There is another query (Hope this is not Off Topic]. I am required

to start a Persistent(Very important) File system at the booloader stage and that flash file system must be present even after an OS boots up (In our case it is Linux).

1. Whether the above condition possible ?

Of course it is. This is software, so EVERYTHING is possible. It's just a matter of effort, and efficiency.

2. What are all the design considerations I must keep in mind while

designing such File Systems?

The main issue is: don't try to reinvent the wheel.

If you don't need write support, then just use the existing JFFS2 code.

If you doneed write support, then just use the existing JFFS2 code and add write support to it based on the existing Linux MTD/JFFS2 drivers.
