I have sound coming out of my little linux box through the audiostix. sweeeet.
How to do it:
Recompile buildroot to include aumix and bplay
modprobe snd-pxa2xx-ac97, snd-pcm-oss, and snd-mixer-oss
set bolume to (say) 60% with aumix -v 60
then bplay a wav file with bplay /path/to/wav
wow. This is awesome!
Now... to compile an audio language... like (say) supercollider, pd, or chuck. :)
weeeeeee!
building gumstix buildroot has been fun. :) The only problems for me were:
that the uboot includes are of the #include <linux/config.h> type. This caused the compiler to try to include the config.h from my ubuntu linux headers rather than those in the buildroot directory.
I had to do a mkdir -p ./build_arm_nofpu/root/etc/udev/rules.d/ in the buildroot directory or one of the install scripts would puke.
I'll file bugs as soon as I can figure out who maintains this. :P
Gumstix says HI! Connection via bluetooth in OS X is up while I wait for Debian to download some packages. All I had to do to connect:
1. Go to bluetooth prefs in OS X
2. Click Set up BLuetooth Device
3. Select "Any Device"
4. Click "Passkey Options..."
5. Select the "Use a specific passkey" radio button
6. Use "1234" (minus quotes) as the passkey
7. Open terminal
8. type: ls /dev/tty.*
9. One of those will correspond to the gumstix (/dev/tty.Gumstix-1 for me)
10. type screen /dev/tty.Gumstix-1 9600
(9600 is the baud rate. I am not sure if the gumstix BT module will go faster than that)
11. Login as root
12. Default password is "gumstix"
13. Welcome to gumstix linux!
My Gumstix has arrived. I'm firing up Debian linux in parallels so I can talk to it... Notes to come.
