Hi, All
Has anyone has experiences of installing alsa drivers of VXpocket
series card into an arm-linux platform?
My vxloader gives me error message when I loads firmware for VXPocket
440 card. The following are the detailed descriptions of what I did in the
installation of ALSA package and what I got out of it. Please help me out.
I can not figure out what goes wrong exactly. I'm pulling my hairs. Thanks
a lot.
A. What I did in the test of VXpocket 440 sound card.
(1) I tested VXpocket 440 sound card on the Stargate platform
(http://platformx.sourceforge.net/).
(2) On the stargate platform, I ran a linux version developed at UCLA
(http://lecs.cs.ucla.edu/~jelson/stargate/ucla-release5/).
(3) I used the latest version 1.0.2 of ALSA package
(http://www.alsa-project.org/) Driver, Library, Utilities, Tools,
and Firmware.
(4) For a particular reason, static alsa library is built. All utilities
and tools (including vxloader) are statically linked to alsa library.
(5) Firmware was put in directory
'/usr/local/share/alsa/firmware/vxloader/'.
To be consistent with firmware location, firmware loader vxloader is put
in directory '/usr/local/bin/'.
(6) To the end of /etc/modules.conf, I appended
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-vxp440
# module options should go here
# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
(7) I installed PCMCIA device driver definitions by
cp /usr/src/alsa-driver-1.0.2/pcmcia/vx/vxp440.conf /etc/pcmcia
B. What I got from the test.
(a) Modules for vxp-440 are properly inserted
'cat /proc/modules' displays the following modules
snd-vxp440 1008 0 (unused)
snd-vx-cs 6336 0 [snd-vxp440]
kfusd 14928 0 (unused)
snd-vx-lib 23104 0 [snd-vx-cs]
snd-pcm 57600 0 [snd-vx-lib]
snd-timer 14592 0 [snd-pcm]
snd-hwdep 4736 0 [snd-vx-lib]
snd-page-alloc 3552 0 [snd-vx-lib snd-pcm]
snd 30576 0 [snd-vx-cs snd-vx-lib snd-pcm snd-timer snd-hwdep]
soundcore 4032 0 [snd]
cs89x0 7968 1
(b) 'cat /proc/asound/devices' displays the following devices
0: [0- 0]: ctl
4: [0- 0]: hardware dependent
33: : timer
(c) 'cat /proc/asound/hwdep' displays the following
00-00: VX Loader (VXPocket440)
(d) 'cat /proc/asound/card0/vx-status' displays the following state
Digigram VXPocket440 at 0xf6000000, irq 153
DSP audio info:
Input Source: Line
Clock Source: Internal
Frequency: 0
Detected Frequency: 0
Detected UER type: Consumer
Min/Max/Cur IBL: 0/0/0 (granularity=0)
(e) However, when I execute command 'vxloader' to load firmware,
I got the following error messages
ALSA lib hwdep.c:151:(snd_hwdep_open_noupdate) Unknown HwDep hw:0
vxloader: conf.c:3075: snd_config_update_free: Assertion `update->count > 0 &&
update->finfo' failed.
Aborted
(f) '/proc/asound/card0/oss_mixer' does NOT appear.
'/proc/asound/oss/devices' is empty.
I think this is due to the failure of loading firmware.
