Feb 28 15:26:16 agmlego, true Feb 28 15:26:20 why stop at three? Feb 28 15:26:31 I was amazed to see how well the google self driving car did in traffic last week.

Feb 28 15:41:52 160kph is fairly normal here Feb 28 15:41:54 KotH, yes, we know. Feb 28 15:42:05 KotH: going up or down? Feb 28 15:42:06 ka6sox: still using a steam engine?

Feb 28 15:45:40 ka6sox: weird thing is, if you need any high tech devices from the surplus marked, the us is the place to go Feb 28 15:45:50 market* Feb 28 15:46:01 mmmmm...strawberries... Feb 28 15:46:06 ka6sox: getting here a used oscilloscope is nearly as expensive as buying a new one Feb 28 15:46:22 you don't have ebay? Feb 28 15:46:22 KotH, oh...I'll bet Feb 28 15:46:50 mru: shipping a 10y old monster costs more then the scope itself Feb 28 15:47:24 mru: it's cheaper to fly to NY w/o luggage, get one of those scopes and fly back with it Feb 28 15:47:42 Are there any way to set bpp in bootargs? Feb 28 15:47:46 KotH, surely you Jest?

Feb 28 15:48:39 mru: but i'd like to have something more modern... like a 200MHz DSO Feb 28 15:49:08 those cheapo analogue ones suck Feb 28 15:49:26 it's definitly not a cheap one... or at least it wasnt when first sold ;) Feb 28 15:49:33 I guess I need to get with the programme and retire my Tek 530 Feb 28 15:49:37 ah.. you mean the 200MHz DSO Feb 28 15:49:41 nah.. they arent that bad Feb 28 15:49:47 50MHz smells of cheap Feb 28 15:49:51 unless it's from the 60s Feb 28 15:49:57 prolly 80s Feb 28 15:50:41 joel_, koenkooi which version of 3.2.X did you have ALSA working right with? Feb 28 15:51:54 ka6sox: have a look at the MSO4104B-6 :-) Feb 28 15:52:51 got a spare 10K EUR? Feb 28 15:53:01 10keur? Feb 28 15:53:08 rather like 25k :) Feb 28 15:53:15 for certain values of spare, sure Feb 28 15:53:33 ka6sox: notice the -6 Feb 28 15:53:45 ka6sox: it denotes the "additional 6GHz RF input" option :) Feb 28 15:54:25 KotH, usually when I look that high I'm using a SA Feb 28 15:54:31 SA?

Feb 28 15:56:47 * KotH needs some serious analog guys help Feb 28 15:57:07 unfortunately, they are an nearly extinct species Feb 28 15:57:17 wb prpplague Feb 28 15:57:41 KotH, we used Impatt and Avalance Diodes (non photo) for getting to 6Ghz earlier in my career. Feb 28 15:57:47 prpplague: is the expedition to the unknown planed with it's unknown life forms over? Feb 28 15:58:23 ka6sox: hmm... Feb 28 15:58:42 ka6sox: any experiences with the generation of sub-ns pulses with high repetition rate? Feb 28 15:59:10 KotH: not that i am aware Feb 28 15:59:18 KotH: bold going where i haven't been before Feb 28 15:59:24 KotH: last day at TI Feb 28 15:59:29 prpplague: i thought you had a red shirt day? Feb 28 15:59:52 KotH: yes, my job is being killed Feb 28 15:59:57 KotH: last day Feb 28 16:00:09 * KotH hands prpplague a phaser Feb 28 16:00:13 for self defense ;) Feb 28 16:00:24 KotH, we only did sub-uS pulses with semi-high repetition rates...depending on the Target we wished to shoot down... Feb 28 16:01:21 ka6sox: hmm... i get to easily to 30ns with modern logic and a couple of cheap bjt... but i need to go below that Feb 28 16:02:07 I can send you a couple of 2N3904's in an envelope if you want... Feb 28 16:02:26 and a few 1N34's Feb 28 16:02:56 components are not the problem, digikey&mouser&co exists Feb 28 16:03:10 the problem is more how do i design a circuit to get into that region Feb 28 16:03:21 oh...stripline Feb 28 16:03:28 hmm? Feb 28 16:03:34 how does stripline help there? Feb 28 16:04:57 when I started out we used Valves... Feb 28 16:05:05 "empty state technology" Feb 28 16:05:29 KotH, what are you designing (if you can say)? Feb 28 16:05:48 probably some kind of weapon Feb 28 16:06:01 ka6sox: rubidium based frequency normal based on coherent population trapping ;) Feb 28 16:06:23 "swiss madman builds phaser from off-the-shelf parts" Feb 28 16:06:52 ka6sox: basically: two lasers shot into a rubidium vapor cell with an offset of 6.9GHz to each other and a photodiode to detect the absorption Feb 28 16:07:03 Amtrak considers a 120mm pipecutter a "Weapon" Feb 28 16:07:05 ka6sox: the problem is to get to the 6.9GHz offset Feb 28 16:07:55 when the tsa people asked if I had anything dangerous in my bag, I said "does dirty underwear count?" Feb 28 16:07:58 KotH, you are going to "tune" the lasers with what? Feb 28 16:08:31 mru, and you weren't separated out for "special treatment"? Feb 28 16:08:44 that had already happened Feb 28 16:09:17 I don't remember if it was before or after they detected explosives Feb 28 16:09:27 ka6sox: currently i see 3 ways to do that: 1) modulation of a VCSEL with 3GHz (problem: doesnt work well together with an external cavity), 2) detection of the beat frequency of two lasers with an avalanche photodiode (problem: i cannot find any diode specified for that signal frequency range around 780nm) or 3) use a third, pulsed laser and the non linear effect of two photon absorbtion in a laser diode to get a correlation between the pulse train and Feb 28 16:10:21 morning friends, trolls, and the overlap on the venn diagram Feb 28 16:10:35 you have non-troll friends? Feb 28 16:10:41 greetings friendly guy with the giger counter Feb 28 16:10:49 geiger* Feb 28 16:11:25 KotH, Kerr Cell mixing? Feb 28 16:11:53 or is that too slow?

Feb 28 16:11:55 one alien hahaha, two alien hahaha, three alien hahaha Feb 28 16:12:10 KotH: since you're not on g+ I guess you missed my tsa story... Feb 28 16:12:20 mru: i missed it :) Feb 28 16:12:33 ka6sox: but EOM are supposed to get into that frequency range Feb 28 16:12:57 ka6sox: but these are so horribly expensive i could buy myself a cs beam frequency standard for that money Feb 28 16:13:01 KotH: I got pulled over for a random check during which they "detected" traces of explosives Feb 28 16:13:08 mru: what? Feb 28 16:13:22 took me quite by surprise Feb 28 16:13:34 so they did a _very_ thorough search of my bags Feb 28 16:13:36 mru: let me guess, you had still bits of swiss chocolate on your bag? Feb 28 16:13:59 by thorough I mean they removed the credit cards from my wallet Feb 28 16:14:06 ouch Feb 28 16:14:19 they put it all back just like it was though Feb 28 16:14:43 KotH: does a giger counter count the giggities of glenn quagmire? Feb 28 16:14:57 then they did a second patdown, slightly more thorough than the first Feb 28 16:15:01 then they let me go Feb 28 16:15:32 jackmitchell: that happens when a german speaking guy writes too much english all day long :) Feb 28 16:15:41 mru: eh... Feb 28 16:15:52 mru: isnt the tsa a very nice organization? Feb 28 16:16:05 these ones were quite friendly Feb 28 16:16:16 modulo the credit cards Feb 28 16:16:17 KotH, you havent' been here have you... Feb 28 16:16:26 ka6sox: i stay away from the us Feb 28 16:16:32 KotH: that wasn't unfriendly Feb 28 16:16:35 just thorough Feb 28 16:16:39 she put them back Feb 28 16:16:42 in the right order Feb 28 16:16:43 okay Gents (and trolls)...about to go underground for a bit. Feb 28 16:16:44 ah.. Feb 28 16:16:49 mru: thought they took them.. Feb 28 16:17:03 ka6sox: going trough hell? ;) Feb 28 16:17:05 that would've been rude Feb 28 16:17:25 no, just thru the mountains Feb 28 16:17:41 (and you thought only the Swiss could do that....) Feb 28 16:17:53 ka6sox: no, the swiss just do it a lot more then other people Feb 28 16:18:07 KotH, true... Feb 28 16:18:08 and the norwegians Feb 28 16:18:37 ka6sox: i still wish they'd build the swissmetro Feb 28 16:18:53 ka6sox: a county wide high speed railway system, completely underground Feb 28 16:18:58 country* Feb 28 16:19:20 ka6sox: i guess you have no idea for my laser problem ? Feb 28 16:19:52 KotH, I am not a Laser Guy...RF Guy...yes... Feb 28 16:19:58 root@beaglebone:~# uname -a Feb 28 16:19:59 Linux beaglebone 3.8.1 #136 SMP Thu Feb 28 17:01:01 CET 2013 armv7l GNU/Linux Feb 28 16:20:22 koenkooi, but with NO audio right? Feb 28 16:20:30 ka6sox: the problem is RF not laser :) Feb 28 16:20:41 ka6sox: audio should work on the dvi+audio cape Feb 28 16:20:47 ka6sox: the laser part is well documented Feb 28 16:20:59 koenkooi, then where do I get one? Feb 28 16:21:24 ka6sox: just an idea for sub-ns pulses with a >100MHz repetition rate would be enough :) Feb 28 16:21:46 KotH, perhaps when I get to the other side. Feb 28 16:22:25 ka6sox: the audio setup between dvi+audio and the voldemort bone is very different Feb 28 16:22:30 ka6sox: ok Feb 28 16:22:51 ah...okay Feb 28 16:23:09 mcasp isn't very friendly. Feb 28 16:23:38 ka6sox: my current idea is to use a fmmt415 avalanche transistor. but the specs for it are rather slimm. so i would need to build a test circuit. unfortunately, i dont have the equipment to supply it with teh 200V it needs, i'd have to build that as well Feb 28 16:24:10 the Kerr cell needs 30kV Feb 28 16:24:21 oh.. kay... Feb 28 16:24:22 bbiaw Feb 28 16:24:25 have fun Feb 28 16:24:29 ka6sox: I wouldn't expect an interface named after a happy meal to work Feb 28 16:24:53 koenkooi, its a Scottish Snake. Feb 28 16:24:55 koenkooi: still using old ultrasparcs? :) Feb 28 16:25:03 Sorry....Irish. Feb 28 16:25:13 I had a sunhme ethernet card once Feb 28 16:25:16 worked like a charm Feb 28 16:25:27 sun hardware wasnt bad Feb 28 16:25:42 This is like Thomas the Tank Engine... Feb 28 16:26:06 afraid of going into a tunnel? Feb 28 16:26:14 wish me LUck! Feb 28 16:26:26 there's no such thing as luck Feb 28 16:26:35 only probability! Feb 28 16:26:39 KotH: no, I got rid of them, so no happy meal eth for me Feb 28 16:26:41 things happen, or they don't Feb 28 16:27:14 koenkooi: please don't say that name! Feb 28 16:27:36 mdp: huh? Feb 28 16:28:26 ka6sox: indeed, the dvi+audio setup is pretty trivial and the SoS as has been riding around on various EVMs with aic codecs for years..so it is a no-brainer at least Feb 28 16:28:53 mru, V* bone comment above Feb 28 16:29:08 mru: you mean like the guy who sued CERN for endangering the world, who when asked for the probability of creating a black hole at CERN is answered: "50%, it either happens or does not" Feb 28 16:29:58 mdp, okay so not fair comparison Feb 28 16:30:24 KotH: if you do X, Y happens Feb 28 16:30:43 Y may not always be known, but there is no such thing as 'luck' involved in determining it Feb 28 16:30:46 mru, oh....so you are a cause/effect man...got it. Feb 28 16:31:07 did you ever see one without the other? Feb 28 16:31:18 okay on the Set of ST:Insurrection. Feb 28 16:31:20 ka6sox: yeah, analog pb/cap on 2 channels is about is trivial as it gets on that cape..and most evms Feb 28 16:31:27 mru: well.. applying quatum physics, there is indeed luck... or at least probabilities for something to happen or not Feb 28 16:31:40 probability != luck Feb 28 16:32:08 luck is just a more poetic word for probability Feb 28 16:32:30 speaking of luck _after_ an event is just ridiculous Feb 28 16:32:37 Schroedinger's Cat is *still* dead. Feb 28 16:32:53 survived being underground Feb 28 16:33:11 must be a troll Feb 28 16:34:44 koenkooi, when you say the TDA is in "pcm mode" you mean iis instead of SPDIF? Feb 28 16:37:05 mru, trying to be a "little" on topic... Feb 28 16:37:15 oh...you mean surviving being underground...got it...(need more coffee) Feb 28 16:40:04 coffee, good idea Feb 28 16:40:17 * KotH goes home to contemplate more on his problem how to build a phaser from off-the-shelf components Feb 28 16:40:46 you have such easy problems... Feb 28 16:41:57 yeah.. i always get the easy stuff Feb 28 16:47:13 KotH, enjoy working with Class 1 weapons. Feb 28 16:48:12 damned...thought that the G-IV was going to land on *top* of us... Feb 28 16:53:02 ALSA_DEBUG is set Feb 28 16:53:07 ka6sox: the monitor says "1280x720 16:9 PCM" Feb 28 16:53:26 ka6sox: so the tda is in some form of audio mode Feb 28 16:53:35 of course the mcasp is doing nothing Feb 28 16:54:03 okay...thats helpful... Feb 28 17:02:52 * mru curses TI installers Feb 28 17:04:13 CCS? Feb 28 17:04:17 bleh...I hate debug kernels...too chatty. Feb 28 17:04:22 mdp: that and others Feb 28 17:04:28 sifting thru this is going to take a LONG time :P Feb 28 17:04:37 they spew files all over the place and refuse to run in a sandbox Feb 28 17:04:50 ka6sox, I hate debug u-boots...too chatty ;) Feb 28 17:05:02 * mru hates Feb 28 17:05:29 mdp, if this was easy it would be done right? Feb 28 17:05:42 if it was a priority, it would be done Feb 28 17:06:02 but yes, it's also "different" Feb 28 17:06:22 "Beautiful Downtown Burbank" Feb 28 17:06:49 mcasp is extremely flexible..and as you see...the kernel driver makes assumptions due to what has been historically hooked up to it and how Feb 28 17:08:09 there is another word I use for things that are too "flexible"...Convoluted :P Feb 28 17:08:48 convolutions can be simplified using an fft Feb 28 17:14:02 20 more minutes on the "choo choo" then RL takes over :9 Feb 28 17:17:07 ka6sox: where you going Feb 28 17:17:09 ? Feb 28 17:38:46 ka6sox: you said something about striplines... what do you mean exactly by that? (i know what striplines are) and how do they help in generating a short pulses? Feb 28 18:35:09 * mranostay enjoys passive-agressive jkridner Feb 28 18:35:20 :) Feb 28 18:39:42 jkridner: they seemed to be lacking professional embedded linux engineers Feb 28 18:45:00 then again they were cheap Feb 28 18:45:11 that whole linux thing ain't so hard after all Feb 28 18:50:05 w00t! Feb 28 18:50:09 low cost like RPi Feb 28 18:50:37 easy match in a keyword search for resources Feb 28 18:51:29 panto: btw got JTAG working again.. seems solder popped off one of the CTI pins Feb 28 19:10:44 * mranostay pokes mru Feb 28 19:11:00 * mru shrugs Feb 28 19:17:28 * mdp completes task and catches up on the funny thread Feb 28 19:19:15 SNR is plummeting on that list Feb 28 19:19:37 mranostay: pokes Feb 28 19:40:49 mranostay: morning? Feb 28 19:41:12 closer to noon over there, no? Feb 28 19:41:30 still technically morning Feb 28 19:41:51 when did you wake up? Feb 28 19:42:08 i spent a lot of time reading the PRU doco last night Feb 28 19:42:13 hows that for fun Feb 28 19:46:33 mranostay: those "pulsed" outputs from the PRU, are they just PRU system events Feb 28 19:47:18 i'm looking at some code and the output of the PRU with a scope and i'm not seeing teh pulses Feb 28 19:47:37 im seeing GPIO that looks like ordinary PRU Feb 28 19:47:46 ordinary GPIO i mean Feb 28 19:56:12 mrpackethead: you have it muxed correctly? :) Feb 28 19:56:44 well, i'm just running this code Feb 28 19:56:46 basically r30 is GPI and r31 is GPO Feb 28 19:56:53 then no :) Feb 28 19:57:00 but the output is correct Feb 28 19:57:04 its not pulsing Feb 28 19:57:13 and theres no flipflop Feb 28 19:57:16 what code? Feb 28 19:57:37 https://github.com/boxysean/beaglebone-DMX/blob/master/src/dmx.p Feb 28 19:58:34 ew Feb 28 19:58:42 he is using GPIOs directly Feb 28 19:59:11 * mranostay probes mdp for the code shaming Feb 28 19:59:30 not sure why that woudl be considered bad? Feb 28 19:59:54 well it is non-determistic Feb 28 20:00:24 given (a) it works and (b) it does'nt require any external hardware Feb 28 20:01:01 work is such a vague notion Feb 28 20:01:26 mru: the 'thing' produces an output that is acceptable as DMX Feb 28 20:03:45 mranostay: in this code, does the PRU not actually Set the GPIO directly, and passes that back to the main CPU? Feb 28 20:05:22 <_av500_> gm Feb 28 20:07:41 Hmmmm Feb 28 20:08:01 it is writing to the GPIO memory mapped registers Feb 28 20:08:07 yes Feb 28 20:08:17 over L3? Feb 28 20:09:34 * mrpackethead thinks hes about to learn something there Feb 28 20:10:41 you drop clock cycles everytime to write to memory outside of the PRU Feb 28 20:10:57 an unknown number of cycles Feb 28 20:11:05 since you might have to wait for the bus Feb 28 20:11:06 mranostay, that's the one I previously cited as The Wrong Way(tm) Feb 28 20:11:24 mdp: so that's the one everbody copies Feb 28 20:11:40 mru, I'm sure they do Feb 28 20:11:47 people are remarkably good at singling out the worst example and copying that Feb 28 20:12:14 mru: i remember a doc on this though . PRU reference manual? that put it as a few hundred cycles Feb 28 20:12:20 mru: are you saying we can crowd source wrong answers to eliminate them? :D Feb 28 20:12:44 so, in many ways, what this code is doign is copying some data from user space, implementing a timer, and then dumping it back to the CPU to set the i/o Feb 28 20:13:16 mranostay: I don't remember a figure, but I can imagine it being potentially quite a few cycles Feb 28 20:13:28 well userspace should be copying into the PRUs DRAM Feb 28 20:13:38 the pru has dram? Feb 28 20:13:40 SRAM Feb 28 20:13:45 mranostay: btw, have you look at using semiconductor sensors in place of your tubes? Feb 28 20:13:47 yes yes SRAM Feb 28 20:13:54 #exactwords Feb 28 20:14:21 ds2: nope Feb 28 20:14:27 would i be right in assuming that things could get worse timing wise as your CPU gets busier? Feb 28 20:14:41 mranostay: supposely PIN diode are quite sensitive Feb 28 20:14:48 mrpackethead: s/CPU/SoC/ Feb 28 20:15:03 ok,, SoC Feb 28 20:15:22 ds2: PIN diode, is that what they use on bank cards? Feb 28 20:15:24 mrpackethead: all you need is some serious traffic on the interconnect Feb 28 20:15:37 mru: could be ;) Feb 28 20:15:40 the L3 interconnect Feb 28 20:15:41 esp if you have a 2 way one Feb 28 20:15:42 ? Feb 28 20:17:20 mrpackethead: yes, L3F in AM335x's case Feb 28 20:19:14 Lyren Brown's Atari expansion port project explains the real world consequences of trying to do stuff out on the interrconnect with PRU Feb 28 20:19:39 just in case you wonder if we are just running a grad course here ;) Feb 28 20:19:53 mdp: linky poo? Feb 28 20:20:20 https://github.com/lybrown/abx Feb 28 20:21:05 mranostay: I tried to be a smart ass and find a chain made with links of poo. After all these years, I've found something that doesn't exist on the internet. Feb 28 20:21:17 I think I can disconnect now. Feb 28 20:21:21 I have won. Feb 28 20:21:29 er ok Feb 28 20:22:03 mranostay, there's comments in his notes about how he ran into theory when trying to work with DRAM, couldn't meet the deadlines to decode 65xx bus cycles Feb 28 20:22:30 mranostay: for your nixie tube thing, how did you use the PRU I/O? Feb 28 20:22:54 <_av500_> bit banged Feb 28 20:23:00 noobish: did you check on etsy? Feb 28 20:23:04 mrpackethead: r30/r31 Feb 28 20:23:41 * _av500_ is loaded with small EVMs Feb 28 20:24:10 _av500_ / mdp.. bitbanging is fine.. however from what iv'e been told the ouputs are just pulses and they don't stay in a steady state Feb 28 20:24:20 mrpackethead: another example of native PRU GPO/GPI use: https://github.com/ohporter/b6502/blob/master/pruss/b6502_pruss.p Feb 28 20:24:22 is my understanding correct? Feb 28 20:24:30 no, outputs stay. Feb 28 20:24:34 mrpackethead: no Feb 28 20:24:35 https://github.com/mranostay/beagle-nixie/blob/master/standalone_clock/pru0_clock.p Feb 28 20:24:53 ok.. because that had me very very confused Feb 28 20:25:01 mrpackethead: sounds like you are thinking of PRUSS "events" Feb 28 20:25:17 which are like other "events" in the SoC Feb 28 20:25:40 do you know of any good event examples? Feb 28 20:26:00 mmm... Feb 28 20:26:11 noobish: nixie clock :) Feb 28 20:26:39 sweet! i'll take a look. Feb 28 20:27:09 mdp: steady state are you sure? :) Feb 28 20:27:48 i had an led here blinking very slow with the pru last week. Feb 28 20:27:55 err...shit...last month. Feb 28 20:28:04 noobish: using GPIOs? Feb 28 20:28:17 mrpackethead: 4.5.2.2.3 and 4.5.2.2.3.4 in spruh73c.pdf Feb 28 20:28:37 pru gpios Feb 28 20:29:39 mranostay, do you use events other than 0? I'm looking for an example of the higher events. Feb 28 20:31:17 mdp: ah shift out mode? Feb 28 20:31:38 direct is the default Feb 28 20:31:46 lots of options Feb 28 20:33:40 mranostay, dueling github pruss projects ;) Feb 28 20:33:59 mranostay, both doing weird stuff Feb 28 20:34:03 mdp: have you got a link to spruh73c.pdf Feb 28 20:34:11 google, it's cached Feb 28 20:34:12 i have spurh73g.pdf Feb 28 20:34:24 and its missing most of chapter 4 Feb 28 20:34:26 logging is on here..I can't give a link ;) Feb 28 20:34:35 rodger Feb 28 20:34:55 perhaps somebody else can send a link to the forbidden fruit Feb 28 20:35:04 heh Feb 28 20:37:30 oh, and fwiw, Lyren's comments were on the list: https://groups.google.com/forum/?fromgroups=#!topic/beagleboard/NF8zKl29HYk Feb 28 20:38:55 never delete old versions of a trm Feb 28 20:39:20 wonder if there is someway to prove it was released as a TRM Feb 28 20:39:56 mru, this is true even if you work for TI ;) Feb 28 20:40:20 never delete anything Feb 28 20:40:25 <_av500_> ds2: yes, get the md5sum of it into the bitcoin hash chain Feb 28 20:40:28 that's true everywhere Feb 28 20:40:48 <_av500_> old rule, before you delete anything, make a copy Feb 28 20:40:58 if it was, it would be nifty to point out it has been "publish" and this NDA no longer apply Feb 28 20:42:26 _av500_ deleted it from the internets Feb 28 20:43:39 Can anyone explain about the motor addon for beaglebone? Feb 28 20:43:39 * mranostay emails evil trm Feb 28 20:44:13 mranostay, Are We Evil? Feb 28 20:48:11 afk for a bit Feb 28 20:52:30 wait, was the pru reference guide pulled or something? Feb 28 21:05:11 it should in an addendum/appendix, from what I been told Feb 28 21:07:53 anyway i have version c, which was easily downloadable fro 'dubious.ru' Feb 28 21:13:12 so, mru.. its 'direct' mode we want Feb 28 21:13:21 to get so called 'stable' operation Feb 28 21:26:35 were you using "shift out" mode before? Feb 28 21:26:54 still lost as to where you heard about "pulse outputs" Feb 28 21:28:16 mdp: oh, it was one of the trolls who hangs around here Feb 28 21:28:29 darn trolls Feb 28 21:28:40 trolls? no trolls here. we're all professionals. Feb 28 21:28:54 hes a useful troll though, so we won't subject him to the ridicule. Feb 28 21:29:08 * bradfa runs from trolls Feb 28 21:29:19 trolls chase him Feb 28 21:29:28 gahhh! Feb 28 21:29:29 bradfa: are you a hobbit Feb 28 21:29:35 hobbits run from trolls Feb 28 21:29:47 mrpackethead, I think I'm a bit tall to be a hobbit... Feb 28 21:29:54 or pick their pocketeses. Feb 28 21:30:13 smegal is not a troll Feb 28 21:30:26 shall we play a game Feb 28 21:30:30 if you lose, i'll eat you Feb 28 21:30:43 bilbo picked the talking purse from the pockets of the trolls by the fire. Feb 28 21:31:54 <_av500_> bradfa: why not a BBB? Feb 28 21:32:17 <_av500_> can your M3/4 even handle the high speed usb stuff? Feb 28 21:32:27 <_av500_> what are you going to do with all that data? Feb 28 21:32:43 _av500_, make an SD card reader Feb 28 21:32:59 <_av500_> thts a ... novelty Feb 28 21:33:02 yes Feb 28 21:33:08 this is good Feb 28 21:33:10 but will teach me quite a lot about SD / MMC and USB Feb 28 21:33:12 <_av500_> I'd buy one Feb 28 21:33:22 i'm feeling much happier about being able to tackle a project now Feb 28 21:33:31 BOM cost is like $10 in low quantities for the chips, assuming I can find an M3 to dev on Feb 28 21:33:35 3d print a case Feb 28 21:33:43 Linux driver for mmcblk device Feb 28 21:33:57 I hate laptops but want to have mmcblk devices on my computer Feb 28 21:34:41 mrpackethead, due to the hobbits and trolls? Feb 28 21:34:50 yes. Feb 28 21:34:52 trolls Feb 28 21:35:16 <_av500_> bradfa: but you have heard os USB sdcard readers? Feb 28 21:35:20 <_av500_> of* Feb 28 21:35:26 its section 19 of the TRU Feb 28 21:35:31 TRM even Feb 28 21:35:41 _av500_, yes, but most show up as SCSI devices Feb 28 21:35:41 spruh73t.pdf Feb 28 21:35:49 't' for troll Feb 28 21:36:15 <_av500_> bradfa: and yours would not? Feb 28 21:36:18 correct Feb 28 21:36:33 <_av500_> you want to make a shim driver Feb 28 21:36:41 <_av500_> that exposes it as mmcblk Feb 28 21:36:55 ok (I haven't really thought this through much) Feb 28 21:37:01 <_av500_> np Feb 28 21:37:08 <_av500_> I rarely so :) Feb 28 21:37:11 <_av500_> do* Feb 28 21:37:11 I know it's possible but not the details Feb 28 21:37:19 <_av500_> its SW, anything is possible Feb 28 21:37:26 ideally, extra feature would be to have SDIO via USB Feb 28 21:37:32 via my board Feb 28 21:37:40 then you could run SDIO cards on a desktop Feb 28 21:37:47 or anything with USB I guess Feb 28 21:37:55 not sure anything like that exists Feb 28 21:37:57 <_av500_> riht Feb 28 21:38:04 <_av500_> never saw that Feb 28 21:38:13 <_av500_> so you would run the SD stack on the PC Feb 28 21:38:18 <_av500_> and use USB as a tunnel Feb 28 21:38:20 NAND! Feb 28 21:38:21 basically, yes Feb 28 21:38:22 NAND! Feb 28 21:38:23 NAND! Feb 28 21:38:30 mranostay, quiet you! Feb 28 21:38:33 :) Feb 28 21:38:36 <_av500_> operator!!! Feb 28 21:39:08 NAAAAAND!!! Feb 28 21:39:30 <_av500_> NOOOOOOOOOOOOOOOOOOOOOOOOOOORRRRRR! Feb 28 21:39:33 mru, is that special memory with extra Canadianness Feb 28 21:39:34 ? Feb 28 21:39:46 eh? Feb 28 21:40:22 isn't there NAND inside the SD card? :) Feb 28 21:40:31 usually Feb 28 21:40:35 there is magic inside Feb 28 21:40:47 mdp, is that what makes the smoke? Feb 28 21:40:53 yes Feb 28 21:41:00 ok, I thought it was tiny trolls Feb 28 21:41:13 others will try to confuse you with the facts or explain it away with science Feb 28 21:41:17 but you heard it here first Feb 28 21:41:48 trolls are magic...so some SD cards have tiny trolls inside...it's implementation dependent Feb 28 21:42:08 the spec allows great latitude here Feb 28 21:42:26 mdp, ah, ok, that must be the part of the spec that requires NDA Feb 28 21:42:29 relatives of maxwell's demons? Feb 28 21:43:09 bradfa, you won't find it in the public version, no Feb 28 21:43:28 even dubious.ru doesn't carry this stuff Feb 28 21:47:35 first pru project coming up.. flash a led Feb 28 21:47:38 how exciting. Feb 28 21:47:49 in the non write to the GPIO mode Feb 28 21:47:50 :-) Feb 28 21:48:02 my first flashing LED was done with 2 transistors Feb 28 21:48:32 <_av500_> mine flashed a light bulb Feb 28 21:49:07 <_av500_> and I had only 1 transistor, so I had to multiplex it... Feb 28 21:50:17 mrpackethead: I did that project too! Feb 28 21:50:40 mrpackethead: try it the wrong way too with GPIOs, for good measure Feb 28 21:50:53 i seem to have done this project many times before Feb 28 21:51:02 every new bit of hardware Feb 28 21:51:14 *surely* we can come up with an alternative to blinking leds Feb 28 21:51:34 helloworld.c has a lot to answer for. Feb 28 21:51:40 toggle on a compressor motor? Feb 28 21:51:48 hrm, no, I think there's a reason we test with leds Feb 28 21:52:26 shotguns, we need GPIO shotguns Feb 28 21:52:38 helloworl *BANG* Feb 28 21:53:07 bitbanging indeed Feb 28 21:53:10 +1 Feb 28 21:53:26 <_av500_> assault programs Feb 28 21:53:38 nobody needs a program that powerful Feb 28 21:53:52 _av500_: with high-capacity fifos? Feb 28 21:54:12 +1 Feb 28 21:54:13 stockpile the hi-cap fifos now Feb 28 21:54:28 you'll be sorry when you have to service the i/o with no fifo Feb 28 21:54:42 got to port igmp to run with microchips TCP/IP stack Feb 28 21:54:44 that will be fun Feb 28 21:54:51 when fifos are outlawed only er ... Feb 28 21:55:30 mranostay, we can fabricate our own fifos on fpgas...we'll get around the ban! Feb 28 21:56:17 in NY you can have 10 bit FIFOs but only if you only every 7 of the bits Feb 28 21:56:36 plus grammar Feb 28 21:56:42 lots of it Feb 28 21:57:39 <_av500_> you cna only buy registered fifos Feb 28 21:58:08 <_av500_> but we need to close the open source loop hle Feb 28 21:58:10 <_av500_> hole* Feb 28 21:58:26 can dt help with that? Feb 28 22:00:33 mru, only on newer models Feb 28 22:00:48 * bradfa thinks it's beer o'clock Feb 28 22:01:07 damn, no beer in fridge Feb 28 22:01:21 bradfa, you are correct sir! Feb 28 22:01:33 cya, trolls! Feb 28 22:01:49 then again, it's probably a good idea to limit beer intake in the week between conferences Feb 28 22:13:14 Bus 002 Device 039: ID 0b1e:0009 Electronic Warfare Assoc., Inc. (EWA) Feb 28 22:37:54 prpplague: have the rum open yet? :) Feb 28 22:38:24 <_av500_> it is ever closed? Feb 28 22:49:11 mranostay: just opened the beer Feb 28 22:49:18 * prpplague is totally stressin Feb 28 22:55:00 everyone group hug prpplague now Feb 28 22:55:14 * prpplague backs away Feb 28 22:56:04 i really hate leaving a project unfinished Feb 28 22:57:40 prpplague: OCD? :) Feb 28 23:00:18 prpplague: pandaborad.org should cheer you up Feb 28 23:00:53 indeed Feb 28 23:02:01 * _av500_ listens up Feb 28 23:02:07 <_av500_> do you want it more cheerie? Feb 28 23:02:34 <_av500_> cowbells? Feb 28 23:02:41 <_av500_> taco bells? Feb 28 23:02:46 <_av500_> tinkerbells? Feb 28 23:02:53 <_av500_> hells bells? Feb 28 23:03:06 <_av500_> impossibells? Feb 28 23:03:24 <_av500_> or les miserabells? Feb 28 23:07:58 _av500_: Those puns are horribell. Feb 28 23:10:40 prpplague: can i have an empty bottle? Feb 28 23:11:01 mranostay: sure Feb 28 23:11:19 * mranostay hits _av500_ over the head with it Feb 28 23:19:03 * NishanthMenon wanders around doing make htmldocs and fixing warnings Feb 28 23:19:49 * mru imagines killing someone responsible for ccs in elaborate ways Feb 28 23:20:34 * NishanthMenon knows the guy Feb 28 23:29:29 NishanthMenon: you just think you know people Feb 28 23:29:42 prpplague, that is true as well :( Feb 28 23:30:02 hmmmm Feb 28 23:48:04 prpplague: if you assume everybody will stab you in the back first chance they get, you won't be too far off Feb 28 23:48:19 hehe Feb 28 23:48:40 or at any rate you'll (hopefully) be ready for it when they do Mar 01 00:03:32 mru, there's too many people responsible for it to possibly get them all Mar 01 00:03:44 mru, you'll have to be satisfied with one or just a few Mar 01 00:04:12 I could nuke the dallas from orbit... Mar 01 00:04:20 -the Mar 01 00:04:25 my fix for CCS is similar to how I deal with USB Mar 01 00:04:44 mru, hrm, I suspect you'll need to take out Bangalore as well Mar 01 00:04:55 all I want to do is flash a damn evm Mar 01 00:05:12 your new toy? Mar 01 00:05:15 yeah Mar 01 00:06:25 following the exact steps gives me two pages of error messages Mar 01 00:06:39 starting with something about an invalid processor id Mar 01 00:07:00 if it told me _what_ the invalid thing was and _where_ it was encountered, maybe I'd be able to figure out what I did wrong... Mar 01 00:07:08 but that would be too easy Mar 01 00:12:49 mdp: so what's your fix for ccs? run for the hills whenever it's mentioned? Mar 01 00:24:44 heh Mar 01 00:29:56 mdp, houston, we have a problem? Mar 01 00:32:16 NishanthMenon: Don't you mean Dallas? :P Mar 01 00:32:34 mranostay, :D Mar 01 00:32:44 mranostay, dont like nukes in dallas ;) Mar 01 00:46:30 Woot! Got uio_pruss working with event 2! Mar 01 00:54:26 mru, correct Mar 01 00:54:34 mru, I don't use it Mar 01 00:54:41 mru: https://lh6.googleusercontent.com/-gQvaY83ng9s/US_67znMn-I/AAAAAAABjKo/l-v3-6Dv4NI/s500/IMG_0826.JPG Mar 01 00:54:53 lol. Mar 01 00:55:10 quite Mar 01 00:55:30 noobish cool! Mar 01 00:55:59 NishanthMenon, we're working hard to keep nukes out of mru's hands Mar 01 00:56:22 KotH: how are those phasers coming along? Mar 01 00:56:43 can you also make some photon torpedoes while at it? Mar 01 00:56:53 * mdp watches patman fail repeatedly Mar 01 00:57:01 hey take it easy on nishanth, he's now "OMAP5-Man" Mar 01 00:57:37 prpplague: oh, I need him to point out the targets Mar 01 00:57:57 * prpplague works hard not to make further jokes with the special power of "OMAP5-Man" Mar 01 00:59:52 like the special power to be invisible in public? Mar 01 00:59:59 he wears the ring! Mar 01 01:00:05 prpplague: jokes are good Mar 01 01:00:14 they're the only thing making reality tolerable Mar 01 01:00:17 long love OMAP5! Mar 01 01:00:26 and i.mx7! Mar 01 01:00:57 mru: hehe Mar 01 01:01:11 mru: like creating massive driver support from thin air and no resources Mar 01 01:01:29 what did you think drivers were made of? Mar 01 01:01:54 mru: hey according to management it's all one and zeros , how hard could that be? Mar 01 01:02:08 prpplague: You left early today.. Could not catch you to say goodbye.. :-( Mar 01 01:03:15 Jayneil: yea i know Mar 01 01:03:26 Jayneil: i am not into that kind of stuff Mar 01 01:03:31 * prpplague sneaked out Mar 01 01:03:43 Jayneil: not like we aren't friends and will talk another time Mar 01 01:04:01 prpplague: ha ha.. sure thing.. :-) Mar 01 01:04:24 mru, at least they have some truthiness in that…mgmt on the ball! Mar 01 01:05:24 * mdp shelves patman for another day Mar 01 01:06:07 bam, so now i have one pru mdio bit banging, and the other jtag bit banging. Mar 01 01:06:09 Jayneil: the whole thing today has me a little upset, so it is a good thing i left quietly Mar 01 01:06:29 this is getting easier! Mar 01 01:06:36 except the makefiles...makefiles are still hard. Mar 01 01:06:42 PRU_EVTOUT_2: yea, but can you do a pwm led like they do with the RPi? Mar 01 01:06:48 nothing is easier than makesfiles Mar 01 01:06:56 once you understand how they really work Mar 01 01:06:58 you seem to have it internets connecged too! getting your events on #beagle ! Mar 01 01:07:23 prplague: unfortunately not. i only know how to wiggle io pins in irregular patterns :-\ Mar 01 01:07:32 prpplague: beaglebone can't do anything that RPi can Mar 01 01:07:39 prpplague: I totally understand.. Mar 01 01:07:47 mdp: i know, disgusting isn't it Mar 01 01:08:00 how'd you know i have it internet connected? are you a wizard? Mar 01 01:08:08 PRU_EVTOUT_2: you even have your very own ecap block inside the PRUSS…don't have to bit bang for pwm Mar 01 01:08:10 mdp: it can't even drop ethernet packets! Mar 01 01:08:18 and don't have to go out on the l3 to get at it Mar 01 01:08:24 it makes such a horrible doorstop Mar 01 01:08:28 mru, it is a complete disappointment Mar 01 01:09:05 i think the whole concept of a pru, and TWO of them, is really friggin cool. Mar 01 01:09:17 good on you ti. Mar 01 01:09:49 would be cooler if it was like a M0, R0 or even a MSP430 Mar 01 01:09:56 why? Mar 01 01:10:16 less toolchains to deal with Mar 01 01:10:26 M0 seems quite annoying actually Mar 01 01:10:37 what's your gripe on the M0? Mar 01 01:10:44 thumb1 instruction set only Mar 01 01:11:08 with a handful of additions for exception handling and such Mar 01 01:11:10 thought thumb1 didn't have the system stuff? Mar 01 01:11:15 Ohh additions Mar 01 01:11:18 ds2, an assembler for the pru is hardly in the class of a "toolchain" in the sense that we are used to dealing with complex failures in the big ones Mar 01 01:11:20 not much system to speak of on m0 Mar 01 01:11:34 for a moment, I thought they also have ARM32 implemented partially ;) Mar 01 01:11:40 ds2, for the most part…it's about as KISS as you can get on a modern part today Mar 01 01:11:57 mdp: a MSP430 would fit that bill just as well Mar 01 01:12:04 at 200mhz? Mar 01 01:12:10 why not? :D Mar 01 01:12:15 yeah Mar 01 01:12:25 the pru instruction set is simple enough you could write it directly in hex Mar 01 01:12:26 not my miracle to perform Mar 01 01:12:36 mru, nobody does that! Mar 01 01:12:38 ;) Mar 01 01:12:40 no toolchain required Mar 01 01:13:08 afterall, they do have 1GHz 8051's Mar 01 01:13:18 it's tempting to do it and watch the freetards scream for the source code Mar 01 01:13:39 obfuscated pru contest time Mar 01 01:14:09 speaking of obfuscation, is it possible to make the edma reprogram itself? Mar 01 01:14:29 by directing a transfer at its own registers Mar 01 01:14:41 is it turing complete? Mar 01 01:14:52 I don't know Mar 01 01:15:10 sounds like a project and a presentation Mar 01 01:15:22 running malware undetected in the dma engine Mar 01 01:15:27 new meaning to run away DMA engine Mar 01 01:33:42 mru, interesting concept…seems possible to perform a transfer into PaRAM and the registers to kick a transfer Mar 01 01:42:07 Russ, needs a bitbanging angle for a proper presentation Mar 01 01:51:36 bitbang! Mar 01 02:02:06 ' Mar 01 02:06:23 ds2: bitbang NAND! Mar 01 02:15:48 prpplague: what is with some slides being posted and others not on the ELC site? Mar 01 02:16:04 i notice me and you are the few that don't have any Mar 01 02:16:32 mranostay: no clue Mar 01 02:16:40 mranostay: you submitted a pdf with your slides? Mar 01 02:16:51 yeah on time and all :P Mar 01 02:18:07 prpplague: maybe we are special Mar 01 02:18:28 and I think their photographer quit sometime during the morning of the 21st Mar 01 02:18:33 mranostay: i'll check on it tomorrow Mar 01 02:18:42 same with whoever was making the videos Mar 01 02:19:19 heh Mar 01 02:19:39 Russ: Sarcasm? :) Mar 01 02:19:53 yeah i noticed a gap in pictures Mar 01 02:20:04 ya, they just haven't uploaded anything beyond the morning of the 21st yet Mar 01 02:20:20 and not all of the 20th even Mar 01 02:20:43 a few of the talks are dated the 21th Mar 01 02:59:07 ok this next gen bone... will it be pin-compatible with the current gen bone?
