**** BEGIN LOGGING AT Sun Mar 26 03:00:04 2017 Mar 26 07:58:33 hy Mar 26 07:59:57 any one here Mar 26 08:08:23 m_w: do you know if the blue has a 3d accleration? Mar 26 08:20:40 jic23: do you know if the blue has 3d acceleration? Mar 26 08:23:58 It doesn't have a video output.... Mar 26 08:24:21 Chip is same though so in theory could use it.. Mar 26 08:24:45 jic23: can I use it for some kind of image processing? Mar 26 08:24:54 In theory... Mar 26 08:25:00 jic23: hmm.. Mar 26 08:25:14 jic23: what exactly is a 3d accelerator? is it a gpu? Mar 26 08:26:58 Kind of like an early generation GPU. Lots of fixed pipeline. Also i have no idea if there are any docs as it is a powervr part... Mar 26 08:28:09 Hmm binary blob and ti sdk Mar 26 08:28:29 jic23b: I found this https://github.com/patriciogonzalezvivo/thebookofshaders/tree/master/02 Mar 26 08:28:36 from the ideas page Mar 26 08:33:27 First challenge would be firing up the driver. Not sure whether that will even start on recent kernels. Then fiddle around with some open gles2 stuff and see where you get to. Mar 26 08:33:55 Note it isn't going to be anywhere near as quick as a desktop GPU. Mar 26 08:34:05 jic23: yeah.. :D Mar 26 08:34:09 that's for sure. Mar 26 08:43:33 hello everybody :) Mar 26 11:57:06 m_w : Is there a need to put up a video for the project proposal too ? Mar 26 15:22:46 kiran4399: the blue has the same processor at its core as the black Mar 26 15:23:33 http://www.ti.com/product/AM3358 Mar 26 15:23:55 so yes Mar 26 15:24:20 m_w : Could you please review : http://elinux.org/BeagleBoard/GSoC/Serial-Terminal-Server and suggest quotes ? Mar 26 15:24:22 ServerProcessor: I don't think the video is required for the proposal Mar 26 15:24:44 but accepted project did one last year Mar 26 15:24:51 projects Mar 26 15:26:07 Also, I have experimented with device drivers . Is there any further task you suggest I should try on my BBB ? Mar 26 15:27:32 "custom serial device driver" Mar 26 15:27:51 there is already a device driver for the serial ports Mar 26 15:28:01 not sure I would call it custom Mar 26 15:28:21 Oops! I'll change it. Mar 26 15:30:07 ServerProcessor: you explain how the serial port works but what code are you going to write? Mar 26 15:30:58 m_w : Gonna expand that in the timeline. Mar 26 15:31:09 okay Mar 26 15:31:49 Ixon'' enables the port to listen fro xoff and to stop transmitting when it gets an xoff. Mar 26 15:32:12 there are a few typing mistakes on this line Mar 26 15:32:39 Thanks, gonna change that too. Mar 26 15:34:21 "start/stop signal wires" Mar 26 15:34:29 you mean RTS and CTS? Mar 26 15:39:40 Oh I meant when the device is ready to receive data it will assert RTS by putting a +ve voltage on RTS. Mar 26 15:40:52 And then stop sending a signal by putting a -ve voltage when the device is not able to receive any more bytes. Mar 26 15:41:34 Gonna expand that in the proposal right now. Mar 26 15:51:43 phew ...... was a hell of a week ! Mar 26 16:15:10 m_w: I am contemplating on using the gpu for robotic purposes.. Mar 26 16:15:31 m_w: by using some sterio vision processing or something.. Mar 26 16:15:37 m_w: what are your suggestions? Mar 26 16:18:00 not sure if the BBB can handle stereo vision Mar 26 16:18:11 but the gpu can right? Mar 26 16:18:21 if it can it would low resolution Mar 26 16:18:57 the BBB contains a GPU but still might not cut it Mar 26 16:19:39 m_w: if it cannot.. I will leave the concept of sterio vision and use a single cmos camera to be used as an optical flow sensor. Mar 26 16:19:42 https://www.eecis.udel.edu/~zyu/MCP2014/MobileStereoLF.pdf Mar 26 16:20:55 you can try it with the beagleboard x15 maybe Mar 26 16:21:23 but it is a major undertaking Mar 26 16:25:45 m_w: why? optical flow for 320x240 for a single camera at 20hz using gpu is too much? Mar 26 16:33:11 Kiran4399 perhaps look at the dsp on the x15 Mar 26 16:34:44 Can do a fair bit of fast image stuff with those. I did some real time feature tracking on the xm about 7 years ago and the dsp there was definitely fastest option. Mar 26 16:36:28 jic23b m_w: implementing those algos on the x15 is great.. but my question is.. Mar 26 16:36:44 is optical flow for 320x240 for a single camera at 20hz using gpu is too much? Mar 26 16:36:52 *3d accelerator Mar 26 16:41:16 kiran4399: maybe, if you can get it working Mar 26 16:42:44 if you think it will work you might try doing something with the gpu and see how it goes Mar 26 16:43:30 m_w: I think I will load an image and perform some basic operations.. Mar 26 16:43:36 http://derekmolloy.ie/beaglebone/beaglebone-video-capture-and-image-processing-on-embedded-linux-using-opencv/ Mar 26 16:44:22 http://elinux.org/BeagleBoard/GSoC/Ideas#BeagleBone_GPU_offload Mar 26 16:45:00 talk to ds2, he is proposing using the GPU for offloading Mar 26 17:54:51 Hmm i am doubtful there is enough support of GPU to do much of any thing. Agree with m_w, give it a go! Mar 26 18:06:54 trick is getting something working in a reasonable amount of time Mar 26 20:33:53 nerdboy,m_w: hey! there? Mar 26 20:37:32 sure Mar 26 20:38:18 m_w: i was trying to use ums feature of uboot on qemu vm Mar 26 20:38:47 but was unable to find ums in default commands Mar 26 20:39:54 I used latest uboot image under boundry devices github repository Mar 26 20:40:39 which configuration did you use when you compiled it? Mar 26 20:41:05 why boundary u-boot? Mar 26 20:41:17 that's pretty much imx specific Mar 26 20:41:26 mainline u-boot Mar 26 20:42:02 beyond that you need to make sure to add the command support in your configuration Mar 26 20:42:27 nerdboy: I did tried mainline uboot as well Mar 26 20:42:44 m_w:not sure, can you please elaborate Mar 26 20:43:10 it's not in the default config for am335x Mar 26 20:43:20 uka_in: one second Mar 26 20:44:44 apparently you get to patch it Mar 26 20:44:47 nerdboy: oh!! i there any tutorial for this? Mar 26 20:44:58 i am quite new to it Mar 26 20:46:45 there is ./test/py/tests/test_ums.py in u-boot Mar 26 20:47:04 nerdboy: yes! Mar 26 20:47:04 CONFIG_CMD_USB_MASS_STORAGE Mar 26 20:47:27 CONFIG_USB_GADGET_MASS_STORAGE Mar 26 20:47:38 CONFIG_G_DNL_UMS_VENDOR_NUM Mar 26 20:47:44 CONFIG_G_DNL_UMS_PRODUCT_NUM Mar 26 20:47:58 these need to be added to the configuration Mar 26 20:48:17 m_w: ok! Mar 26 20:48:26 google is your friend Mar 26 20:48:53 yeah :-), my best buddy.... Mar 26 20:49:00 the python script says NVIDIA in the comments so at least it works on tegra Mar 26 20:50:03 looks like they may have changed the names in the latest mainline U-Boot Mar 26 20:50:07 black and later all have emmc Mar 26 20:50:29 is it any better in ti-u-boot? Mar 26 20:51:40 i'll try it Mar 26 20:52:17 U-Boot likes to change continuously :) Mar 26 20:56:15 let me ask the U-Boot USB maintainer Mar 26 20:56:39 lot of vendor-y stuff not there yet Mar 26 20:57:15 or still not using dts, etc Mar 26 20:57:34 some boards are kinda stale even Mar 26 20:58:19 * nerdboy add to piece togther missing vendor glue and send a requested readme patch for socfpga Mar 26 20:59:47 http://git.denx.de/?p=u-boot.git;a=blob;f=cmd/Kconfig;h=25e3b783a87fcb51c6ccca4ea547cf5264824b6b;hb=HEAD#l492 Mar 26 21:00:28 http://git.denx.de/?p=u-boot.git;a=blob;f=cmd/usb_mass_storage.c;h=86398fc24e8bf799887d46a60fb4b2b091cba98f;hb=HEAD Mar 26 21:00:50 U-Boot is fun! Mar 26 21:02:30 apparently you might want to disable BLOCK_CACHE for ums Mar 26 21:04:00 nerdboy:is it because ums is only for single bloack devices? Mar 26 21:04:10 *block Mar 26 21:05:16 says "performance" Mar 26 21:05:32 so ums should work better/faster without it Mar 26 21:08:19 https://lists.denx.de/pipermail/u-boot/2016-March/249157.html Mar 26 21:08:39 ^ yeah!! **** ENDING LOGGING AT Mon Mar 27 03:00:02 2017
