**** BEGIN LOGGING AT Thu Jun 12 02:59:59 2014 Jun 12 04:14:37 * karki wakes up with a terrible fever :'( Jun 12 06:26:49 karki: get well! Jun 12 06:31:16 morning channel Jun 12 06:38:48 vvu : I'm trying ;) Jun 12 06:42:05 * vvu just deleted all the spams from last years blog Jun 12 07:22:57 panto: i was looking to make changes to the UBoot environment variables. i made changes using printenv and setenv, but these changes don’t last after a reboot Jun 12 07:23:19 modify uEnv.txt Jun 12 07:23:33 recent versions of u-boot support saveenv as well Jun 12 07:24:38 panto: thanks ! Jun 12 07:27:10 also panto , i found quite a few blogs on loading the dtbos, couldn’t come up with much on device trees. suggestions ? Jun 12 07:27:55 err, what do you mean? Jun 12 07:29:43 there's plenty of info on device tree Jun 12 07:30:14 http://lwn.net/Articles/572692/ Jun 12 07:30:16 and similar Jun 12 07:31:15 panto: when you once said that capemgr will be phased out in future kernels, how will overlays be loaded then? Or would the device tree be have to replaced everytime we try and do something new? Jun 12 07:33:36 panto: not dt in particular, but loading it. for example i found boardfile, fdtfile, findfdt and fdtbase as variables that i will have to change to load my own dt. plus, do i have to change the address of the fdtaddr if i have anuj.dtb in boot/uboot which i need to load ? or is that the address to which the fdtfile is loaded to ? Jun 12 07:44:08 panto: For synchronization in reads (read blocks till the first quantum of buffer is filled and unmapped at ISR), what would be a better choice of locking? mutex, semaphore or waitqueue? Jun 12 07:47:39 Abhishek_, there are new overlay patches Jun 12 07:47:51 with a generic overlay loader Jun 12 07:48:17 anujdeshpande, you just replace the dtb in the boot partition Jun 12 07:48:21 Abhishek_, it depends Jun 12 07:48:34 on reads, probably a waitqueue Jun 12 07:48:39 but locks must be taken Jun 12 07:48:46 indeed Jun 12 07:48:48 then you use a mutex Jun 12 07:49:01 locking can be complicated Jun 12 07:49:02 panto: ok Jun 12 07:49:05 I want to make /dev/beaglelogic accessible to *just* one owner Jun 12 07:49:39 ok Jun 12 07:49:45 got to run to the stores Jun 12 07:49:46 bbl Jun 12 07:49:54 lunch? Jun 12 07:50:33 too early for that Jun 12 07:51:08 ah, my bad Jun 12 08:46:04 any hint where is the flasher script for the eMMC ? Jun 12 08:46:25 that runs automatically from the mmc Jun 12 12:41:46 vvu: /opt/scripts Jun 12 12:42:20 Somewhere in there Jun 12 13:05:32 VoltVisionFrench: are you here? Jun 12 13:05:57 DiegoTc, how are you! Jun 12 13:06:18 great! trying to contact you since yesterday Jun 12 13:06:47 * DiegoTc assumes Jason wants to kill me :p Jun 12 13:08:58 VoltVisionFrench: have time to talk? Jun 12 13:11:17 Yes and no. I have an employee here and we are working on a bunch of things...so I cant do realtime chat right now....but what I can do is do a few quick things like setting up a Skype meeting time with you and the Guatemalan professor or maybe quickly answering a question. We can talk in more detail/chat later maybe during lunch. Jun 12 13:11:55 Is there an update I should look at right now? Jun 12 13:12:10 Should we setup a Skype time to talk with the Guatemalan professor? Jun 12 13:12:30 Do you want to SKype right now real quick (or google hangout)(. Jun 12 13:12:32 ? Jun 12 13:15:09 guys do you know how to set up wpa_supplicant with 802.1x EAP ? Jun 12 13:15:24 i am trying but getting ioctl[SIOCSIWENCODEEXT]: Invalid argument Jun 12 13:15:44 i am using RTL8188CUS wlan adapter on the BBB Jun 12 13:17:38 Hi VoltVisionFrench I can caht right now, not talking :( Jun 12 13:18:15 I send you an email, telling you tjhat we could have the skype or hangout on Monday with the people of guatemala Jun 12 13:18:24 is that ok for you? Jun 12 13:18:52 I uploaded a new branch today on the morning, but it's only code Jun 12 13:22:19 vvu, Its funny you mention the RTL8188CUS. I was just trying to get that to work the other night on the BBB, but I couldnt get it working and I gave up. I was referencing the supplicant stuff here (http://elinux.org/BBBWiFiConfigs)...but I didnt get it to work...admittedly I was using the Beta kernel, so this might have been why it didnt work. Jun 12 13:22:50 vvu, let me know if you get it working...cuz I might be able to learn from you. Jun 12 13:22:52 ! Jun 12 13:23:28 DiegoTc, yes..monday sounds great. I will respond to your email today and set it up. Jun 12 13:24:11 VoltVisionFrench: if i have any findings i will ping you Jun 12 13:24:16 i have the stock stuff on my BBB Jun 12 13:25:42 vvu, I had updated to the beta kernel (3.14.4-bone4) which might not be a good idea...because it also broke my USB audio. Jun 12 13:26:03 I should try again now that I moved back to the outdated 3.8 kernel. Jun 12 13:26:46 lsusb Jun 12 13:26:51 wrong window ! Jun 12 13:27:27 Bus 006 Device 035: ID 0e79:1105 Archos, Inc. Jun 12 13:27:29 * Abhishek_ wonders if BeagleLogic would work on the beta kernels... Jun 12 13:27:36 vvu, when I did "find -iname *RTL8188*", it did NOT list the "CUS", but it had some other options like ... Jun 12 13:27:37 ./media/rootfs/lib/firmware/rtlwifi/rtl8188eufw.bin Jun 12 13:27:47 ./media/rootfs/lib/firmware/rtlwifi/rtl8188efw.bin Jun 12 13:27:54 ./lib/modules/3.14.4-bone4/kernel/drivers/staging/rtl8188eu Jun 12 13:28:01 ./lib/firmware/rtlwifi/rtl8188efw.bin Jun 12 13:28:07 ./lib/firmware/rtlwifi/rtl8188eufw.bin Jun 12 13:29:28 Abhishek_, yesterday we found out that the beta kernel did not have this "/sys/devices/bone_capemgr.*/slots", so it broke some stuff in the PyBBIO library Jun 12 13:29:55 ...not sure if the cape manager missing is temporary or permanent...? Jun 12 13:29:57 VoltVisionFrench: capemgr is to be phased out in future kernels Jun 12 13:30:11 (as told by panto) Jun 12 13:32:17 Abhishek_, thanks for the inside scoop! I need to tell AlexHiam because he is using "export SLOTS=/sys/devices/bone_capemgr.*/slots" in his PyBBIO library Jun 12 13:32:35 ...but in the new kernel its gone! Jun 12 13:32:44 yeah Jun 12 13:42:04 rseethamraju: which part are you working on right now? Jun 12 13:42:28 the spi Jun 12 13:42:34 then gstreamer Jun 12 13:42:35 why? Jun 12 13:43:50 as in an SPI library. Then I’ll be working on gstreamer to stream video/capture a pic from a camera connected to the bbb Jun 12 13:43:50 never mind, just wanted to know Jun 12 13:43:56 ok Jun 12 13:45:13 using a webcam or camera cape? Jun 12 14:35:57 Abhishek_, do you agree that if we focus on the webcam, that would service >99% of the people...and if we service the camera cape, that would service <1% of the people...maybe we can do both, but I think the webcam would be a first priority. Does anyone disagree with this? Jun 12 14:36:55 I would go with the webcam Jun 12 14:38:12 camera capes are good for custom hardware but then it's something not readily available or reusable Jun 12 14:40:11 I have personally worked with a OV7670 camera module (with a STM32) but the results weren't encouraging Jun 12 14:41:36 i vote webcam Jun 12 14:41:48 camera cape never heard people using it around #beagle Jun 12 14:42:34 the beagleboard doesn't have a CSI like a rpi, so the camera capes are basically GPMC hacks with a FPGA coprocessor... Jun 12 14:42:55 webcam Jun 12 14:43:18 and I don’t have the cape anyway Jun 12 14:43:59 IIRC some guy in TI managed to use a camera module by directly connecting it via PRU Jun 12 14:44:28 he could benefit from my beaglelogic kernel driver :) Jun 12 14:51:34 leaching wav files from an I2S communication could be a similar exercise that I have planned Jun 12 16:34:09 panto: do you have any experience with usb drivers ? Jun 12 16:34:36 what is this about? Jun 12 16:35:59 i have some questions about the probe function how does it work Jun 12 16:36:16 it says that probe is called when a new usb device that matches the device table is connected Jun 12 16:36:32 but for me the probe function is called twice, probe is per interface or per device Jun 12 16:39:58 no idea Jun 12 16:40:08 are you sure there are no two devices? Jun 12 16:51:57 nop, maybe I am just tired and doing something stupid :) Jun 12 19:25:00 jkridner: have time? or quite bussy? Jun 12 19:25:49 I answer your email yesterday. Sorry for the delay. Tonight I'm pushing new code to the brancj Jun 12 19:25:52 branch Jun 12 20:26:20 <_av500_> praveendath92: welcome back Jun 12 20:27:07 Hello _av500_ :) **** ENDING LOGGING AT Fri Jun 13 02:59:59 2014
