**** BEGIN LOGGING AT Tue Mar 14 03:00:03 2017 Mar 14 11:29:04 Hi all Mar 14 11:29:35 I'm interested in one of GSoC idea in http://elinux.org/BeagleBoard/GSoC/Ideas Mar 14 11:29:59 How can I have contact with the listed "Possible Mentors" Mar 14 11:34:07 I want contact with "Michael Welling". However, I cannot find his/her e-mail, nor nickname in this channel Mar 14 11:34:21 Can anyone help me. Thanks in advance Mar 14 11:34:29 clear Mar 14 11:35:20 sorry typing error Mar 14 11:53:38 /msg NickServ VERIFY REGISTER kartikg xizfkpwkedek Mar 14 12:00:12 /msg NickServ VERIFY REGISTER kartikg xizfkpwkedek Mar 14 12:00:33 hi Mar 14 13:24:35 Shankerwangmiao, Michael is m_w. On US time and busy moving house this week. Mar 14 13:25:22 thanks! Mar 14 13:25:56 and sorry I'm new to irc, can I start a new conversion directly to someone? Mar 14 14:04:16 Just mention his tag in a message e.g. m_w how are you, and it will ping him if he is online. Mar 14 14:04:33 Which he isn't yet... Mar 14 15:22:08 Hello everyone Mar 14 15:22:12 I am Rishabh Sheth from India. Mar 14 15:22:27 Currently I am pursuing B.Tech in Electronics and Communication Engineering from Dharmsinh Desai University. I would like to be a part of GSOC'17 with BeagleBoard as student. I am good in C, C++, Assembly language, Linux Kernel Programming plus I have experience in programming of various AVR microcontroller, ARM processor ( NXP's LPC2368 ). I made various project on embedded system and my team was finalist of National Robo Mar 14 15:23:13 I don't used BeagleBoard yet so I am trying hard to get as much as knowledge about it. Mar 14 15:23:16 I am referring Exploring BeagleBone by Derek Molloy , data-sheets and other material available on site. Mar 14 15:23:32 I am interested in project PRUs to offload processing of raw data from on board Peripherals Can anyone suggest me reference or material on this project. Mar 14 15:23:59 Hey rishabh_bb ! Mar 14 15:24:09 Do you have BBB with you ? Mar 14 15:24:24 No Mar 14 15:25:33 Well, I would suggest to see the docs then. Like the PRU manuals and that and try to understand the architecutre .. and how they work. Mar 14 15:26:58 Plus how to get the PRUs working ... and all Mar 14 15:27:34 I mean .. get acquainted with the system and the process even theoritically .. Mar 14 15:27:53 Yes sure, Mar 14 15:28:02 I am doing semester tranning in one embedded company and they have BBB so I will try to get hands on experience Mar 14 15:28:22 Cool ! Mar 14 15:32:36 Thanks for guidance, I have good mentor here at company and he suggested same so I already stared working on this direction ! Mar 14 15:35:13 Again thanks and I will get back to you soon with more updates and my views on how can I implement this project. Mar 14 15:35:13 rishabh_bb: btw I made a few examples here : https://github.com/ZeekHuge/BeagleScope/tree/port_to_4.4.12-ti-r31%2B/examples Mar 14 15:41:28 Ok, I will study this code. Apart from "Hello world" program which thing I should demonstrate to show my ablity to do this project and for batter chance of acceptance? Mar 14 15:43:08 some code up and running on the PRUs and being able to cross-compile the Kernel. Bonus if you are able to boot that kernel. Mar 14 15:43:26 Ok Mar 14 15:43:53 jic23: thanks! Mar 14 15:52:09 zeekhuge: normally at what time are you avalible for chat? Mar 14 15:53:48 Not sure. I am mostly here .... Mar 14 15:53:48 You can mail me if I am not here. Mar 14 15:54:30 Others mentors will also be here and they know much much much more than me .. So you might ask them as well ... Mar 14 15:59:32 Ok , thanks for help. I am leaving now goodbye. Mar 14 16:17:19 jic23: Do you have m_w's email, so that I can send a email to him? Mar 14 16:39:53 How can I enable the PRUSS on the BBB before programming them> Mar 14 16:39:55 ? Mar 14 16:39:57 Thanks! Mar 14 16:58:17 they should be enabled in the default kernels with the pm firmware blobs Mar 14 16:59:30 Is there a test to see if they are enabled? Mar 14 16:59:42 see into your dmseg Mar 14 17:02:24 what ^ he said Mar 14 17:02:46 zeekhuge is an expert now... Mar 14 17:10:02 not even close. Just that, have done some work so know some basic stuff .. Mar 14 17:10:05 :) Mar 14 17:11:09 hi all, how are you zeekhuge? Mar 14 17:11:32 dmesg not once saved my ass Mar 14 17:11:59 Hey pmezydlo ! I am fine :) Mar 14 17:12:02 Is it the PMU? Mar 14 17:13:14 you probably asking about "dmesg" . arent you ? Mar 14 17:13:21 yes Mar 14 17:13:40 just type in "dmesg" in your terminal and that will show the kernel log messages. Mar 14 17:14:39 It is showing a lot of stuff but cannot find PRU anywhere Mar 14 17:14:59 pru-newbie: I have described what it should look like here : https://www.zeekhuge.me/post/ptp_docs_commands_and_tools/ Mar 14 17:15:42 I tried doing a grep on the output with the search term "pru" Mar 14 17:15:59 OK, will have a look. Mar 14 17:16:03 Sorry gonna get up into foobar thing. 3rd level 1st question. so .. later. Mar 14 17:54:41 Hey I looked a bit more into UART and figured out that even if we use 115200 as the baud rate we need 86.8µs to transfer a package. Mar 14 17:55:30 The BBB has a 64 bit FIFO for UART I/O (if I'm not mistaken), which means that we can send up to 6 packages without needing to read the FIFO. Mar 14 17:56:21 This makes 6 times 86.8µs which equals 520.8µs. So we need to read the FIFO at least each 520µs. Mar 14 17:58:01 I talked to zeekhuge about using the PRUs for buffering I/O data received through UART, but as 520µs is a really long time for the A8 we could also rely on a deamon which would read the FIFO and append its content to a buffer. Do you think this would work out well? Mar 14 17:59:45 The great advatage of this attempt would be that the I/O buffer will be able to run on several linux systems which do not have a PRU, like the BB does Mar 14 18:10:47 The main problem I can see is whether we can assume that the daemon which reads the UART FIFO (this could be done by the UART driver) will be scheduled within 500µs Mar 14 21:11:00 hmmmm Mar 14 22:50:10 Some good press for the blue today. Mar 14 22:51:24 All cut and paste news, bit widely covered. Mar 14 22:54:02 this board is awesome Mar 14 22:57:19 Indeed, nice bit of kit. Will be the stuff around it that really matters though. Mar 14 22:59:24 You can see that BeagleBoard community is growing quickly Mar 14 23:05:59 lsnaik: it's okay for other mentors to see it, right? **** ENDING LOGGING AT Wed Mar 15 03:00:02 2017
