**** BEGIN LOGGING AT Fri Oct 19 03:00:00 2018 Oct 19 03:03:17 so I'm now running with it set to 24 bit mode, with 18 pins connected and it looks identical to 16 bit mode. Not sure if it was meant to :) Oct 19 03:34:56 suprothunderbolt: do you have a working configuration for the LCD? Oct 19 05:54:24 CoffeeBreakfast: sorry for the delay, was out to lunch and forgot to look back at this Oct 19 05:54:52 CoffeeBreakfast: yeah I do, it's just the one that ayjay_t posted Oct 19 05:55:58 I haven't got it working perfectly yet. 18 bit looks the same as 16 bit and it's a little off center but it's pretty good :) I'm just compiling the kernel now so I can get the touch screen working Oct 19 07:43:51 fixed the off centre issue, just needed to tune the front and back porch values. Still not sure why they are totally different than the manufacturers example Oct 19 08:13:01 suprothunderbolt: how do you expect 16 and 18 bit to look different? Oct 19 08:53:29 Hi, I have a problem with musb_hdrc driver on BeagleBone Oct 19 08:54:05 I connect a 3D camera through the USB1 port, the Beagle recognizes it, I can connect to it, but when getting data I got a timeout Oct 19 08:54:46 dmesg shows the message: usb 1-1: usbfs: usb_submit_urb returned -121 Oct 19 08:55:10 I'm using Debian 8.3 > > (4.1.15-ti-rt-r43) Oct 19 08:55:17 Any help? Oct 19 08:56:31 jmirats: things you can try: 1. disable usb autosuspend 2. insert a powered usb hub between beaglebone and camera 3. try a newer image Oct 19 08:57:22 I already checked 2 and 3 Oct 19 08:57:27 same errors Oct 19 08:57:41 how do I disable usb autosuspend? Oct 19 09:00:10 you can disable it for a single device using: Oct 19 09:00:25 echo on >/sys/bus/usb/devices/$DEVICE/power/control Oct 19 09:00:48 or for newly plugged-in devices with: Oct 19 09:01:09 echo -1 >/sys/module/usbcore/parameters/autosuspend Oct 19 09:01:47 if it works, you can make the latter persistent by adding usbcore.autosuspend=-1 to your kernel parameters (the "cmdline" variable in /boot/uEnv.txt) Oct 19 09:02:20 ok, let me check that, come back in some minutes. Thanks Oct 19 09:09:33 Hello, I cannot change the contents of /sys/module/usbcore/parameters/autosuspend Oct 19 09:09:40 sudo echo -1 > /sys/module/usbcore/parameters/autosuspend gives me a permission denied Oct 19 09:10:37 and directly editing the file (using sudo vi ...) says "/sys/module/usbcore/parameters/autosuspend" E667: Fsync failed" Oct 19 09:10:38 you can't use sudo like that :) you're redirecting the output of "sudo echo -1" Oct 19 09:11:12 you can do e.g. echo -1 | sudo tee /sys/module/usbcore/parameters/autosuspend Oct 19 09:11:47 yeah I can imagine vi gets confused if you try to use it to edit sysfs attributes Oct 19 09:11:58 ok, now autosuspend is changed Oct 19 09:12:15 let see if it work.... Oct 19 09:12:29 they're not really files, sysfs is a virtual filesystem that represents attributes of kernel objects, and things there don't always behave like a normal filesystem would Oct 19 09:18:00 Now I get a different error bone-pinmux-helper ocp:P8_10_pinmux: could not find pctldev for node /ocp/l4_wkup@44c00000/prcm@200000/clocks/tclkin_ck, deferring probe [ 831.090247] musb-hdrc musb-hdrc.1.auto: VBUS_ERROR in a_host (91, well, sorry those are twol lines of dmesg Oct 19 09:18:25 the deferred probe isn't an error, it's just a remark Oct 19 09:18:34 VBUS_ERROR however is Oct 19 09:18:40 ok Oct 19 09:19:02 and what does this error means? Oct 19 09:20:09 it has to do with the peripheral and/or driver being unhappy with the vbus voltage. I haven't seen it being mentioned in a long long time though since I think it's been fixed ages ago. of course you're using an ancient kernel so it makes sense you're still affected Oct 19 09:21:09 ok. I'll change the kernel again to the newest version for Beagle, being Debian 9.5 and try it again with the option of autosuspend off Oct 19 09:21:22 will take a while... Oct 19 09:21:59 thanks for your help Oct 19 09:22:40 in case I cannot solve it how could I contact you again? Oct 19 09:23:44 I'm usually here, as are other technically capable people. just ask your question and have patience (leave your irc client open) Oct 19 09:24:02 people are in different timezones and often only glance at irc occasionally, so it can take time to get a response Oct 19 09:24:37 ok, normal. Thanks Oct 19 10:03:40 Hi! I m using the CAN communication on the Beaglebone black. I need to upload my application into it but i dont receive all the data from CAN. I guess it is linked to buffer size but I didnt find any way to change it... Does any of you have an idea ? thanks for you help! Oct 19 10:44:16 Hi, I checked with the latest Debian image available, setting sub autosuspend to -1 but it does not work either Oct 19 10:44:34 The error in dmesg is now: usb 1-1: usbfs: usb_submit_urb returned -121 Oct 19 10:48:04 so the same as before Oct 19 11:01:07 a bit of googling yields: "You can ignore that message; it's only there for debugging. It wouldn't appear at all in a kernel built without CONFIG_USB_DEBUG" Oct 19 11:02:07 although it is associated with problems with buggy software Oct 19 11:05:21 what's the *actual* error you're getting? Oct 19 11:06:02 or problem you're experiencing Oct 19 11:06:05 I also googled that and I found it might be related to an error with the musb_hdrc driver Oct 19 11:06:24 link? since I see no indication of that Oct 19 11:07:02 My error is that I do not get data from the camera, I just get an waitForStreams: timeout reached Oct 19 11:07:11 what software? Oct 19 11:07:33 I'm using OpenNI provided by the camera vendor: ORBBEC Oct 19 11:07:47 I wrote an own class wrapping the camera driver Oct 19 11:07:54 and this software works normally on other linux systems? Oct 19 11:07:57 in my desktop PC works perfectl Oct 19 11:08:00 ok Oct 19 11:08:59 in another attempt I got the error: musb_host_rx 1965: Rx interrupt with no errors or packet! Oct 19 11:09:12 that does sound like an musb error Oct 19 11:09:13 and musb_ep_program 916: broken !rx_reinit, ep2 csr 0003 Oct 19 11:10:02 when I googled that, I saw a couple of links talking about a patch to the musb driver, bu I was unable to find that patch. Oct 19 11:10:24 musb used to be a frequent source of headaches... haven't had any problems with it lately myself, but I also don't use usb on the beaglebone that much and certainly don't stress it Oct 19 11:10:29 apart that I do not know how to recompile the musb driver if I found the patch... Oct 19 11:11:26 rebuilding the kernel is pretty easy as long as you have some debian/ubuntu linux system to recompile the kernel (rcn has pretty nice scripts that automate the whole process including building the debian packages) Oct 19 11:12:38 of course if you're reading things that are more than a year old, there's a good chance that such patches have already been integrated (or the musb driver otherwise changed so much that the patch no longer makes sense) Oct 19 11:13:16 the driver has definitely improved over time, and I rarely see reports of usb problems anymore Oct 19 11:15:02 anyway, I need to go Oct 19 11:15:19 I guess is like you mention, however I'm having trouble in getting the images from that camera. Apparently, what it works in my desktop PC with Ubuntu 14.04 should also work in Beagle with Debian 9.5 (now the latest image available); but it is not, and I do not know where to look Oct 19 11:15:52 ok thanks Oct 19 11:33:58 JOIN Oct 19 13:32:24 Hi! I'm looking for some troubleshooting documents for BeagleBoard-x15 REVC. Oct 19 13:34:24 I'm trying to figure out if my board can be saved. I'm using 12V/5A power supply and when pressing the power button nothing hapens. I have been using this board with the same power supply some time now Oct 19 13:44:31 CoffeeBreakfast: did you see my LCD config? apparently it worked for supro. pumped I could actually help someone. It doesn't include backlight control tho. Oct 19 13:45:14 @dead_bbb grab a new image: https://rcn-ee.net/rootfs/bb.org/testing/2018-10-14/stretch-console/bbx15-debian-9.5-console-armhf-2018-10-14-1gb.img.xz flash it with etcher.io and see if it boots.. Oct 19 13:49:47 Hi, trying to read images from a USB camera with BeagleBone, but I have a sub error: Oct 19 13:49:49 [ 591.979321] musb_host_rx 1965: Rx interrupt with no errors or packet! [ 591.985912] musb_host_rx 1965: Rx interrupt with no errors or packet! [ 591.995824] musb_ep_program 916: broken !rx_reinit, ep2 csr 0003 Oct 19 13:50:14 Any help? It seems related to the musb driver itself but I have no idea of where to look Oct 19 14:02:14 rcn-ee[m]: I burned the img you sent to a sd-card with etcher.io. No action, only DC led is on. Any other suggestions? Oct 19 14:11:58 we need to start making youtube videos Oct 19 14:56:31 acutally isnt' that what i'm supposed to do Oct 19 14:56:35 why is reading other people's code so hard Oct 19 14:57:26 all function shsould have a similiar structe 1) sanitize commandline/paramters 2) pull globals 3) pull IPC/ENV inputs 4) busiiness logic 5) factor/prep output for return Oct 19 14:57:59 i don't need variable declerations and string escaping mixed in with matrix operations and structure transformations Oct 19 14:58:11 RD: you asked me to clarify on linkedin what i meant by the "spaces being big" Oct 19 14:58:24 and its because you're listing like 5 different emerging industries as your "interests" Oct 19 14:58:39 i have an "interest" in AR, but so do 5 different companies with >100 people each Oct 19 14:59:00 so i focus my interests on a specific small task or system Oct 19 15:17:39 ayjay_t: this one? -> https://paste.ofcode.org/kSvZGQkcjKaY2qrkXtmUBv Oct 19 15:28:33 yeh Oct 19 15:28:39 that actually has a bunch of different size screens in them Oct 19 15:28:58 you just have to change which one is active Oct 19 15:29:22 (change native-mode=) Oct 19 15:29:33 good Oct 19 15:30:34 * ayjay_t rubs hands together Oct 19 15:30:36 goooooood Oct 19 16:30:15 any thoughts on this: https://octavosystems.com/2018/10/19/the-future-of-sip-providing-a-breadboard-in-a-tiny-package/?utm_source=blog&utm_medium=twitter&utm_campaign=launch&utm_content=1 Oct 19 16:48:43 Sounds promising Oct 19 16:55:51 yeah i'm really interested in it Oct 19 18:04:15 ayjay_t: I see. Thanks for clarifying. Yeah, I am on a path that uses a number of tools. Describing what I am up to does not seem appropriate for this format so I have not spelled out what I am up to. It is not a secret .....just takes a while to describe. Oct 20 01:41:02 Hi Oct 20 01:43:08 Is anyone online ? **** ENDING LOGGING AT Sat Oct 20 03:00:00 2018
