2.2.2 Source Files List
This section gives short description of source files listed in the ‘rfs’ and ‘xsr’ directory.
The source files in this package are listed in
Figure 2-2, where *.c files and *.h files are
annotated on the ‘RFS’ source tree. Sample LLD code of OneNAND is tested with Apollon
customized board based on OMAP2420 core. You need to write your own code for other chipset.
