**** BEGIN LOGGING AT Sun Nov 26 03:00:00 2017 Nov 26 03:40:53 Hi. I would like to build Beagle kernel from scratch. Is https://github.com/beagleboard/linux something that I can use? Nov 26 03:54:02 nascentmind: if you just want to apply custom patches and/or customize the kernel config, it's probably easier to use rcn's build scripts Nov 26 03:54:43 https://github.com/RobertCNelson/bb-kernel for his -bone kernel series or https://github.com/RobertCNelson/ti-linux-kernel-dev for his -ti kernel series Nov 26 03:55:05 (in both cases, select appropriate branch for major version and variants like -rt) Nov 26 03:55:58 the beagleboard/linux repository is a snapshot of the patched kernel tree as produced by these scripts Nov 26 03:57:20 zmatt, I would like to contribute to the mainline and would like to know on which tree the development happens. Nov 26 03:59:19 zmatt, if I am not clear I would want to contribute towards mainlining. Nov 26 04:00:17 the repositories I linked to are what rcn uses to maintain his patchsets on top of mainline, although I don't know the specifics of his workflow Nov 26 04:01:01 it contains the patches, and scripts to produce the patched kernel tree, and then build it and create debian packages Nov 26 04:02:31 (it turns each patch into a git commit) Nov 26 04:05:22 zmatt, so he is just committing the patches and patching the mainline, correct? Nov 26 04:06:37 zmatt, patching the mainline means using a script to clone the mainline and checkout the appropriate branch and patch to it. Nov 26 04:08:28 I'm not sure what you're asking that isn't already literally what I said... if you want to know what his scripts do exactly in detail, then I'd suggest studying the scripts Nov 26 04:55:23 zmatt, I will study his scripts. Nov 26 05:19:39 hi all Nov 26 12:18:41 Hi All, I've noticed that with BBB driver there is an FTDI driver, what is this driver for? Nov 26 12:20:54 IIRC that's for the original BBWhite, that has an FTDI chip for added features like JTAG Nov 26 12:22:25 So for BBB i don't need that one, just the other two .INF files? Nov 26 12:32:08 on newer windows you shouldn't need to manually provide any drivers Nov 26 12:32:47 AFAIU those are just for windows 7 by now. Current images have changed to work well across all recent platforms Nov 26 12:35:31 for windows 7 inf files, do i need to sign them if i want to create my "own" driver package. Nov 26 13:33:36 no idea, maybe. That's a windows question, so not really on topic here. Nov 26 18:04:39 Hey guys, i have a BBB wireless, i need to get 4 PWM outputs from board. the question is: " do i need a some shield for this?" Nov 26 18:08:39 Maksym: no, unless you want to connect something that's not electrically compatible Nov 26 18:10:27 the beaglebone's i/o is 3.3v and does not tolerate high current. I think max 4 mA per pin is recommended Nov 26 18:13:21 in general, a "cape" (which is what a "shield" for the BBB is called) is never strictly required, since a cape is just stuff connected to the beaglebone, hence you can also just... connect stuff to the beaglebone ;-) capes may however under certain circumstances be useful to reduce the complexity of your design, if you happen to find a cape that does something you need Nov 26 18:28:58 Im trying to light up my LED with analogWrite with test bonescript at http://beagleboard.org/Support/BoneScript/analogWrite/ Nov 26 18:29:13 but it give already error Nov 26 18:29:21 {"err":"error updating PWM freq and value: undefined, Error: ENOENT: no such file or directory, open 'undefined/duty_cycle'","seq":2} Nov 26 18:29:33 which pins are you trying to use? Nov 26 18:29:52 "P9_14" Nov 26 18:29:53 also, when connecting a led, be sure to use a sufficiently large series resistor Nov 26 18:30:01 ofc Nov 26 18:30:33 hm, that is a pwm-capable pin Nov 26 18:30:41 y Nov 26 18:30:51 which image version are you using? (check /etc/dogtag ) Nov 26 18:31:12 last Nov 26 18:31:17 i have it on my SD card Nov 26 18:33:06 one idea I have is that it might be caused be a subtle incompatibility between the older bootloader on eMMC and the newer OS on SD card... an easy workaround would be to wipe the eMMC (or at least the bootloader there), to ensure the bootloader on SD card will be used instead Nov 26 18:34:08 (reflashing eMMC with the newer image would work too of course) Nov 26 18:37:36 mb... i have read somewhere that this test bonescript at the website are old for newest image Nov 26 18:37:50 assuming the system on eMMC is not too ancient, you can disable the bootloader on it using: sudo dd if=/dev/zero of=/dev/mmcblk1 seek=256 count=1 Nov 26 18:38:01 that's possible too, I never use bonescript and don't know too much about it Nov 26 18:38:18 it seems odd to me though Nov 26 18:39:13 especially since that test script is basically just a call to analogWrite and nothing more Nov 26 18:39:20 and I don't see why its API would have changed Nov 26 18:39:57 but like I said, I don't use bonescript so I can't say for sure :) Nov 26 18:40:25 can u test this bone script on ur BBB for mee? :) Nov 26 18:40:52 I don't have any at hand that has a standard beagleboard.org image installed Nov 26 18:41:14 ah oke np Nov 26 18:44:20 there's also a non-destructive way to confirm whether the bootloader is the issue: power up while holding the S2 button pressed. (it's the button that's neither the power button nor the reset button) you can let go of the button after the power led turns on Nov 26 18:44:35 this causes the bootloader on eMMC to be bypassed Nov 26 18:46:32 i'm making a drone, and i need 4 PWM outputs for my speedcontrollers, i hope i can just connect this pins to my controllers without extra hardware? Nov 26 18:46:40 i have tryed but ... Nov 26 18:47:15 the error you've shown is not related to hardware, it's a software problem Nov 26 18:47:45 y but if i'll fix this problem Nov 26 18:47:53 do i need extra hardware? Nov 26 18:49:10 depends on the speed controller inputs, how much current do they need and are they at a different voltage level? Nov 26 18:49:13 I already answered that. as long as your speed controllers accept a 3.3v pwm signal and don't draw a lot of current from it, then you shouldn't need extra hardware Nov 26 18:53:08 nice, i have a speed controller with 0-3.3 PWM input Nov 26 18:55:16 zmatt are u from NL? Nov 26 18:57:03 why? Nov 26 18:58:02 we can speek Dutch than Nov 26 19:05:33 this channel is english-language, using a different language which most people won't be able to read is rude Nov 26 19:32:20 Oh neat, there are bonescript examples that explicitly target servos, with the right pulse rep rate and everything Nov 26 19:33:11 I hadn't run across that Nov 26 19:45:32 I assume you are going to use an Inertial Measurement System and respond to that from the beagle board by adjusting the speeds of the controllers? Nov 26 19:47:14 yes Nov 26 19:47:36 but ill use MCU6050 Nov 26 19:47:45 3ass gyro Nov 26 19:53:41 You'll have hell sourcing the connectors for it, but you might look into the beaglebone blue for that, it's purpose-built as a robot/flight controller Nov 26 19:54:29 I keep thinking someone's gonna put together a "one of everything" connector pack for the bbblue on Amazon but nobody has Nov 26 19:59:08 Might be something to do on Tindie, especially with such a small market. The pocket beagle just has enough connections for blinking LEDs right? Nov 26 20:02:07 the pocket beagle does something wonderfully right: It puts USB on the headers, so you can make a hub cape. Nov 26 20:03:07 Tindie might be an interesting venue, yeah Nov 26 20:09:35 Hi Nov 26 20:22:44 Maksym: you mean MPU6050? You require an SPI port as well and an program to process the output of the MPU6050. You can do that a number of ways depending on how you write your primary application. Motion control isn't my area of expertise. Nov 26 20:23:35 routing usb2 over a header isn't ideal for signal integrity though, although if it goes directly to a hub chip it probably doesn't matter Nov 26 20:24:34 zmatt: many mainboards do that Nov 26 20:25:16 e.g. front usb on pcs Nov 26 20:25:51 yea I know... I wonder if those actually meet the specs set by the usb consortium Nov 26 20:26:49 myself: Tindie is helpful for getting short run boards connectors etc. For both sides really. USB headers are nice but I was looking at the other stuff maybe I should look at the schematic for it again. It has pads on it for things. Nov 26 20:26:53 That's a good question, I might have occasion to play with a USB2 compliance tester shortly, I'll try to remember to compare front-panel ports against mobo-integrated ports Nov 26 20:27:11 they should with the usb sticker on them.. Nov 26 20:27:35 right, because noone would put an usb logo on non-compliant things of course Nov 26 20:27:39 :) Nov 26 20:28:20 And no one would ever draw more than 500ma from a connector because of the standard either. Nov 26 21:23:44 Anyone has problem connecting BBB to the newest windows 10？ Nov 26 21:24:42 I am sure I have all the correct drivers installed and there is RNDIS device shown in device manager while my BBB is connected but I just cant ssh into 192.168.7.2 nor can I open it in Chrome Nov 26 21:24:52 Please Help! Nov 26 21:30:04 run ipconfig at a command prompt Nov 26 21:30:22 see if you see the rndis interface having an IP address Nov 26 21:30:54 Okay, Thx I will try that now Nov 26 21:39:31 I can see there is an IP address Nov 26 21:39:36 but its not 192.168.7.2 Nov 26 21:40:01 it seems to be 169.254.200.62 Nov 26 21:40:18 and when I try to ssh into it, it requires password which I dont have Nov 26 21:42:57 Any idea whats going on? Nov 26 21:45:39 It would likely be an intranet IP not a normal internet address. Nov 26 21:46:38 yeah, that's not the right interface then Nov 26 21:47:19 the bbb should be offering DHCP on the rndis interface Nov 26 21:47:48 anyway, the .62 is your address, so you're ssh'ing into your own PC. Nov 26 21:51:17 I just got dropped out of the chat Nov 26 21:51:42 May anyone provide any insights? Nov 26 22:01:14 It would likely be an intranet IP not a normal internet address. Nov 26 22:01:15 yeah, that's not the right interface then Nov 26 22:01:15 the bbb should be offering DHCP on the rndis interface Nov 26 22:01:15 anyway, the .62 is your address, so you're ssh'ing into your own PC. Nov 26 22:01:38 myself emitted the last 3 lines Nov 26 22:02:56 Okay, but when I checked the settings of the connection I had, it says DHCP enabled Nov 26 22:06:05 I got this problem since the last bit windows update issued about 3days ago lol Nov 26 22:16:05 windows the virus you pay for Nov 26 22:26:54 hahaha so true Nov 26 22:27:07 Every update is an adventure I never wanted Nov 26 22:27:21 Anyone with any option that I may try? Nov 26 22:28:21 uninstall the rndis device and let it reinstall when you replug the bbb? Nov 26 22:38:37 Tried that several times, not really helping Nov 26 22:39:19 I think there is something wrong with the newest version of windows10 with RNDIS drivers, Or I have no idea why it is not working Nov 27 01:59:05 uhh, no driver installation should be needed on windows 10, it should work out of the box Nov 27 01:59:31 (if the beaglebone is running a sufficiently recent image) **** ENDING LOGGING AT Mon Nov 27 03:00:01 2017
