**** BEGIN LOGGING AT Tue Mar 14 03:00:03 2017 Mar 14 03:40:07 Hi there. I'm having troubles figuring out how to expand my eMMC install of ubuntu to the SD card to get more space. I've read and followed a couple items on eLinux but not getting anywhere useful. Is there a good writeup on this anywhere? Mar 14 06:43:16 hello Mar 14 06:43:24 may i know what can i do with beaglebone? Mar 14 13:58:12 how standard are cheap LCD screens? I broke one which I want to replace, only info I got is it's got 9 pins and a sticker on the back that says COG-VLFM1764-03 Mar 14 14:00:02 it indeed exists as an obscure reference but I coudln't find one to buy, maybe I can find an equivalent part? Mar 14 16:30:05 Hi Mar 14 16:30:19 I am trying to get started with programming the PRUs Mar 14 16:30:26 I am following instructions on this page Mar 14 16:30:35 http://boxysean.com/blog/2012/08/12/first-steps-with-the-beaglebone-pru/ Mar 14 16:30:58 However, after executing ./PRU_memAccessPRUDataRam Mar 14 16:31:21 it gives me an error " INFO: Starting PRU_memAccessPRUDataRam example. prussdrv_open open failed" Mar 14 16:31:30 How can I solve this? Thanks ! Mar 14 16:32:04 Can i knw if anyone used pulse sensor for BBB> Mar 14 16:32:05 ? Mar 14 17:07:23 zmatt: I wonder, what do you think will happen if you power down the DDR DPLL and not have the memory in self-refresh? Mar 14 17:16:26 exponential decay of your stored data Mar 14 17:17:04 (and undefined behaviour due to ddr3 protocol violation) Mar 14 17:17:18 that's assuming it will let you, but I guess those pll power override controls will) Mar 14 17:22:29 zmatt, do you know how standard LCD displays are? I broke one and failed to find an exact replacement online Mar 14 17:23:09 das_: 2x16 or 2x20char are almost always based around clones of the Hitachi LCD driver. Mar 14 17:23:24 And there are 4line versions Mar 14 17:24:40 it's a 4 line Mar 14 17:24:47 has 9 pins Mar 14 17:26:25 sounds about right Mar 14 17:26:45 14/15 includes backlight power :D Mar 14 17:27:25 backlight was built in a strange way in this device Mar 14 17:28:18 2 leds on the PCB, light going horizontally, reflected on a white plastic case around the screen Mar 14 17:38:42 yeah I've seen similar if I don't even have one :) Mar 14 17:39:09 you shuold be fine .. small chance of minor modifications Mar 14 17:39:29 there are sometimes some boot/config issues .. but the basic command syntax is the same Mar 14 17:43:59 ver|laptop: alright I'll look for one on farnell tomorrow morning, thanks Mar 14 17:46:51 :) Mar 14 18:39:35 zmatt: there's definitely something fishy about the pll powerdown, because if I omit it and only idle the MPU DPLL, the M3 doesn't catch a busfault Mar 14 18:39:59 zmatt: idle -> bypass Mar 14 18:40:13 zmatt: sorry for not being precise Mar 14 19:51:16 thinkfat: hmm, does this also happen with no debugger attached? Mar 14 19:55:02 hum, that hwmod_disable(HWMOD_IEEE5000); in a8_cpuidle_v2_handler definitely deserves an explanatory comment Mar 14 19:55:21 lol @ commit 1d5237fe42b5 Mar 14 19:55:51 he's confusing N2 with N Mar 14 20:08:23 zmatt: good question Mar 14 20:09:16 zmatt: I haven't yet seen any special behaviour of the M3 when the debugger was attached, so I assumed it was not causing any harm Mar 14 20:09:47 zmatt: btw which core id does the M3 have in icepick? Mar 14 20:10:17 zmatt: because I think the tap-enable function of oocd also writes to 0x60 when it enables the M3 tap Mar 14 20:10:25 zmatt: that somehow looks wrong Mar 14 20:10:50 it doesn't have one Mar 14 20:11:16 since the m3 has its own private TAP, this is also its core register Mar 14 20:11:27 so 0x60 is correct? Mar 14 20:11:29 no Mar 14 20:11:37 ah, right Mar 14 20:11:39 0x60 is the Cortex-A8 core register Mar 14 20:11:46 since the cortex-a8 doesn't have its own TAP Mar 14 20:11:56 it uses the tap control register Mar 14 20:12:21 * thinkfat needs to find the icepick documentation Mar 14 20:12:33 icepick-c docs is still mostly right Mar 14 20:13:07 but they were running into limitations of the debug TAP == processor assumption Mar 14 20:13:28 because of memory-mapped debug Mar 14 20:15:17 hence the addition of the core registers for processors with no TAP, to still have the remaining ICEPick controls normally found in the debug TAP register Mar 14 20:36:03 zmatt: I found my copy of spruh35 Mar 14 20:41:06 yea, also check dm37xx TRM Mar 14 21:10:44 zmatt: hmm, I'm wondering what happens to the core dpll in DS1. I hope it doesn't get shut down somehow Mar 14 21:11:32 zmatt: that would certainly explain why the M3 doesn't do well when trying to power up the other dplls Mar 14 21:18:58 zmatt: but when looking at the core dpll diagram, there isn't really a way for the core dpll to not output a clock, as long as the master oscillator is on Mar 14 22:11:50 GRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR libreoffice is the biggest PoS ever Mar 14 22:16:48 ds2: ^^ I have the same Mar 14 22:22:36 @%@#$@#$@#$@# PoS ignores your settings Mar 14 23:03:51 question, does anyone use the Beagleboard project's bug tracker at bugs.elinux.org? Mar 15 01:38:04 @wmat now i'm curious, does anyone? Mar 15 01:38:16 or maybe i don't need to type the @, i've never addressed an op before. i feel like i'm on twitter now Mar 15 02:27:44 lol Mar 15 02:32:10 so i guess the am335x USB can emulate more than one USB device Mar 15 02:33:06 that's pretty cool i'm going to use that Mar 15 02:58:57 Hello! i want to ask that if we could use bonescript/python to use beaglebone Black timer. If yes, then how :) **** ENDING LOGGING AT Wed Mar 15 03:00:02 2017
