**** BEGIN LOGGING AT Thu Nov 14 02:59:59 2013 Nov 14 03:02:09 ah man I can't even find the right packages Nov 14 03:02:30 http://feeds.angstrom-distribution.org/feeds/v2013.12/ipk/eglibc/armv7a-vfp-neon/python/ Nov 14 03:02:37 older than what's currently on my board Nov 14 03:02:38 ! Nov 14 03:02:59 has anyone installed fedora on bbb? Nov 14 03:04:32 no like debian armhf? Nov 14 03:04:53 jonpry: does it have apt ? Nov 14 03:05:01 yes Nov 14 03:05:10 what kind of debian wouldn't have apt? Nov 14 03:06:32 one that you run buildroot on and reboot into Nov 14 03:06:36 I'm really tired Nov 14 03:06:46 hoping to get this working in 30 mins Nov 14 03:07:35 why did they ship it with this linux? Nov 14 03:07:43 why not slackware or debian or something else? Nov 14 03:07:58 i don't understand this angstrom stuff either Nov 14 03:08:09 but switch to debian is easy Nov 14 03:10:17 i switched to debian Nov 14 03:10:23 its been far less annoying Nov 14 03:10:59 I prefer slackware or fedora, debian isn't that bad either Nov 14 03:11:10 but angstrom???? Nov 14 03:11:21 weird choice as the default distro Nov 14 03:11:58 angstrom was the first to support the hardware... so not such an unusual choice Nov 14 03:12:11 ah okay Nov 14 03:12:16 you mean first to support ARM? Nov 14 03:12:25 no Nov 14 03:12:56 first to support the beagle products, at least in recent history Nov 14 03:13:26 ti has been using angstrom since before debian armhf and probably before armel worked very well Nov 14 03:16:52 still compiliing python 2.7.6 Nov 14 03:17:21 I got too attached to good processing power Nov 14 03:17:40 i switched to ubuntu.... it's been so much nicer Nov 14 03:17:49 angstrom uses ancient packages.... ruby was still on 1.9.3 :( Nov 14 03:18:30 interesting nickname bahar Nov 14 03:19:21 thanks Nov 14 03:20:13 please can someone point me to a reference on how to setup a DHCP server with beaglebone and ubuntu(running on beaglebone) and debian on my mahcine Nov 14 03:20:20 or something similar Nov 14 03:20:37 but im booting the beaglebone from a microsd card Nov 14 03:20:50 and want to ssh to the beaglebone Nov 14 03:23:17 where can I get python-smbus ? Nov 14 03:23:23 I need the source Nov 14 05:39:37 frege: Have you EVER done that before? Nov 14 05:40:41 oops, I meant jenia* Nov 14 05:40:59 jenia: Have you EVER done that before? (there fixed haha) Nov 14 05:42:36 hehe Nov 14 05:42:39 no never Nov 14 05:42:44 but i want to Nov 14 05:43:03 of course i cant without any references. Nov 14 05:43:19 if you know of any tutorial or combination tutorial i can go though Nov 14 05:43:47 i would be eternally grateful because you will have helped achieve something serious and wonderful Nov 14 05:43:57 <_av500_> settingup a dhcp server on ubuntu is like on any other ubuntu system Nov 14 05:44:02 <_av500_> apt get install something Nov 14 05:44:10 <_av500_> its ubuntu after all Nov 14 05:44:16 _av500_: He/she just stated he/she never has done it before Nov 14 05:44:18 do i set up a DHCP on my debian system (pc) Nov 14 05:44:25 _av500_: Which is why I asked what I asked. Nov 14 05:45:09 jenia: First thing I would learn is how to install a server image of Ubuntu on a machine (even your beaglebone if you want) Nov 14 05:45:11 and then the ubuntu running on the beagle will contact the dhcp server and assign itself a ip address that i will be able to find with nmap" Nov 14 05:45:12 ? Nov 14 05:45:18 i already it did Nov 14 05:45:36 i only need to ssh to the ubnutu on the beagle from the debian on my machine Nov 14 05:53:43 jenia: https://help.ubuntu.com/community/dhcp3-server Nov 14 05:55:21 jenia: That's of course assuming you already have a server install of Ubuntu on a given machine. Nov 14 05:56:47 jenia: you just need to figure out what ip address the board got so you can ssh to it? Nov 14 06:13:30 thanks Nov 14 06:13:51 so the DHCP server will run on debian right Nov 14 06:13:52 ? Nov 14 06:13:56 (on the pc) Nov 14 06:14:34 and the unbutn kernel (on the beagle) or some driver thats installed with it will be able to implement the DHCP client protocol Nov 14 06:14:39 basically like that? Nov 14 06:16:44 the dhcp client is *usually* a user-space process, although it could be built into the kernel Nov 14 06:17:23 most OSes default to using a dhcp client for the network Nov 14 06:19:28 jenia: how does your debian machine get it's network configuration? or you want to set up an isolated network between your debian computer and the beaglebone? Nov 14 06:35:39 i feel a little shame but i cant answer Nov 14 06:35:42 hehe Nov 14 06:36:02 are you saying i already have a dhcp network set up? Nov 14 06:36:18 the server running on the pc/debian system Nov 14 06:37:19 jenia: if your debian machine has internet access, you probably have a dhcp server set up somewhere on your network Nov 14 06:37:40 jenia: such as a DSL/cable modem Nov 14 06:38:34 jenia: is your goal just to ssh to the beaglebone? Nov 14 06:38:47 so does that mean i should have the beagle/deabian machine visible on the network easily Nov 14 06:38:56 iwth nmap for example? Nov 14 06:39:08 beagle/ubuntu*** Nov 14 06:39:12 if you plug it into the same network, it should be visible, sure Nov 14 06:39:22 into the router? Nov 14 06:39:25 unless there's a misconfiguration or something Nov 14 06:40:18 is the DHCP running on the router? Nov 14 06:40:27 hehe maybe not but i just want tto make sure Nov 14 06:47:18 jenia: usually a router runs a dhcp server, yes. Nov 14 06:48:07 nice that i asked Nov 14 06:48:08 haha Nov 14 06:48:11 thanks very much Nov 14 10:13:06 test Nov 14 10:13:12 If i want to write an image from a uSD card to the eMMC using the dd command, how would i go about it? Google searching just gives me results about copying the image from a PC onto the uSD card Nov 14 10:13:12 any one here? Nov 14 10:13:45 I have a question Nov 14 10:14:15 Is it possible to configure BBB as a hid input device? for example to emulate mouse Nov 14 10:15:58 ste: Using dd? Nov 14 10:16:09 oops, ste* Nov 14 10:16:14 damnit Nov 14 10:16:18 jjc** Nov 14 10:16:26 Looooooooong night haha Nov 14 10:17:23 take a nap maybe? Nov 14 10:17:42 I can't! I wish, newborn baby and deadlines to meet Nov 14 10:18:15 not to mention two needy dogs Nov 14 10:19:36 it's life then Nov 14 10:19:53 drop the dogs Nov 14 10:20:00 only costs moneny Nov 14 10:20:28 I wish I only saw them as dogs. Nov 14 10:20:41 And my girl would kill me. Nov 14 10:23:11 drop the girl too Nov 14 10:23:17 lol Nov 14 10:23:47 I was just about to say "the only solution would be to leave all of them and pay for child support. Then visit my child". But I think that would hurt me Nov 14 10:24:21 eggzeck-laptop you could tell the court the dogs attacked the kids Nov 14 10:24:29 that would solve all problems Nov 14 10:24:49 haha Nov 14 10:25:40 hello guys, Angstrom-DIstribution page not working? Nov 14 10:26:53 Anyone? I cant find any pages from their website angstrom-distribution.org, portal Shifted? Nov 14 10:27:25 Kevinrz2: Seems to be down atm Nov 14 10:27:29 Kevinrz2: What do yo uneed? Nov 14 10:28:11 Kevinrz2: If it's just a new image for your beaglebone go here: http://www.beagleboard.org/latest-images Nov 14 10:28:18 i needed to see the packages Nov 14 10:28:30 get the x264 libraries Nov 14 10:28:34 for gstreamer Nov 14 10:29:16 its Been down for quite some time now .... something dosn't seem right. Nov 14 10:29:41 I haven't noticed, what's quite some time? Nov 14 10:29:48 Kevinrz2 opkg does not work? Nov 14 10:29:52 like for th past week Nov 14 10:29:58 the website was not accesible Nov 14 10:30:32 hm there was a us mirror somewhere Nov 14 10:30:48 but you could ask in the angstroem channel too Nov 14 10:32:25 eggzeck-laptop: yep using dd Nov 14 10:33:42 eggzeck-laptop: it doesnt have to be, it just seemed like it was the easiest option, if you know of another better option I would be glad to hear Nov 14 10:34:44 ok, stupid question, how do i join Angstrom IRC? Nov 14 10:36:17 Kevinrz2: type "/j #angstrom" in your IRC client Nov 14 10:37:57 thank u sir :) Nov 14 10:40:47 is there any android image that can be flashed on the eMMC for the BBB ? Nov 14 10:40:57 jjc: Nov 14 10:41:06 jjc: "cp" would do just fine, no need to use "dd" Nov 14 10:41:30 cp will write the image? Nov 14 10:43:06 eggzeck-laptop: Nov 14 10:44:17 vvu|Log: there are android images, no? Nov 14 10:44:18 jjc: Oh sorry, I misunderstood what you wanted to do. Nov 14 10:45:01 av500: yes but directly that can be flashed on the eMMC not uSD ones, somebody sent me an email asking something like this. Nov 14 10:45:17 well Nov 14 10:45:20 he is suing my beagleboot project Nov 14 10:45:21 repack it for emmc Nov 14 10:45:26 ic Nov 14 10:47:38 Kevinrz2: something seems to have gone wrong with linuxtogo where Angstrom is hosted, we are still waiting to hear from them, I assume it is a non trivial issue Nov 14 10:55:27 oh thank god :) i thought someone bought it and stuff lol :/ long live Open Source!! Nov 14 10:55:33 thanks for the info XorA Nov 14 10:56:10 Kevinrz2: no, the domain is safely held by Crofton|work AFAIK Nov 14 10:56:26 ye, autorenew on credit card Nov 14 10:57:19 Crofton|work: have to admit first thing I did when it went AWOL was check the whois :-D Nov 14 10:57:36 :) Nov 14 10:58:02 Crofton|work: did you chat with florian, I have not been around last couple of days Nov 14 10:58:14 I haven't had a chance Nov 14 11:00:10 florian: ping, any news on LTG issues? Nov 14 11:00:19 * florian waves... one sec. just returned to the office after fixing a car :) Nov 14 11:03:55 Yes I have news... someone used the machine to attack some other one and the provider disconnected it :-/ Unluckily we have quite some people with shell access... I currently sorting out how to get access and trying to "fix" this. But it will take a while... Nov 14 11:04:20 ouch Nov 14 11:04:33 florian: thanks for update Nov 14 11:13:50 sounds like we need to send the OE mafia after someone Nov 14 11:42:40 hi Nov 14 11:44:25 morjens Nov 14 11:44:56 hi! Nov 14 11:48:19 hi Nov 14 11:48:39 anyone available online now... Nov 14 11:48:40 ??? Nov 14 11:53:24 Not only anyone, but everyone. Nov 14 12:14:31 i am not getting register a project in beaglebone.org project site Nov 14 12:28:22 What? Nov 14 12:31:45 On PRUs. Nov 14 12:32:26 I'm interested in taking a parallel ADC and connecting to the BBB. This would ideally buffer to a large buffer in main RAM. Nov 14 12:32:58 What sort of speed can I get (assuming optimal things) if I have a PRU doing reading and writing to main RAM? Nov 14 12:33:36 * KotH points at panto Nov 14 12:33:45 but the lazy greek guy is out for lunch Nov 14 12:34:08 hi Nov 14 12:34:16 Hi. Nov 14 12:34:47 Hi ZiNC Nov 14 12:34:49 Lo Nov 14 12:34:58 SpeedEvil, I think you'll be mostly limited by DRAM b/w Nov 14 12:35:06 is http://www.angstrom-distribution.org/ site down? Nov 14 12:35:07 and stalls due to arbitration Nov 14 12:35:19 how fast is your ADC? Nov 14 12:35:32 panto: I'm assuming some sort of FIFOy thing with the 8K RAM Nov 14 12:35:44 panto: Let's say arbitrarily fast for the moment. Nov 14 12:35:51 just write it directly to dram Nov 14 12:36:03 Vaizki: That will suffer from stalls. Nov 14 12:36:18 in that case I'd use a pipelining scheme Nov 14 12:36:35 have PRU0 read from ADC, store to shared SRAM (0 stalls) Nov 14 12:36:40 can the prus dma stuff out? Nov 14 12:36:43 and have PRU1 store to DRAM Nov 14 12:37:01 Vaizki, they can, but the setup/teardown cost of the DMA channels is not worth it Nov 14 12:37:09 ok Nov 14 12:37:13 remember you only have a couple of K at most in internal SRAM Nov 14 12:37:22 panto: yeah - that was basically what I was assuming. Nov 14 12:37:22 the PRU _is_ your DMA Nov 14 12:38:10 well, if you're doing general signal conditioning storing the values in some kind of compressed delta format will save a log of b/w Nov 14 12:38:19 you don't have to store the raw values Nov 14 12:39:13 you will be limited by DRAM b/w anyway, optimize for it Nov 14 12:39:15 panto: I want basically an oscilloscope. Nov 14 12:39:47 panto: And in principle, the BBB has >200MB/s memory bandwidth. So that's not the answer. Nov 14 12:40:04 why do you want to do it with a BBB then... Nov 14 12:40:17 SpeedEvil, _shared_ bandwidth Nov 14 12:40:20 Vaizki: Because it's much, much cheaper in some cases. Nov 14 12:40:34 and that assumes full cache line fills Nov 14 12:40:42 How 200MB/sec? Nov 14 12:40:54 panto: Right - transferring a full cacheline at a time isn't an issue. Nov 14 12:41:12 (Given the 8K buffer) Nov 14 12:41:18 you're not the only one accessing DRAM Nov 14 12:41:32 lots of bus masters Nov 14 12:42:30 like full HD video decode at the same time Nov 14 12:42:37 Is the memory bus 16-bit? Nov 14 12:42:58 can't recall exactly but I think yes Nov 14 12:43:06 I would probably get a Spartan FPGA or something.. Nov 14 12:43:11 anyway, lunch time Nov 14 12:43:13 but no, I don't know what I'm doing here :) Nov 14 12:43:45 Vaizki: Beagle is ratehr cheaper than a FPGA with several hundred meg of memory. I was wondering about the limits. Nov 14 12:43:49 SpeedEvil: you could write a small PRU app that just writes to SDRAM Nov 14 12:43:50 Bon appetit. Nov 14 12:43:53 and see how fast it gets Nov 14 12:44:00 av500: that was basically what I was wondering about Nov 14 12:44:06 av500: no HW at the moment Nov 14 12:44:41 av500: also - I do wonder what the input limits would be. Can you in fact read the port pins in back to back 200MHz reads and get reliably different results? Nov 14 12:47:39 PRU runs at 200mhz Nov 14 12:47:54 that does not mean you can read port pins at 200mhz Nov 14 12:48:21 I know. Nov 14 12:48:49 either you sync to some clock, or you make the clock Nov 14 12:48:56 I haven't found any answer as to how fast the PRU can read them and get reliable answers despite a few minutes of searching Nov 14 12:49:17 I understand you can read/write a GPIO at every cycle Nov 14 12:49:25 so that should be OK Nov 14 12:49:27 Even neglecting the memory bandwidth. Nov 14 12:49:40 hmm Nov 14 12:49:42 GPMC Nov 14 12:49:48 with DMA Nov 14 12:49:53 av500: you can read it - sure. If you have a 100MHz squarewave (of the right phase) and you issue two reads - will you actually get the right figures. Nov 14 12:50:10 if you can do DMA chaining you can set it up and it will fill ping pong buffers on its own Nov 14 12:50:26 SpeedEvil: you need sync to a clock Nov 14 12:50:59 I guess GPMC can generate a read clock Nov 14 12:51:04 and you can use that to clock your AD Nov 14 12:51:10 av500: In most cases, yes, and that would generally be the only sane way of doing it. I know that the PRU can do clocked reads - but have been unable to find clock speed limits. Nov 14 12:51:13 so you read as fast as GPMC can input data Nov 14 12:51:21 ah Nov 14 12:51:27 no idea about clocked reads on PRU Nov 14 12:51:57 on GPMC, yes Nov 14 12:52:05 basic DMA Nov 14 12:52:26 What's the maximum DMA clock then? Nov 14 12:54:41 no idea, RTFDS :) Nov 14 12:55:02 the maximum gpmc clock is 100mhz @ 16bit Nov 14 12:55:08 jonpry: thanks! Nov 14 12:55:23 jonpry: Is this reflective of actual read ability on the pins? Nov 14 12:55:29 yes Nov 14 12:55:33 otherwise it makes little sense Nov 14 12:56:07 need burst transfers for high throughput Nov 14 12:57:36 hmm Nov 14 12:58:35 not sure how you would really attach an ADC without some kind of fpga for glue Nov 14 12:58:46 why? Nov 14 12:58:52 why not use gpmc Nov 14 12:59:14 assuming gpmc can have a fixed data rate Nov 14 12:59:35 if it cannot, yes then you need a fifop Nov 14 12:59:37 -p Nov 14 12:59:48 jonpry: you connect the clock and data pins to the GPIOs, connect the appropriate supply and other voltages, and press the green button Nov 14 13:00:59 i thought you wanted gpmc? Nov 14 13:01:33 I am entirely uninterested in the way it goes from pins to memory. Nov 14 13:01:47 gpmc is different pins Nov 14 13:02:09 I just am trying to work out the answer to 'what is the fastest way of without stalls to go from clocked pins into memory reliably' Nov 14 13:03:06 SpeedEvil: if you really want to do an oscilloscope type thing, i would recommend that you use an FPGA for ADC memory handling Nov 14 13:03:21 PRU seemed one possibility, as does clocked DMA. I wasn't able to find answers in the docs I looked at. I may need to re-read, but often this sort of question can provoke people who've seen a project that does this. Nov 14 13:03:39 SpeedEvil: a fast ADC can generate more than 500Msps @8bit, which is impossible to handle with a normal uP Nov 14 13:04:02 KotH: I understand, and agree in one sense. However, it would still be useful if the answer was '20MHz' Nov 14 13:04:19 SpeedEvil: ie, store it in a massive parallel DRAM buffer using the FPGA, then clock it out slowly through the GPMC Nov 14 13:04:22 I'm just trying to understand if it's 2, 40, or 100MHz Nov 14 13:04:47 SpeedEvil: 100Msps@8bit should be possible if you are able to hanlde full cachelines Nov 14 13:04:49 KotH: that is considerably harder, for a number of reasons, and involves quite a lot of extra hardware. Nov 14 13:05:07 i just glued something onto gpmc using a $1.20 fpga Nov 14 13:05:14 I do agree FPGAs are cool. Nov 14 13:05:25 SpeedEvil: above 200Msps you will have problems finding an ADC with parallel interface :) Nov 14 13:05:33 but it's only 8-bit @ 25mhz and read takes 3 cycles Nov 14 13:05:56 SpeedEvil: have a look at the BCC cape Nov 14 13:06:02 SpeedEvil: has a spartan6 on it Nov 14 13:06:10 SpeedEvil: should be more than enough logic to get you started Nov 14 13:06:30 SpeedEvil: probably even enough on chip ram to store a full sample run from the ADC w/o additional dram Nov 14 13:06:32 Cost is an issue. Nov 14 13:07:33 http://i.imgur.com/QFWt4hZ.jpg Nov 14 13:07:40 a spartan6 is cheaper than the bbb :) Nov 14 13:08:05 500MSPS 8 bit ADC is 38 quid Nov 14 13:08:06 SpeedEvil: what is your exact application and target audience? Nov 14 13:08:37 KotH: I'm wondering about a cheap 'oscilloscope' with relatively poor triggering capability and a very deep memory. Nov 14 13:08:38 SpeedEvil: there is a 200Msps 8bit from NXP that is very cheap Nov 14 13:08:45 KotH: and yes. Nov 14 13:09:39 SpeedEvil: yes what? Nov 14 13:09:48 The PRUs were interesting in principle as they perhaps have enough smarts to do rudimentary triggering. Nov 14 13:09:58 There are much cheaper ADCs if you go down in frequency Nov 14 13:10:48 4 dollars at 8 bit 80msps Nov 14 13:13:16 i think the gpmc clock will just get a ton of jitter if you try to continuously read from it Nov 14 13:13:46 it's not free running. so whenever another AXI transaction is in progress the clock will end up stalling Nov 14 13:14:25 SpeedEvil: you can use more than one ADC and do staggered sampling Nov 14 13:14:44 SpeedEvil: especially the ADI parts have high analog bandwidths Nov 14 13:14:51 jonpry: Hence why I was wondering initially about the PRUs Nov 14 13:15:07 they don't have exclusive access to AXI or anything Nov 14 13:15:29 SpeedEvil: uhmm... the jitter of the CPU clock is probably not good enough. i dont know how well it is specified Nov 14 13:16:07 SpeedEvil: probably it would be a good idea to clock the ADCs from a seperated, but to the CPU clock locked VCO/VCXO Nov 14 13:17:35 The jitter of the internal PRU clock if it's clocked from a PLL should be quite adequte. I was assuming I could basically do a FIFO - one PRU reads - one writes to RAM using the 8K as a fifo buffer. Nov 14 13:17:54 PLL or clock divisor Nov 14 13:18:11 I need to more fully read the PRU docs. Nov 14 13:18:29 i wouldnt be so sure Nov 14 13:18:29 a cpu clock can easily accomodate a multi-ps jitter Nov 14 13:18:34 for an ADC running at >100Msps, 1ps is an extremely high jitter Nov 14 13:18:55 you'll easily lose 1-5bit just by that Nov 14 13:20:29 I agree, in principle. In practice, there are ways to reduce that that are rather simple. Nov 14 13:21:16 (as long as the jitter doesn't exceed a few tens of degrees, a simple PLL would work. Nov 14 13:25:31 that reduces your effective sampling rate Nov 14 13:25:48 you can do all those tricks, no problem Nov 14 13:25:52 but you will lose information Nov 14 13:25:55 either bits or rate Nov 14 13:26:08 TANSTAFL Nov 14 13:26:56 how do I mount the sd card from debian? Nov 14 13:27:01 booted from mmc Nov 14 13:27:30 KotH: No, it doesn't. Nov 14 13:28:04 SpeedEvil: how? Nov 14 13:28:15 KotH: You have a clock with 10 degrees of jitter. You generate a smoothed clock with 0 jitter and offset it 10 degrees so that it never crosses the other clock and clock your ADC from that. Nov 14 13:28:19 Korra: mount Nov 14 13:28:37 SpeedEvil: eh.. Nov 14 13:28:46 SpeedEvil: that's what i meant by using an external clock Nov 14 13:29:31 Sorry - I'm not properly awake today - I should probably leave it for another day - but... Nov 14 13:29:50 and the sd card device name is? Nov 14 13:31:45 Korra: your kernel tells you that Nov 14 13:32:04 Korra: and no, i dont know it Nov 14 13:32:07 ok and how do I query for that? Nov 14 13:32:11 kernel log Nov 14 13:32:20 dmesg or /var/log/kern.log Nov 14 13:32:27 and get yourself a book on linux basics Nov 14 13:32:28 you need it Nov 14 13:34:17 tbh what I need is a softfloat debian image and not to be spending a week jumping through fire hoops of low level linux stuff Nov 14 13:34:27 but I take what I get Nov 14 13:35:06 tbh if you expect to work with an embedded linux system, you will need quite some "low level linux stuff" knowledge Nov 14 13:35:17 otherwise you will hit your head against a wall at every turn Nov 14 13:35:39 even if you run "end user" distros like ubuntu Nov 14 13:35:50 embedded is a complex beast, no matter how you try to hide it Nov 14 13:36:01 if you dont know what you are doing, you will fail Nov 14 13:36:03 I've been finding that out yeah Nov 14 13:36:49 and yes, i blame all those OH and RPI advocates for telling people that everything is oh-so-simple and you can use it as a replacement for your PC and do a lot more with it! Nov 14 13:36:59 Rober Nelson's Ubu scripts are a nice fast start Nov 14 13:37:14 its a big and sometimes not well mapped ecosystem, I haven't had to get on irc to ask questions in years but here I'm frequently getting problems that there's just no instant google answer for Nov 14 13:37:35 it's a learning experience =) Nov 14 13:38:00 I'm still battling getting RS-485 working on BBB Ubuntu Nov 14 13:38:14 Korra: well.. it is well mapped. but the amount of knowledge you need is vast Nov 14 13:38:23 Korra: you cannot expect to learn it just in a couple of days Nov 14 13:38:26 The rs485 cape doesn't work for BBB, only the White Nov 14 13:38:47 Korra: it starts from low level unix knowlege and goes to electronic interfaces and how to solder Nov 14 13:39:24 well, I certainly know how to solder and I'm happy to learn Nov 14 13:39:41 but yeah I kinda rode on the rpi wave Nov 14 13:40:06 'oh sweet a cheap embedded device to host mono for my project' Nov 14 13:40:51 2 best uses for RPi for me has been the RPi-TC project and RASP-XBMC project Nov 14 13:41:13 TooLmaN any idea if rs232 cape works? Nov 14 13:41:21 I'm running 2 web-based apps on large displays via RPi Nov 14 13:41:28 Korra: RS232 works fine Nov 14 13:41:33 thank god Nov 14 13:41:48 The rs485 was build to use the same UART slots as the eMMC Nov 14 13:42:22 would it be difficult to use a usb dongle for the same thing? Nov 14 13:42:27 I'm experimenting with the RS485 Click board from www.mikroe.com now. Just got it yesterday Nov 14 13:43:28 I haven't seen a RS485-USB dongle, but I imagine I'd run into the same issues with UARTS and control spaces. I want to keep the RS485 in the Serial Control Space Nov 14 13:43:54 We plan to use the ethernet system as well Nov 14 13:44:15 Basically for standard networking but other stuff on the horizon Nov 14 13:44:17 a la http://www.tronisoft.com/prod.php?id=2459 Nov 14 13:45:34 Korra: good find! I'll see if the driver is compatible. According to Torvalds himself, only a limited number of CPUs natively support RS485 Nov 14 13:45:57 let me know what you find please Nov 14 13:46:05 this is of interest to me but also over my head atm Nov 14 13:46:15 luckily I can use rs232 for now Nov 14 13:46:19 Will do. It was over my head until last week lol Nov 14 13:56:01 is the sd card gonna be in /dev/ for sure? Nov 14 13:58:35 Oct 25 18:09:11 arm kernel: [ 2.665020] mmc0: new high speed SDHC card at address aaaa Nov 14 13:58:37 I don't even Nov 14 13:59:39 that's probably the emmc, if you booted from that Nov 14 14:00:34 any idea what I'm looking for regarding the sd card then? Nov 14 14:00:36 or what I google for Nov 14 14:11:34 /dev/mmcblk0p1 apparently Nov 14 14:11:49 because 'mmc' is a totally legit identifier for the sd card I guess Nov 14 14:14:19 Korra, yes, sd or mmc will show up as mmcblk devices Nov 14 14:15:18 yup worked that out from attempting to mount everything that looked relevant Nov 14 14:15:25 was faster than thrawling the kernel log for I don't know what Nov 14 14:16:36 lsblk is always nice Nov 14 14:16:53 oh! Nov 14 14:16:55 awesome Nov 14 14:17:03 thanks Nov 14 14:17:10 np .) Nov 14 14:17:27 Vaizki uh yes nice Nov 14 14:17:36 ��mmcblk0p1 179:1 0 64M 0 part /mnt/sd1 Nov 14 14:17:39 strange naming there though Nov 14 14:18:01 some idiot decided to use ascii art for a tree view Nov 14 14:18:12 lsblk -i Nov 14 14:18:13 �, really? Nov 14 14:18:24 ah Nov 14 14:18:26 thanks again Nov 14 14:18:47 np (message repeated 2 times) Nov 14 14:19:30 I don't know what's wrong with tab indenting but that's linux development for you :) Nov 14 14:20:03 It's.. better than the kernel log Nov 14 14:21:48 there's also /proc/partitions if you don't happen to have lsblk Nov 14 14:22:32 not to mention /sys/block tree :) Nov 14 14:23:13 all good to know Nov 14 14:23:32 the /sys/block is pretty similar to what I found in /dev/ Nov 14 14:25:18 Hitting my mental wall this morning, must need more coffee. I ran "/bin/sh /boot/uboot/tools/ubuntu/small-lxde-desktop.sh" from "http://elinux.org/BeagleBoardUbuntu" and I got a desktop but no mouse. How can I revert the BBB back to booting to a console instead of X? My ol'skool runlevel knowledge seems to be depreciated now. :( Nov 14 14:26:17 I want to have X installed but now my default RL on boot Nov 14 14:26:19
