**** BEGIN LOGGING AT Sun Nov 16 03:00:00 2014 Nov 16 03:04:27 how are we today? Nov 16 03:07:25 i was wondering if anyone would be available for a little assistance as to why my frankenlaptop isnt properly interacting with my lapdock display Nov 16 03:08:35 there is a lot of information on google for the atrix lapdock. It seems I made a mistake in purchasing the successor model, aka lapdock 100 Nov 16 03:09:40 i have a beaglebone black running the debian distribution, finishing upgrades atm. Nov 16 03:17:53 I was hooking up a h bridge (MC33926, http://www.pololu.com/product/1212) and may have messed up the pinout (ground to vdd and vdd to ground), now when i plug it in the power led flashes and then nothing happens, same when i hit the power button, seem's likely its bricked (https://groups.google.com/forum/#!msg/beagleboard/FGeL6jzOcB0/GjeNngPUUPIJ) but is there anything else i can do? Nov 16 09:43:08 is it even possible to brick a beagle? just pop in an sdcard and hit the reset button, no? Nov 16 10:11:45 <_av500_> yes Nov 16 10:11:59 <_av500_> hold the user boot button and cycle the power in fact Nov 16 13:05:12 Hi, I have connected a 5V FTDI cable on debug port and all is working correctly Nov 16 13:05:33 looking the schematic there is SN74LVC2G241 Nov 16 13:05:38 that is a buffer Nov 16 13:06:02 I was luky or is the buffer that translate 5V to 3.3V ? Nov 16 13:06:20 The board is not damage ad is working correctly Nov 16 13:27:19 gmg: 3.3V is what you are supposed to use and 5V can damage things Nov 16 13:29:53 tbr: your answer is that because you have read the SN74LVC2G241 datasheet and look the circuit or is only a your thnk ? Nov 16 13:30:36 gmg: it's because I know what the BBB expects from reading the SRM Nov 16 13:31:33 for my opinion the SN74LVC2G241 is making a level translater and it makes the debug port 5V compliant Nov 16 13:33:03 SRM page 90 Nov 16 13:40:17 tbr: I agree with you, but looking the schematic and the datasheet of SN74LVC2G241, the eader is 5V compliant without problems Nov 16 13:43:18 gmg: that I don't know. maybe they were especially careful because they knew how users are. Nov 16 13:50:47 I need some infos about an BeagleBoard device. I need to run a Processing code, which plays some full HD videos following the reception of a signal on a serial port (such as Arduino's TX and RX). Does anybody knows if any BeagleBoard product supports this video playing without lagging? Nov 16 13:53:49 fullHD - not that I know of. Maybe that X15 thing Nov 16 13:55:33 The Xm?? Nov 16 13:55:55 no Nov 16 14:01:01 tbr: your can be a good interpretation... Nov 16 14:04:08 so I have to wait February? Nov 16 14:26:00 matteomaria38: or chose one of the many other boards that are floating around. (don't look at panda, that's dead) Nov 16 14:43:36 tbr: I have verified on TI web site and the SN74LVC2G241 can be used as level shifter from 5V to 3.3V, so the debug port (only the debug port) is 5V compliant Nov 16 14:44:21 so likely a protective measure Nov 16 14:44:21 tbr: that means you can use TTL232R-5V or TTL-232R-3V3 cable for that Nov 16 14:45:39 tbr: so I'm not luky, the bbb developers has made (another time) a good work Nov 16 16:04:20 hey im new here and i have an issue i cant seem to find a way around. the 3rd pin on my sd reader on my bbb broke off the other day and i need to flash my bbb. is there any other way to flash my bbb than the usual sd card emmc flash method Nov 16 16:31:27 *phew* I thought I had fried my BBB - /dev/ttyO4 wasn't doing anything, not even with with a simple wire between pin 13 and 11. Nov 16 16:32:00 Turns out my USB power supply went from doing 5V to suddenly doin 2.8V with a lot of ripple, surprised the BBB even boots with that. Nov 16 16:43:32 hello Nov 16 16:44:06 hi Nov 16 16:44:14 i am searching for some help with me beaglebone black Nov 16 16:44:49 after a halt command in ssh i cannot power it on Nov 16 16:45:19 it works perfectly plug in USB but with AC adapter nothing appen Nov 16 16:45:26 Not even if you unplug and plug it all back in? Nov 16 16:46:26 i've plug and unplug AC adapter, i've test AC adapter he's ok, i've let bbb unglug during 2hours but nothing work Nov 16 16:47:04 I'n not quite sure I understand your problem yet. 1) Does your BBB still work, can you turn it on or is it dead? Nov 16 16:47:49 my BBB work perfectly on USB but doesn't work when i plug my AC adapter Nov 16 16:48:22 i only have a flash on the led power when i push power bouton Nov 16 16:48:42 Ok. Have you measured the output power of your AC adapter? Nov 16 16:49:01 yes he's good Nov 16 16:49:05 Curiously, I had a power adapter die on my just 10 minutes ago, I really though I had killed my BBB but it was just a crappy PSU. Nov 16 16:49:07 hi Nov 16 16:49:20 hi Nov 16 16:50:03 i've test my AC adapter with a multimeter and he's ok Nov 16 16:50:52 Even under load? Nov 16 16:52:08 i don't know what does that mean Nov 16 16:52:38 Does it stay at 5V when it has to deliver current? Nov 16 16:53:25 has anyone ever seen spi controllers in embedded linux boards which are not capable of doing full duplex transfers? if i get the datasheet of a mt7620/wrtnode cpu right, it seems so... maybe i have to switch back to the more expensive bbb... Nov 16 16:54:03 i don't know where put my multimeter to test that on the BBB Nov 16 16:54:17 the 5V pin Nov 16 16:54:19 and gnd Nov 16 16:54:25 have a look at the datasheet Nov 16 16:54:45 Rotti: no, he means how to test it while the BBB is running. Nov 16 16:55:08 yes when BBB is running Nov 16 16:55:09 Peanut: on p8/9 there should be a 5v pin, too Nov 16 16:55:31 p9.5/6 Nov 16 16:55:43 mabro: You could test with a resistor otherwise, or you can test on P8 or P9. Nov 16 16:55:45 or was it 7/8= Nov 16 16:55:56 i'll read datasheet to find them and test with my multimeter Nov 16 16:56:20 Rotti: P9 1 and 2 are gnd, 3 and 4 are 3.3 V, 4 and 5 are Vsys I think and 6 and 7 are 5V. Nov 16 16:56:49 Peanut: yes, but there are sys_5v and vdd_5v... Nov 16 16:56:53 its so sad, i've used my BBB 30mn ... Nov 16 16:56:55 The problem mabro is having is that his BBB works from USB, but not from the 5V input anymore. Nov 16 16:56:57 probably the latter one (5/5) Nov 16 16:57:27 and i don't have another 5V AC adapter Nov 16 16:57:41 mabro: do you have some resistors? Nov 16 16:58:04 no sir i am a total noob here Nov 16 16:58:19 do you have a soldering iron? Nov 16 16:58:21 So the question is whether his BBB is dead, or his 5V supply dips as soon as he tries to start it up. Nov 16 16:58:31 you can apply 5v on the pin header, too Nov 16 16:58:48 cut an old usb cable and use the red and black wire Nov 16 16:59:49 i used vdd_5v (p9.5 and .6) Nov 16 17:00:01 i am affraid to kill my BBB i am not accustomed to electronic Nov 16 17:00:24 Then please be careful, mabro. Nov 16 17:01:01 yes i won't do thing that i don't understand without asking Nov 16 17:01:24 brb 2mn i'll search if i don't have another AC from a ADSL modem Nov 16 17:01:47 AC? I hope you're using DC! Nov 16 17:08:31 i've found a 5V power supply USB, do you think i can use it ? it was for a phone Nov 16 17:09:00 mabro: that should work, might want to test it first with the meter Nov 16 17:09:24 yes Nov 16 17:09:40 if i don't find another power supply i'll test that Nov 16 17:11:15 amazing ! Nov 16 17:11:42 i've plug again my power supply and my BBB start ! Nov 16 17:12:14 i still don't understand Peanut but thanks a lot for you help Nov 16 17:12:48 Maybe you had a short and it went into protection for a while? Nov 16 17:14:03 i don't know i've unplug my BBB and my power supply during few hours Nov 16 22:01:00 I'm trying to run some regular ARM assembly code on the beagleboard black (rev C) but it seems to run in thumb2-mode even though PC has the low bit clear - Is 32-bit ARM code not supported on BB? Nov 16 22:33:02 solved it Nov 17 00:23:21 hello i am student enginering mechatronic Nov 17 00:23:29 I am noob program beagleboard xm Nov 17 00:24:00 I want know if my beagleboard load sucesfully angstrom distribution Nov 17 00:24:06 Anybody can help me? Nov 17 00:24:33 What indications from leds i should see **** ENDING LOGGING AT Mon Nov 17 03:00:00 2014
