Feb 28 09:09:39 <kiran4399> Is jason kridner there ???
Feb 28 09:16:23 <karki> jkridner seems to be here
Feb 28 11:14:53 <geekswine> hii..i have doubt regarding booting process of wiring framework which is to be implemented in the project similar to energia..
Feb 28 11:15:16 <geekswine> let we call it as BlackArduino..
Feb 28 11:16:27 <geekswine> for starterware... which is for AM335x we have MLO file which will boot using u-boot
Feb 28 11:18:15 <geekswine> i want to compare the process flow of energia and blackarduino which we want to make..
Feb 28 11:19:35 <geekswine> C code in energia -> performs some process -> avr-gcc compiler ->all obj are linked -> send to boot..
Feb 28 11:21:30 <geekswine> so in energia.. on top we have energia environment and on backhand uses arduino framework to upload to board...
Feb 28 11:23:07 <geekswine> so similarly in blackardino, on top we have blackarduino environment and then starterware is used in backhand to compile....but how this blackarduino will be booted up initially when connected to desktop ??
Feb 28 11:23:56 <geekswine> any help plss ???
Feb 28 11:27:03 <geekswine> or it will be otherway round ?? starterware is booted first and then arduino framework is applied ...
Feb 28 11:27:20 <geekswine> am i thinking in right  direction ??
Feb 28 11:32:07 <geekswine> av500: jkridner ??
Feb 28 11:32:10 <kiran4399> hi kridner !! I need to talk to you about some contributions I want to make to one of your project...
Feb 28 11:44:20 <anujdeshpande> jkridner: you around ?
Feb 28 14:04:05 <Guest47105> Hello everyone ,
Feb 28 14:06:52 <Guest47105> I went through the idea and want to PRU bridge or PRUSS support project
Feb 28 14:08:00 <karki> alexanderhiam : thanks a ton for the images :D
Feb 28 14:09:44 <Guest47105> but I don't have much knowledge and experience of working with them , can anyone guide me how to start ?
Feb 28 16:55:57 <altairpearl> hey guys
Feb 28 16:56:36 <altairpearl> i have so far successfully compiled the vanilla kerne v3.18.7l with and without preempt option
Feb 28 16:56:54 <altairpearl> any suggestions before i go on to preempt_rt patch and xenomai?
Feb 28 16:57:09 <altairpearl> v3.18.7*
Feb 28 17:16:37 <alexanderhiam> karki: more captures coming your way
Feb 28 17:16:45 <karki> :)
Feb 28 17:17:11 <alexanderhiam> ~3.8% jitter on the PWM outputs at 2kHz
Feb 28 17:17:57 <karki> alexanderhiam : I was writing a few slides on PyBBIO for my Talk; I'll be done by tomorrow :) care to review it?
Feb 28 17:18:06 <alexanderhiam> cool, sure
Feb 28 17:18:30 <karki> I wonder how that jitter is getting there?
Feb 28 17:18:49 <alexanderhiam> non real-time event loop
Feb 28 17:19:12 <karki> nope, it is; or so I thought
Feb 28 17:19:28 <alexanderhiam> ah, I guess I haven't looked at the pru1 firmware
Feb 28 17:19:38 <karki> it's timer based
Feb 28 17:19:53 <karki> no way I expected it to have much jitter
Feb 28 17:20:16 * karki needs to buy a oscilloscope :(
Feb 28 17:22:32 <alexanderhiam> well if it's based on the pru's timer then it's probably a result of the event loop and timer not being in sync
Feb 28 17:24:31 <karki> alexanderhiam : all it could go wrong is the timing being 10-15ns off
Feb 28 17:24:54 <karki> https://github.com/deepakkarki/pruspeak/blob/master/src/pru-firmware/pru1_firmware.c
Feb 28 17:25:43 <karki> alexanderhiam : I made sure timer does not go off before this line : https://github.com/deepakkarki/pruspeak/blob/master/src/pru-firmware/pru1_firmware.c#L99
Feb 28 17:27:43 <karki> oh wait...... yeah I expect approx 3 inst here there
Feb 28 17:27:51 <karki> thats 15 ns approx
Feb 28 17:28:06 <karki> which comes down to 3.8% :(
Feb 28 17:28:33 <karki> I should probably compile with the -o3 flag and check!
Feb 28 17:47:58 <alexanderhiam> hey jkridner, you had a chance to take a look at that unit test cape?
Feb 28 17:48:32 <alexanderhiam> karki: this might be of interest to you as well: https://github.com/graycatlabs/UTCape
Feb 28 19:06:13 <geekswine> hii..i have doubt in booting process of starterware project..
Feb 28 19:06:22 <geekswine> likewise in energia in front end there is energia environment and on back hand arduino environment works. So process flows from energia to arduino and then .hex file is uploaded.
Feb 28 19:06:39 <geekswine> in this project starterware will be in backhand and some environment will work front end. So while booting BBB, with which MLO file it will boot ?? starterware's ??
Feb 28 19:18:27 <geekswine> anybody ??
Feb 28 19:54:13 <geekswine> jkridner: av500 anything ??
Feb 28 20:23:42 <_av500_> geekswine: sorry, its weekend
Feb 28 20:24:23 <geekswine> ohh...okk..sry..
Feb 28 20:24:37 <geekswine> i'll do some research work..:)
Feb 28 23:07:59 <azizulhakim> If a USB device has more than one interface, it calls the probe function multiple times. We can filter that out using USB_DEVICE_AND_INTERFACE_INFO. But is there any way to know which interface we are interested in as we don't want to send data to ADB interface.
