**** BEGIN LOGGING AT Thu Aug 06 02:59:57 2020 **** BEGIN LOGGING AT Thu Aug 06 04:09:43 2020 Aug 06 04:48:09 Hi Aug 06 04:48:51 Is it possible to install Node-red in BeagleBoard Aug 06 04:49:19 it's installed by default on current IoT images Aug 06 04:49:46 You mean to say it comes with node-red Aug 06 04:50:12 yes Aug 06 04:50:24 Is there any BeagleBoard which has 4g Connectivity using SIM Aug 06 04:50:40 not integrated no Aug 06 04:50:41 My requirement is 4g (SIM) connectivity + Node-red Aug 06 04:51:04 Thanks a lot..If I want how do I need to do that Aug 06 04:52:57 Is there any way I can have 4g SIM in BeagleBoard Aug 06 04:53:16 that's a vague and broad question. beagleboard.org creates a bunch of different boards with different connectivity and expansion options, and modems can be connected in various ways Aug 06 04:53:55 Let me tell my requirement Aug 06 04:54:07 e.g. for the beaglebone black a quick google yielded these: https://www.yantrr.com/m2m-cape-for-beaglebone/ Aug 06 04:54:30 and this one: https://nimbelink.com/products/skywire-beaglebone-black-cape/ Aug 06 04:54:56 Ok... Aug 06 04:56:08 The place where we are going to installing is not having Wifi..So we wanted to have SIM so that we can connect to our gatway for data TX Aug 06 04:56:12 connecting a module via usb might also be an option, though usb on beaglebone black (and other AM335x-based boards) is not great Aug 06 04:57:16 I think you can also buy small modems/routers that have 4g and to which you can connect devices (such as the beaglebone) via ethernet Aug 06 04:58:14 there are no doubt also tons of modules that you could interface to the BBB with a bit more effort (potentially some soldering) Aug 06 04:59:03 e.g. if they have a UART or SDIO interface Aug 06 05:00:53 Ok..I am looking for in built..Do you have any suggestion on this Aug 06 05:02:25 I'm confused by why you are repeating a question already anwered. none of the beagleboard.org boards have integrated 4g/lte (nor do I know of any other arm-based SBCs that do), though I enumerated a whole bunch of easy ways of adding 4g/lte connectivity Aug 06 05:04:25 standalone 4g/lte modems (with ethernet and/or wifi connectivity) seem to be available for reasonably low price Aug 06 05:06:35 (only barely more expensive than usb sticks, so I'd definitely strongly recommend one with ethernet connectivity over a usb stick) Aug 06 10:06:11 Hi. I need a watchdog on PocketBeagle board. The problem is that when I start iperf with lot of threads >1000 the board CPU load is 100%, heartbeat led stops blinking and the ssh connection interrupts. The question is: if the PRU stop blinking Led will any software watchdog help to reboot the board, or I should use hardware watchdog (stm32f1 for Aug 06 10:06:11 example) ? Aug 06 10:58:22 Siegurd: 1. the AM335x has an integrated hardware watchdog 2. cpu load has no effect on PRU, the hearbeat led is done by the kernel and it stopping strongly suggests a kernel panic/lockup 3. aforementioned kernel panic/lockup should be considered a kernel bug **** BEGIN LOGGING AT Thu Aug 06 11:00:15 2020 Aug 06 11:00:30 also, running over 1000 threads does not sound like a very realistic workload for a small embedded system Aug 06 11:03:28 the heartbeat can glitch under very heavy load, but it should never stop entirely Aug 06 11:16:16 and I just tried running iperf with 1000 threads, I just got out-of-memory errors Aug 06 11:19:53 and the remaining threads are connecting to my iperf server at an excruciatingly slow rate (about 2 per second) Aug 06 11:20:31 2 what? Aug 06 11:20:36 bits, packets? Aug 06 11:20:42 or just 2 in general? Aug 06 11:26:34 connections Aug 06 11:28:17 and dunno what it's doing now... it made a bunch of threads and connections and now it's just sitting there are 0% cpu load... I guess the failed thread spawns made it choke (maybe it waits until all threads have established a connection and are ready to transmit before the actual benchmark is done?) Aug 06 11:28:54 no reaction to control-C, had to control-\ it Aug 06 11:29:11 and of course the person asking the question has left Aug 06 11:29:34 why do I even bother testing shit for people Aug 06 11:30:07 "cannot reproduce. issue closed." Aug 06 11:31:07 oh wait Aug 06 11:31:09 pocketbeagle Aug 06 11:31:29 so he was trying to do this via usb networking? lol Aug 06 11:39:31 maybe he also races usain bolt while on crutches Aug 06 11:40:35 they should make a beagle with two gbe ports and call it the packetbeagle Aug 06 11:40:46 lol Aug 06 12:46:10 how about a circular board with a hole in the middle: the bagelbeagle Aug 06 12:46:40 or would it be just baegle? Aug 06 12:49:05 I like baegle. Short. Catchy. **** BEGIN LOGGING AT Thu Aug 06 13:27:57 2020 Aug 06 14:01:56 noice **** BEGIN LOGGING AT Thu Aug 06 15:06:44 2020 **** BEGIN LOGGING AT Thu Aug 06 17:12:45 2020 Aug 06 20:17:34 Latest problem, I'm using libusb to read data from an external device plugged into the front USB via a hub. When I unplug the hub I get what seems to be a kernal panic, then USB is messed up until reboot. Aug 06 20:26:02 https://pastebin.com/uc29GC35 Aug 06 20:30:40 Same thing happens w/o the hub in the mix. Aug 06 20:31:22 However w/o the hub USB is able to recover. I see some odd things in the log, then it works normally. Aug 06 20:32:19 Odd being: "musb-hdrc musb-hdrc.1: Babble" a few times scattered in the usb init entries. Aug 06 20:36:31 Ok. Party messed up. The external device re-initialized. A USB stick doesn't. It keeps saying it has a new device about 1/sec until unplugged, with a power cycle attempt every fourth device logged. Aug 06 21:11:40 Without the hub it does that once, the first time is unplugged. After that the error isn't logged again until reboot, but the Babble messages appear for a variable amount of time when anything is plugged in, where normally they do not. **** BEGIN LOGGING AT Thu Aug 06 22:42:42 2020 **** BEGIN LOGGING AT Thu Aug 06 23:34:16 2020 Aug 07 01:08:26 hey to boot off the SD if you flashed the eMMC before do I need to do anything special? Aug 07 01:08:31 this is on the black Aug 07 01:34:00 # it! Aug 07 01:41:40 MattB00ne: Do you mean that you have a eMMC image on the board and you just plug in another SD Card with a different image? Aug 07 01:42:29 Hold down the S2 button or update the eMMC. Aug 07 01:50:06 Or... Aug 07 01:50:40 There is a section of the /boot/uEnv.txt file you can '#' to comment "that" line that turns the image into an eMMC image. Aug 07 01:59:08 # it to turn it into a SD Card image && de-# it to turn it into a eMMC image. Aug 07 01:59:10 Sorry. Aug 07 01:59:27 Does that help? Aug 07 02:32:32 ummm Aug 07 02:32:52 confused Aug 07 02:33:03 so I need to edit my uEnv.txt to boot from sd Aug 07 02:36:56 No or you could. Aug 07 02:37:42 I would say if you do not know how to change the # to no # and back, use the S2 button when booting into your SD Card. Aug 07 02:38:19 I am learning about bs4 again. The tutorials are getting me angry. I have to move on from bs4. Aug 07 02:38:21 For now! Aug 07 02:46:17 MattB00ne: if you'll be booting from sd card from here then it's recommended to wipe eMMC assuming you no longer care about its contents Aug 07 02:47:02 this mainly to ensure it'll use u-boot from SD card rather than from eMMC Aug 07 02:49:31 MattB00ne: you can ignore everything set_ said, as usual **** ENDING LOGGING AT Fri Aug 07 02:59:57 2020
