Subject: Re: Compiling IPod with 64MB memory

Re: Compiling IPod with 64MB memory

From: <postmaster_at_diffenbach.org>
Date: 2006-02-27

I followed your advice (and I already had: I'd done a make clean,
followed by make and make zip, and had copied that over to the ipod
before I made my initial email, but just to be sure, I created a new
build directory and compiled anew.)

The codecs on the iPod are the same as the codecs from the 64MB build,
but the codecs still fail ("Codec failed") and the plugins still give
"Incompatible model".

Below you can see the md5sums of the 32MB build codecs (in build), the
64MB codecs (in buildIPODG5) and on the ipod (/cydrive/j):
