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
Does anybody know what I’m doing wrong or doesn’t this cape work with the newest Beaglebone Black?
Marty
What does this command produce?
cat /sys/devices/bone_capemgr*/slots

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

This looks like a conflict between HDMI and the audio cape. Are you
"Since this Audio Cape uses the same audio signal from the onboard
optargs=capemgr.disable_partno=BB-BONELT-HDMI"
I'd double check you typed that correctly into uEnv.txt.

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?

Actually, how would I know if this file is being read ok?
The march image its located at /boot/uEnv.txt

Oh, so the file should already exist? What do u mean by the march image…the image I flashed?
With the March "2015-03-01" image, the file you need to modify to stop

I don’t have that file. Do I need to reflash?

That file was in /boot. I’ll move it to /boot/uboot and then add that line. Hopefully it works then.
Stop! Don't do that... It's suppost to be in "/boot/uEnv.txt"...

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...
