**** BEGIN LOGGING AT Sat Jun 06 02:59:57 2020 Jun 06 08:37:20 I am not able to connect 192.168.7.2:3000 directly ? I am getting ip error Jun 06 08:37:26 What to do Please help me Jun 06 08:38:07 what are you trying to do? Jun 06 08:43:42 Open the cloud9 of beaglebone black Jun 06 08:43:56 It is showing the error Jun 06 08:43:59 is it running? are you using the correct IP address? Jun 06 08:44:09 no it is not running Jun 06 08:44:21 I am using 192.168.7.2 address of the beaglebone Jun 06 08:44:56 well, start it then Jun 06 08:45:03 not working Jun 06 08:45:12 it is showing the error Jun 06 08:45:22 connection was interrupted Jun 06 08:46:25 can you connect to some other service on the beagle? Jun 06 08:46:31 ssh or whatever? Jun 06 08:46:42 yes ssh is working fine on the terminal Jun 06 08:46:49 I am using Linux Jun 06 08:47:11 you can ssh to the beagle using ip address 192.168.7.2? Jun 06 08:47:19 yeah Jun 06 08:47:37 but cloud9 is not working on the browser that is the main issue Jun 06 08:48:01 probably because it isn't running then Jun 06 08:48:07 ssh to the beagle and start it Jun 06 08:48:31 Yeah but what about cloud9 Jun 06 08:48:50 ssh to the beagle and start the cloud9 service dammit Jun 06 08:48:56 jeez Jun 06 08:49:01 how to do that in ssh Jun 06 08:49:05 not a clue Jun 06 08:49:10 try reading the manual Jun 06 08:49:21 which manual Jun 06 08:49:28 the cloud9 manual, what else? Jun 06 08:49:33 car repair? Jun 06 08:54:16 I mean, it should be running by default (on port 80 on current images afaik) Jun 06 08:55:07 I suddenly remember why I stopped hanging out in this channel Jun 06 08:55:28 lol Jun 06 08:56:41 I mean, usually you can already tell by the very first line someone speaks whether or not they're going to be frustrating, so you can just choose to ignore them when not feeling in the mood Jun 06 08:57:12 yeah, I admit I was immediately suspicious of this one Jun 06 08:57:26 I noped the hell out of this one at first glance, lol... not in the mood Jun 06 09:00:32 I thought maybe I should do a good deed for once Jun 06 09:00:39 but I guess today is not that day Jun 06 09:05:49 mru: you did your good deed for this year, now you can lean back and observe the show. I just stay here for the occasional interesting problem or when I feel very charitable. Jun 06 09:06:54 sometimes I wonder how these people manage to breathe without someone telling them how Jun 06 09:08:21 personally, I think it's a mistake to ship these boards preloaded with all the bells and whistles Jun 06 09:08:54 it's not a bloody ipad Jun 06 09:11:11 and where's my coffee? Jun 06 12:41:19 Sagar you can do sudo systemctl status cloud9. See if it is active or not. and if inactive can try sudo systemctl start cloud9 Jun 06 12:41:38 deepankarmaithan: he left ages ago Jun 06 12:43:02 hmm but mru should not have responded like he did. Not everybody is as bright as he is. Some people are like me just getting started and community is for everyone Jun 06 12:49:55 when I lose patience with people here I usually just withdraw from the conversation Jun 06 12:51:54 he'll probably be back same time tomorrow with exactly the same question Jun 06 12:52:01 that is how it should be Jun 06 12:58:55 doesn't mean I'm always successful either, sometimes people just irritate me too Jun 06 13:04:11 the ones that annoy me most are those who don't even attempt to try to think Jun 06 13:04:25 and expect to be held by both hands all the way Jun 06 13:04:54 while being utterly unable to articulate even what they're trying to achieve, much less what they've actually done Jun 06 13:09:24 the point where I get really annoyed is when someone has some nondescript problem (e.g. unable to log in) and it takes half an hour to discover that they e.g. just tried to do an apt-get install and got a horde of out-of-space errors during the installation or some shit like that, which they didn't think might be important to mention right from the start Jun 06 13:10:40 "I'm trying to do stuff and it doesn't work, please help" Jun 06 13:11:09 or when you explain something to them, they acknowledge it, don't ask any follow-up questions, but then one or two days later show up again and ask _exactly_ the same question they asked originally Jun 06 13:13:14 like, that goes way beyond mere poor ability in communicating Jun 06 13:18:07 Just curiosity: In the BBB, when SYSBOOT[4:0]=11000b, the boot order is SPI0 MMC0 USB0 UART0, but still it can EMAC boot?? Jun 06 13:20:33 no, for ethernet boot you pull up sysboot0 (P8.45) in addition to pulling down sysboot2 (via P8.43 or using S2 button), so the bootmode becomes 11001 which is { spi, mmc0 (sd), ethernet, uart } Jun 06 13:28:32 or a jumper-wire-free option is to use a tiny program like this: https://pastebin.com/raw/2y6Vj1ZJ .. built as an MLO (using the linker script and Makefile from bbb-asm-demo) and stick that onto an SD card (or eMMC) Jun 06 13:30:17 which just overwrites the control module register from which bootrom obtains sysboot0-5, and then jumps back into bootrom Jun 06 13:30:22 software defined jumpers Jun 06 13:31:50 I could probably also directly jump to the boot method I want, but that would have required a bit of effort while this approach is basically trivial Jun 06 13:54:47 great Jun 06 18:48:50 I know this likely a bad idea, but what glaring problems would there be with installing Raspbian on a BeagleBone? Jun 06 18:50:05 what cpu is raspian built for? Jun 06 18:50:22 I'm not a pi user, but isn't raspbian basically debian except they had to recompile everything to be compatible with the ARMv6 processor on the original pi? Jun 06 18:50:46 if it runs on armv6, that won't be a problem Jun 06 18:50:51 other than generally sucking Jun 06 18:51:00 kernel obviously won't work Jun 06 18:51:22 yeah, but you're better off just using the normal debian armhf packages Jun 06 18:51:23 and neither will anything that assumes things about the hardware Jun 06 18:51:32 like poking specific gpio pins Jun 06 18:51:58 so yeah, the pi-specific parts won't work, and the rest will be slower than the normal debian packages Jun 06 18:52:21 so as suggested, a bad idea Jun 06 18:55:52 Thanks for the info. It makes sense that a lot of particulars would not work Jun 06 18:56:35 I've been trying to load up opencv into my pocket beagle and I've been hitting some major bumps that are directing me to look at alternatives Jun 06 18:59:37 I'm trying to get openvino which requires opencv on the pocket beagle. openvino "requires" that you build opencv rather than use a specific release. What reason would openvino need opencv to be built on the system for? Just in general, would there be some advantage or something that a program like openvino could leverage from the opencv build files? Jun 06 19:01:28 TurkeyKittin: basically, debian has two 32-bit arm ports (ignoring the ancient oabi port): "armel" (arm-linux-gnueabi) which supports old ARM processors (minimum ARMv5T since buster, ARMv4T before that) which doesn't require floating-point hardware, and "armhf" (arm-linux-gnueabihf) which requires ARMv7 and floating-point support Jun 06 19:04:11 rpi users wanted the faster armhf with hardware floating-point support, but the ARMv7 requirement meant that plain debian armhf wouldn't run on the RPi with its ARM1176JZF-S (ARMv6K with security extensions) processor Jun 06 19:04:25 thus they created raspbian Jun 06 19:05:21 Ah I see that makes sense Jun 06 19:07:05 also, running vision stuff on an AM335x-based beaglebone or pocketbeagle sounds painful... Jun 06 19:07:08 :D Jun 06 19:08:25 video is not exactly the AM335x's strong suit, having a fairly slow cpu, not much memory bandwidth, slow usb, and not really any options for connecting fast storage Jun 06 19:12:01 Yeah :( That's what I'm expecting in the end but I really just need it to forward video from place to place... Do you know of some similar SoC options? Jun 06 19:13:25 if you "just need it to forward video from place to place", why would you use a "comprehensive toolkit for quickly developing applications and solutions that emulate human vision" (as the OpenVINO docs say) Jun 06 19:14:43 it also seems to require intel hardware Jun 06 19:16:21 or maybe they're just pushing that Jun 06 19:28:32 TurkeyKittin: and openvino doesn't "need opencv to be built on the system", in fact they ship it with a compiled opencv build Jun 06 19:28:50 (targeted at the rpi) Jun 06 19:29:43 though if you want opencv on the bbb you should probably just install it with apt Jun 06 20:15:45 zmatt: yeah, I'm using openVINO to forward video data to external hardware which processes it. openVINO is the interface to that hardware. With regards to openCV, I have been going off of relatively old (2015-2019) guides so I'm probably a bit misinformed. However, as of June 19, 2020, Intel was suggesting that no OpenCV version was built for ARMv7 platforms, hence why it needed to be built from source. To be Jun 06 20:15:45 honest I hadn't really considered even looking Jun 06 20:16:00 Thank you for the idea :> I'll see how far Iget Jun 06 20:16:37 ~8.5 hours of building opencv on the pocketbeagle with the beagle freezing at 100% is a bit aggravating Jun 06 20:29:56 TurkeyKittin: that's nonsense, both debian and raspbian have opencv packages for armhf Jun 06 20:30:26 lol Jun 06 20:31:29 native-building something as big as opencv on a bbb or pocketbeagle sounds like an act of masochism Jun 06 20:34:14 and how is openvino "the interface to that hardware" ? the openvino ARM package consists of opencv, an "inference engine" that runs neural nets, and examples Jun 06 20:34:35 ohhh Jun 06 20:35:04 ok, I get it Jun 06 20:40:35 I don't know if there's a reason people who've compiled openvino on non-rpi arm devices also compiled opencv from source instead of using existing debian packages Jun 06 20:42:16 does debian still consider cross-compiling impure or unethical? Jun 06 20:42:22 though if it needs opencv 4 then you may need to upgrade from buster to bullseye (if you go that route you may want to consider starting with a console image rather than the iot image. less packages installed means risk of headaches when upgrading) Jun 06 20:42:33 mru: did they ever? Jun 06 20:42:43 maybe not in those exact words Jun 06 20:43:04 but they insisted on building everything natively on each target Jun 06 20:43:06 I think it's mostly just often a headache Jun 06 20:43:36 to the point that they refused to accept packages that were to big to build on the small target machines Jun 06 20:43:46 in the "main" package repo Jun 06 20:43:50 well apparently dpkg-buildpackage supports cross-building nowadays: https://wiki.debian.org/CrossBuildPackagingGuidelines Jun 06 20:44:22 guess they finally came to their senses, or at least a bit closer to them Jun 06 20:46:25 we use distcc to distribute compilation from the bbb to a build server... it has the benefit of greatly reducing compile time without any of the headaches associated with cross-building Jun 06 20:46:42 it does however mean that linking is still done on the bbb Jun 06 20:47:08 these days linking can take a significant chunk of time Jun 06 20:47:23 with LTO and stuff Jun 06 20:47:39 lto still isn't used that often yet I think Jun 06 20:47:41 but yeah Jun 06 20:48:18 firefox uses it, I think Jun 06 20:48:53 I don't anticipate having a desire to run firefox on a bbb any time soon, let alone compile firefox for the bbb :P Jun 06 20:49:06 me neither Jun 06 20:49:16 but apparently there are people who do Jun 06 20:56:35 zmatt: It definitely feels like an act of masochism :) Jun 06 22:01:41 zmatt: also it looks like they only have opencv 3 and not opencv 4 installable through apt or really anywhere that I have found :( Jun 06 22:01:59 So I'm heading for the cross compile route with outdated instructions Jun 07 00:56:37 zmatt: your asm-demo works.. but some of StarterWare examples don't.. I may use those 4 leds as checkpoints... **** ENDING LOGGING AT Sun Jun 07 02:59:56 2020
