Hi Jörg,

I did a lot of changes as explained at
http://www.ethernut.de/en/documents/ntn-6_spi.html

However, these routines are implemented in new modules, using a new API.
The old version should still work.

Unfortunately the SourceForge SVN web interface currently shows an old
state, but from my local copy I cannot see any related change from 4.8.2
to 4.8.3.

Btw. the new project
http://sourceforge.net/projects/ewebradio/
uses this new SPI interface. The amazing result is, that the code can be
build for all Ethernuts (including 8 bit AVRs), the EIR and for the ARM9
based AT91SAM9260-EK.

We'd need this infos. What version did you upgrade to 4.8.3 exactly?

No need to disable it. If you check your application's .map file, you
should not find any reference to the MP3 codec, if your application
doesn't use it. If you find one, the .map file will also be useful to
find out, which reference caused the inclusion of that code.
