**** BEGIN LOGGING AT Wed May 27 02:59:59 2015 May 27 03:00:10 heh the am335x is much more versatile imo May 27 03:02:12 * zmatt uploads more powerdown-images to the wiki May 27 04:22:27 hey guys May 27 04:23:49 I am trying to install the xenomai kernel with apt-get install inux-image-3.8.13-xenomai-r72 May 27 04:23:59 which runs fine and after reboot May 27 04:24:13 i still get uname -r May 27 04:24:24 Linux beaglebone 3.8.13-bone71 #1 SMP Tue Mar 17 18:07:44 UTC 2015 armv7l GNU/Linux May 27 04:24:46 ideas? May 27 04:56:16 anyone? I have the standard kernel and xenomai kernal images on my BBB how do i setup to boot xenomai? May 27 04:57:11 make sure your bootloader is actually using the new kernel? May 27 05:13:04 yeah, take a look at where the xenomai image is on the filesystem, and look at the uEnv.txt to make sure it agrees May 27 05:27:28 is the kernel specified in the uEnv.txt file? May 27 05:28:06 or is it simply copied/written to the appropriate place on disk/etc May 27 06:45:39 Is there an prebuilt image out there with lcd-cape and hardware opengl support? May 27 06:53:39 AFAIU the debian images have provisions for the binary driver and for some of the capes. some assembly required. May 27 07:56:49 Hi. In a setup where a shitty router is placed before a linux PC, is there a way to detect packet drops that happened on the router from the PC? Maybe the IP stack gives this info in /proc? Or some userspace tool akin to tcpdump counts the sequence numbers of TCP sessions? May 27 08:00:28 wireshark? May 27 08:35:36 av500: and how would I automate that ? May 27 08:36:26 I could write something that sounts TCP sequence numbers but surely someone did this before? May 27 08:41:31 ifconfig shows dropped packets on linux, surely ipconfig does on windows too? May 27 08:44:10 i'm on Linux, but I want to check for packets dropped by the router, not the interface May 27 08:44:47 ah May 27 09:23:57 brackets_: wireshark or tcpdump or friends May 27 10:36:12 Hey guys, I have a problem, I want to use the P9 headder, pins 26-31 for PRU May 27 10:36:33 but they are already allocated, not sure to what, can some one please help? Thanks :) May 27 10:37:47 Hey guys, I have a problem, I want to use the P9 headder, pins 26-31 for PRU May 27 11:31:19 exit May 27 14:10:32 BBB Rev A5A connected via HDMI (taking power from USB connection to Dell XPS 8300), How do I get to a command line prompt? I am new to this. May 27 14:12:45 depends on what you are running on the board May 27 14:15:23 Angstrom May 27 14:16:03 CTDeveloper: CTRL-Alt-T May 27 14:16:21 it should also expose a console on USB May 27 14:19:08 I am on IRC via the USB port connected to my Dell XPS 8300 Desktop PC. Should I exit IRC and then do a CTRL - Alt - T ? May 27 14:19:45 oh, console only, no window manager? May 27 14:20:37 it sounds like you're already in a terminal May 27 14:21:22 I also have a HDMI cable attached to my second monitor which shows a menu at the top (Applications, Places, System, and a globe). I am using two different keyboards and mice. May 27 14:22:51 using the kbd that's attached to the beagle, do ctrl-alt-T May 27 14:23:24 My book "Getting started with BeagleBone by Matt Richardson" says to click on a lower left menu and select Accessories -> LXTerminal, but I do not see this choice. May 27 14:28:20 I did a "CTRL-Alt-T" on the keyboard that is attached to the normal USB connector. Nothing happens (I feel like Curly). May 27 14:31:59 CTDeveloper: I can't remember the Angstrom UI, tbh, it's been a long time since i used it May 27 14:32:27 CTDeveloper: but I'd presume that somewhere in the application launchers there's a Terminal launcher May 27 14:33:41 CTDeveloper: you could always do CTRL-Alt-F1, login there and install LXTerminal May 27 14:34:10 Under Applications menu, I have System tools and then Terminal. This shows a prompt "sh-4.2#". May 27 14:34:22 CTDeveloper: bingo! May 27 14:35:06 I will try playing with that. Thank you for your help wmat. May 27 14:56:51 can someone provide me a good reason for choosing linux rather than windows ce May 27 15:00:47 support May 27 15:02:38 vast resources that are available May 27 16:13:36 Q, N. I w May 27 17:19:02 Hi May 27 17:21:04 Has anyone calculate the timelife of EMCC? I have information of BlockWriten/s in my system. May 27 17:21:32 Write and Read captured in 1 day May 27 17:22:15 Hi May 27 17:22:21 Wanted estimate based on the Write / Read, and in the EMMC block information which would be useful her life (hours, days or years) May 27 17:23:10 I am trying to integrate some drivers with the BeagleBone Black , and looking for some pointers May 27 17:23:25 Kernel version 3.14.37 - ti - r57 May 27 17:23:28 CleitonBueno: I'd expect the datasheet for the emmc to have such details. May 27 17:23:44 CleitonBueno, https://www.micron.com/~/media/documents/products/technical-note/emmc/tnfc32_device_health_report.pdf May 27 17:24:07 The device tree system doesn't seem to be well documented, or i don't understand it well enough May 27 17:24:35 I have gone through most of the links I found, but can't for the life of me get an SPI based touch device to work May 27 17:24:43 Can somebody please help ? May 27 17:25:20 ankitdaf, which device? does it have mainline support? May 27 17:26:04 I have an xpt2046 based touchscreen, it is ads7846 compatible May 27 17:26:45 i have spidev1.0 and spidev1.1 showing up, and i managed to compile the ads7846_device module and did a modprobe May 27 17:27:08 spi connections are to 17,18,21,22 on the BBB May 27 17:27:29 ankitdaf, spidev? ads7846 has a proper dt binding: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/input/ads7846.txt May 27 17:28:06 Nice. Thanks rcn-ee. May 27 17:28:18 ankitdaf, you might have to cherry pick dt support fro v4.1.x to v3.14.x.. but it's better then hacking thru spidev.. May 27 17:28:49 rcn-ee yes, i figured, spent the last three days on this :| May 27 17:29:37 rcn-ee sorry for the noob question, but could you possibly outline what broad steps i'll need to take ? May 27 17:30:05 it's hard to find documentation that doesn't include cape manager May 27 17:30:51 honestly, since you have to cherry pick anyways, i'd first ignore 3.14.x and just use 4.1-rc5 (which has capemgr)... May 27 17:31:24 rcn-ee so capemgr is not going to be abandoned ? May 27 17:31:45 ankitdaf, it never was... just got stuck in re-write hell for mainline... May 27 17:32:09 rcn-ee: There is something I can use in the case of SD-CARD, Compact Flash. Analyzing the provided datasheet and use in Linux System? May 27 17:32:20 oh ok.. will update to 4.1-rc5 then May 27 17:32:49 ankitdaf, start with upgradeing to linux-image-4.1.0-rc5-bone3 thru apt... then follow: https://github.com/beagleboard/bb.org-overlays May 27 17:33:01 sorry there's no spi example yet... May 27 17:33:59 rcn-ee ok ! yes, at one point i was so lost, i wanted to go back and check if SPI was even working, but not much reference for that :/ May 27 17:34:49 if you had something working in v3.8.x most of the time, the gpio # is just off by one in v3.14.x/4.1.x.. May 27 17:35:20 hmm yes i read that somewhere May 27 17:35:48 relatively new to this platform, just integrated two uarts, wasn't sure where to look May 27 17:36:22 that is a lot of help May 27 17:36:37 i am going to try this and drop back in in a little while May 27 17:36:47 thanks a lot, rcn-ee ! May 27 17:37:53 rcn-ee: do you have any ideas how to fix builds.beagleboard.org? May 27 17:38:20 ankitdaf, no problem, when you get something work, just ping us and we can add that overlay for users to see as an example.. May 27 17:38:32 jkridner, is the x15 still timing out with buildbot? May 27 17:38:42 yes, it is still timing out. May 27 17:39:15 is there any permissions noise in the journel? May 27 17:41:20 nope, not on either side. May 27 17:43:38 I'm still not sure why -v in the environment variable doesn't seem to be generating any verbose traffic on the compression. May 27 17:43:46 stderr should be recorded May 27 18:18:01 http://beagleboard.org/blog/2015-05-27-BeagleBone-Black-and-Android-Combine-in-Super-Cape-Attachment/ May 27 18:57:09 I have random issues between 2 BBBs over rs485 with BeagleBone Serial Cap using UART4. Doing cat on /dev/ttyO4, I receive with delay characters while omap_serial receive it instantly according to added traces. Someone saw similar issues ? I see that TI wants to switch from omap-serial to 8250-core. Would it be a solution ? (I am on kernel 3.12.10 - tty parameters : 115200 cs8) Thanks May 28 00:56:34 grr.... doesn't seem to matter what I 'echo XXX 0x19|0x1e > new_device', I never seem to get any useful driver probing for my LSM303 accel/mag. :( May 28 00:56:45 * jkridner wonders who knows the magic incantation. May 28 00:56:59 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/iio/magnetometer/hid-sensor-magn-3d.c isn't revealing anything magical. May 28 00:57:20 is that a bare LSM303? May 28 00:57:36 or you have a sensorhub/controller in front of it? May 28 00:57:49 ds2: bare, as far as I know. May 28 00:57:52 ah May 28 00:57:54 wrong driver May 28 00:57:55 'i2cdump -y -r 2-8 1 0x1e' works fine. May 28 00:58:02 oh? May 28 00:58:16 that driver is for a HID/I2C or HID/USB hub with the mag May 28 00:58:29 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/iio/magnetometer/st_magn_i2c.c doesn't work? May 28 00:58:49 grr. May 28 00:59:09 that might May 28 00:59:18 which LSM303 is this? May 28 00:59:29 the suffix matters :( May 28 00:59:30 I am confused why 'echo lsm303dlhc-magn 0x1e > new_device' wasn't giving errors. May 28 00:59:49 LSM303DLHCTR May 28 01:00:11 cuz that's not what that driver provides :D May 28 01:00:26 thought it should have returned some error. May 28 01:00:38 ok so this is the "newer" one with the single I2C bus (vs the DLC which had 2 buses) May 28 01:00:53 nope. I think what it does is remember that you have such a device so when a module gets loaded, it will be attached May 28 01:01:06 i have drivers for that chip but mine doesn't use IIO May 28 01:01:40 I am just looking for something that works that can be put in http://github.com/beagleboard/linux. May 28 01:01:50 better if upstream. May 28 01:01:52 do you mind if it uses input events? May 28 01:02:04 wanted to avoid using i2c-dev, but perhaps I could just use that. May 28 01:02:26 I have that chip on my board May 28 01:02:28 ds2: how do you refresh the input events? what are the triggers for the events? May 28 01:02:39 jkridner: hmmm? you just use evtest on it May 28 01:02:59 i know how to read it, I'm just wondering how you tune the frequency of events. May 28 01:03:08 evtest will wait until the event occurs. May 28 01:03:26 yes, you set that through sysfs if the driver supports it May 28 01:04:41 don't have that rev of hte board plugged in so I can't show you an ls May 28 01:04:54 I just think it isn't the best experience to just have userspace drivers for these things. May 28 01:05:02 but for example - the HMC5883: May 28 01:05:23 /sys/bus/i2c/drivers/hmc5843/3-001e has hte knobs to config the chip May 28 01:06:30 the IIO support for sensors is relatively "new" so finding drivers for them can get tricky May 28 01:06:55 but alas, that fact falls on deaf ears for upstreaming purposes May 28 01:08:46 pull request to http://github.com/beagleboard/linux ? May 28 01:09:20 sure.. give me a day or so May 28 01:09:34 k May 28 01:09:38 you need both the mag and acc drivers for that chip I assume? May 28 01:09:47 yeah... May 28 01:09:52 any other inertial sensors? May 28 01:09:53 I have an LSM330 on this board too. May 28 01:10:05 gyro/mag? or gyro/acc? May 28 01:10:07 I'm trying to prep software for http://bear24rw.blogspot.com/2013/07/beaglebone-gamingcape.html May 28 01:10:41 I see May 28 01:11:06 isn't the LSM303DLHC NRND? May 28 01:36:36 ds2: https://github.com/vogelchr/rpi_gyro/blob/master/lsm330dlc.c ? May 28 01:36:39 NRND? May 28 01:36:45 non-returnable? May 28 01:36:47 ? May 28 01:36:59 ah. May 28 01:37:10 not recommended for new designs. May 28 01:37:12 not sure. May 28 01:53:01 jkridner: there should be more to it then that in that in the driver May 28 01:53:14 it is just the generic transport. that code doesn't expose the data at all May 28 01:54:33 jkridner: try to see if this works in your flavor - http://www.st.com/web/en/catalog/tools/PF258119 May 28 01:54:38 and yes, it is NRND May 28 01:56:58 for that purpose, the HMC5883 + something like the bma150 might be easier to deal with May 28 01:57:11 both drivers in some form should be upstreamed **** ENDING LOGGING AT Thu May 28 02:59:58 2015
