I have an assignment in which I have to port USB code for the LPC2468
Host. I have decided to go opensource. I have taken the code for USB
from the Linux Opensource Libraries namely usb_utils. I have the code.
Now how do I proceed. My main application is to take data from another
application residing on the IC memory and store this data to a pendrive
with FAT16 or FAT32 filesystem. I am totally new in this area; I am a
student. I have only worked with ATMega32 and Intel 8x51 line of
controllers before. Please provide me with pointers and howto's. Please
give me general approach on how to tackle this problem and what problem
areas I should look out for.
LPC2468 USB and FAT32 interfacing

Linux usb_utils provides middle-level routines to handle OHCI. But I recommend
you to start with this NXP example, because it also supplies full low-level
routines, directly access to the LPC2468 OHCI controller.
USBHostLite from NXP
http://www.standardics.nxp.com/support/software/usb.host.msc/
USBHostLite for LPC23xx/LPC24xx, VBeta 1.0 (Feb 11, 2008)
http://www.standardics.nxp.com/support/documents/microcontrollers/zip/usb.host.lite.zip
This example includes FAT16 file system support.
To extend it to FAT32, you may be interested in this file system implementation.
