I want to use Bluetooth, but I am struggling with no example code. Let me know if you can get the code or get the information. May 22 13:06:35 Hi May 22 13:06:43 I am using BBB Rev C May 22 13:07:41 And I am getting these messages May 22 13:07:53 How can I disable hdmi audio? May 22 13:16:08 hi May 22 13:16:33 I am getting these messages on my BBB Rev C May 22 13:16:35 [ 516.227251] hdmi-audio-codec hdmi-audio-codec.2.auto: ASoC: can't set i2s-hifi hw params: -19 May 22 13:16:44 How can i disable hdmi audio ? May 22 13:16:52 someone please? May 22 13:25:41 uhaider: look at your /boot/uEnv.txt May 22 13:32:20 Hmmm.. maybe that's just for Disabling HDMI altogether... sounds like you just want to knock out the audio... May 22 13:42:27 sorry I'm not more help Fairly new to BB myself. If you lurk for a while someone with more experience will probably answer when they check the channel. May 22 13:52:13 you probably need to set some kernel command-line parameter . if you want to use the HDMI for video still, else you can nuke the HDMI altogether with a block on the virtual cape that is loaded May 22 14:36:57 hello everybody, is it possible to boot the beagleboard x15 with a bluetooth driver so a keyboard is usable before/while the linux kernel is booting? May 22 14:42:10 I very much doubt that May 22 14:42:41 you'd have to patch uboot .. theoretically possible, but wow .. yeahno, don't fancy that. May 22 14:42:52 a wireless keyboard would work. Possibly even a bluetooth low energy receiver that is configured for HID mode and not HCI May 22 14:43:09 you -might- partially succeed with an initramfs .. May 22 15:40:14 no patching uboot? May 22 15:40:21 patching uboot sounds like fun! May 22 15:50:13 loading the driver in initramfs may be within my limited brain power. I'll check it out. I rather not mess w u-boot. May 22 16:12:57 patching uboot wouldn't get you a working keyboard *after* uboot May 22 16:15:30 I think the main issue is that getting anything bluetooth-related working requires more than just a driver, since it needs to be paired May 22 16:16:05 so you may be dependent on userspace services anyway May 22 16:16:19 why do you need a keyboard working sooner than that though? May 22 16:16:53 zmatt: good point .. you'd have to hard code aka hack a LOT of stuff :D May 22 16:17:31 most of boot is done when userspace is already available anyway May 22 16:17:55 aka too late for OP May 22 16:18:15 maybe OP can explain what the motivation is May 22 16:21:52 we're trying to minimize the peripherals cabled to the device. we're also aiming to have the main storage encrypted. the user would supply the password through the keyboard. May 22 16:22:15 why not a wireless kb rather than bluetooth .. May 22 16:22:31 veremit: typing a password over that doesn't sound very secure :P May 22 16:22:39 newp May 22 16:24:28 raffo: you can cram lots of stuff into initramfs of course May 22 16:25:51 alternatively, you could use the new-ish ext4 encryption support to just encrypt some directories instead of the entire filesystem May 22 16:41:27 ah, interesting. Thank you, I'll check it out. May 22 16:42:09 you'll want a recent kernel for that May 22 17:30:58 I haven't dealt with the BB UART in a while, I'm probing UART2 TX with an oScope and submitting an "echo > /dev/ttyO2", but I see no data on the line May 22 17:31:11 What am I missing? May 22 17:48:21 MiddleMan: have you enabled the UART? use the showpin utility to make sure your pinout is correct May 22 18:03:12 is there a bash function or a directory I can check, isnt showpin a C utility? May 22 18:17:12 MiddleMan: have you checked Rx .. and all the other UART pins? .. what does your uEnv.txt say [pastebin/etc] May 22 18:17:30 dmesg|grep 'cape' May 22 18:33:20 (it's "show-pins", and no it isn't) May 22 18:33:37 hmm, does rcn actually include it in the default images? May 22 18:34:48 hi May 22 18:35:23 anybody using GNU Radio on BBB? May 22 18:38:07 I don't know if my messages were getting through, uEnv: https://pastebin.com/bdGXuVPT May 22 18:39:33 and the dmesg output: https://pastebin.com/hBsPec71 May 22 18:39:48 I don't see any reference to UART in there... May 22 18:41:20 MiddleMan: show-pins is a perl script you can find here -> https://github.com/mvduin/bbb-pin-utils May 22 18:43:03 your uEnv line to load the BB-UART2 cape has the wrong syntax May 22 18:43:39 examples of the correct syntax (for both 3.8 kernels and 4.x kernels) can be found in the comments below it May 22 18:44:23 note btw that you can also configure the pins at runtime using cape-universal May 22 18:44:55 (loading any cape using bone_capemgr.enable_partno will afaik automatically disable cape-universal) May 22 18:45:06 *loading any overlay I mean May 22 18:48:10 I didn't notice that, thank you!
