We use JFFS2 for configuration parameters etc, cramfs for binaries etc and tmpfs for temporary data (our embedded devices typically have 4 MB flash and 16 MB RAM).

Dear All,
We are developing a embedded device based on linux. Through the development phase we used NFS. But now we want to move some filesystem which can be created in FLASH/RAM.
I have few doubts about the file system in embedded devices.
1) What is the file system which is used normally in all embedded devices? (JFFS/CRAMFS/RAM DISK)
2) We tried using RAM disk as the file system. But since our application is huge it is not able to fit into 8 MB RAM disk created. When we tried to increase the size of the RAM disk, the kernel crashes above 9 MB. We have 32 MB in our target board.
3) I dont know whether we can use cramfs.
Can anybody suggest me some ideas so that i can solve these issues?
Thanks and Regards, Nanda
