**** BEGIN LOGGING AT Tue Jun 11 03:00:01 2019 Jun 11 03:17:07 yeah, sounds like that would make it much simpler Jun 11 03:24:07 i probably won't bother making an executable script for this, just a human "script", since hopefully rcn can be convinced to make it unnecessary Jun 11 03:40:14 damn fdisk's use of geometry is annoying Jun 11 03:40:25 ? Jun 11 03:42:08 fdisk -d and -r can be used to dump and load MBR. but the dump format includes the starting and stopping cylinder/head/sector positions Jun 11 03:42:32 oh fdisk on linux long stopped with that nonsense Jun 11 04:07:13 fortunately if i just use it interactively, "CHS mode" is optional Jun 11 04:07:35 but… a little help? Jun 11 04:07:35 fdisk: 1> edit 1 Jun 11 04:07:35 Starting Ending Jun 11 04:07:35 #: id cyl hd sec - cyl hd sec [ start - size] Jun 11 04:07:35 ------------------------------------------------------------------------ Jun 11 04:07:35 *1: 83 0 130 3 - 108 91 47 [ 8192 - 1732608] Linux files* Jun 11 04:07:36 Partition id ('0' to disable) [0 - FF]: [83] (? for help) Jun 11 04:07:36 Do you wish to edit in CHS mode?

Jun 11 04:09:16 if you have ext2-utils on mac, can't you also just compile sfdisk from util-linux on mac? ;P Jun 11 04:09:24 I don't know anything about mac's fdisk Jun 11 04:09:42 i looked for sfdisk in homebrew, without success Jun 11 04:09:58 well i doubt the answer to that question is mac-specific in any way Jun 11 04:10:20 the "edit" command doesn't exist in linux fdisk Jun 11 04:10:27 orly Jun 11 04:10:35 in fact the whole appearance and command syntax appears to be different Jun 11 04:10:47 !@#$ Jun 11 04:10:56 basically all the two utilities share is the name and general purpose Jun 11 04:11:47 just realized i can input what i think is right, then preview resulting table before writing Jun 11 04:14:45 looks good except it seems to have obliterated the CHS: Jun 11 04:14:46 Starting Ending Jun 11 04:14:46 #: id cyl hd sec - cyl hd sec [ start - size] Jun 11 04:14:46 ------------------------------------------------------------------------ Jun 11 04:14:46 *1: 83 1023 254 63 - 1023 254 63 [ 8192 - 819296] Linux files* Jun 11 04:15:30 will linux just ignore those anyway? Jun 11 04:16:45 I'd presume so Jun 11 04:17:28 ok, seems a risk worth taking Jun 11 07:44:21 Hey guys, Jun 11 07:45:36 I was looking for a Demo for the temperature and pressure. It seems that this page was malicious modified http://beagleboard.org/Support/BoneScript/demo_bmp085/ Jun 11 07:51:46 fg: certainly does Jun 11 07:51:54 zmatt? Jun 11 07:54:07 don't look at me, I don't work for beagleboard.org or have anything to do with the site Jun 11 07:54:11 poke jkridner[m] Jun 11 08:03:12 The page says: "Last updated by default on Wed Nov 28 2018 15:06:06 GMT-0000 (UTC)" Jun 11 09:16:48 JOIN Jun 11 09:17:43 gowdham: congrats, you're in! Jun 11 09:18:40 Hi how can i build Debian stretch OS for Beagleboard X15? Jun 11 09:19:02 kindly share any guide? Jun 11 09:19:17 you sure you want to build it instead of using one of the pre-made images? Jun 11 09:21:36 there are several. do you want just a minimal installation (console), a desktop environment (LXQT), or desktop env + beaglescript IDE? Jun 11 09:22:14 the latter two are linked here: http://beagleboard.org/latest-images Jun 11 09:23:36 eh seems i screwed up those options. the latter two should be beagle stuff with or without a desktop env Jun 11 09:24:20 i've never used anything but the console images, so idk exactly what the others include Jun 11 14:58:21 m Jun 11 15:34:22 Hello i've downloqde latest 9.5 i;mqge to my bbone and need to install gst-inspect-1.0 avdec_h264 gstreamer plugin... Any ideas? Jun 11 15:35:48 Trying again... Jun 11 15:37:58 I've installed latest 9.5 image to my bbone. I'm trying to display h264 stream usimng gstreamer. iǘ installed gstreamer and it's plugins, however avdec_h264 is missing... Any ideas? Jun 11 19:41:19 did anyone read the 5v measured voltage from the beaglebone pmic? Jun 11 19:41:39 sure Jun 11 19:43:10 it's basically equal to the 5v input (whenever the beaglebone is powered on) Jun 11 19:44:41 I'm thinking about abusing a beagle to monitor the 5v I have generated here Jun 11 19:45:56 oh maybe I misunderstood your question... I have measured the 5v that comes from the pmic (sys_5v). if the "from" was referring to "read" rather than "voltage" then sorry, the pmic has no voltage readouts whatsoever Jun 11 19:46:34 it probably doesn't even have any adc, just some comparators Jun 11 19:47:43 too bad. I was hoping to avoid the need to solder input voltge to an adc Jun 11 19:49:03 if you intend to use the beaglebone's on-board adc, be very careful not to exceed its voltage rating Jun 11 19:49:59 no worry, I have heard the word voltage divider before :) Jun 11 19:50:14 that, but also when using it to monitor some external supply, you'd need to ensure the beaglebone is powered up before the external supply is Jun 11 19:52:04 I'll probably use an avr for this job..if I have to solder I solder everything Jun 11 19:52:15 fair Jun 12 01:54:53 Should I be able to supply a 5v module w/ 5v from the BBB if I am plugged in via sys_5v, i.e. for a LCD screen? Jun 12 01:55:10 I am asking b/c I think my connections are correct w/ the software but the dang LCD is not powering on. Jun 12 01:55:57 Or... Jun 12 01:56:02 Should I use vdd_5v? Jun 12 01:56:11 sys_5v typically Jun 12 01:56:31 @zmatt in da' house. Okay. Thank you. I am one step closer. Jun 12 01:57:46 @zmatt: Typically, would the LCD show light on the dash when powered or would software first need to be implemented? Jun 12 01:58:11 typically it needs to be enabled by software Jun 12 01:58:17 Okay. Jun 12 01:58:46 Good and not so good. I am dealing w/ this fellow from Udemy and the Eclipse IDE for fun. Jun 12 01:59:13 The software is on the BBB for handling the LCD. Jun 12 01:59:17 But! Jun 12 01:59:51 No lights. No LCD. No power. I think this board is different than the one he was describing even though he linked to this page online. Jun 12 01:59:52 ... Jun 12 02:00:10 Probably...just another oops. Jun 12 02:01:02 I see this arduino shield has 5v on another pin unlike what was described. I will try to hook up there instead this time. Jun 12 02:01:27 ehm Jun 12 02:02:04 I know. No time for it. It is okay. Jun 12 02:02:16 ? Jun 12 02:02:36 @zmatt: Do you have time for this device and my lack thereof? Jun 12 02:03:07 if you're ever going to tell us which lcd device you're talking about Jun 12 02:03:12 Oh! Jun 12 02:03:19 LCD Keypad Shield. Jun 12 02:03:34 That is what it says on it. Jun 12 02:05:15 There are too many. Let me get the correct site. Jun 12 02:06:20 and what made you believe it is compatible with the bbb ? Jun 12 02:06:25 https://www.ebay.com/itm/16x2-LCD-Keypad-Shield-LCD1602-1602-Module-Blue-Backlight-Display-For-Arduino/202676046439?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 Jun 12 02:06:27 ... Jun 12 02:06:45 The sys_5v and this fellow online. Jun 12 02:07:08 It comes w/ a pot. Jun 12 02:09:08 based on one minute of googling, that shield cannot be used with 3.3v I/O Jun 12 02:09:15 hence is not compatible with the BBB Jun 12 02:09:29 Oh. Jun 12 02:09:31 Dang it. Jun 12 02:09:38 I wonder what this fellow was thinking. Jun 12 02:10:00 Oh well. Jun 12 02:16:33 What if I use a 10k pot to attach vcc to T1 (pot), T2 (pot) to GND, and the wiper (pot) to a "contrast adjustment" pin on the LCD? Jun 12 02:17:19 then nothing because it's not compatible with 3.3v signals, which is what the BBB uses Jun 12 02:17:27 Okay. Fine. Jun 12 02:29:36 So, using a 16 pin or 32 pin 3.3v to 5v level shifter can work? Jun 12 02:30:18 probably don't need that many pins, but sure Jun 12 02:30:30 Okay. So, just for the GPIO pins? Jun 12 02:31:17 I would just need the level shifter for the extra pins to transfer the GPIO signals w/ GND and vdd_5v? Jun 12 02:31:20 yes, the analog pin for the keypad would require different treatment, if you want to use that Jun 12 02:31:28 Okay. Jun 12 02:31:42 sys_5v you mean Jun 12 02:32:19 Well. This person explained that vdd_5v is receiving power from the BBB vdd_5v. Jun 12 02:33:35 So: vdd_5v LCD <---> vdd_5v BBB Jun 12 02:33:40 sys_5v BBB Jun 12 02:33:50 No. vdd_5v. Jun 12 02:33:59 But, if it must be, I think this fellow may be wrong. Jun 12 02:34:06 you asked earlier which one to use, I said sys_5v Jun 12 02:34:15 vdd_5v is meant as input to the bbb, to power the bbb itself Jun 12 02:34:42 although it can also be used to draw power if the bbb is powered via the barrel connector (but not if powered via usb) Jun 12 02:34:53 Oh! Jun 12 02:34:59 That may be it. Jun 12 02:35:31 Luckily, I did not use the vdd_5v instead or my LCD may have gone boinkers. Jun 12 02:35:40 ? Jun 12 02:36:01 I used P9_07 instead of P9_05. Jun 12 02:36:21 P9_07 = sys Jun 12 02:36:28 .... yes, and/ Jun 12 02:36:29 ? Jun 12 02:36:47 Ha. Let me try w/ the pot and the P9_05 pin. Jun 12 02:37:05 ?? Jun 12 02:37:12 I know, I know. Jun 12 02:37:18 But...it will not hurt, right? Jun 12 02:37:30 it very easily can yes Jun 12 02:37:37 I mean...it either works or it does not. Jun 12 02:37:38 Oh? Jun 12 02:38:00 What could go incorrectly? Power failure or erase of my image? Jun 12 02:38:25 Or...backdraw of electricity where it does not belong? Jun 12 02:38:28 I don't know if the protocol includes any outputs from the lcd, but if so it could destroy the BBB. even if the pins are merely pulled up to 5v rather than driven, it may damage the BBB in the long term Jun 12 02:38:32 bzzt. bzzt. Jun 12 02:38:45 Oh. Jun 12 02:39:00 Okay. I better be careful. This LCD was only $4.00. Jun 12 02:39:20 I got it attached to the BBBW, too. Jun 12 02:39:22 Yikes! Jun 12 02:39:52 Do you want to see the pinout of what is supposed to happen? Jun 12 02:40:44 Come on! Jun 12 02:41:12 I will use pastebin soon. Jun 12 02:41:14 Please hold. Jun 12 02:41:35 instead of asking you could just have provided a link Jun 12 02:41:44 Oh yea. Hold, hold, hold. Jun 12 02:44:53 https://pastebin.com/0UE9Ri1Z is the software from Kiran. Jun 12 02:45:08 It just shows the pins for output. Jun 12 02:47:20 rcn-ee[m]: sorry for the delay, but that build you asked me to test the other day (bone-eMMC-flasher-debian-9.9-console-armhf-2019-06-02-1gb.img) seems to work fine Jun 12 02:49:32 set_: this looks like complete nonsense Jun 12 02:49:43 Serious? Jun 12 02:50:15 Even w/ the pot being populated like I discussed. Jun 12 02:50:41 backlight anode/cathode aren't gpios, they're power terminals, and the board you cited doesn't have those pins in the first place, it has an integrated backlight driver Jun 12 02:51:01 Hmmm. Jun 12 02:51:03 Okay. Jun 12 02:58:41 dabbler: thanks for testing! ;) **** ENDING LOGGING AT Wed Jun 12 03:00:27 2019
