Re: [beagleboard] Re: Beaglebone Black can't get USB audio to work
I got the kernel recompiled with disabled DMA and installed it. Sound now works fine. For anyone else wanting to do this I followed Roberts notes and used a couple other pages to help with figuring out some details such as installing things needed for the cross compile on a Ubuntu PC: http://elinux.org/Building_BBB_Kernel http://wiki.beyondlogic.org/index.php/BeagleBoneBlack_Building_Kernel I didn't mess with TFTP as both those pages show. After the cross compile I transferred the new kernel file to the BBB with Filezilla (after I backed up the system in case of trouble) and installed with dpkg -i ... as Robert suggested.

Re: [beagleboard] Re: Beaglebone Black can't get USB audio to work
Thanks! I take it that is done on the BBB itself? (rather than cross compiled) Any issue with doing this over ssh? (particularly the selecting of kernel configuration boxes) I saw in another thread https://groups.google.com/forum/embed/?place=forum/beagleboard=true=true=false=true=http%3A%2F%2Fbeagleboard.org%2Fdiscuss#!category-topic/beagleboard/usb/HQnLSvyYISI that it might be possible to achieve the same thing by adding *musb_hdrc*. *use_dma*=n to the kernel cmdline. I have only fiddled a bit with this on desktops and the BBB is a little different. Can I add this as to uEnv.txt as an addition to the optargs=... line? That would be a lot simpler, at least to test and verify that this is the issue, than recompiling the kernel. If not there, where do I place that? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] Re: Beaglebone Black can't get USB audio to work
Apparently, from a little searching and reading others are having similar trouble and the issue is DMA for the USB audio - it needs to be disabled (I think...). This requires recompiling the kernel with this disabled. Haven't compiled a kernel before so am looking for some detailed instructions on this and replacing the existing kernel (would like to keep the rest of the configured system if possible). Anyone have any good links on doing this? I have found several places that give the line setting the option of disabling DMA and I think I could add that to detailed kernel cross compiling instructions... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] Beaglebone Black can't get USB audio to work
Trying to add USB audio device to BBB. I am running this headless - no HDMI display, no direct keyboard or mouse. USB audio device is C-Media. Have a powered USB hub. Have an Arduino board connected by USB but don't think it affects this issue. USB audio device is seen by aplay -l and aplay -L but trying to use it doesn't work and usually hangs the system requiring a power cycle.

[beagleboard] How to troubleshoot crash?
Running 3.14 ubuntu with asterisk image latest from http://beaglebone-asterisk.raspbx.org/ but support seems to be going away. Have added some simple scripts to talking to an Arduino board but think the problem is more basic. Latest image ran ok for about a month but now is crashing almost daily. This is headless and when it crashes I can't access it although it may still be running - I'm not sure... Hardly any experience looking at logs, etc. How do I figure out what is going on and how to fix - i.e. where to start? If the fix is too involved I may just abandon asterisk for now and go with a maintained version of ubuntu (which one?) if that's what's needed for a stable system. The other scripts are more important now and I could run asterisk on a real PC box. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

Re: [beagleboard] Automatic shutdown options for loss of power?
I already have a big battery in the UPS so I don't need another one. What I need is control. I have an Arduino connected to the BBB for I/O that could help with this. If the Arduino could interrupt the power to the BBB (or trigger the boot process some other way) that would handle power up. It could also handle delay for power down. Something like this: BBB and Arduino powered from UPS. Another wall wart power supply from AC line to Arduino to sense state of AC line Upon loss of AC line the arduino would delay an amount of time and send a signal to the BBB to trigger shutdown. Time delay would prevent shutdown for short line drops. After time to shut down it would drop power to the BBB. Upon regaining AC line it would close switch to apply power to BBB. A small delay would probably be a good idea to eliminate possibility of very short off times. The switch could be a relay or solid state switch. And the Arduino could be any microprocessor.

Re: [beagleboard] Automatic shutdown options for loss of power?
That is pretty limited. Sounds like just punting the software and going with a mostly hardware solution would be just as easy but then I am a hardware guy. I think a UPS with auto shutdown AND restart capability would be something a lot of people would want but I could be wrong. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.

[beagleboard] Automatic shutdown options for loss of power?
Recently lost power and corrupted my sd card badly and had to start over. I have seen the battery "UPS" for BBB type but don't need another battery. I have a small APC UPS for the BBB, DSL modem, a VOIP box, and a router but the UPS does not have a comm port to report status to the BBB. Would like to set up so that when the AC power drops the BBB will shutdown in 5 minutes (most outages are shorter but this is still much before the UPS runs out of power). If the power is restored before that continue to run. When power is restored start up. With an additional wall wart power supply I could generate a logic level signal for when the AC line is ok (input to UPS). Does anything like this exist? If not, anything similar enough that I could hack up the scripts a bit and get there? Would rather not have to start from scratch. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
