Are you absolutely sure that the PortalPlayer IIS can handle 24 bits
96kHz? I'm not so sure about that.
The problem I am currently having is with the FIQ
interrupt. I have used quite a bit of code from pcm-pp.c and pcm.c but
I may have missed something. If I disable the interrupt or the codec
then it all runs fin, but obviously doesn't record anything. When I
enable the interrupt and the codec it crashes. Since I have to run this
on the actual hardware its hard to debug. How is the fiq_handler
inserted into the table? Is it just done when it is defined as in
pcm-pp.c?
It is done by the linker at compile time.
Your plugin uses direct calls into the rockbox firmware, trying to
bypass the plugin API. This is doomed to not work at all. If the only
reason you do this is 24-bit 96kHz recording, why not submit a patch so
we can include that in the core, and let you use the regular recording API?
