OK, did some more research and can hereby confirm the breaking point was on Feb 11th as said earlier.
Release 16256 works (given by SVN when requested for Feb 10th)
Release 16276 doesn't work (dito for Feb 11th)
Learning as I speak, found where to check versions on the web page and I strongly suspect the problem was introduced on revision 16259 as it touches a lot from the core on the ipod.http://svn.rockbox.org/viewvc.cgi?view=rev&revision=16259
"Disables much of the remaining unneeded hardware on PP50xx targets (Ipods, Sansa, H10s, etc) resulting in a large savings in power and consequent increase in battery life. Results vary from target to target and from codec to codec, but we now approach the OF runtime on several PP devices."
We seem closer, but this is where I should stop since I don't have programming skills, unless someone guides me on what to do.
