Audio Cape on BBB rev C

[Marty Linuxhippy]

Hi!  I'm new to the BBB but not to Linux as I've been using it for years.  I just bought the Beaglebone Black Rev. C and updated it by flashing the newest Debian release from 2015-03-01.  So now I have kernel 3.8.13-bone70 and just bought an audio cape for this off eBay.  The seller said it worked with his rev B BBB.

I'm trying to follow this page:

http://elinux.org/BBB_Audio_Cape_RevB_Getting_Started

But I'm getting this error:

root@beaglebone:~# echo BB-BONE-AUDI-02 > /sys/devices/bone_capemgr*/slots
-bash: echo: write error: File exists

Does anybody know what I'm doing wrong or doesn't this cape work with the newest Beaglebone Black?

What does this command produce?

cat /sys/devices/bone_capemgr*/slots

[Marty]

Not what that tutorial listed.  My audio cape was plugged in when I did cat /sys/devices/bone_capemgr*/slots:

 0: 54:PF---
 1: 55:PF---
 2: 56:PF---
 3: 57:PF---

 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI

*******************************************************

I had already downloaded and compiled BB-BONE-AUDI-02-00A0 with no errors.  That echo command produced the first error.  I don't seem to be getting line 6 from that cat command that the tutorial lists:

6: ff:P-O-L Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN

This looks like a conflict between HDMI and the audio cape. Are you
certain you disabled HDMI as instructed in that tutorial?

"Since this Audio Cape uses the same audio signal from the onboard
HDMI interface, you need to disable the audio portion of the HDMI by
edit the uEnv.txt at /boot/uboot. Add this line to the uEnv.txt file:

optargs=capemgr.disable_partno=BB-BONELT-HDMI"

I'd double check you typed that correctly into uEnv.txt.

[Marty]

I copied and pasted that into /boot/uboot/uEnv.txt but created that file with nano since it didn't exist.  What should the permissions be on this file?

With the March "2015-03-01" image, the file you need to modify to stop
loading the pins is located at "/boot/uEnv.txt"

Stop! Don't do that... It's suppost to be in "/boot/uEnv.txt"...

[Marty]

Yeah... That didn't work.  No harm done since I just copied the file.  So how do I get the file that should be in /boot/uboot?

You don't.. Everything is in /boot/uEnv.txt now, just open it and uncomment the line to disable HDMI audio.

That file isn't on my install in that location.  I'll redownload the flash file tonight and flash again.  Where should I download from?  This is where I got it before:

https://rcn-ee.com/rootfs/bb.org/release/2015-03-01/lxde-4gb/BBB-eMMC-flasher-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img.xz

I checked the md5sum code and it checked out.

The flashing did only take 8 minutes on my rev C and I read it should take 25045 minutes.  Maybe that's a bad image?

that should be 25-45 minutes.

Things average 5-6 minutes a GB...

[Marty]

Good... Then 8 minutes is ok on the rev c.  I was thinking those numbers musta been good for the rev b.  Think that's an OK download place...BeagleBoard.org took me there?

><>Sent From Marty's S3<><

ok, I think I got it by NOT following that tutorial and following advice here.  Now I got this:

Which part of the tutorial did you not do? Note that it is a wiki, so
when things change, you can always update the tutorial.

I unconsumed both lines under audio cape but now mplayer doesn't work so I'm not thinking this wiki needs to be revised by me yet.  The wiki is for the rev b and not my c, though.

The wiki was written for the old may 2014 release, the march 2015 is now the official release, it will take time for 'all' wiki's will be updated. Please update it for us. ;)

Don't overwrite old content though. Be sure to note that for your

Yeah I'm not sure what I did is the correct way of doing things.  Since I don't have sound yet I'm thinking not but maybe somebody will build on that and set me straight :)

The easiest thing to do is add the value of `cat /etc/dogtag` as that tells everyone what version they have and how it's setup.

[Jesse Cobra]

Did you disable HDMI audio?

What does aplay -l (or is it -L) output.

Does speaker-test work?

[Marty]

HDMI audio appears to be disabled since BB-BONELT-HDMIN shows up with cat /sys/devices/bone_capemgr*/slots.  That was a good idea, Jesse, about checking with aplay -L.  I hadn't tried that for this (though that is how I got sound to work through a cheap USB adapter) until now.  Unfortunately, it does not list any of the devices that that capemgr lists and no sound works except for a USB adapter (mplayer -ao alsa:device=default=Device -playlist filename.pls is how u stream internet music with a USB soundcard).

So does the audio cape work on the  rev C with the may 2014 image?

><>Sent From Marty's S3<><

[Colin Bester]

Has anyone come right using audio card (rev B) together with 4DCAPE-43T and BBB Rev C running kernel 3.8.13-bone70?

My setup works flawless using kernel 3.8.13-bone50 but after updating to use 3.8.13-bone70 there seems to be an issue when LCD is connected.

"aplay -l" shows audio device and running "aplay mytunes.wav" just makes a single click sound and nothing more (no music).

If I disconnect the LCD then aplay works just fine.

On prior kernel I did modify BB-BONE-AUDI-02 as the dts file specified exclusive gpio1_18 and gpio1_19 use (and as far I recall, these pins weren't even used) causing conflict with LCD Cape overlay - until updating kernal to bone70.

dts snippet:

        exclusive-use =
                /* the pin header uses */
                "P9.31",        /* mcasp0: mcasp0_aclkx */
                "P9.29",        /* mcasp0: mcasp0_fsx */
                "P9.28",        /* mcasp0: mcasp0_axr2 */
                "P9.25",        /* mcasp0: mcasp0_ahclkx */
                /* the hardware ip uses */
                /*"gpio1_18", "gpio1_19",*/

Hello Colin.

 

Keenly interested in getting a known good setup. Which distro/rfs package were you using with that kernel?

 

Thx++

[Colin Bester]

No problem. I am not at my desk right now but will forward info once I'm back at desk.

Pretty silly of me not to state that I'm running the Debian distro as this is an important piece of the equation :-)

Excuse my ignorance but what is 'rfs'?

What works for me:

Debian emmc flasher image: BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img

BBB Rev C Board

4D Systems 4DCAPE -43T LCD4

Audio Cape (Rev B1)

I basically followed instructions for audio cape from http://elinux.org/BBB_Audio_Cape_RevB_Getting_Started but needed to edit the dts file before compiling, removing the exclusive use of gpio1_18 and gpio1_19.

Some more follow up.

If I disable (via capemgr) loading of BB-BONE-LCD4-01 with LCD connected then audio works - running dmesg after trying to run aplay with and without BB-BONE-LCD4-01 loaded shows two different results.

With BB-BONE-LCD4-01 loaded (enabled):

Running same test on 3.8.13-bone50 shows no such error.

Note specifically error message regarding pinctrl-single 44e10800.pinmux with LCD4 loaded.

Is this a red herring or indication of conflict?

Excellent stuff. Thank you.  The dmesg spw below is from your bone70 installation (?). Let me try and get that bone50 set up to work first.

 

rfs == root file system (in case you were using something generated by Buildroot for example)

Some more follow up.

Ah, gotcha - you had me there with rfs :-). 

yes the dmesg outputs shown are using the bone70 installation. 

glad to have someone else looking at this as I may just be missing something simple - I am wanting to move up to bone70 to make use of the improved cloning scripts as I need to clone quite a few boards in the very near future.

[Colin Bester]

I decided to create a new post specifically to this issue and version as this thread covers a huge span of time with many updates in between.

LDC/Audio Bust?

Hi all ,

I am working on the beagle bone black ,actually what i want to do is ,play a audio in BBB. i am using Wolf son audio card to interface with the BBB, by using YOCTO ,the card specific information i given in .dts or .dtsi file  file actually the card is specific to raspberry pi but i want  to use with BBB .In wolfson card having PCM port there is no PCM port  on BBB , i'm using MCASP to interface the card with BBB the data transmission through i2c .i build images in yocto i took that images and booting the board after booting the kernel  i checked in /proc directory in this there is no asound and cards. can you please tell me the what i was doing wrong in this .

 can you please give me the suggestion ,how to play the audio by using that card .
