Just make sure to check your FW version. You'll want to be using one 4.xx See here also http://iaudiophile.net/forums/showthread.php?t=25285
I have a D2+ dab with firmware 4.13I can't find a Rockbox version for my player.Will it ever come?
so could anybody tell me which files of the sources' code should be concerned?
It seems USB on the TCC chips is fairly well along, so hopefully with the datasheet and some debugging it can be made to work.
Looking at my D2 build, it seems IRAM isn't used for codecs. Is there a reason for this? I see its in the lds file.

I see its in the lds file.When I first started the port, I did have IRAM working and used for codecs, but for some unknown reason performance was actually worse than without. It was never investigated fully, so IRAM remains disabled.
