**** BEGIN LOGGING AT Sun Jun 02 02:59:58 2019 Jun 02 03:07:00 Dudes and Dudets, have you seen: https://github.com/torvalds/linux/blob/master/Documentation/admin-guide/devices.txt? Jun 02 03:07:08 this is absurd. Jun 02 03:07:42 There are unlimited ideas circulating. What are people doing? Jun 02 03:07:54 Please someone make a book. Jun 02 03:08:49 I tried and was laughed at during the process. Jun 02 03:08:56 People will not take time out. Jun 02 03:52:34 One thing that gets me, why are we allowed to use an older system if it has been updated? Is there reasons for using /sys still outsides of character devices? Jun 02 03:52:51 b/c of history? Jun 02 03:57:59 Will you please add the module /dev/djs0 to the kernel, rcn-ee? Jun 02 04:12:24 or...do I need to use the CC w/ uboot? Jun 02 06:26:15 > https://www.reddit.com/r/amateurradio/comments/bvp49z/my_mom_is_making_a_cake_for_my_little_sisters/ **** BEGIN LOGGING AT Sun Jun 02 08:28:05 2019 Jun 02 08:41:14 hello Jun 02 10:12:55 is there a way for the beagle to determine on boot by detecting what it's plugged into (host or device) on its usb port which type of device it should become. Jun 02 11:44:33 JGalt: the beaglebone doesn't have an OTG port Jun 02 11:49:03 it has an USB A port which is host-only and a mini USB B (BBB) or micro USB B (BBBW) port which is device-only Jun 02 11:49:51 switching role requires a micro USB AB port and additional vbus power switching electronics (with potentially tricky interactions with the PMIC) Jun 02 12:32:49 May I ask a question here? Jun 02 12:39:24 I am doing product development using Beagle Board x15. Jun 02 12:39:30 Should I Get an HDMI License? Jun 02 12:47:54 hm, that's an interesting question Jun 02 12:48:12 I have no idea Jun 02 12:51:48 Thank zmatt! Jun 02 12:52:33 I have no idea too...ummm Jun 02 13:09:36 I purchased new BeagleBoard-XM. There is no power cable. Is it suppose to come with power cable? Jun 02 13:11:54 wow I didn't know the xm was still being sold Jun 02 13:14:21 Cable is not included. Jun 02 13:14:23 you mean a power adapter? probably not no, since those would vary per country Jun 02 13:14:45 and neither the beagleboard-x15 nor any of the beaglebones include one Jun 02 13:18:05 see chapter 5 of the beagleboard-xm system reference manual Jun 02 13:19:44 5 and 6 Jun 02 13:27:50 Yes, I meant power adapter Jun 02 13:28:15 Thank you! I'll order the power adapter. Jun 02 15:27:31 https://pix.watch/gbaj0N/LO0y5O.jpeg Jun 02 15:27:40 perfect solution for upcoming lithium fire disaster Jun 02 16:58:23 nawk How so? I mean you are expecting a lithium fire or preventing one? Jun 02 17:00:59 how do you know its a Li battery? Jun 02 17:02:34 aah is this supposed to be an open "power bank"? Jun 02 17:03:20 H18650 says it probably. Jun 02 17:06:44 I'm flashing a bbb with a BBB-blank-debian-9.5-iot-armhf-2018-10-07-4gb.img ....it's been blinking for about an hour now Jun 02 17:07:08 Anyone had experience with it "failing" that way? Jun 02 17:08:22 I haven't then again I haven't had time to work on BBB for 5 years. Now I do but don't. Jun 02 17:08:45 Short not me did you check the manual? Jun 02 17:10:17 Not yet no. I will now, thansk for pointing it out :) Jun 02 17:14:34 outrageous: blinking in what way? Jun 02 17:15:01 zmatt: All four blinking as it is supposed to do while flashing the image to the eMMC Jun 02 17:15:13 blinking simultaneously? Jun 02 17:15:23 zmatt: Indeed. Jun 02 17:15:34 that's not "as it is supposed to", that just means it failed Jun 02 17:16:09 for example because the target eMMC has insufficient space Jun 02 17:16:33 (BBB prior to revision C had only 2GB of eMMC) Jun 02 17:16:38 zmatt: I see. I must have misread or misinterpreted the info I found then. Jun 02 17:19:08 flashing uses a back-and-forth pattern: 0 1 2 3 2 1 0 1 2 3 2 1 0 (aka "cylon" or "knight rider") Jun 02 17:20:26 zmatt: Thank you for that. It has the 4GB eMMC ...so I must have messed something up. Jun 02 17:20:58 problematic sd card maybe? Jun 02 17:22:04 be sure to write the sd card using a tool that verifies the card after writing it, e.g. Etcher Jun 02 17:22:39 zmatt: Could be, yes. I was just doing it the DD way on the BBB Jun 02 17:24:10 zmatt: Has worked for me in the past ....but it's been some time since I last did this. Jun 02 17:25:16 an sd card that was okay in the past isn't necessarily still ok. cards fail due to usage (specifically writes) Jun 02 17:29:29 sad truth is zmatt is correct wear on SD cards because they oft use MMC nand flash tends to be much faster. because instead of 100000 cycles they are reduced to 3000 cycles. Works fine for photos. Jun 02 17:29:50 modern sd cards are TLC, not MLC, afaik Jun 02 17:30:14 (i.e. even worse) Jun 02 17:31:08 zmatt: I have only used this once before, but I have plenty of them so I will try swapping it out and going through the procedure I used. Thank you :) Jun 02 17:32:10 outrageous zmatt suggestion of checking before starting the flash is not an unwarranted suggestion. Jun 02 17:32:24 GenTooMan: in fact apparently there are already products with QLC flash (16 levels per bit) Jun 02 17:33:12 zmatt here I thought MLC was any multilevel flash. Not specific types. That is very hard to ... ave work a long time. Nand flash has turned to junk technology woo hoo. Jun 02 17:33:39 MLC has become to mean 4-level specifically Jun 02 17:34:15 I mean, SLC is still around, and SLC/pSLC sd cards aren't even *that* expensive Jun 02 17:35:59 I guess that is because the first ones were 2 bits, and DLC likely not great for marketing people. SLC has better endurance lower density obviously. Jun 02 17:36:21 SLC is also faster, especially for writes Jun 02 17:52:59 zmatt point well taken it's difficult to program a multilevel cell due to it's analog nature so yes that makes sense. Jun 02 17:53:38 has anyone mess with the x15 (or BBAI) and TIDL? Wonder how does it compare to something like the Jetson Jun 02 17:53:52 yep, instead of programming the bit fully it needs to be carefully programmed to a specific level Jun 02 18:26:08 BBAI looks like something I can use. I hadn't heard of it before now. Jun 02 18:29:23 Probably doesn't have the same processing power as the Jetson but wins in IO. Jun 02 20:04:39 yes Humpelstilzchen , I'm trying to make an additional li-ion charger for my ecigarette consumption Jun 02 20:04:48 only one charger isn't enough for both me and my girlfriend Jun 02 21:07:19 charger for gf Jun 02 21:12:09 nawk using a beagle board? Jun 02 21:12:36 it's a m not a n Jun 02 21:12:47 no GenTooMan a charger doesn't need to be smart Jun 02 21:13:24 charger ic, comparator & led driver IC Jun 02 21:13:33 even no microcontroller Jun 02 21:15:47 nawk ahh non topical. for a charger there are a number of USB power source ICs you can use. I understand that charging time for people who use eCigarettes is a problem? Jun 02 21:52:40 yes GenTooMan Jun 02 21:53:01 they're like 3000mAh batteries Jun 02 21:53:17 and are made to support high current discharge, so they won't suffer being charged faster Jun 02 21:57:48 mawk that is a pretty size able battery. are they mostly LiPo or 18650 size? Jun 02 21:58:20 only 18650 Jun 02 21:58:29 I've not seen ecigs with lipo for now Jun 02 21:58:38 cylindrical battery is perfect for a cigarette looking item Jun 02 22:11:36 mawk I suppose so. It's a simple enough device. How long does a battery last on continuous use? 5-6 hours about? Jun 02 22:12:11 yes something like this, a bit less Jun 02 22:13:13 it's like 4 seconds per vapor puff, at 30W Jun 02 22:13:52 18650 seems more like a cigar than a cigarette Jun 02 22:18:43 lol Jun 02 22:38:12 mawk Yes not something you would want to smoke though considering the contents of a lithium ion battery are loaded with toxic fluorocarbons Jun 03 00:26:38 Now...can someone please put the djs0 module in the /dev dir? Jun 03 00:39:39 Do I have to put the djs0 module in the /dev dir. or should I compile an image for this idea? Jun 03 00:43:19 Oh! Do I need to write a kernel module and then compile the kernel module? Jun 03 00:55:00 djs0? what's that? Jun 03 00:55:09 digital joy stick Jun 03 00:55:26 what kind of HW provides that? Jun 03 00:56:08 Hardware? Do you mean like what exact piece of joystick or controller? Jun 03 00:56:41 yes or cape or etc Jun 03 00:56:52 Either, I do not know. I just thought that this was for making joysticks (digital) work w/ the BBB or related board. Jun 03 00:57:29 wonder how is that different then exposing it as an input event device Jun 03 00:57:56 I will inevitably need to know more. I am going to try to compile it w/ kbuild as a module first. Jun 03 00:58:17 if you don't have the HW, why are you building the SW? Jun 03 00:58:24 seems backwards Jun 03 00:58:51 Oh. Yea. Sometimes I do try to get hardware first. This time, I am going to try the software first. Jun 03 01:00:05 I mean...I can try a normal joystick, I guess. I will look up more on the admin side of things for djs0 modules. Jun 03 01:08:15 set_ you could try an abnormal joystick? Jun 03 01:11:42 set_: you're not making sense, as usual. are you talking about an usb joystick of some sort? assuming it's supported by linux the device should simply show up when you plug it in Jun 03 01:13:11 Oh. Jun 03 01:13:55 I figured I would learn how to produce kbuild and makefile modules w/ cross compilation. Jun 03 01:14:05 I am learning now. Jun 03 01:14:27 I have no idea what you mean by that Jun 03 01:14:27 I figured since this djs0 is not available on the BBB kernel now, I could try it out. Jun 03 01:14:47 that makes no sense Jun 03 01:14:47 Okay. Jun 03 01:14:48 Okay. **** ENDING LOGGING AT Mon Jun 03 02:59:57 2019
