**** BEGIN LOGGING AT Sun May 25 02:59:59 2014 May 25 03:10:22 having trouble getting wifi up on beagle (recent debian) iwconfig shows proper ssid but also shows "not associated" how do I get connected? May 25 03:11:08 the network is open.... no wpa, wep, etc. May 25 03:13:11 how did you configure the network interface? May 25 03:13:17 using wicd? May 25 03:13:29 iwconfig? May 25 03:15:08 is the wlan interface up, rfkill off ? May 25 03:15:08 if wicd is running, it may interfere with manually configuring the interface... May 25 03:15:51 wifi_trouble: run wicd-curses if youre in console May 25 03:16:03 how do I tell which method is in use? just using the default as configured in the most recent debian image May 25 03:16:08 may need to apt-get wicd-curses May 25 03:16:17 wicd-curses is in latest build May 25 03:16:24 ah ok May 25 03:17:06 nice! can't get to the network to apt-get, to get to the network May 25 03:17:21 wire ftw :) May 25 03:17:29 ....but the wireless tools do seem to be there May 25 03:18:16 I don't presently have a wired option, if I did it would be preferred May 25 03:18:39 sec, let me catch up on some of your queries May 25 03:22:33 interface is up but as I said reports being "not associated" dhclient thus fails to get an address. May 25 03:34:48 yes, encryption/etc error May 25 03:34:54 or rfkill sometimes May 25 03:35:03 can you run wicd-ncurses or not? May 25 03:35:14 that should search for wifi signals May 25 09:31:52 how can I get sound working without manual config at each boot? I've edited uEnv.txt to load the driver but it still requires manual config. uEnv.txt is here: http://pastebin.com/WRbDSZUp May 25 11:18:09 HI, I am looking for securing linux system , if it has physical access.... May 25 11:19:43 is there any way to lock emmc from reading/writing by externally booted os in beagle bone black. May 25 11:33:36 no May 25 11:34:00 you cannot secure it against somebody who has access May 25 11:34:18 you can of course kill the sdcard slort May 25 11:34:20 you can of course kill the sdcard slot May 25 12:01:41 you could use super glue and glue the sdcard into the slot with a glued readonly lock May 25 14:06:49 you can configure the interconnect firewalls in to revoke access to eMMC (and to the firewall config registers) May 25 14:07:04 that would effectively block access until reset May 25 14:16:10 (MM1 is covered by region 0x40 of the L4-Per firewall, and region 0x41 for its target agent) May 25 14:20:34 oh, against someone with physical access... he'd need the HS version I guess ;) (our TI FAE mentioned something about a minimum order quantity of 500.000 units/year) May 25 14:21:42 securing against physical access... good luck May 25 14:22:55 ketas: well, the HS version requires code to be public-key authenticated and, once properly authenticated, gives it access to an encryption key stored in eFUSE May 25 14:23:18 so that will... complicate things May 25 14:24:03 the details are fuzzy though (no doubt intentionally), and the HS version is only available for high-volume customers May 25 14:30:18 on GP devices the hard part is establishing a root of trust... i.e. making sure your bootloader runs and not an attacker's May 25 14:31:57 (it's kind of sad that these SoC are full of security-shit, yet on GP versions you don't get even the most basic code protection you would find on any $2 microcontroller) May 25 16:06:29 jgalt what kind of audio device? May 25 20:18:14 On beagleboard, Linux sysfs contains a directory named /sys/devices/bone_capemgr.9/. Does anyone knows what the number '9' means ? Is this number constant ? May 25 20:18:33 yes its constant .. dunno why May 25 20:19:20 .. its 9 May 25 20:23:46 is it board specific or kernel driver specific ? May 25 20:25:46 its consistent across beagles from what I understand .. standard to the cape_mgr driver May 25 20:26:42 one explanation here (not verified) : http://markmail.org/message/4ldnxum3nupllx7j#query:+page:1+mid:4ldnxum3nupllx7j+state:results May 25 20:41:09 is anybody using rowboat? just joined the channel there and there's only two other people :/ May 25 20:43:55 does the linux kernel task switch when there is a read cache miss? May 25 20:44:07 data read cache miss, i.e.? May 25 21:21:50 a/away May 25 23:27:51 anyone an i2s expert here? i need help getting a codec to talk to a dac over i2s, both have configuration screens but i dont know what to change settings too May 25 23:28:18 ultimatly they connect to beagle but no there yet May 25 23:28:22 not May 25 23:30:29 does the linux kernel task switch when there is a data read cache miss? May 25 23:31:16 dogrocket: did you mean i2c? May 25 23:31:40 did you get the datasheet for the dac and read up on the i2c registers? May 25 23:31:51 no just simple i2s... i2c should be needed i dont think May 25 23:32:02 yeah, looks like greek to me.. lol May 25 23:32:13 shouldnt May 25 23:33:14 dont even have to dig that deep into registers, it has drop downs for both to select proper settings May 25 23:33:30 so what is the problem? May 25 23:34:10 well i need to know what i should set mclck, blck, and fs and other stuff too.. so they both communicate properly May 25 23:35:04 is this a dac you're hooking up via a cape? May 25 23:35:06 i have a variety of settings.. so can make them what i want. within both devices ranges May 25 23:35:47 well the codec is going to beagle, its a maxim98089, and it has 2 i2s outputs, one goes to beagle and one goes to dac May 25 23:36:57 the dac is a ti peice that can act as a dac in a sense to other codecs etc May 25 23:44:14 why would someone get a "operation not permitted" when they modprobe uio_pruss when it worked the day before? **** BEGIN LOGGING AT Sun May 25 23:46:11 2014 May 26 00:02:56 finally got my bbb running properly w/ android 4.3 ... and sgx works, but the16 bit graphics are crappy :/ May 26 00:06:15 nvrmd. somehow I didn't have it enabled in the tree. **** ENDING LOGGING AT Mon May 26 03:00:00 2014
