The
SansaE200Port page has text on it that states...
FM Radio DONE - Functional as of 06-06-2007. The driver still needs tweaking, but it's working.I am curious as to what tweaking it needs. I have a v1 model and was successful in downloading and building Rockbox on my Ubuntu Linux machine. I am an ARM programmer and desire to try my hand at doing the "tweaks" that are necessary.
As far as I can tell, the FM Radio runs fine under Rockbox, so I need to know what needs tweaking. (Thanks!)
