**** BEGIN LOGGING AT Mon Feb 09 02:59:58 2015 Feb 09 03:23:55 Nevermind on my question; the issue was with flashrom and the SPI flash chip. Feb 09 03:31:13 hi guys; anybody have any good reading material for writing device drivers on linux? Feb 09 05:47:23 jkridner: sorry, back now... Feb 09 05:55:09 Hi, I want to know is it necessary to install the kernel , dtb and rootfs every time you build a new one or only the kernel is sufficient. Feb 09 06:03:51 if you just rebuild the kernel, there is no need to reinstall rootfs Feb 09 06:04:02 not dtb is you didnt touch anything dtb related Feb 09 06:04:05 nor* Feb 09 06:10:49 means after rebuilding the kernel just i have to load the new kernel only Feb 09 06:12:11 yes Feb 09 06:12:18 why the pm? do you have secrets? Feb 09 06:12:29 nope Feb 09 06:12:39 well then Feb 09 06:13:04 but if it is a diferrent kernel than the kernel in my board . then what ? Feb 09 06:14:52 if it was the same kernel, why would you replace it? Feb 09 06:15:02 suposse my board kernel is 3.8.13-bone20 but i have build a kernel 3.8.13-bone 53 and also 3.18 then can i load these kernel Feb 09 06:17:28 sure Feb 09 06:17:34 kernels can be upgraded Feb 09 06:18:36 without touching the dtb and rootfs Feb 09 06:18:41 ?? Feb 09 06:19:45 yes Feb 09 06:20:01 the whole point about DT is to decouple it from the kernel Feb 09 06:21:35 means?? Feb 09 06:32:06 the whole point of DT is to obsolete the smaller chips Feb 09 06:47:39 Hai all, Is this possible to display image in u-boot for bbb? Feb 09 07:05:26 yup type #iminfo command in your u-boot prompt. Feb 09 07:08:10 bunty: result of iminfo command is "## Checking Image at 80200000 ... Feb 09 07:08:10 Unknown image format!" Feb 09 07:15:24 you'll have to load the image first Feb 09 07:16:14 but iminfo is for showing header information for application image rather than displaying a graphical picture on a display Feb 09 07:17:28 #embed : the o/p should be like this Feb 09 07:17:31 => iminfo ## Checking Image at 00400000 ... Image Name: Linux-2.6.11.6 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 891164 Bytes = 870.3 kB Load Address: 00000000 Entry Point: 00000000 Verifying Checksum ... OK Feb 09 07:18:24 what distro are u using ? Feb 09 07:23:38 bunty: Am using uboot-2013.04, and am porting it for out custom board. i have initailised TFT and also backlight. And i included my image.h file in u-boot/driver/lcd/ driectory and followed this link "http://e2e.ti.com/support/arm/sitara_arm/f/791/p/217383/849350". Feb 09 07:23:38 bunyt : And this is my error " undefined reference to `Lcd_Init' Feb 09 07:23:39 bunty : And this is my error " undefined reference to `Lcd_Init' Feb 09 07:23:41 adj: i have included my image.h file in u-boot/driver/lcd/ Feb 09 07:24:37 bunty : Am using custom build- Yocto - poky Feb 09 09:41:21 where should i put my dtbo files on debian wheezy? i placed them in the default /lib/firmware path but then echo some-overlay > $SLOTS says "failed to load firmware" Feb 09 10:36:30 Anyone got an idea when/if the 3530 'Advisory 1.39: HS USB OTG Software Reset Is Not Fully Functional' was fixed in the kernel? Grepping and gitlogging now, but maybe someone knows? Feb 09 12:32:17 hi, i have installed debian emmc flasher image from elinux Feb 09 12:32:33 now i cant see usbmodem device in /dev Feb 09 12:32:43 how can i install this device Feb 09 13:00:48 jkridner: sorry, I missed you -- you around now? Feb 09 16:17:50 Hello Feb 09 16:19:12 someone help me with uart2 the beagleboneblack ? Feb 09 17:25:30 what is the easiest way to run code on the DSP of a beagleboard-xm, currently attemping using dsp bridge but wondering if there is a better way to just run the code on the dsp Feb 09 17:31:42 HI, How can I make my LCD work with BBB? Feb 09 18:49:36 Is the driver to access the PRU units in the BBB in mainline Linux 3.19? Or is it a module that has to be built separately? Feb 09 18:54:02 ah, found it. uio/uio_pruss.c Feb 09 19:01:26 hi cwshep Feb 09 19:31:18 I am looking for some help with the BBB rev A5B, I am attempting to change mux mode of P9_26 pin to mode 0 = uart rxd. I am testing this via hyperterminal rs232 connecting tx lines of computer to rx of BBB and sending characters. After "successfully" setting mux settings on this pin and cat /dev/ttyO1 all I can get an output for is the up/down/left/right arrows and home and end buttons with an output of "Rr" I have checked my baud set Feb 09 19:31:28 has anyone heard and problems with this Feb 09 19:31:43 btw using debian Feb 09 19:32:51 any help would be greatly appreciated Feb 09 19:35:28 ?? Feb 09 19:35:31 do you have any other pins set or just that one? Feb 09 19:35:49 just that one. just trying basic level trouble shooting Feb 09 19:36:15 I can end up getting to where ttyO1 will show up in /dev, but can not read anything useful Feb 09 19:36:56 at a minimum transmit data and receive data are usually required Feb 09 19:37:56 I have tried setting up both uart1_rx and tx as well and still get nothing... Feb 09 19:39:06 have you tried a loopback test on the bbb Feb 09 19:39:52 ie. hooking tx to corresponding rx in and out of BBB to check echo/cat? Feb 09 19:39:54 I won't ask whether you've tried force-loading the BB-UART cape :) Feb 09 19:40:06 was how I did it before Feb 09 19:40:15 but that was pre-DT Feb 09 19:40:45 ya, I believe DT is what is giving me troubles Feb 09 19:40:56 you could try echo, or just a remote terminal and see if it echoes your input Feb 09 19:41:22 have you turned off all flow control/etc Feb 09 19:42:09 both ends ;) Feb 09 19:42:37 stty -D raw -echo || works well Feb 09 19:42:39 I have tried that, basically my test was wire pin P9_24 to P9_26 and echo in one terminal cat in another and it works fine, so now I am just using hyperterminal with a USB to RS232 and wiring the tx from there is the rx on the BBB and getting nothing Feb 09 19:43:02 you've done the RS232/TTL conversaion I assume ;) Feb 09 19:43:07 yes I have done a lot of different variations of the port settings Feb 09 19:43:09 conversion Feb 09 19:43:39 by conversion what are you referring to? data levels? Feb 09 19:43:44 otherwise your voltage levels will all be wrong Feb 09 19:44:09 TTL serial will idle 'high' ~ 5V or VCc, RS232 should idle at -12V or -Vs Feb 09 19:44:19 iirc Feb 09 19:44:29 also are you using a modem initializer string... those can cause unpredicatbility Feb 09 19:44:35 they are not interchangeable :) Feb 09 19:44:50 that must be what it is... Feb 09 19:45:31 my setup is basically a usb to rs232 tx line wired to BBB P9_26 UART1_Rx Feb 09 19:45:47 so that would cause my problem? Feb 09 19:46:49 yeah the beagle doesn't output rs232 ;) Feb 09 19:47:00 dammit... Feb 09 19:47:00 you need a level translator or bus driver Feb 09 19:47:03 thank you Feb 09 19:47:13 eg. max232 or similar Feb 09 19:47:31 a usb debug lead will also work Feb 09 19:47:38 because they also work at ttl levels Feb 09 19:48:42 ok, will need to look into what we have in facilities Feb 09 19:50:18 thank you for fixing stupid Feb 09 19:50:20 what you can do, is look back on the p9 pins, as mentioned, and you should be able to see what you type out back in Feb 09 19:50:28 eg. with minicom or cat/echo Feb 09 19:50:44 easy mistake :) Feb 09 19:50:57 yes, I have already done this, and it works just fine... Feb 09 19:51:23 well, then you have the mux stuff working :) Feb 09 19:52:01 ok, that makes me feel better, not a huge learning curve with the DT its just logic levels... Feb 09 19:53:03 just did loopback test again, works very easily. thanks again for the help!! Feb 09 19:53:51 and for some random reason .. the rtl wifi card on my a13 board suddenly decided to work. Wtf. Feb 09 19:54:01 -sigh- home time :D Feb 09 21:03:55 hi jkridner Feb 09 21:06:30 jkridner: I've just been trying to touch base with you about the eMMC extractor image, and see if you actually have been able to write 4GB images to any filesystem with it Feb 09 22:48:00 meh. Trying to build a 3.19 for the beagle bone black and the kernel refuses to boot. Nothing after "starting kernel" Feb 09 22:48:24 apparently a watchdog kicks in after some time. Feb 09 22:50:04 can someone provide me with a (lean) .config for a recent vanilla kernel? Feb 10 00:08:41 <_ssl> whats the difference between *.dts and *.dtsi files? Feb 10 00:12:52 Include Feb 10 01:23:13 Ok, managed to build a working 3.19 kernel and am now trying to compile the uio_pruss driver. Feb 10 01:24:23 This depends on CONFIG_ARCH_DAVINCI_DA850 which in turn depends on CONFIG_ARCH_DAVINCI. But when enabling that the kernel fails to boot. Am I missing something? **** BEGIN LOGGING AT Tue Feb 10 01:42:16 2015 Feb 10 01:51:23 is CONFIG_UIO_PRUSS the correct driver for the beaglebone black? Feb 10 01:54:00 Hey folks, just heard about this "BeagleBone Black" device and was wondering if it can be used to create a dedicated USB to IP adapter for connecting a USB Webcam such as the Logitech BCC950 to an IP network and managing it with Security software. All other solutions I have found (in hardware) required a server driver to run in windows to make the hardware work and I really need a standalone self-contained hardware device to do Feb 10 01:55:48 Hey folks, just heard about this "BeagleBone Black" device and was wondering if it can be used to create a dedicated USB to IP adapter for connecting a USB Webcam such as the Logitech BCC950 to an IP network and managing it with Security software. All other solutions I have found (in hardware) required a server driver to run in windows to make the hardware work and I really need a standalone self-contained hardware device to do Feb 10 01:56:15 ircnoob too :) Feb 10 01:56:34 LOL seems the channel is dead tonight... Feb 10 01:58:01 you're likely to run into hardware limitations on the beagle with video .. but you might like to check out the 'motion' project anyway Feb 10 01:59:10 might do -slightly- better off on the pi, because of different hardware and encoding blocks Feb 10 01:59:42 Thanks veremit. Any other solution suggestions then? I really need a standalone hardware device not some hardware software hybrid requiring a computer to run support software... Feb 10 01:59:59 buy an IP cam ;P Feb 10 02:00:19 eg. huacam, trendnet Feb 10 02:00:40 hmmm.... I will look into the PI. I kinda thought that would be overkill due to the dedicated video hardware in the PI whereas I just need ethernet and USB Feb 10 02:00:52 And video. Feb 10 02:01:00 I already have IP cams but wanted to also IP enable my Logitech conference cam Feb 10 02:01:04 you can't just stuff the usb down the ethernet lol Feb 10 02:01:35 obviously, which is why I need a hardware solution Feb 10 02:02:30 Print Servers work as standalone devices so I fail to see what we do not have USB camera IP servers as well Feb 10 02:02:34 you can look at the TI video processors eg. dm365/8 Feb 10 02:02:54 BeagleNoob: standalone print servers use software too. Feb 10 02:03:04 ye there's no nee for a usb/ethernet solutio ... you take the video straight to IP Feb 10 02:03:24 Yes, but Print Servers are self contained and do not need drivers or other software to run on a PC to operate Feb 10 02:03:31 puttong usb 'in the way' is not helpful :) Feb 10 02:03:52 yes I know you've bought a cheap webcam .. its not the same thing lol Feb 10 02:04:38 been round most of these arguments/issues before with customers :) Feb 10 02:04:52 The Logitech BC950 is anything but cheap, look it up.... Feb 10 02:04:55 BeagleNoob: but when you consider using a beaglebone or whatever small computer you'll have to deal with software. Feb 10 02:05:25 sorry, typo, Logitech BCC950 Feb 10 02:06:29 and there is software out there to provide access to a usb camera via network. It is "just" a matter of finding the best solution and setting it up. Feb 10 02:06:31 technically, what you're asking IS possible .. but you're talking about decoding and re-encoding your video stream .. there's no straightforward way I know to 'translate' from usb Feb 10 02:06:50 veremit: there are usb cameras providing jpeg directly. Feb 10 02:07:10 because of the video/bandwidth/processing issues .. you're not going to accomplish it easily with the am335x processor in the beagle .. its not designed for that Feb 10 02:07:14 nomis .. this is true Feb 10 02:07:28 I am running an ExacqVision server and wanted to add this cam to it as well.... The Logitech supposedly encodes H.264 in hardware so maybe that helps Feb 10 02:08:17 Gotcha, thanks guys, very helpful.. Guess no easy solution then... Feb 10 02:08:17 BeagleNoob .. if you're lucky .. you might be able to use something like gstreamer to pull in the stream and forward it to a streaming server eg. live555 Feb 10 02:08:43 but that would be a software solution, correct? Feb 10 02:08:48 yes Feb 10 02:08:53 lots of nasty coding ;) Feb 10 02:09:13 my mate has been tearing his hair out with 3x 1080p HD streams on a core i7 :p Feb 10 02:09:17 UGH, no thanks :-) I guess I will keep the Logitech for web conferences then :-) Feb 10 02:09:33 pick your hardware I say :) Feb 10 02:09:49 +carefully Feb 10 02:10:45 Well, the Logitech was never intended for IP streaming, it was intended for conferencing using a computer and while both MAC and PC compatible without any drivers it does have limitation. Wish it had an IP interface... Feb 10 02:11:30 Thanks guys for the info, at least now I know what I can't do :-) Have a great evening... Feb 10 02:11:52 good luck :D Feb 10 02:12:14 P.S. Have not used IRC in 20 years, I had forgotten it existed :-) All the best! Nite! **** ENDING LOGGING AT Tue Feb 10 02:59:58 2015
