pcxhrloader - Firmware loader for Digigram pcxhr compatible soundcards
|

|
||
|
|
GENERAL
|
||
|
|
=======
|
||
|
|
|
||
|
|
pcxhrloader is a helper program to load the firmware binaries
|
||
|
|
onto Digigram's pcxhr compatible board sound drivers.
|
||
|
|
The following modules require this program:
|
||
|
|
snd-pcxhr
|
||
|
|
These drivers don't work properly at all until the certain firmwares
|
||
|
|
are loaded, i.e. no PCM nor mixer devices will appear.
|
||
|
|
|
||
|
|
|
||
|
|
USAGE
|
||
|
|
=====
|
||
|
|
|
||
|
|
When pcxhrloader is invoked without options, it will probe all existing
|
||
|
|
soundcards until a valid pcxhr-driver is found. If a valid pcxhr-driver is
|
||
|
|
found, pcxhrloader reads the board type from the driver. The corresponding
|
||
|
|
firmware binaries are then read and transferred to the driver.
|
||
|
|
Finally, pcxhrloader initializes the PCM and the mixer devices on the
|
||
|
|
driver for making the soundcard full functional.
|
||
|
|
|
||
|
|
Instead of auto-probing, you can specify the card number or the hwdep
|
||
|
|
device name via -c and -D options, respectively.
|
||
|
|
|
||
|
|
% pcxhrloader -c 1
|
||
|
|
% pcxhrloader -D hw:0
|
||
|
|
|
||
|
|
For loading the firmware automatically after the module is loaded, use
|
||
|
|
the post-install command. For example, add the following entry to
|
||
|
|
/etc/modules.conf for pcxhr driver:
|
||
|
|
|
||
|
|
post-install snd-pcxhr /usr/bin/pcxhrloader
|
||
|
|
|
||
|
|
FILES
|
||
|
|
=====
|
||
|
|
|
||
|
|
The firmware binaries are installed on /usr/share/alsa/firmware/pcxhrloader
|
||
|
|
(or /usr/local/share/alsa/firmware/pcxhrloader, depending to the prefix
|
||
|
|
option of configure). There will be *.conf files, which define the dsp image
|
||
|
|
files for each different card type.
