Is a File System Necessary?


Hi,

I am designing an I/O controller which needs to communicate over Ethernet with UDP. Since this is so minimal, is it possible to make a "kernel only" embedded Linux project with no file system?

Are there examples of this?

Alternatives would be FreeRTOS or uCOS which would fit this model. Has anyone worked with these?

Thank you,

Mark

i thought about this for a large capacity pda with a hard drive in it controled by a wdc-6502. on a machine level it is possible.

i used to have a .pdf that described the machine instuctions/ registers/ and bit-wise operations to control it.

You don't need spinning media, if that's what you mean. A small ramdisk is probably sufficient for what you need. That's normally part of the boot process already (initrd).
