Hello all,
Apologies if this is a double post - my last one didn't seem to get through.
I'm trying to get audio working on the AT91SAM9263-EK, using the latest Linux binary download from
http://www.at91.com/linux4sam/bin/view/ ... ingStarted (configured to run from nand-flash).
I can login fine and set volumes with alsamixer. If I do "cat /dev/urandom > /dev/dsp" I can then hear noise. If I do "mplayer /usr/share/gpe-conf/activate.wav" I get some sound. However if I do "aplay /usr/share/gpe-conf/activate.wav" I get a kernel oops:
Code:
Playing WAVE '/usr/share/gpe-conf/activate.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono
Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c3b50000
[00000000] *pgd=23b23031, *pte=00000000, *ppte=00000000
Internal error: Oops: 17 [#1]
Modules linked in:
CPU: 0 Not tainted (2.6.27 #1)
PC is at __wake_up_bit+0x10/0x3c
LR is at unlock_page+0x54/0x60
pc : [<c00506c8>] lr : [<c0062540>] psr: 20000013
etc.
I've tried to insert the soundcore kernel module, but it seems to be compiled against 2.6.20, so complains about mismatching headers. I noticed in the boot up information the line: "FATAL: Could not load /lib/modules/2.6.27/modules.dep: No such file or directory" which may be related??
I've tried older binaries, building my own binaries, trying to load in modules I've built etc. but I keep having this trouble with aplay. The actual app I want to use produces the same fault as aplay, so I figure if I fix one I'll fix the other.
Any help gratefully appreciated!
