**** BEGIN LOGGING AT Thu Oct 04 03:00:02 2018 Oct 04 05:38:57 is it on github? Oct 04 06:41:22 hello Oct 04 06:41:40 can i know how to get the address inside of mmc Oct 04 06:49:13 what do you mean by "address inside of mmc"? Oct 04 06:53:39 when i want to write to mmc in uboot Oct 04 06:54:03 i need to specify the blk# Oct 04 06:54:27 ah, no clue about writing to eMMC from u-boot Oct 04 06:54:40 could always ask on the u-boot irc channel Oct 04 06:56:26 ok thanks Oct 04 09:42:38 hi. I am trying to connect my BBBW with wifi router using connman. I can see ssid in services on connmanctl adn when i am trying to connect I get "Agent ReportError wifi_506583d7f8b0_46694f532d3759573147_managed_psk connect-failed Agent request cancelled by ConnMan Error /net/connman/service/wifi_506583d7f8b0_46694f532d3759573147_managed_psk: Operation aborted" Oct 04 09:42:51 Please help on this as it is happening since few days Oct 04 09:53:46 any one on connman issue Oct 04 09:53:46 ?? Oct 04 09:58:47 have you tried connecting it to a different WiFi Access Point? Oct 04 11:40:02 ?? Oct 04 12:52:28 ayjay_t: not yet Oct 04 14:46:18 Hi everyone! Oct 04 14:46:33 I have a couple questions about the beagleboard x15.... Oct 04 14:47:23 just ask, someone might answer, or not Oct 04 14:48:09 I had a bad experience with a banana pi where I could only install their linux image. On the x15 can I install ubuntu straight from the ubuntu iso (without needing a custom kernel to get it to work on the x15)? Oct 04 14:48:48 mozzer: if in doubt, no Oct 04 14:49:09 mozzer: linux on arm generally is a bit complicated when it comes to board support. Oct 04 14:49:48 mozzer: but the sources to rebuild x15 images should all be available, including proper openembedded support Oct 04 14:50:11 (whereas i doubt that canonical rolls and actively supports a x15 image) Oct 04 14:51:32 ah ok. so it sounds like hopefully a better experience than the banana pi. Banana pi boasts this functionality and that functionality but then when you install their image and it doesn't work you realize what they REALLY meant was that it could, in theory, support certain functionality but not yet. lol Oct 04 14:51:53 Are there cases available for the x15 or re people printing their own? Oct 04 14:54:58 mozzer: it's definitely not like those chinese boards where you have some heavily patched version of an ancient kernel and that's it. TI both actively maintains their kernels and works on mainlining their stuff Oct 04 14:56:59 great. thank you! Oct 04 15:00:45 though it looks like armbian got some vanilla linux kernels going on some of the banana boards Oct 04 15:27:13 In the official image, accesses to ddr are Normal, and accesses to devices are Strongly-ordered? Oct 04 15:28:44 Strongly-ordered in userspace (uio and /dev/mem), Device in kernelspace Oct 04 15:34:10 And ddr normal in both userspace and kernelspace? Oct 04 15:34:50 of course Oct 04 21:03:27 Am I allowed to use a dc-dc converter for making the BBB run by barrel jack? Oct 04 21:03:34 via battery? Oct 04 21:03:53 I typed allowed. I should have used another word. Oct 04 21:05:02 Anyway...would the BBB understand? battery --> terminal --> wiring --> barrel jack = POWER! Oct 04 21:06:03 B/c the volage the BBB takes is 5v from barrel jack and I can use the dc-dc converter to convert DC input to the BBB via barrel jack. Oct 04 21:06:04 ... Oct 04 21:06:09 Does this sound correct? Oct 04 21:06:24 believe in yourself, set_ Oct 04 21:06:31 Okay! Oct 04 21:06:59 bbb is oblivious. All it knows is that there is a good source of juice available at it's power jack. Oct 04 21:07:06 I have the MotorCape attached. This is easy but w/out my barrel jack, the board does not communicate w/ my MotorCape. Oct 04 21:07:08 Right! Oct 04 21:07:41 Okay, onto to "bluer" skies. Oct 04 21:08:15 well you need to provide power via barrel or usb anyway, and both require 5V Oct 04 21:08:36 what will the next version of bbb be? POE? Will they put back my hardwire enet port AND have wireless? Oct 04 21:08:57 Right-o but zmatt: remember that the MotorCape and BBB cannot communicate w/ sys_5v from the BBB input. Oct 04 21:09:16 Running by itself, sorry. Oct 04 21:09:25 I'm aware of that. I'm just saying that the motorcape's (slightly annoying) requirement to use the barrel jack instead of usb doesn't change the fact you need to provide 5V one way or the other Oct 04 21:09:47 Okay. So, a dc-dc converter should be a route to take. Oct 04 21:09:49 Okay. Oct 04 21:09:54 motors and gizmos like that pull too much. They need their own source of juice anyways. Oct 04 21:10:11 Snert__: motor has a separate supply at a much higher voltage Oct 04 21:10:15 I actually found some 5v batteries. Oct 04 21:10:18 ok...good. Oct 04 21:10:20 the 5v is used purely for logic Oct 04 21:10:30 Right-o! Oct 04 21:10:37 which is why it's so bizarre they're drawing it from vdd_5v instead of sys_5v Oct 04 21:11:28 ... Oct 04 21:12:05 That is a good question, why is the communication using vdd instead sys for powering while communicating? Oct 04 21:12:20 Hey! There must be a reason. Oct 04 21:12:29 you'd need to ask whoever designed it Oct 04 21:12:44 I should. I will go and ask the forum they have up and running. Oct 04 21:12:54 Maybe someone will reply. Oct 04 21:13:23 Do you think it may have something to do w/ EEPROM? Oct 04 21:13:40 The chip lasts longer w/ memory on it? Oct 04 21:14:01 Or...they do not want people rewriting the memory on it? Oct 04 21:14:17 ... Oct 04 21:14:18 you're talking nonsense again Oct 04 21:14:20 That makes sense to me. Oct 04 21:14:24 Oh. Oct 04 21:14:26 Sorry. Oct 04 21:14:46 a blank chip has lots on it. All zeros. Oct 04 21:14:54 (the eeprom is powered by 3.3v anyway, 5v is purely for the motor driver) Oct 04 21:15:01 Oh. Oct 04 21:16:15 GHI made the thing. I am off to their forum. Sorry to bug you people. Godspeed! Oct 04 21:16:32 Snert__: more commonly all ones actually Oct 04 21:28:28 Okay. I got the odd questioning on their forum. Oct 04 21:28:43 I think I asked correctly. I will have to wait and see their response. Oct 04 22:52:37 anyone else seen a brand new BBB come out of the anti-static bag in a compromised state? Oct 04 22:52:39 I did. Oct 04 22:53:00 ? Oct 04 22:53:11 define "compromised" Oct 04 22:53:14 saw tons of enet activity.....installed etherape.... and..... Oct 04 22:53:22 o.O Oct 04 22:53:44 lo and behold....it was talking to 50-100 addresses all in 1 block.....owned by a chinese hosting company. Oct 04 22:53:52 that sounds really serious Oct 04 22:53:56 jkridner: ping Oct 04 22:53:58 I wiped the fucker. Oct 04 22:54:44 kinda makes sense. What better way to expand your botnet than to preload things like BBB with malware. Oct 04 22:55:11 if I hadn't installed etherape and had a look at what it was doing I mighta never known. Oct 04 22:55:55 it was me that broke the seal on the antistatic bag. Oct 04 22:56:14 so it was virgin...direct from WhateverBuilder Oct 04 22:57:37 iirc it came from adafruit but I can't remember zactly cause I waited 6 months to turn it on. Oct 04 22:58:15 it may not have been. I hate to smear adafruit accidentally. Oct 04 23:01:14 wish I had taken a pic before I wiped it. Oct 04 23:01:50 it was talking to 50-100 addresses .... all the addresses had the absolute same 1st 2 octets. Oct 04 23:02:08 which looked up as a chinese hosting company. Oct 04 23:31:26 about the PRU: what is the difference between LDI and MOV ?? Oct 04 23:35:25 ldi loads a 16-bit constant into a register. mov is a pseudo-instruction that (when used in the form mov reg, const) gets encoded into one or two LDI instructions Oct 04 23:36:14 mov also has a register-operand version (mov reg, reg) Oct 04 23:37:12 (which is actually an AND instruction) Oct 04 23:38:31 thanks Oct 04 23:50:38 can't found a good cheatsheet of PRU assembly out there Oct 04 23:56:04 http://processors.wiki.ti.com/index.php/PRU_Assembly_Instructions Oct 04 23:58:32 good enough Oct 05 01:50:48 how is the synchronization between two PRUs? semaphores in the shared memory? interrupts? Oct 05 02:14:03 throwback to when I did this: https://imgur.com/gallery/6JTec Oct 05 02:20:36 lovely Oct 05 02:26:40 And your Hakko brings me confidence **** ENDING LOGGING AT Fri Oct 05 03:00:01 2018
