**** BEGIN LOGGING AT Thu Feb 19 02:59:58 2015 Feb 19 05:51:41 Cross compilation normal C code using arm-linux-gnueabi-gcc under Ubuntu 13.10 and then run in beaglebone is working for me. But though cross compilation works for module, the module can't be loaded in beaglebone, says "invalid module format", any suggestion? Feb 19 07:17:46 I was trying to setup qemu for Beagleboard in Ubuntu. So I am following this tutorial:https://wiki.linaro.org/Resources/HowTo/Qemu-beagleboard. When I try to run image from command :"qemu-system-arm -M beaglexm -drive if=sd,cache=writeback,file=./beagle.img -clock unix -serial stdio -device usb-kbd -device usb-mouse -usb -device usb-net,netdev=mynet -netdev Feb 19 07:17:46 user,id=mynet".I am getting following error : "qemu-system-arm: -M beagle:Unsupported machine type.Use -machine help to list supported machines!".Please help in fixing this error. Feb 19 15:59:23 How can i get the mentor convinced that i can handle that project ? Feb 19 15:59:50 do you have a mentor? Feb 19 16:00:29 The mentors will be announced after 20th . right ? Feb 19 16:00:45 No, actually, i was just asking ! Feb 19 16:00:51 we will know if we have been chosen Feb 19 16:01:00 then we need to see how many slots we get Feb 19 16:01:05 then students can apply Feb 19 16:01:19 the best thing you can do is to get familiar with the BBB Feb 19 16:01:23 (and linux in general) Feb 19 16:02:45 Can i post links to my work over BBB ? Feb 19 16:03:04 Can i post them on mailing list ? Feb 19 16:06:06 I would include that in your application Feb 19 16:11:17 OK ! Thank you ! Feb 19 18:02:40 are we allowed to get suggestion on a preliminary solution we r thinking to a project so that we can refine our approach? Feb 19 18:16:11 rubel: You're more than welcome to do so Feb 19 18:22:23 Thanks. For the sound part of "Android Remore Display Project" I was assuming we've to build a driver based on ALSA. But after some research it seems pretty complex and I got the idea that I might be over thinking here. So I just wanted to have some guideline if that's possible Feb 19 18:23:29 contact av500 or vvu Feb 19 18:40:50 @vvu @av500: ping when you get time Feb 19 19:52:01 hi guys, i'm looking for an open source project to contribute. Feb 19 19:53:43 Does someone know a good one involving c/c++, python, or js ? Feb 19 19:53:54 Kernel? Feb 19 21:08:04 ?? Feb 19 21:32:51 rubel: ping Feb 19 21:44:55 hi vvu, I just needed some suggestion on my approach. Feb 19 21:46:19 shoot Feb 19 21:46:42 warning: not an expert in audio drivers, usb ones have some xp Feb 19 21:46:43 For sound part on "Android Remote Desktop" project, I was thinking may be a driver need to be implemented on top of ALSA which seems a complex approach to me. So I am not sure if I am over thinking my approach Feb 19 21:47:34 the problem here is that when in Accessory mode the Android device has 3 options: one bulk interface, one bulk interface + adb and bulk interface + adb + audio output *no input* Feb 19 21:47:52 that is why we need to encapsulate the audio driver with the framebuffer one on top of usb Feb 19 21:48:27 <_av500_> yes Feb 19 21:48:43 <_av500_> on the BBB side, we need a virtual audio driver Feb 19 21:48:47 <_av500_> that hooks into also Feb 19 21:48:55 <_av500_> and into our ADK bridge Feb 19 21:49:05 <_av500_> into alsa* Feb 19 21:50:49 i think a better example is to search usb audio card drivers and look how those are implemented Feb 19 21:54:16 I'm trying that option also. But seems everything finally needs an integration with ALSA. So I just need to be sure if my direction is right. Feb 19 21:59:18 <_av500_> sure Feb 19 21:59:25 <_av500_> but alsa are well defined APIs Feb 19 21:59:43 <_av500_> and its the std linux audio api Feb 19 22:05:59 One more question, if we send both audio and video data in a single endpoint, don't you think the performance will be bad in terms of frame per second? Feb 19 22:06:33 <_av500_> we will see Feb 19 22:06:42 <_av500_> audio needs to be prioritized Feb 19 22:07:06 video you can drop the FPS a bit, i do not remember what resolution we had Feb 19 22:07:21 but praveen had 23 fps think so Feb 19 22:07:21 <_av500_> also there are use cases where there is only audio Feb 19 22:07:30 I see. Thanks Feb 19 22:07:39 <_av500_> imagine making an audio recorder Feb 19 22:07:48 <_av500_> BBB with an analog cape Feb 19 22:07:52 <_av500_> and the UI on the phone Feb 19 22:08:33 <_av500_> ok, need to sleep Feb 19 22:08:37 <_av500_> goodnihgt Feb 19 22:08:45 gn _av500_ Feb 19 22:08:58 Thanks for the suggestion :) **** ENDING LOGGING AT Fri Feb 20 02:59:59 2015
