Well, I had _not_ to create any extra/additional config files.
- I fetched alsa-lib and alsa-tools source packages (at that time I used
1.0.13 and later 1.0.14).
- I used ELDK 4.0 for PPC405 as cross-compiler environment. <rootdir> is
the root directory used by the ML403 board.
- Compiled alsa-lib:
$ ./configure --host=powerpc-linux
$ make
$ make DESTDIR=<rootdir> install
- Compiled alsa-tools (linked against alsa-lib)
$ ./configure --host=powerpc-linux \
--with-alsa-inc-prefix=<rootdir>/usr/include \
--with-alsa-prefix=<rootdir>/usr/lib
$ make
$ make DESTDIR=<rootdir> install
- Login to board, modprobe my driver
- Make sure udev is running and created /dev/snd/* files OR
- Create /dev/snd/* files with snddevices script from alsa-tools
package
- alsamixer (adjust volume), aplay somefile.wav
So, that's it - but I'm afraid that this won't help you. I never touched
any files installed by "make install" of both packages.
