmm, the ftdi should be able to do more
[04:12:21] <dm8tbr> e.g. pl2303 won't do 500 and 1000k but something 'close' to that
[04:12:42] <aholler> I had forgotten the bone has an ftdi on board
[04:12:53] <dm8tbr> usb2serial ftdi I have regularly used with 1MBaud

[04:29:21] <Dan211> hey guys sorry for the slow reply. Some additional information - I am trying to communicate between an Arduino and BeagleBone using serial. I am able to send data Arduino -> Beagle at 500kbps but unable to go above 115.2k the other way. If I connect tx to rx on the Arduino, it can handle 500kbps, likewise with the Beagle but not when connected together. I am doing some level conversion to account for 3.3V <-> 5V
[04:30:11] <Dan211> 5V -> 3.3V uses a voltage divider, 3.3V to 5V uses a transistor but should work without (and does at <= 115.2k)
[04:30:55] * harshpb (~harsh@122.167.99.242) Quit (Read error: Connection reset by peer)
[04:31:09] <aholler> some unimportant information ;)
[04:31:26] <Dan211> additionally, I cannot communicate with my PC at > 115.2k (using ttl -> RS232 converter)
[04:31:50] * harshpb (~harsh@122.167.99.242) has joined #beagleboard
[04:31:50] <Dan211> But my Arduino can communicate with my PC at > 115.2k
[04:31:52] * harshpb (~harsh@122.167.99.242) has joined #beagle
[04:32:16] <Dan211> furthermore, it looks like someone else is having this problem - https://groups.google.com/forum/?fromgroups#!topic/beagleboard/8MspWJgfFAI

[04:33:45] <aholler> Dan211: which converter? the one on the board itself?
[04:34:30] * ericb2 (~X@unaffiliated/ericb2) has joined #beagle
[04:34:53] <dm8tbr> mh, two things I wonder: a) is the level shifter fast enough / does it distort the signal b) does the UART timing differ somehow on both sides
[04:35:09] * emeb (~ericb@ip72-223-81-94.ph.ph.cox.net) Quit (Quit: Leaving.)
[04:35:18] <aholler> some people have a very short attention span
[04:36:07] <Dan211> even without the conversion from 3.3 -> 5V it should still work but it doesn't (only above 115.2k)
[04:36:15] <Dan211> I have also scoped the signal and it doesn
[04:36:18] <Dan211> * Doesn
[04:36:24] <Dan211> *doesn't look distorted
[04:36:30] * guanucoluis2 (~luis@200.127.183.41) Quit (Ping timeout: 260 seconds)
[04:36:59] <Dan211> I think it is most likely a timing issue or a bug in the UART configuration?
[04:42:38] * Russ (foobar@ip68-106-254-4.ph.ph.cox.net) Quit (Ping timeout: 240 seconds)
[04:42:46] <Dan211> UPDATE: It now looks as if I can get it working at 500kbps for Beagle -> Arduino if I put a slight delay between writing characters and I change the data bits to 7, i.e. 7N1????

[05:07:07] <ds2> ground? we don't need no stinking ground!
[05:07:13] <ds2> everything levitates here!
[05:07:26] <Dan211> the same setup is able to communicate at <= 115.2k
[05:08:48] <aholler> Dan211: you might try to raise the baudrate of the console (using uEnv.txt)

[05:09:25] <Dan211> Ok I will try that aholler, thank you!
[05:10:14] <aholler> so you could be sure it isn't your cabling or whatever because the onboard-ftdi is likely wired correctly
[05:11:46] <Russ> a good symptom of not having a good return path is 'I measured it and it's fine'
[05:14:22] <aholler> we have a german saying which is "Wer misst misst Mist". That translates to "who measures measures bullshit".
[05:14:34] <Russ> what a horrible saying
[05:14:44] <Russ> its like the asian saying that the nail that sticks up gets hammered down
[05:16:06] <aholler> the saying proved too often to be sure ;)
[05:16:21] <Russ> you can't get very far with circuitry without measuring :)
[05:17:29] <Dan211> aholler, uEnv.txt only seems to contain "optargs=run_hardware_tests quiet"
[05:20:09] <jay6981> was that a mao quote?
[05:20:17] <aholler> you can add "console=ttyO2,115200n8"

[05:21:24] <aholler> but I know he can more than 500k
[05:21:39] <Dan211> ok thanks, Linux is still quite new for me

[05:28:29] <jay6981> full disclosure there :)
[05:28:48] <Dan211> I changed it to ttyO0 since uart0 is used for the console on the bone. It did not work unfortunately (still communicated at 115.2k)

[05:40:34] <aholler> Documentation/serial-console.txt says "The maximum baudrate is 115200."
[05:41:00] <aholler> so there is the limit (for the console).
[05:41:31] <aholler> but if you have a ssh-connection, you can just use a terminal programm like minicom
[05:41:32] <dm8tbr> you might be able to push it higher in non-obvious non-straight-forward ways though :)

[09:19:47] <vigoo> Hi, when programming the beaglebone from CSS in Win7 I often get into a state which requires to power down the beaglebone and connect to target again. I wonder if my system will turn stable if I somehow get to completely remove Linux from the SD card? If so how would I do this?
[09:25:36] <aholler> by just removing the card?
[09:26:26] <aholler> but I think writting error-free code is a better approach

[13:22:27] <stuk_gen> because i don't want a surprise...if after much hours i have a kernel < 3.x...
[13:22:40] <mdp> av500, although nice, that handset display is too unwieldy to carry in my pocket
[13:23:11] <stuk_gen> but if you can says 'don't worry the bitbake use the latest kernel testing and this is sure >3.x' i will trying...
[13:23:24] <av500> stuk_gen: you could also have a peek inside the kernel recipe
[13:25:53] <stuk_gen> ok...so the ways are 2... or use buildroot that download build and create image for package that i need... ore use angstomm and install after on the targer via opkg the package that i need
[13:26:18] * tema (~tema@178-16-155-142.obit.ru) has joined #beagle
[13:27:07] <stuk_gen> ...last question...how many times and size require the build of angstrom?
[13:27:36] <av500> you dont need to build angstrom
[13:27:43] * GPSFan (~kenm@64.92.145.112) has joined #beagle
[13:27:46] <av500> you can just install the packages you need

[13:27:56] <mru> once if you do it right the first time

[13:28:59] <stuk_gen> av500: hoe can you get latest angstrom demo? via narcissus or other?
[13:29:01] <av500> then, if you need a new kernel, yes clone the git and bitbake a kernel
[13:29:02] <stuk_gen> how*

[16:36:42] <Russ> gah, I really need ops in this channel
[16:36:46] <jay6981> goodpeer use pastebin or you'll get kicked out
[16:37:06] <aholler> Russ: yes, ask jkridner_
[16:37:07] <arcanescu> goodpeer: once there paste all this junk in there
[16:37:29] <arcanescu> goodpeer: once pasted send us the small http:// link ok ? yes then we will family your request
[16:37:59] <goodpeer> sorry for the paste. I will try to do it.
[16:38:13] <arcanescu> goodpeer: now you are acting like a goodpeer
[16:38:32] <jay6981> family your request? lol
[16:38:39] <arcanescu> yes
[16:38:43] <arcanescu> that what he said

[16:38:58] <jay6981> yeah he's got a very odd dialect
[16:39:02] <arcanescu> so its best to speak to him in what he gets

[16:41:00] <goodpeer> apart from the slow boot up issue,
[16:41:33] <goodpeer> how can I block the modules at startup
[16:43:37] <goodpeer> I guess the problem of my angstrom version is something wrong in clock?
[16:46:24] <goodpeer> I use angstrom-gnome-image, anyone got clue why this image was so slow at the first boot

[16:50:58] <goodpeer> so you mean this is the main reason why it is so slow at the first boot
[16:51:08] <Russ> yes
[16:51:40] <Russ> there could be other factors, but that is what makes the first boot slower than subsequent boots

[16:52:02] * davest (~dcstewar@134.134.139.74) has joined #beagleboard
[16:52:18] <Russ> there is a lot more to booting than just the kernel
[16:52:48] <Russ> This line is your pastebin:
[16:52:51] <Russ> [ 2.642944] VFS: Mounted root (ext3 filesystem) readonly on device 179:2.
[16:53:06] <Russ> indicates the kernel is done booting
[16:53:09] <goodpeer> i know. I mean the beagle test imag was faster
[16:53:15] <goodpeer> yes.
[16:53:22] <Russ> for that you need bootchart
[16:53:51] <Russ> dmesg just tells you the timing for the kernel, bootchart tells you the timing for everything else
[16:54:01] <Russ> http://www.bootchart.org/
[16:54:10] <goodpeer> thanks I will do this later
[16:54:12] <Russ> I've never looked, but angstrom probably has support
[16:54:45] <goodpeer> one question about how to block modules at the booting stage
[16:55:22] <goodpeer> I tried to write a config file and put it into modules-load.d
[16:55:39] <goodpeer> then use update-modules to generate a file called modules at /etc
[16:56:03] <goodpeer> but it was not working to block some modules that I don't want to be loaded
[16:56:55] <goodpeer> and once my angstrom version booted, there was no network service
[16:57:14] <goodpeer> i had to use /etc/init.d/networking restart to get network up
[16:58:38] <goodpeer> the third question is everytime the board was booted, the date and time automatically reset back to 1970
[16:59:13] <goodpeer> i doubt the timer code was not working
[17:00:32] <aholler> do you have seen a battery on the board?
[17:01:17] * davest (~dcstewar@134.134.139.74) Quit (Quit: Leaving.)
[17:01:50] <goodpeer> no. there is no battery
[17:02:08] <aholler> the srm describes what to do
[17:03:16] <goodpeer> ok. thaks
[17:03:20] <goodpeer> thanks
[17:04:17] <goodpeer> any advice for how to block modules?
[17:05:15] <aholler> maybe you want to describe what your config file contains.
[17:05:19] <mdp> jsabeaudry: remind me, it was edma fifo mode that didn't work for you, right? so you used increment mode with 0?

[17:08:19] <goodpeer> then nothing more special.
[17:08:26] <aholler> I mean the one you've created to block modules
[17:08:46] <koen> fwiw, angstrom only has bootchart2, not bootchart

[18:09:02] <jsabeaudry> mdp, well it's not really that it didnt work but that the "requirements" are so prohibitive
[18:09:49] <jsabeaudry> mdp, the fact what you need to be 256 bits aligned is a deal breaker for me
[18:10:32] <mdp> hrm, ok..ahh, that explains that comment
[18:10:51] <jsabeaudry> may make sense when you have a 256bit wide fifo bu mine is only 16 bits
[18:11:00] <mdp> sure
[18:11:01] <jsabeaudry> I have 16 of them
[18:11:29] <jsabeaudry> Have you found anything new regarding lockups with the edma test app?
[18:11:35] <mdp> I was given a drive to review/debug that has non-working edma support
[18:11:47] <mdp> oh, I followed up on that, probably when you were away
[18:11:59] <mdp> it's a TI documentation issue
[18:12:00] <jsabeaudry> the 3 vs 4 TC thing?
[18:12:04] <mdp> yes
[18:12:08] <jsabeaudry> whats a TC?
[18:12:18] <mdp> linking to the 81xx specific sample app
[18:12:22] <mdp> transfer controller
[18:12:47] <mdp> edma is composed on a channel controller block and 1???N transfer controllers that actually do the work
[18:13:22] <jsabeaudry> oh yes and you can link the TCs
[18:13:26] <mdp> the CC block does all the management of "channels", priority, queuing based on all the triggering methods and param definitions
[18:14:06] <mdp> then that is used to hand everything off to the TCs..they have more on 81xx, cause there's more "stuff" on it :)
[18:14:12] <mdp> for lack of a better description
[18:14:55] <mdp> and the TRM is misleading as usual???shows a block diagram right up front for am335x indicating that there are 4 TCs???there is not

[18:21:22] <mdp> jsabeaudry, perhaps you'll find this amusing???this driver is checking for 32-bit alignment on the fast path and then using fifo mode.

[18:22:12] <jsabeaudry> 32 bits or bytes?

[18:23:19] <mdp> bits brother! did I stutter? :)
[18:23:44] <mdp> but good question :)
[18:23:55] <jsabeaudry> nah its just that it should be looking for 32 bytes alignment
