Hi folks,
Using image : http://www.angstrom-distribution.org/demo/beagleboard/uImage And rootfs: http://www.angstrom-distribution.org/demo/beagleboard/Angstrom-Beagleboa rd-demo-image-glibc-ipk-2009.X-test-20090203-beagleboard.rootfs.tar.bz2 And package: alsa-utils-aplay Attemping to record using the command: arecord -D ctl.mixer0 -t wav -c 2 -r 44100 -f S16_LE -v test.wav Or playing using command: aplay wavefile.wav Things blow up with the following message (stack trace trimmed for brevity): r...@beagleboard:~# arecord -D ctl.mixer0 -t wav -c 2 -r 44100 -f S16_LE -v test .wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Hardware PCM card 0 'omap3beagle' device 0 subdevice 0 Its setup is: stream : CAPTURE access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 16 buffer_size : 22052 period_size : 5513 period_time : 125011 tstamp_mode : NONE period_step : 1 avail_min : 5513 period_event : 0 start_threshold : 1 stop_threshold : 22052 silence_threshold: 0 silence_size : 0 boundary : 1445199872 Unable to handle kernel NULL pointer dereference at virtual address 00000070 pgd = c36d0000 [00000070] *pgd=834e6031, *pte=00000000, *ppte=00000000 Internal error: Oops: 17 [#1] Modules linked in: CPU: 0 Not tainted (2.6.27-omap1 #2) PC is at snd_pcm_common_ioctl1+0x9b4/0xf98 LR is at snd_pcm_capture_ioctl1+0x3d8/0x3fc pc : [<c025c5e8>] lr : [<c025cfa4>] psr: 60000013 sp : c34e5dd8 ip : c0844123 fp : c34e5efc r10: 0001c670 r9 : c34e4000 r8 : c0033dc4 r7 : 00000000 r6 : 00000004 r5 : c34e5de0 r4 : 00026128 r3 : c0844123 r2 : 40044145 r1 : 00000084 r0 : c34e5de0 Flags: nZCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment user Control: 00c5387f Table: 836d0018 DAC: 00000015 Process arecord (pid: 2771, stack limit = 0xc34e42e8) Stack: (0xc34e5dd8 to 0xc34e6000) As you can see, it prepares the header no problem then dies when actually trying to record. Have tried moving to: http://www.angstrom-distribution.org/unstable/autobuild/beagleboard/uIma ge-beagleboard.bin With same rootfs - and audio recording/playback works! However, 'unstable' is an appropriate name for this autobuild image...it halts 4 times out of 10 on the following line (serial output): Power Management for TI OMAP3. Also tried this revision of 2.6.27: http://www.angstrom-distribution.org/unstable/autobuild/beagleboard/uIma ge-2.6.27-r13-beagleboard.bin However, same errors as above. Any ideas? Things were working some time ago, but I guess the 2.6.27 release got broken at some point (which, shame on me, I am unable to identify right now) -- I'll try some earlier revisions like r10 and see if that helps. Would be good if issue could be resolved in a new release, however... _______________________________________________ Angstrom-distro-users mailing list Angstrom-distro-users@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-users
