**** BEGIN LOGGING AT Tue Apr 21 02:59:59 2020 Apr 21 03:00:01 I am trying to control these puppies w/ a BBB and some Cape. I might use one of GHI's capes. Apr 21 03:00:38 I will show you the link if you are interested. Apr 21 03:01:03 http://www.datasheetdir.com/HC126+Buffers-Drivers Apr 21 03:01:35 http://emanual.robotis.com/docs/en/dxl/ax/ax-12a/ Apr 21 03:02:48 I just ordered some TI chips, HC126 and HC04, for making a Half Duplex UART circuit for comm. to/from the BBB. Apr 21 03:02:59 Feedback! Apr 21 03:03:54 Then, I am going to use the dc-dc converter to make sure the logic level is adequate for 3.3v signals. Apr 21 03:04:29 First, the breadboard will be used. Then, who knows? Apr 21 03:04:49 I may make me another board for use if this pans out. Apr 21 03:05:00 Seen this https://www.onlogic.com/company/io-hub/tutorial-building-beaglebone-robot/ Apr 21 03:06:47 Now, I have. Apr 21 03:06:59 I made something like that before and I still keep it up to date. Apr 21 03:07:18 I have two or three bots w/ fixings. Apr 21 03:07:52 I am always in the mood for making new parts work for my bots. Time consumption really is what it boils down to for me. Apr 21 03:08:23 KenUnix: I made one of those before w/ a plate of aluminum and stainless steel. Apr 21 03:08:38 But...I never put the engine on it. Apr 21 03:08:43 I am waiting. Apr 21 03:09:06 set_cforget about that cape. I checked not made anymore Apr 21 03:09:18 What Cape? Apr 21 03:09:22 THat one from the link? Apr 21 03:09:28 yes Apr 21 03:09:34 I was not going to get it. i know. Apr 21 03:09:59 same it looked a nice flexable cape Apr 21 03:10:23 It had some other items to get too, i.e. servo for a turret. Apr 21 03:10:40 Point and release the nerf! Apr 21 03:10:44 called manufacter but they would only build if quantity Apr 21 03:10:49 Oh. Apr 21 03:10:51 Dang. Apr 21 03:11:03 I am sure you could do it. Apr 21 03:11:23 I see how handy you are w/ source. YOu must know more than some people, i.e. me. Apr 21 03:12:16 motor via relay cape is easy. it's the servo that's problem Apr 21 03:12:54 Oh. Apr 21 03:12:59 What chip did they use? Apr 21 03:14:11 don't know t this point. since no longer made trashed docs. Apr 21 03:14:22 Oh. Apr 21 03:14:28 That makes sense. Apr 21 03:15:21 I'm NOT a code expert. Just relaying on past work Apr 21 03:15:26 Oh. Apr 21 03:15:30 Me neither. Apr 21 03:15:58 I just type up a bunch and try to make it works at times. In b/t that process, I try to learn from books and reading articles online. Apr 21 03:15:59 I got all this crap floating in my brain Apr 21 03:16:03 Ha. Apr 21 03:16:50 bash, c, fortran, cobol, basic and so on Apr 21 03:17:22 I know some of those are used to this day. Apr 21 03:18:01 I am not sure about fortran anymore. I read the other day that people still use it but for what, I did not figure out. Apr 21 03:18:23 in one form or another they all are Apr 21 03:18:33 See me, I am very forgetful. I can learn from 10 books and w/out reference, I know nothing. Apr 21 03:19:01 I read them up and down, over and over, and know nothing until I open one of them to find out what I had learned. Apr 21 03:19:11 I got some good e-books on BBB Apr 21 03:19:16 Me too! Apr 21 03:19:23 Which one, which one? Apr 21 03:20:07 13 of then. I got a deal for 18 bucks Apr 21 03:20:12 Nice. Apr 21 03:20:31 I bought mine in time. Over the years, I found them. Apr 21 03:20:55 I have some in hard copy and others in e-copy. Apr 21 03:21:05 one is BBB Cookbook Apr 21 03:21:15 Most of the ones from Packt are my soft copies. Apr 21 03:21:30 I never did want to purchase their titles in hard copy for some reason. Apr 21 03:21:31 me to Apr 21 03:21:39 OH. Apr 21 03:22:19 I read 'em over and learned basics in the BBIO and Adafruit_BBIO libraries. I also learned about bonescript. Apr 21 03:22:37 I have them zipped in a 200MB file Apr 21 03:23:27 I learned about how to interface sensors in different languages. All of them were good starting points on how to gather data, use it while learning more, and the books also helped me to figure out how to interface ideas to the BBB. Apr 21 03:23:30 Yes, Adafruit did some nice work Apr 21 03:23:50 I think so. I always wondered what happened to them in the BBB realm. Apr 21 03:24:05 I know they started mfg. their own boards after a bit. Apr 21 03:24:20 They had always had those neat modules. Apr 21 03:24:32 GPS and so on... Apr 21 03:24:42 I think Pi is much more pupolar then BBB Apr 21 03:24:47 It is. Apr 21 03:25:05 People are fanatical over the Pi. Apr 21 03:25:35 Although to me BBB is a real computer. not this raspian non-sense Apr 21 03:26:12 The Pi is more of a kit learning experience for some, I guess. I noticed their landing page was geared towards children. Apr 21 03:26:26 Folks are actually using Pi as a small desktop computer Apr 21 03:26:38 Yep. I see that around online. Apr 21 03:27:24 Now, I am not sure about their Cape support or daughter/add-on boards but BBB persons made some neat ones and recently, i.e. circa 2018. Apr 21 03:27:37 Look I have a real Dell laptop with the BBB being a attached computer Apr 21 03:28:10 Okay...okay. What are you doing w/ it? Apr 21 03:28:13 Pi calls capes hats Apr 21 03:28:18 Oh. Apr 21 03:28:28 I was unaware. Apr 21 03:28:44 Pi hats. Hmm. Apr 21 03:28:50 Yea, how's your 'hat' Apr 21 03:29:19 my laptop does everything Apr 21 03:29:33 Yep and quickly. Apr 21 03:29:56 It is fun to introduce new source/hardware to the BBB and all from a laptop. Apr 21 03:30:07 But... Apr 21 03:30:47 well by todays standards it's old. AMD 64bit *G ram & 1RB drive, 3 USB ports, Ethernet, Blue Tooth 17" screen Apr 21 03:30:48 Things changed for me. This means, either I have to learn to deal w/out Ada... and BBIO/other libraries or use mmap and/or fprintf. Apr 21 03:31:20 I have a laptop. I am not even sure what it has in it. I just know, dell ripped me off. Apr 21 03:31:26 They sold it to me as upgradeable. Apr 21 03:31:28 It is not. Apr 21 03:31:52 What model? Apr 21 03:31:59 There are no hard drives or ram for it. Apr 21 03:32:03 Let me go see. Apr 21 03:32:29 huh? Apr 21 03:33:28 Inspiron 5000 series. Apr 21 03:35:07 sorry. Inspiron 17 5000 series. Apr 21 03:36:58 The old article I received in the mail had a "killer" deal. I know why. It was not upgradeable like they stated. Apr 21 03:37:34 So, if something fails, I am out like $350.00 or however much it was at the time. Apr 21 03:38:28 Not even crucial.com had anything for it. Apr 21 03:40:01 that should be a nice 17" machine Apr 21 03:40:02 So, Dell sent a mailing to me b/c I signed up. I inquired about something. I wanted to find out why their site and everyone else's site stated _______________ in the field where I typed the type of ram/hard drive. Boo! Old beef. Apr 21 03:40:07 It is. Apr 21 03:40:09 It works. Apr 21 03:40:47 dvd, ethernet ? Apr 21 03:40:54 Ethernet. Apr 21 03:41:08 I think it may have a dvd. I am not sure. Apr 21 03:41:14 Yes, it does. Apr 21 03:41:35 Install Linux Mint LMDE4 Apr 21 03:41:35 I just remembered b/c I pushed the button once. Apr 21 03:42:20 How much RAM & Disk size? Apr 21 03:42:20 I have Ubuntu on it. I was going to put Debian on it also but I do not want three OSs on it. I am going to erase ubuntu and get my debian distro on it. Apr 21 03:42:33 1 tb and 4 gb Apr 21 03:42:49 I was looking to gather some more RAM for it. Apr 21 03:43:09 1 tb is more than enough. I always got by on 500 gb w/ tons of room. Apr 21 03:43:17 only 4gb ram. well change them out for 8gb and runoracle vm Apr 21 03:43:43 That is what I have been telling you. They do not mfg. the ram for that machine. Apr 21 03:43:59 12gb max Apr 21 03:44:05 Never did. It was a set up sell for a small time. Apr 21 03:44:26 I know what people say on their sites. It is not the truth. Apr 21 03:44:39 You cannot find the RAM anywhere. I promise you. Apr 21 03:45:20 go to newegg.com and put in model it will show you available ram. Apr 21 03:45:26 I know. I did. Apr 21 03:45:35 I went to crucial, newegg, and others. Apr 21 03:45:42 I spent many years on this idea. Apr 21 03:45:56 i expanded my ram? Apr 21 03:46:04 I went directly to Dell.com too. Apr 21 03:46:13 I have expanded ram before. Apr 21 03:46:21 It is not b/c ram is not expandable. Apr 21 03:46:33 It is b/c the ram on this inspiron is not expandable. Apr 21 03:46:48 what's the exact model, exact, 5000 is generic Apr 21 03:46:52 They do not make the ram on this machine. Apr 21 03:46:55 Please hold. Apr 21 03:46:59 I will go and check. Apr 21 03:48:41 P32E Apr 21 03:48:48 is it dell 15 inspiron 5000 Apr 21 03:49:11 No. 17. Dell Inspiron 17 5000 Series. Apr 21 03:49:37 I am warning you. It will drive you crazy. Apr 21 03:50:02 Your mind will actually explode since they made a computer w/out the capabilities of expansion. Apr 21 03:50:43 https://www.memorystock.com/memory/DellInspiron175000.html Apr 21 03:51:32 https://www.dell.com/support/manuals/us/en/04/inspiron-17-5767-laptop/inspiron-17-5767-servicemanual/before-working-inside-your-computer?guid=guid-5d3b1051-9384-409a-8d5b-9b53bd496de8&lang=en-us Apr 21 03:51:39 Check that link out. Apr 21 03:52:23 https://www.amazon.com/Upgrade-Inspiron-1600MHz-PC3L-12800-PARTS-QUICK/dp/B00PKLIAWO Apr 21 03:53:17 I do not know how you found that so quickly. Apr 21 03:53:21 That is very odd to me. Apr 21 03:53:52 They, some co, must have made that RAM since three years back. I stopped researching the idea. Apr 21 03:53:59 You site shows two SODIM modules Apr 21 03:54:09 And. Apr 21 03:54:10 ? Apr 21 03:54:18 I have two. Apr 21 03:56:05 Remove power & battery. remove DVD. remove cover on botton Apr 21 03:56:12 It is not true. Apr 21 03:56:15 I am sorry. Apr 21 03:56:24 whaaa Apr 21 03:56:26 All I have to do is remove a screw. Apr 21 03:56:38 I remove the screw and the bottom plate comes off. Apr 21 03:56:45 I can access the RAM that way. Apr 21 03:56:54 But...it is an odd size ram. Apr 21 03:57:00 always remove power & battery to avoid damage Apr 21 03:57:00 I cannot find it anywhere. Apr 21 03:57:06 Okay, okay. Apr 21 03:57:17 Sorry. You are right. Apr 21 03:57:35 just showed you 2 links. try amazon Apr 21 03:57:47 Okay. Thank you. Apr 21 03:59:03 Went to google and put in this search dell inspiron 17 5000 menory Apr 21 03:59:12 Okay, Okay, Okay. Apr 21 03:59:29 I have searched everything. I typed in the exact RAM module info. Apr 21 03:59:34 Notta. Apr 21 03:59:50 try my search Apr 21 03:59:57 Okay. Apr 21 04:00:07 I am going to try to make you understand one more time. Apr 21 04:01:18 oh it's tomorrow time for bed Apr 21 04:01:21 The RAM modules in this Dell Inspiron 17 5000 Series has a specific make and model. I searched the RAM module b/c when searching for the RAM during some years had nothing as feedback. Apr 21 04:01:23 Okay. Apr 21 04:01:41 I got it wrong. Thank you. Apr 21 04:02:06 order a set Apr 21 04:02:10 set Apr 21 04:02:40 Okay. Ha. Apr 21 04:02:48 I might. Apr 21 04:03:10 I will keep the site up, not Amazon, and decide soon. Apr 21 04:03:34 I need to check the exact model of my RAM again. Then, the decision is made. Apr 21 04:05:44 You have a 5759 right? Apr 21 04:06:06 Right. Apr 21 04:06:22 You don't like Amazon? Apr 21 04:06:30 I will check the RAM make/model and get back to you. Apr 21 04:06:38 THey were charging $80.00 +. Apr 21 04:07:10 cause you need a 'pair' of modules Apr 21 04:07:33 Oh. The other site was charging...oh. Apr 21 04:07:41 make sure pricing you are looking at is for 2 not 1 Apr 21 04:07:52 They do not sell 4GB * 2? Apr 21 04:08:15 B/c, I think 8GB is the max. Apr 21 04:08:26 you need a pair of 8GB sticks Apr 21 04:08:36 It cannot handle 16GB of RAM. Apr 21 04:09:04 It can only handle 8GB. See, I told you. Apr 21 04:09:11 Everyone is goofing up. Apr 21 04:09:30 Anyway, this is here nor there. The BBB must go on. Apr 21 04:09:53 you should not mis match memory modules Apr 21 04:09:59 I know. Apr 21 04:10:12 If I get two 8GB, that equals 16GB. Apr 21 04:10:21 It can only handle 8GB total. Apr 21 04:10:39 KenUnix: I am sorry. There is not a solution. Apr 21 04:11:11 well bbb goes on and I have to say good night... Apr 21 04:11:18 Again and I repeat, I will get the exact model/make of the RAM on this machine and get back to you. Apr 21 04:11:20 Okay. Apr 21 04:11:31 Good night for now. Apr 21 04:11:42 ummm tonight Apr 21 04:11:52 I can go right now if necessay. Apr 21 04:11:56 necessary? Apr 21 04:12:12 i'll wait not long Apr 21 04:12:28 Okay. Please hold. I will go pop this muffin off and get back quickly. Apr 21 04:14:56 Nope. It will take too long. Apr 21 04:14:59 Sorry. Apr 21 04:15:09 I think someone played a joke on me. Apr 21 04:15:18 I think someone switched out my computer. Apr 21 04:15:52 well we'll talk tonight Apr 21 04:16:02 Okay. Did it. Apr 21 04:16:10 I will talk to you another day. Apr 21 04:16:14 good night Apr 21 04:16:20 later. Apr 21 04:38:42 KenUnix: Apr 21 04:38:45 Dang it. Apr 21 05:13:29 Hullo everyone. Having brain tiredness today. Is it possible to drive both an LED and still supply a high line off each GPIO pin on the Beagle Bone Black. I am building some level shifter boards and I would like to put blinkin lights either on the input side or maybe on the +5 output side. The level translators are GTL2003PW's ... Apr 21 14:30:14 I think BeagleBone Black I/O drive is around 5mA, though I don't recall exactly. Just know the I/Os aren't meant to directly drive heavy loads. Apr 21 14:30:23 and at 3.3V. Apr 21 14:30:57 Plan for 3.3V @ 5mA on the I/Os and you should be OK. Apr 21 14:34:12 jkridner[m]: hi. do you have a part number for the BBB stacking cape connectors? I cannot find the "Major League" parts that are mentioned in the SRM Apr 21 14:34:42 jkridner[m]: something from Samtec, maybe? Connfly? Apr 21 14:34:55 Molex? *cough* Apr 21 14:35:35 Major League should still have them. I know Adafruit stocks some. Apr 21 14:35:50 * jkridner[m] looks to see what they stock. Apr 21 14:36:24 hmmm... not them: https://www.adafruit.com/product/2076 Apr 21 14:36:37 jkridner[m]: they already left, but yeah their VOL(max) and VOH(min) is specified at either 4 mA or 6 mA (depending on which pin) Apr 21 14:36:55 so I generally tell people to try to limit it to 4 mA Apr 21 14:37:36 k. didn't remember it went as low as 4. for some reason 5/10 was in my head. Apr 21 14:38:15 there's no clear spec of maximum current per pin though Apr 21 14:38:19 at least none that I've found Apr 21 14:40:18 I guess because it's mostly a thermal issue Apr 21 14:42:55 some V/I curves would be nice to have... I once tried to extract those from the ibis data but had a lot of trouble doing so, I couldn't find any free software capable of doing so, and when I tried it myself the data just didn't seem to make sense based on my best interpretation of the ibis spec Apr 21 14:44:19 jkridner[m]: yes, I found the adafruit kits, Mouser also stocks them. But I was hoping for something in the $1-$2 range, not $5 Apr 21 14:45:00 ah, for the stacking connectors, I don't think you'll find them very affordable unless you buy a bunch. Apr 21 14:45:19 I didn't find them at Adafruit just now... maybe I searched wrong? Apr 21 14:45:28 I recall them stocking them. Apr 21 14:45:55 well I have two kits in my mouser shopping cart right now ;) Apr 21 14:46:23 hmmm..... I think the Fan Cape uses the stacking connectors. I can research the part number on that. Apr 21 14:46:46 that would be fantastic. Apr 21 14:46:56 for most of our cape designs lately, we've gone surface mount, much to ds2 's chagrin. Apr 21 14:47:21 hr hr hr ;) Apr 21 14:48:06 yes, always cheaper if you can skip the manual assembly step for through-hole parts Apr 21 14:54:27 but doesn't that mean you have to change the cape outline to make room for the pins Apr 21 14:56:22 most of our throughhole assembly is with wave solder and custom fixture, but, for low-volume runs, doing a fixture isn't great. Solective sodler is an option at low-volume, but always nice when you can leave it out.... and those long leads can be a hassle. Apr 21 14:56:39 yes, SMT means the capes are slightly larger. :-( Apr 21 14:58:51 that can be problematic for existing cases... Apr 21 17:47:38 LeafDerekson Apr 21 17:48:28 Guest23504: if you intended to change your name, you can do so with something like: /nick LeafDerekson Apr 21 17:49:27 Thanks. this is new for me? just punch it in? Apr 21 17:49:35 sweet Apr 21 17:49:56 I have a question about flashing the disk image to the eMMC of the BBB Apr 21 17:52:11 I have the image on the SD card. It boots when I hold the boot button and plug it in. I dont understand how to edit the txt file using sudo nano /boot/uEnv.txt Apr 21 17:53:21 note that if you download a "Flasher" image (i.e. the "AM3358 Debian 10.3 2020-04-06 4GB eMMC IoT Flasher" on https://beagleboard.org/latest-images ) then you won't need to do that step. if you boot from such an image it will automatically reflash eMMC Apr 21 17:55:16 but yeah, turning a normal (aka standalone) image into a flasher is a simple matter of uncommenting (i.e. removing the "#" at the front of) a single line in /boot/uEnv.txt on the sd card, for example using nano (or any other text editor you prefer) Apr 21 17:57:23 but if you're very new to linux and not sure yet how to edit text files then just download the flasher image instead to sidestep the issue Apr 21 17:58:53 Ok. thank you Apr 21 17:59:38 Im working on a class project and did the classic "oh well this should just fix everthing... opps" Apr 21 18:00:26 well reflashing _is_ usually a great way to fix a system if it's ancient or messed up Apr 21 18:53:51 I have the SD card flashed and have it in the BBB. I held the S2 button while it powered on on the user leds are flashing back and forth sequentially. I think this means its working but how do I know its done? Apr 21 18:54:20 it will turn itself off Apr 21 18:54:32 you then remove the sd card and then just boot it again normally Apr 21 18:54:56 reflashing shouldn't take long Apr 21 18:55:23 afterwards you may want to erase the sd card so you don't accidently end up booting the bbb from it and causing it to intentionally reflash again :) Apr 21 18:55:48 Great. Im trying to figure out what I learned from this. I think the main lesson is check the date on Github page. Apr 21 18:55:58 what github page? Apr 21 18:56:59 Im using this with Bella. It was something from a bella forum question on a similar problem. I didnt get there from Beaglebone. Apr 21 18:57:28 bela you mean? Apr 21 18:58:03 don't they have their own specific firmware image? Apr 21 18:58:06 yeah. I took a wrong turn at the bela forum. Apr 21 18:59:38 yeah bela has its own custom image and their own instructions Apr 21 19:00:14 They do. I had messed up the bbb system though Apr 21 19:00:26 so flashing a standard image isn't really useful if you want to use bela Apr 21 19:00:44 I'm not sure I follow Apr 21 19:01:29 any time you flash a system to eMMC it will completely replace whatever was previously on eMMC Apr 21 19:02:06 so if you want to flash the bela image to eMMC then what you're doing currently is pointless Apr 21 19:02:27 I think bella says that I need the current BBB image on the board Apr 21 19:02:43 I dont falsh bela to the emmc it stays on the SD card Apr 21 19:02:44 if you intend to run from SD card I actually recommend you erase eMMC entirely Apr 21 19:02:58 hm Apr 21 19:03:24 I did entirely erase the eMMC and nothing would boot Apr 21 19:03:29 (to ensure it will use the bootloader on SD card and not one on eMMC, which takes priority if present, unless you power on while holding down the S2 button) Apr 21 19:03:35 huh Apr 21 19:03:43 their image is missing a bootloader? Apr 21 19:04:03 that sounds very weird if true Apr 21 19:04:09 Im not sure. Ill get back on their forum right now and ask some questions Apr 21 19:04:20 lemme download their image and check Apr 21 19:05:52 no actually their instructions including making eMMC unbootable as option (which is most easily accomplished by erasing it) Apr 21 19:06:49 so, let me clarify Apr 21 19:07:13 if there's a bootloader present on eMMC then it will normally always be used, regardless of whether an SD card is present or not Apr 21 19:07:40 typically the bootloader will prefer booting linux from SD card (if present) and otherwise it will boot linux from eMMC Apr 21 19:08:54 however this can cause compatibility issues: the bootloader on eMMC may be older or newer than the system on SD card, or it may just be configured in a way that the system on SD card doesn't expect, potentially resulting in anything from weird subtle issues to complete failure to boot Apr 21 19:09:08 the workarounds are: Apr 21 19:09:33 1. flash the system to eMMC instead of booting from sd card Apr 21 19:10:11 2. wipe eMMC (or at least the bootloader on eMMC), in which case the bootloader on SD card will be used instead Apr 21 19:12:12 3. override the boot order to make the bootloader on SD card be used in favor of the one on eMMC. This is what you're doing when you power on while holding down the S2 button. It can also be overridden by pulling certain P8 pins up/down, which is what they're doing (in an unnecessarily complicated way) in "Option 1" of https://github.com/BelaPlatform/Bela/wiki/Manage-your-SD-card#booting-problems Apr 21 19:14:06 option 2 in that section is wiping the bootloader from eMMC, although I'd just suggest booting from SD card (by using the S2 button as override) and then wiping eMMC entirely using "sudo blkdiscard /dev/mmcblk1" ... this is assuming the contents on eMMC doesn't matter Apr 21 19:15:45 LeafDerekson: I hope this makes sense Apr 21 19:17:33 Sort of. I will figure it out because I have to. Option 2 seems more understandable to me. Do you think 2 is simplest? Apr 21 19:18:45 so, 3 is how you can boot an SD card image regardless of what's on eMMC, so it's useful as a temporary override to get the bela image to boot initially Apr 21 19:20:35 once you've done that, options 1 and 2 are both equally easy, they're both a single command (either "sudo blkdiscard /dev/mmcblk1" to wipe eMMC or use their /opt/Bela/bela_flash_emmc.sh to flash the bela image to eMMC) Apr 21 19:21:11 it just depends on whether you prefer to run from SD card or from eMMC Apr 21 19:21:42 It doenst matter to me but these belong to a school and I should put it back the way I found it. Apr 21 19:22:47 that requires knowing what was on it in the first place Apr 21 19:24:01 I have that. I did have enough forsite to make a copy of what was on it. The problem came up when my computer coudnt find the device Apr 21 19:24:04 it sounds like an odd requirement though since using a beaglebone almost always requires installing stuff and customizing stuff, so generally I'd assume that you'd simple wipe/reflash them between users Apr 21 19:24:15 *simply Apr 21 19:24:35 either that or leave it wiped and run from sd card Apr 21 19:24:54 how did you make a copy of what was on it? Apr 21 19:25:31 I jsut dragged it out and put the contents in a new file thinking I could just put it back in if things went wrong Apr 21 19:26:10 I have no idea what you mean by that. dragged what out of what? Apr 21 19:27:38 regardless of what you meant by that, it doesn't sound like it could possibly describe a way to make a backup of the eMMC contents Apr 21 19:28:20 ok, Then I didnt make a backup? Apr 21 19:30:15 like I said I have no idea what it even is you're describing, however the process of making a backup of eMMC doesn't involve "dragging" anything, it involves logging in on the beaglebone to issue a command that backs up the contents of eMMC to an SD card Apr 21 19:30:18 I took my sd card with bela out. pluged the BBB into my computer saw a drive that said Beagle. Copied that stuff into a folder and then messed everting up. I pluged the BBB back into my computer and found no drive named Beaglebone and the BBB device only had the power light on. Apr 21 19:31:55 that drive is basically irrelevant, it's just a tiny disk image containing some documentation and drivers for old OSes that need it (windows 7 and older) Apr 21 19:32:18 what did you "mess up" ? Apr 21 19:33:03 I assumed I messed it up because the unit would not boot. only the power light would come on. Apr 21 19:33:31 I mean that does sound compatible with the word "messed up", but you haven't described what you did to get at that point Apr 21 19:34:29 but anyway, did you borrow that beaglebone just standalone, or did it come with bela cape and sd card? Apr 21 19:35:00 since in the latter case the eMMC contents is probably irrelevant and best left erased Apr 21 19:35:03 it came with he cape and sd card. Apr 21 19:35:53 like I explained earlier, if you want to run from sd card it's better to leave the eMMC wiped to ensure the bootloader is loaded from sd card, thus avoiding any risk of incompatibility between bootloader and the system on SD card Apr 21 19:37:07 that way it will boot without any problems from any bootable sd card Apr 21 19:39:12 otherwise, if a bootloader is present on eMMC (which is a requirement to have a bootable system on eMMC), there's a risk of (subtle or unsubtle) problems when booting from an SD card containing a system that is significantly older/newer/different from the one on eMMC Apr 21 19:39:33 anyway, I need to do shopping, bbl Apr 21 19:41:13 I understand. I need to make lunch thanks for your time. I feel less freaked out. this was all supposed to be easy. My prof wants me to figure this stuff out because she doesnt know how it works. Sometimes I feel like im trying to shove a PBJ into a VCR Apr 21 20:36:52 lol Apr 21 21:45:20 Is GenTooMan still breathing? I am asking b/c I shelled out the funds for the TTL to USB (5v). Is this going to take the place of the Half Duplex UART? Apr 21 21:45:52 GenTooMan! Apr 21 21:46:45 Anyway, I will stay patient. I am sure people are busy. Apr 21 22:49:59 bbl! Apr 22 01:04:20 set_ Got your ears on ? Apr 22 01:06:29 set_ OhOh I got that info for you 8) 8) Apr 22 01:07:58 For the Servos? Apr 22 01:10:38 ddr4! Apr 22 01:11:42 Depending on what you have now. If you have a 4 gb stick now order a match to it. If not you can order 2 4gb sticks recommend. Or you can order a single 8gb stick. Apr 22 01:12:42 yep Apr 22 01:12:44 Does this help? Apr 22 01:12:57 Sure. Apr 22 01:12:59 Thank you. Apr 22 01:13:39 I went to the manufacturer and asked Apr 22 01:13:57 nice Apr 22 01:14:26 dell? Apr 22 01:14:38 Believe it or not my bwbasic project now shouws up in google search Apr 22 01:14:58 Hey. Apr 22 01:15:01 Dell ? Apr 22 01:15:07 What does bw in the bwbasic mean? Apr 22 01:15:39 BayWater. I didn't do it. Apr 22 01:15:46 Okay. Apr 22 01:15:55 hold Apr 22 01:16:11 BayWater...hmm. Okay.

Apr 22 01:17:23 DDR4. Apr 22 01:17:50 You have DDR4? Apr 22 01:17:50 KenUnix: I decided, after you took off, to take the old 'puter apart. Apr 22 01:17:53 Yes. Apr 22 01:18:50 Anyway...not to be a stickler but BBB and not dell over here for now. I am trying to catch GenTooMan's attentive moods. Apr 22 01:19:22 I am making a thing-a-ma-bob for a servo or many servos. Apr 22 01:19:27 I cannot tell just yet. Apr 22 01:19:38 Methinks need not follow every sentence... IRC != SMS Apr 22 01:19:50 Okay. Apr 22 01:20:34 What else? Apr 22 01:20:53 I'm by no means anyone important around here. Just encouraging good IRC etiquette. Apr 22 01:21:18 I got you. This room is for beagleboard.org and related inquiries. I understand completely. Apr 22 01:21:57 KenUnix: See what you did! Apr 22 01:22:40 Aw Apr 22 01:22:54 OK Last Dell SNPTD3KXC/8G A8547953 8GB (1 x 8GB) 260-Pin DDR4 2133MHz Sodimm Apr 22 01:23:24 Enough Dell for tonight Apr 22 01:26:57 Okay. I am sorry too. Apr 22 01:27:09 Sorry for blaming you. I had a hand in it too. Apr 22 01:28:43 Well I can't tell you what I found on MS Apr 22 01:29:18 Do not worry about it. I will deal w/ it. I think I am affecting people in a not-so-nice way. Maybe we can break for a bit. Apr 22 01:29:48 I'm sucking down a cup of Joe Apr 22 01:30:28 3 creamers and 5 Equal Apr 22 01:30:39 Bored...are we? Apr 22 01:30:49 yep Apr 22 01:31:04 Okay. I have a circuit I am working on. Apr 22 01:31:11 Would you like to see it? Apr 22 01:31:28 Ultimately, it will go to the BBB for comm. and feedback. Apr 22 01:31:37 Sure X) X) Apr 22 01:31:43 Please hold. Apr 22 01:32:05 UART, or something else? Apr 22 01:32:17 I love this technical stufff Apr 22 01:32:56 Yes. Apr 22 01:33:09 Half Duplex UART w/ the "fixings." Apr 22 01:33:25 I need a cap per input on these chips. Apr 22 01:33:37 preferably near the power source. Apr 22 01:33:54 Get a blank cape Apr 22 01:34:42 I think he was referring to capacitors, though I may be wrong. Apr 22 01:35:17 Oh a .1 MFD cp.? Apr 22 01:35:22 Given the context, cap = "capacitor" makes more sense. Apr 22 01:36:11 caps. yes. Not the Capes. Apr 22 01:36:14 MFD = Micro Farrad Whats the D I gorget? Apr 22 01:37:02 Hard to get just a couple Apr 22 01:37:49 No Radio Shack anymore Apr 22 01:37:58 0.1 uF bypass caps need to be placed at each Vcc. Sorry. Apr 22 01:38:13 For the HC04. Apr 22 01:38:16 0.1u's are about as common as grains of sand Apr 22 01:38:37 Yes, common but important Apr 22 01:38:41 Right. From what i heard, they are just common parts. Apr 22 01:39:10 How many volts? Apr 22 01:39:56 Are the .1's polarized? Apr 22 01:40:03 And no floating of pins. I just keep reading more. Either I have to put all input pins high or low. Apr 22 01:40:28 Yes, pull up or pull down Apr 22 01:41:04 KenUnix: IIRC, the "D" is the "D" in Farad. That terminology is antiquated, for good reason. Apr 22 01:41:04 """...The units of capacitance are labeled in microfarads (µF). Older capacitors may be labeled with the obsolete terms "mfd", which means microfarad and "MFD" means millifarad.""" Apr 22 01:41:43 Augh... got too much of the quote. Should just be the last sentence, (about older capacitors using this unit terminology). Apr 22 01:41:53 Well i'm obsolete Apr 22 01:42:17 * IanWizard feels more obsolete than ever lately. Apr 22 01:42:38 Look back in electric shop in high school 1964 ;( Apr 22 01:43:33 Not to make you feel old, but... you've made me feel young now. I needed that :) TY. Apr 22 01:43:36 -----||--- Apr 22 01:44:00 or ---)|---- Apr 22 01:44:36 Oh the Comptroller has left. Let's all binge Apr 22 01:44:49 -----)|-- (A tiny sword for a mouse.) Apr 22 01:45:28 "condensers"? Apr 22 01:45:48 Back ten they had some vacuum tube projects. Can you make your hair stand up. Apr 22 01:46:35 I have not heard 'condenser' in a long time Apr 22 01:46:40 I think the alcohol's kicking in. I'm starting to feel a bit mellower. Apr 22 01:46:41 set_: You were going to share a circuit you were working on? Apr 22 01:47:43 brb :b Apr 22 01:48:10 set_ where's that diagram? Apr 22 01:49:08 Comptroller is back hide he money =D Apr 22 02:04:23 Sorry. Apr 22 02:04:35 I got lost looking at imgur while I was uploading. Apr 22 02:04:48 I cannot handle anything right now.

It needs work. I will reconvene later w/ this circuit. Apr 22 02:09:54 Don't download 'Advanced port scanner' or 'Advanced IP scanner' it puts the machine at 100% hung on interrupt handling Apr 22 02:11:35 For transceivers, it totally kills all output enable pins if they one is floating. Apr 22 02:12:15 they one = only one Apr 22 02:17:47 does anyone have a link to a good primer on least-significant byte or most significant byte or endian Apr 22 02:17:55 i do not understand any of that stuff Apr 22 02:17:58 is that binary logic Apr 22 02:18:27 like this sentence "These commands will result in a one-byte serial response from the jrk containingjust the most-significant byte of the variable." Apr 22 02:18:30 what does that mean Apr 22 02:22:04 https://youtu.be/ayul1fmZd0Y is something. Apr 22 02:22:19 That young gent knows his MSB and LSB. Apr 22 02:22:46 MattB0ne: ^ Apr 22 02:25:28 Generally 1 byte is 8 bits Apr 22 02:25:41 got that Apr 22 02:26:06 you do know the origin for the bit Kenunix don't you? Apr 22 02:26:32 Little Endian relates to memory addressing and memory words Apr 22 02:26:54 is there a umbrella term that will cover all of this Apr 22 02:27:31 Did you try a google search? Apr 22 02:27:45 i did but i was looking for a consolidate resource Apr 22 02:27:56 like this is such and such of assembly language Apr 22 02:27:58 cheatsheet? Apr 22 02:27:58 go study that Apr 22 02:28:12 i want one level of abstraction Apr 22 02:28:40 See this https://chortle.ccsu.edu/AssemblyTutorial/Chapter-15/ass15_3.html Apr 22 02:28:54 GenTooMan: I am working on the circuit now. I will update soon. Apr 22 02:30:30 KenUnix: thanks for the link Apr 22 02:30:46 I wasn't expecting to have to know assembly Apr 22 02:30:56 This is nice also https://en.wikipedia.org/wiki/Endianness Apr 22 02:31:31 well old boys knew it because they had to other reasons are for when you need to tweak as much out of something as possible. Apr 22 02:32:41 Yea, like Unix on a Motorola M68010 CPU Apr 22 02:33:24 why didnt pascal take off Apr 22 02:33:38 honestly it was too limited Apr 22 02:34:00 i remember learning basic and pascal as a kid Apr 22 02:34:12 I had a turtle i would draw boxes and crap on the screen Apr 22 02:34:13 lol Apr 22 02:35:09 How about Forth? push op uug Apr 22 02:35:19 How about Forth? push pop uug Apr 22 02:35:23 I remember when I started before the "big bang in life," we would draw rectangles in some language. I cannot even remember. Apr 22 02:36:09 Turbo Pascal, Borland Turbo 'c' Apr 22 02:36:55 reverse polish notation! Apr 22 02:36:56 I never tried Ada Apr 22 02:37:06 ada is abusive Apr 22 02:38:03 this is an awsome site KenUnix Apr 22 02:38:08 breaking it down Apr 22 02:38:21 starting from chapter 1 Apr 22 02:38:31 Working at Bell I had to learn RPG Report Generator for AR&T Unix Apr 22 02:38:58 how many language would you say you know Apr 22 02:39:12 if you want to learn something cool Prolog... still like it today. I wrote an assembler in 201 lines and a C compiler that used the assembler in 334 lines Apr 22 02:39:38 however it is and was REALLY slow Apr 22 02:40:53 Been there : floating-point processor on the PDP-11/45 and PDP-11/70 Apr 22 02:42:03 Can you say core dump Apr 22 02:42:40 Then we had to use adb to analyze core file Apr 22 02:43:05 adb = Advaned DeBugger Apr 22 02:43:39 so the assembler converts assemlby code to binary Apr 22 02:43:40 right ? Apr 22 02:44:12 Assembler converts code to machine instructions Apr 22 02:44:38 Yes binary, Hex, Octal whtever Apr 22 02:46:57 GenToo 'c' compiler in 334 lines?
