About using compact flash with mp3 files?

Can i use the compact flash for storing mp3 files and accessing them in the niosII IDE,, is there anything i must keep in mind in this process? Thanks

Hello,

a CompactFlash card behaves in the same ways like a harddisk. Before using a HDD with a PC you have to format it with a filesystem like FAT, NTFS, … It is also possible to store data in raw format without a filesystem. But no operating system will work with the HDD. If you want to exchange data like mp3s (PC <-> Nios) you should use a filesystem. FAT16 is a very simple one. A lot of small mp3 player projects in the web are suing a FAT16 filesystem together with a HDD, CompactFlash, …

It is possible to simulate the behaviour of a CompactFlash card with the the Nios II IDE. It is some work and of course you will need a simulation model of the CompactFlash card. I don’t know if there is a ready one in the web – perhaps you have to build your own one.
