**** BEGIN LOGGING AT Sun Dec 03 03:00:01 2017 Dec 03 11:08:50 Hi! Dec 03 11:09:21 Any activity here? Dec 03 11:34:59 Good morning, I installed kernel 4.4 on beagleboard black and SGX drivers. I understand the graphic is 3D accelerated for OpenGL and tried it. Dec 03 11:34:59 Is there a 2D acceleration, I tried SFML 2D drawings and it's running quite slow. Also wondering if the default beagle board black installation has any hardware graphic acceleration or graphic drivers have to be installed. Dec 03 11:37:41 I don't think any of the official images have the drivers installed Dec 03 11:40:11 apparently the SGX530 has 2D acceleration Dec 03 11:40:38 there probably is some sort of script to install the drivers though Dec 03 11:40:59 also for your own purposes you can then turn that into a flashable image, again using a script in /opt Dec 03 11:54:44 jfsimon1981, for 3d I had to make a Yocto image myself, because official TI drivers work only with Wayland and there's no othe distribution that allows to be as flexible with graphics setup Dec 03 11:55:06 *other Dec 03 11:55:31 I'll have to figure out how to use the 2D acceleration. It must be OpenGL. Dec 03 11:56:07 AFAIK, same thing here, SGX drivers are only compatible with Wayland these days Dec 03 11:57:13 I successfully installed SFML with ES Dec 03 11:57:57 But I guess the normal draw does'nt use the 2D acceleration. Dec 03 11:58:14 i mean sfml'd standard draw. Dec 03 11:58:59 OpenGL 2D must be it. Dec 03 12:00:30 it doesn't matter if it is 2D or 3D, if there isn't official TI's drivers beneath. Have a look: http://git.ti.com/gitweb/?p=graphics/omap5-sgx-ddk-um-linux.git;a=blob_plain;f=README;hb=refs/heads/ti-img-sgx/1.14.3699939 Dec 03 12:19:41 you can use it directly from Qt too AFAIU Dec 03 12:28:02 Tx Dec 03 12:43:22 it is possible to get the drivers working on debian as well, with some effort Dec 03 12:43:31 haven't tried wayland yet though Dec 03 12:50:00 never tried myself, but I think I saw a script in the image Dec 03 12:50:41 iirc rcn even built packages for some kernel releases Dec 03 12:56:12 I think I updated the kernel, build and installed the SGX driver in debian. It's 4.4 kernel with SGX drivers and seems working well. The 3D cube example runs smooth on a higher resolution HDMI screen. I'm trying to understand the 2D stuff because I would like to drawing flight instrument panel for x-plane. Dec 03 12:58:25 I *guess* you'd need one that can be run in a compatible way, like openGL or with the right Qt backend Dec 03 13:00:06 I installed ES SFML that's compiled with OpenGL for embedded system. Their X11.cpp example works and seems weels accelerated. It's at about 20+ fps on 1400x800 Dec 03 13:00:17 still experimenting Dec 03 13:00:30 *nod* good luck with your endeavour :) Dec 03 13:01:07 So small BBB running so smooth on modern hdmi really beautiful. Dec 03 16:11:59 Is there a way to get bluetooth on beaglecore? Dec 03 16:37:06 connect a bluetooth chipset (e.g. via usb or uart) Dec 03 18:55:15 How many I2S ports are directly available on BBBW P8 and P9 connector? What is pinout for I2S ports? Dec 03 19:02:56 looks like one i2s port. I googled "beaglebone i2s" and opened a few links. Dec 03 19:03:03 "it depends" Dec 03 19:03:12 this: https://hifiduino.wordpress.com/2014/03/10/beaglebone-black-for-audio/ Dec 03 19:03:18 led me to this: https://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/07/06/bbb--building-a-dac Dec 03 19:03:26 which links to this: https://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/05/28/bbb--audio-notes Dec 03 19:03:31 which has the pinout ^^ Dec 03 19:04:18 there are two mcasp peripherals, though mcasp1 has rather limited pinout Dec 03 19:05:14 one mcasp peripheral can however connect to multiple codecs, but there can only be one clock master for the whole group (either mcasp or one of the codecs) Dec 03 19:06:16 (actually, mcasp supports having different clocks for rx and tx, but this isn't well-supported by the mcasp driver... I had to hack in support for it myself) Dec 03 19:07:23 here are some notes I once wrote on the subject: https://pastebin.com/raw/5dhvjDgz Dec 03 19:08:23 keep in mind not all configurations described in those notes are currently supported by the linux mcasp driver Dec 03 19:38:55 Thanks Dec 03 19:39:20 Looks like we can use both McASP ports for I2S. Dec 03 19:39:50 McASP0 available on both P8 and P9 Dec 03 19:40:19 McASP1 available on P9 header Dec 03 19:42:11 keep mind that if you want to use the beaglebone's on-board audio oscillator, you cannot use the 'data 1' signal of mcasp1 since it resides on the same pin (P9.25) Dec 03 19:42:20 this may or may not matter for you Dec 03 19:43:00 i need to use only 1 data pin per I2S port Dec 03 19:43:44 then you use use both mcasp0 and mcasp1, even both on p9 Dec 03 19:44:06 yup understood. Thanks!! Dec 03 19:44:18 (note that the p8 ioset of mcasp0 conflicts with video output) Dec 03 19:45:40 Yes. I looked into this. **** ENDING LOGGING AT Mon Dec 04 03:00:01 2017
