Thanks. I didn't see those posts earlier. Kevin, will your patches work with
dvevm version 1.10; I see that your patches reference version 1.00. I'll
give it a try. I not interested in the video stuff (just do some audio
compression using the DSP) so hopefully I don't have to spend much effort.
Yeah, I would have been fine with the Montavista version but
I couldn't get the MTD NOR JFFS2 support to work with it; with the GIT
kernel, I got the MTD NOR JFFS2 to work fine but now I'm having to face
recompiling cmemk and dsplinkk.
Regards,
Andy

Subject: RE: Problem compiling cmemk with GIT kernel
Building cmemk.ko and dsplinkk.ko for the GIT kernel is not a
straight-forward task. Two weeks ago, I went through exactly what you're
going through now. After a few frustrating days attempting to build these
modules, I gave up and decided to revert to the montavista kernel for the
time being.
Please see a post entitled "Building cmemk.ko and dsplinkk.ko" which I
posted on the 28th of February 2007. Kevin's advice and patch files were
extremely helpful, and will probably solve your current problems, if you are
confident enough at patching/hacking source files.
Good luck,
Bobby
