I'm tring to get sound working on a "ADSP-BF518F EZ-BOARD REV 1.0".
But it seems that /dev/dsp does not exist on the file system.
ERROR: failed to open DAC device /dev/dsp
Any help would be greatly appreciated.
I've included some info about my setup below.
kernel: Linux release 3.0.8-ADI-2011R1, build #20 Sat Apr 28 15:39:53 EDT 2012
toolchain: bfin-uclinux-gcc release gcc version 4.3.5 (ADI-2011R1-RC4)
user-dist: release , build #6 Sat Apr 28 15:39:01 EDT 2012
ssm2602 0-001b: probe
i2c-core: driver [ssm2602] registered
bfin-i2s bfin-i2s.0: no platform_data
ALSA device list:
No soundcards found.
root:/proc/asound> cat devices
33: : timer
root:/proc/asound> ls /dev/snd
The drivers are built in to the kernel. I also tried building them
as modules, with the same results.
root:/proc/asound> cat /lib/modules/3.0.8-ADI-2011R1/modules.builtin
On the board, every switch on SW15 is set to ON.
#if defined(CONFIG_SND_SOC_SSM2602) || defined(CONFIG_SND_SOC_SSM2602_MODULE)
Just as a sanity check, I put
#error "I got here"
inside the the code above, to check that it was being included.
It does indeed hit the #error statement.
