USBHostLite includes just FAT16 file system library. Replace it to another one, such as FatFs (FAT12, FAT16 and FAT32) elm-chan.org/.../00index_e.html
Here is an example of FatFs over USBHostLite (LPC17xx).
Interfacing ARM controllers with Memory-Cards www.siwawi.arubi.uni-kl.de/.../index.html Find "ChaN's FAT-Module with LPC17xx SPI/SSP and USB-MSD" paragraph near the bottom.
Above mentioned information, I have gathered from one of the replies in Keil forum. I didn't get the sample codes as mentioned in the comment. First website have a list of file functions and a few links to some blogs and codes. But, I am not sure which one i should refer.
The second mentioned link leads to some German university website.
Can someone please explain.
