**** BEGIN LOGGING AT Mon Apr 13 02:59:57 2020 Apr 13 03:01:30 what you know can confuse you and everyone around you. :D Apr 13 03:25:23 lol Apr 13 03:30:40 Zanzabar! Apr 13 16:38:23 i hope you folks don't mind an off-topic question. this is for zmatt, and this is the only place i know to get ahold of him. Apr 13 16:38:36 are secure monitor calls (SMC) on a multi-core processor handled by each core individually? Apr 13 16:39:45 related, does each core have its own secure monitor interrupt vector base address register? Apr 13 16:49:57 i am specifically using a Cortex A9, but this applies to other v7 and v8 cores, i believe Apr 13 16:50:01 mpcores Apr 13 17:01:20 Hi everyone. I could use some help. I have a beaglebone black and I am running the latest image debian 10 from the getting-started website for beaglebone. I am writing some python code. I want to hook some limit switches up for a robot I am programming. Currently I am using the Adafruit_BBIO library. When setting most GPIO up as an input I get this Apr 13 17:01:20 error: Apr 13 17:01:23 SystemError: returned NULL without setting an error Apr 13 17:01:44 I have changed nothing but the pin and gotten some gpio to work so I know its a configuration issue Apr 13 17:02:24 I used the show-pins utiliy from github and I don't see the hi >> part for the gpio I would like to use. How can I configure these to be inputs on boot? Apr 13 17:22:01 I'm guessing it requires another custom overlay.. Apr 13 17:23:44 James8797 I assume you are using python? Apr 13 17:36:16 yates_home zmatt has yet to speak up in the last 12 hours his last was at ~05:30 his time and 23:30 EST US time. Apr 13 17:56:43 I am GenTooMan Apr 13 18:16:52 GenTooMan: i hope he's ok - maybe took an extra day for Easter weekend? Apr 13 18:30:27 James8797 The issue with Adafruit BBIO is that they changed it. It's deprecated. I also had to install some things to support SPI. They have a general purpose IO thing they wrote in python now. Apr 13 18:31:08 yates_home he laughed at something said at 23:25:23 on April 12 my time so ... I think so? :D Apr 13 18:43:56 James8797 well specifically the BBIO if you look at the github status it's been updated. What's installed on the BBB circa 2019_09 is the deprecated library. I would examine https://github.com/adafruit/adafruit-beaglebone-io-python and attempt to install that specific library. I know I had problems when I tried to use it like you described. Apr 13 19:24:59 GenTooMan: he never laughs at my jokes... pfft! Apr 13 20:09:48 GenTooMan: irc has audio? Apr 13 20:22:35 nah just an LOL but hey he's likely OK Apr 13 22:42:07 So, when is the setup for mr. jason teaching the world? I want in! Apr 13 22:42:20 I saw the blog and a post on google groups. Apr 13 22:42:54 I want to learn things, man. I cannot sit idle and do nothing. Apr 13 22:52:00 I know things take time. I think this idea would be nice for people like me who have little administration exp. in Linux but find it fun to work w/ as of now. Apr 13 22:52:47 For example: The pandemic is still around, pray for all souls, and sitting inside has become second nature for me these days. Apr 13 22:53:11 Selfish, maybe. A tempting learning experience, yes. Apr 13 22:54:25 I have some books and tried to sign up for a Linux LPIC-1 exam but the dang Linux people only allow for so much time before they cancel their/my membership status. Argh. Apr 13 22:54:50 Anyway, that is all. Apr 13 23:12:44 good to hear.. the real issue at the moment is things are changing and college grads are a bit dangerous these days. Apr 13 23:50:36 What? Apr 13 23:50:40 Dangerous? Apr 13 23:50:45 Like w/ sticks and stones? Apr 14 00:00:14 or... Apr 14 00:00:31 Are people just bringing their prickiness w/ them? Apr 14 00:36:16 whats the difference between a source file and class file in c++ Apr 14 00:39:20 nm Apr 14 00:40:56 Hmm. Apr 14 00:40:59 Source. Apr 14 00:41:38 MattB0ne: Are people losing their humanity about the BBB around you? Apr 14 00:42:02 I am asking b/c GenTooMan said something disturbing to me earlier. Apr 14 00:43:30 Do not answer. I will take my concern elsewhere. Apr 14 00:43:52 Does this platform support BELA? Apr 14 00:46:02 platform = in here Apr 14 01:05:58 hi... where can I find documentation that states the country of origin for the manufactured beaglebone AI boards? thanks Apr 14 01:11:21 pbean! Apr 14 01:11:22 Hello. Apr 14 01:11:32 My name is set_. Apr 14 01:11:48 Let me check online. Apr 14 01:13:48 hmm set_ when you think you can do no wrong you tend to do a lot wrong. Unfortunately people learn from mistakes not from success. :D Apr 14 01:15:51 Oh. Apr 14 01:16:11 Okay. Apr 14 01:16:25 I found that beagleboard.org was the mfg. but I could be wrong. Apr 14 01:16:58 Look on Mouser.com or any other site that sells them. Apr 14 01:17:21 it says, mfg. w/ beagleboard.org besides it. Apr 14 01:17:33 I will check some more. Apr 14 01:18:14 set_ no I don't think beagleboard.org is the manufacturer. CircuitCo was originally. Apr 14 01:18:53 Oh. Apr 14 01:18:54 Okay. Apr 14 01:20:41 I am sorry but those mfg. that make boards have a hard time. Knowledge preceeds ability and in times when community, looking back, and bucking the system are present, "The Big Kahuna" reigns. Apr 14 01:20:49 Just saying stuff. Sorry. Apr 14 01:22:14 knowing the actual manufacturer would be wonderful. I see that the bbai wiki says country of origin is PRC. Hopefully beaglebone ai wiki is official enough for my work, they need to know before I can buy. Apr 14 01:25:39 pbean: I really do not know. I am not affiliated. Apr 14 01:25:52 I use their boards and make them work at times. Apr 14 01:25:54 But... Apr 14 01:26:16 To GenTooMan: Apr 14 01:26:35 I think even the fellow that bought a box to play w/ at times gets mad at his box. Apr 14 01:27:33 "This box is not round, this box is not rolling, etc." Apr 14 01:31:58 pbean: you should ask questions like those to the distributor. I'm pretty sure the BBAI is indeed made in china, but for example the BBB has been (or I think still is?) manufactured by different parties. so in general, just ask the distributor where you intend to buy it Apr 14 01:36:46 thank you all for the advice, information, and general replies. I appreciate it Apr 14 01:39:11 From me personally, you are welcome. Apr 14 01:40:35 I only know so much but what i do know is that people working on projects get a bad "rap." I am not saying this item to stand up or fight for justice. Mfg. is a tricky biz. Like showbiz but w/ a ton of work projected towards a part or piece of circuitry in this instance. Apr 14 01:42:14 ... Apr 14 01:43:47 For instance...mfg. in the states gets outsourced. Then, how will anyone complain or make comments? It seem reasonable to work instead of let it be. That is all. Apr 14 01:44:47 Anyway, no papers here. I just wanted to chime in and make my shtick known. Apr 14 01:50:50 I mean, if people want papers, I can provide them. I can type up some nice sba.gov stats. and other info. related to mfg. in the states for fun and all geared towards electrical, mechanical, and petroleum indices. Apr 14 01:50:53 Just let me know. Apr 14 01:53:30 ??? Apr 14 01:53:39 Look at Detroit. Apr 14 01:54:08 Look at every place that has ever held any mfg. plant or factory. Apr 14 01:54:23 All the BeagleBoards are open source. If the manufacture is unsuitable, build your own :D Apr 14 01:54:34 Beauty of Open Source Apr 14 01:54:42 Once it is gone, the entire community is in shatters, their benefits, their income, and etc. Apr 14 01:54:44 I get it. Apr 14 01:55:01 Open Source but think of mfg. in the states! Apr 14 01:55:07 The big pictorial! Apr 14 01:55:28 mfg it in your home if you don't like that Apr 14 01:55:34 Fine. Apr 14 01:55:47 I should. As soon as I figure it out. Apr 14 01:56:21 I am going to mfg. a city within my home. Apr 14 01:56:24 boy! Apr 14 01:56:35 So, what is really going on? Apr 14 01:56:57 Every Tom, Dick, and Harry are getting under your nails? Apr 14 01:58:16 But, you did it! You said it! You typed it! You, you, you! <<< This idea? Apr 14 01:59:27 Just for reference on my opinion on this subject, I have some truth telling in the form of an old story. Would anyone here like to read it? Apr 14 02:00:08 Fine! Apr 14 02:00:15 I will tell you anyway. Apr 14 02:00:16 set_ don't you have anything to do ? :D Apr 14 02:00:22 Yes. Apr 14 02:00:33 I want to tell a lesson on how I overcame adversity. Apr 14 02:00:39 It may help. Apr 14 02:00:57 Cough, so anyway. Apr 14 02:01:07 I was working while attending school. Apr 14 02:01:34 Forget it. I cannot tell this story. Apr 14 02:01:39 It is too profane. Apr 14 02:01:50 Off to find something to do. Apr 14 02:03:51 Right well I am almost finished with the display PCB so next would be to do the servo cape. Apr 14 02:03:57 What? Apr 14 02:04:03 ServoCape! Apr 14 02:04:22 GenTooMan: Are you using the PCA9685? Apr 14 02:04:35 Or a TI chip? Apr 14 02:05:00 one problem is I don't know how to export from kicad a 3d model of the board. the other is the DRC and pad clearance. Apr 14 02:05:49 Ouch. I have kiCad. Apr 14 02:06:01 export 3D model on KiCad? Apr 14 02:06:09 Did you clone it yet? Apr 14 02:06:33 Argh. Apr 14 02:06:44 Tell me what you want and I will go and get it. Apr 14 02:06:49 Right KiCAD has a 3d view and models for parts. Apr 14 02:06:55 Okay. Apr 14 02:07:15 So, you have imported the project, finished it, and now need to export it? Apr 14 02:07:19 I want to make a solid model and export that for mechanical fit (IE put the display here and how do I mount it etc.) Apr 14 02:07:40 Ouch. Again, tell me and I will listen. Apr 14 02:07:57 Order me like you were getting fries at Micky D's. Apr 14 02:08:16 i think after this COVID mess has exposed the dangers of having too much of your supply chain based in China I could see more mfg being brought home Apr 14 02:08:32 anyone here work in embedded systems professionally Apr 14 02:08:38 how do you like your job Apr 14 02:08:44 Not me but a lot of people do. Apr 14 02:08:48 Well their are all sorts of problems related to manufacturing in china Apr 14 02:09:02 well I have done so. Apr 14 02:09:02 but the MBAs only see the cost savings Apr 14 02:09:13 did you like it Apr 14 02:09:17 manufacturing is not necessarily cheaper in china Apr 14 02:09:32 the MBAs are Moronic Bastardized Administrators right? Apr 14 02:10:00 no it's not that's one of the myths.. it's highly subsidized also. Apr 14 02:10:47 it costs just as much for chinese labor as US labor. The only time when it was cheaper was decades ago. Apr 14 02:11:48 I do not hear or see any typing of orders here. Apr 14 02:12:11 GenTooMan: What do I need to do to get you to order me to solve this dilemma? Apr 14 02:12:44 logistics and supervision costs add up Apr 14 02:12:52 I am waiting for someone in KiCAD to give me a clue on DRC and 3d export. and smurfing online. Apr 14 02:13:02 Okay. Apr 14 02:13:12 Smurfing? I am off to look that one up! Apr 14 02:13:25 ds2: good point Apr 14 02:13:50 Card games? Apr 14 02:13:50 one thing I like about additive manufacturing is that you can do a lot on site Apr 14 02:14:35 header and sources files need to have the same includes Apr 14 02:14:57 MattB0ne: what are you calling additive manufacturing? Apr 14 02:15:00 seems redundant unless i am doing something wrong Apr 14 02:15:18 3D Print metals/plastics etc... Apr 14 02:15:21 Smurf me! Apr 14 02:15:53 3D printing is so limiting right now Apr 14 02:16:08 in what way Apr 14 02:16:19 3D print me optical components Apr 14 02:16:44 or something with a very fine finish Apr 14 02:16:48 well yeah but its getting there Apr 14 02:16:54 still in its infancy Apr 14 02:16:59 also that is pretty niche Apr 14 02:17:10 3D printing doesn't scale that well Apr 14 02:17:26 i will give you that Apr 14 02:17:34 if you are gonna mass produce Apr 14 02:17:38 you would not go that route b Apr 14 02:17:45 you can injection mold at home Apr 14 02:18:16 I am thinking more design to order type products Apr 14 02:18:18 not even mass production... say you need a special bracket for a robot... that can mean 30-40 pieces Apr 14 02:18:49 it comes down to materials Apr 14 02:18:56 yup Apr 14 02:19:02 but i think the future is bright Apr 14 02:19:10 trying handling PE w/3D printing Apr 14 02:19:29 money no object i would have a nice 3d printer and 5 axis CNC Apr 14 02:19:32 PE=? Apr 14 02:19:38 Polyethylene Apr 14 02:19:54 they have those bio printers Apr 14 02:20:02 i actually using one for my research Apr 14 02:20:03 Resin curing systems has started to get strong enough to be useful as well as having faster printing speed. Apr 14 02:20:08 one of those common plastics...has some nice properties like chemical resistance Apr 14 02:20:15 PEG ink Apr 14 02:20:23 not sure if that is where you are going with it Apr 14 02:23:00 Hey! Apr 14 02:23:06 I found something to do. Apr 14 02:23:42 point is 3D printing can't handle some materials and those materials can be needed in designs Apr 14 02:23:56 It had something to do w/out listening to orders from GenTooMan and the BBB. Apr 14 02:26:13 3d printing is not a panacea Apr 14 02:26:28 but it is empowering providing a lot of capability to the little guy Apr 14 02:27:58 true enough it's not a fast shift it's a steady one Apr 14 02:39:25 zmatt: are secure monitor calls (SMC) on a multi-core processor handled by each core individually? Apr 14 02:39:34 related, does each core have its own secure monitor interrupt vector base address register? Apr 14 02:47:30 yates_home: I'm fairly sure the only thing cores share is memory Apr 14 02:49:39 each core is an independent entity, with its own system registers (including MVBAR) Apr 14 02:49:47 I actually already said that last time **** ENDING LOGGING AT Tue Apr 14 02:59:57 2020
