I have now joined the ranks of troubleshooting HDSP owner. I
have a cardbus HDSP (rev 0b) with a Multiface. IBM Thinkpad A31.
Kernel 2.4.20 LL+preemp with cardbus support in kernel.
Multiface connected and powered via AC adaptor.
I've been trying alsa-driver-0.9.4, and I detail my setup and
problems below:
snd-hammerfall-mem loads normally
snd-hdsp first stage loads fine (dmesg output snip):
PCI: Setting latency timer of device 06:00.0 to 64
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:4110: card initialization pending :
waiting for firmware
------------------
# hdsploader
hdsploader - firmware loader for RME Hammerfall DSP cards
Looking for HDSP + Multiface or Digiface cards :
Card 0 : RME Hammerfall DSP at 0x31000000, irq 9
Upload firmware for card hw:0
Hwdep ioctl error on card hw:0 : Input/output error.
------------------------
dmesg snippet while hdsploader ran with extra debugging added by
me:
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:644: wait for FIFO status <= 0 failed after
30 iterations
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:3804: initializing firmware upload
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:522: loading firmware
....
the code in snd_hdsp_create_alsa_devices() is executed here,
successfully up until snd_hdsp_set_defaults() is called. In that
function, the loop where the gains for the matrix mixer are
silenced executes hdsp_write_gain 128 times, and on the next
iteration the following message is thrown:
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:644:
wait for FIFO status <= 127 failed after 5000 iterations
causing the function to return -EIO hence the ioctl error passed
back to hdsploader.
Any attempts to run hdsploader again result in more errors
involving FIFO timeouts, getting worse until the following
message is thrown every time:
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:3804: initializing firmware upload
ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:508: Hammerfall-DSP: no Digiface or
Multiface connected!
Unloading the modules, and ejecting and reinserting the card
doesn't help matters, nor does a warm reboot. I do not have
windows on the laptop (yet) so I have not attempted to get it
working there (to load the multiface firmware, then warm boot) or
to downgrade the hdsp firmware to 0a. Ideally, I can help to
debug the primary problems with recent HDSP and recent ALSA.... I
don't *need* to use the hardware right away (but I would like
to :)
If there is any offlist discussion about the HDSP debugging,
please include me in those messages.
D R Holsbeck, what version of ALSA, and what HDSP firmware
are you successfully using on your A31? I know you have the
Digiface though... I have the multiface.
Paul, any info you have on the initialization steps or iobox
identification would be useful. The code in
hdsp_get_iobox_version() seems a bit odd to me. I always get
the: ALSA ../../alsa-kernel/pci/rme9652/hdsp.c:644:
wait for FIFO status <= 0 failed after 30 iterations
in the primary conditional where it picks multiface or digiface.
I suppose that is intentional, but I wonder if that technique
masks some other problem, even though I do have a multiface. How
does that sequence work?
I want to get this crap working so I can test ardour better
:)
