**** BEGIN LOGGING AT Sat Jul 05 02:59:59 2014 Jul 05 03:59:41 Hello, all! Jul 05 04:05:29 I read in the wiki: "We have been noticing a very small number of boards ... where the LED flashes and the board does not power up. [T]his appears to be an instance where the PMIC does not power down the processor in the right order due to the violent removal of the power cables, either USB or DC." This sounds like the issue I'm having. The board works when used with the USB power, but not with the power plug. The LED used to flash Jul 05 04:05:39 The LED used to flash briefly when the plug was applied, but now only lights up for the USB. The wiki didn't say how -- or if -- it can be fixed. Any ideas? Jul 05 04:06:19 BBB, rev 3, by the way. Jul 05 04:06:27 er, rev C Jul 05 04:31:34 Anybody else's BBB rev C work via USB power but not via power plug? **** BEGIN LOGGING AT Sat Jul 05 04:42:45 2014 Jul 05 06:52:42 hello all Jul 05 06:54:34 Question 1 : How can we use Beaglebone Black Rev C image file (of debian) to work under VMWARE... for testing and stuff because i do not like to continuesly erase and restore the eMMC... Jul 05 07:10:04 Hello sorry for bad internet connectionetion Jul 05 07:10:12 is any body answered my question ? Jul 05 07:10:30 Question 1: How to use BBB debian image under VMWARE Jul 05 07:17:22 anybody home ? Jul 05 07:33:58 <_av500_> no Jul 05 07:34:13 <_av500_> I dont think VMWARE supports ARM Jul 05 07:34:18 <_av500_> you could use qemu Jul 05 07:34:38 <_av500_> and you dont need to use emmc at all, use an SD card Jul 05 07:56:44 just boot off a uSD instead of flashing the emmc Jul 05 07:57:04 that ^^ Jul 05 08:03:27 Hey sorry didn't reply because browsing for solution Jul 05 08:04:06 how can you achieve it via qemu @@_av500 BobCat Jul 05 08:04:28 i have used qemu but to very basic and certain extent Jul 05 08:05:14 what do you need qemu? Jul 05 08:05:17 ahy Jul 05 08:05:20 why Jul 05 08:05:22 Please also know that i have more question too but will go sequence wise to not blot the channel.. Also it is not very good for presentation too :) Jul 05 08:05:36 i mean to test the .img (emulate it in qemu) Jul 05 08:05:46 i got you point on using SD card instead Jul 05 08:05:57 just test it on the BBB Jul 05 08:06:09 and i do thing it is nice but you will still require the HARDWARE BBB Jul 05 08:06:30 so i wanted a solution totally based on Software side... so even if i m travelling i can work on it... Jul 05 08:07:13 btw using SD card is good too... (booting from it) .... even than if you have any idea over the emulation in software please do advice... Jul 05 08:07:17 fine, qemu can run an ARM image Jul 05 08:07:46 So what exactly i have to follow i mean shall i just open the img file in it and it will boot ? Jul 05 08:07:58 or will i have to do certain config to make it happen Jul 05 08:09:05 I can't help you with qemu Jul 05 08:09:22 okay i will try to understand it... brb Jul 05 08:09:50 Oh and i forgot... thank you for answering... will be back Jul 05 08:28:08 Hi again i think it will take some time to understand how it work under qemu but i guess it is easy.. Jul 05 08:28:26 Now next question Jul 05 08:29:09 I recently purchased my BBB rev C from adafruit. While testing the lan/internet connection i was only getting 5kb Jul 05 08:29:37 same i tried with INTERNET over USB and it was giving 500kbps (which is max speed i have) Jul 05 08:29:51 So my question is Jul 05 08:30:31 Question 2 : Why am i getting 5kb on LAN connection (debian OS did apt-get update, upgrade already) Jul 05 08:55:49 Sorry i have a bad connection at home.... Because of which frequent disconnection Jul 05 08:56:14 My question again why am i getting 5kb max speed via LAN connection Jul 05 09:51:50 bilalinamdar, I guess you answer yourself Jul 05 10:19:13 bilalinamdar, it might be your connection... Jul 05 11:44:11 oh sorry mkad for late reply Jul 05 11:44:18 i was sleeping Jul 05 11:44:27 Actually currently i am at home Jul 05 11:44:38 but i work on bbb in the office Jul 05 11:44:44 and i have good connection in office Jul 05 14:16:01 Hi Jul 05 14:16:11 I have a question regarding beaglebone Jul 05 14:16:28 Anyone who can help me with it? Jul 05 14:19:13 just ask and wait Jul 05 14:21:07 \I wanted a MCU that can control 24bit LCD capacitive touchscreen and talk to bluetooth module via UART. I was interested in SOM that can run Andriod for UI Jul 05 14:21:22 Since beaglebone can do all of the above. I wanted to use it Jul 05 14:22:39 however it is good for prototype. But since i am looking into mass manufacturing, I need the board to be slim and I will want to develop my own PCB Jul 05 14:22:45 is it possible with beaglebone? Jul 05 14:31:34 Mehul, someone is making beagle based multirotor drone pcb Jul 05 14:31:43 using similar components just less ram Jul 05 14:31:58 Mehul, so I guess it should be Jul 05 15:11:55 hmm Jul 05 15:12:16 I have a question, I try to read whoami register from imu Jul 05 15:12:21 https://github.com/mashu/beagledrone/tree/master/src Jul 05 15:12:27 but it does not work Jul 05 15:12:37 I get nothing Jul 05 15:14:15 any help what might be wrong? Jul 05 15:25:18 hey folks, so I was having issues with 2 things... Jul 05 15:25:44 1. My bbb seems to shut off after about 10 minutes Jul 05 15:26:02 so is there an "auto-off" feature that I can disable or what's up? Jul 05 15:26:43 2. I've updated my /etc/network/interfaces file to include "auto wlan0" and all the proper configs but when I boot up I still have to call "sudo ifup wlan0" for the wireless to come up Jul 05 15:26:52 so is there a way to fix that? Jul 05 15:27:03 I'm running the latest debian from bbb site Jul 05 15:30:30 mkjackson, maybe other software is overriding your config ? Jul 05 15:31:05 mkjackson, my bbb runs on usb cable connected to laptop since yesterday with no issues also debian jessie Jul 05 15:31:39 how could I be sure that's what's happening? Jul 05 15:31:40 :-( Jul 05 15:32:50 mkjackson, dunno but the file interfaces can be override by network-manager or wicd or probably many other network managing deamons Jul 05 15:33:28 my bbb is using wicd Jul 05 15:33:48 but I havent read how to configure it to set up wireless automatically Jul 05 15:34:28 when it comes to turning off, I have no clue, that does not happen to me Jul 05 15:34:38 you could check logs Jul 05 15:35:43 mkad: ah ha! so wicd is running on my box as well, I suppose that wicd and networkmanager do not share config files... Jul 05 15:35:44 :-/ Jul 05 15:36:06 i dont know, I use on my laptop network-manager and on bbb wicd Jul 05 15:36:31 and for why it turns off (if it does) check logs Jul 05 15:37:00 might potentially give you some clues Jul 05 15:45:49 why is everything written on the beagle for windows? :P gah frustrating hunting down how to do certain things when on a unix Jul 05 15:46:53 suppose I could just use dd Jul 05 15:47:05 you usually can Jul 05 15:48:29 also if I go to ubuntu can I still ssh over usb? Jul 05 15:48:34 I don't actually own a monitor Jul 05 15:49:37 if in double qemu the image and apt-get install openssh-server Jul 05 15:50:45 As I'm new to beagle still, qemu? Jul 05 15:51:17 so I have to build my own image through qemu? Jul 05 15:52:33 ok..you better don't do that, stay with the default image, it should do Jul 05 15:53:47 well many of the things I do are in ruby or python, though this project is music/gps/sdr for my truck Jul 05 15:55:17 I honestly have no issues building something if that's the route I have to go. I can easily flash things back and forth if I do have a legit way of testing Jul 05 16:39:27 ok, so now I have auto-connecting wifi Jul 05 16:39:39 however the machine still shuts down consistently after 15 minutes Jul 05 16:39:59 mkad: you mentioned log files Jul 05 16:41:24 mkad: do you know which ones would likely help me with this craziness? Jul 05 17:13:28 hm Jul 05 20:05:13 ok, so fixed everything except for the rebooting issue but here it is: I've never stopped booting from the SD card and so when I've been SSH'ing into the board from my terminal, the gui has been booting up and flashing the emmc and rebooting in 15 minutes Jul 05 20:05:33 so I thought to myself, "then the emmc no longer needs to boot from the SD! let's take it out!" Jul 05 20:05:52 but no boot without the sd card... is this normal when using the SD card? Jul 05 20:06:17 I thought the idea of flashing the EMMC was to push the image to the EMMC and leave the SD for general purpose stuff :-/ Jul 05 20:11:29 usually if the emmc flashing is successful .. you can take the uSD out .. and its fine .. but sounds like something didn't go right for you Jul 05 20:11:54 I'd be very suprrised if it flashes in 15min ... Jul 05 20:12:12 unless jkridner and the team have managed something pretty flash :D (Excuse the pun!) Jul 05 20:12:44 yeah, there are some errors coming through the UART regarding python Jul 05 20:12:45 :-/ Jul 05 20:12:55 I guess I can try to flash one more time Jul 05 20:12:58 see what happens Jul 05 20:13:05 grumble grumble Jul 05 20:14:05 burn a clean copy of the flasher image if I were you Jul 05 20:14:23 from the beagleboard.ogre site .. no wait .. 'org' :D Jul 05 20:15:48 yeah, I've verified the md5 on the debian emmc flasher image I torrented down Jul 05 20:15:59 using pi filler (osx) to flash onto a new sd now Jul 05 20:16:11 you can't verify that it writes it to the card correctly though ;) Jul 05 20:16:16 some cards are picky Jul 05 20:22:47 i do vaguely recall hearing about something that dramatically improved the flashing speed Jul 05 20:23:48 * vagrantc wonders what "pi filler" does. Jul 05 20:24:58 I am trying to read from i2c bus but I always get number 7 :( Jul 05 20:25:00 in c++ code Jul 05 20:25:09 and when I use i2ctools value returned is correct Jul 05 20:25:10 ;/ Jul 05 20:32:46 mkad .. I would suggest your code is wrong :P or doesn't have the same permissions as you .. etc. Jul 05 20:33:17 vagrantc .. guess its something similar to 'dd' .. though I thought you could use *nix commands in OSX Jul 05 20:33:30 vagrantc .. could be something as simple as block size Jul 05 22:00:40 Does anyone know how many write cycles emmc can endure ? Jul 05 22:01:03 I am developing something /recompiling saving every change in file... Jul 05 22:01:09 does that matter? Jul 05 22:08:26 obviously the number of writes per cell is not limitless, but what that limit is I do not know Jul 05 22:09:36 I guess it partially depends on how full it is Jul 05 22:10:21 as the fewer extra cells the lower your mtbf Jul 05 22:14:05 actually mtb is probably relatively constant, the number of failures before it is catastrophic is what changes Jul 06 01:32:09 helllo Jul 06 01:41:03 mkad: Then there is also the disk cache in Linux, that somewhat reduces flash wear (at the risk of data loss when powered off suddenly) **** ENDING LOGGING AT Sun Jul 06 02:59:59 2014
